  • The inlet baffle should extend at least 6 inches, but no more than 12 inches into the liquid level of the tank. The inlet baffle should extend 12 inches above the liquid level of the tank. This is a total baffle length of 18 to 24 inches.

Why is my septic tank filling up so fast?

If your tank seems to be filling up much more quickly, it could indicate a problem with one of its components, or it could be a sign that your tank is taking on more liquids than it can handle. Call a local professional if your tank is needing more septic pumping than usual.

How deep should a septic baffle be?

The inlet baffle should extend at least six inches below the invert of the pipe, but no more than 20% of the liquid depth. The outlet baffle should extend between 35 and 40% of the liquid depth.

Do septic tanks have two inlets?

Septic tanks, whether made of concrete, fiberglass, or plastic, are designed with a single inlet and outlet opening at the inlet and outlet ends of the tank.

Should outlet be lower than inlet on septic tank?

Inlet & Outlet Pipes: Wastewater from your home enters the septic tank through the inlet pipe. After the solids settle out, effluent leaves the septic tank through the outlet pipe and flows to the drain field. The outlet pipe should be approximately 3 inches below the inlet pipe.

How long does it take for a 1000 gallon septic tank to fill up?

A family of four will fill the 300-gallon storage volume of a 1,000-gallon septic tank in about 1.5 years. By making adjustments in this analysis for adults working outside of the home a third of the time and children going to school, it is easy to conclude that a septic tank should be pumped every two to three years.

Can heavy rain affect septic tank?

It is common to have a septic back up after or even during a heavy rain. Significant rainfall can quickly flood the ground around the soil absorption area (drainfield) leaving it saturated, making it impossible for water to flow out of your septic system.

How long should an inlet baffle be?

The inlet baffle should extend at least 6 inches, but no more than 12 inches into the liquid level of the tank. The inlet baffle should extend 12 inches above the liquid level of the tank. This is a total baffle length of 18 to 24 inches.

How long does a septic baffle last?

Inspectapedia estimates that a steel tank baffles will rust out in 15 to 20 years and may collapse if driven over, but a concrete tank will last 40 years or more as long as the wastewater is not acidic. It’s important to consider the life expectancy of a drain-field, too.

How many inlets does a septic tank have?

Every septic tank contains two baffles, one at the inlet and one at the outlet. The goal of both baffles involves routing waste water through the tank, while ensuring that solids remain safely segregated.

How deep is the septic tank inlet pipe?

A typical septic tank has a 4-inch inlet located at the top. The pipe that connects to it must maintain a 1/4-inch-per-foot slope toward it from the house. This means that for every 10 feet of distance between the tank and the house, the inlet must be 2 1/2 inches below the point at which the pipe exits the house.

Why is there a baffle in a septic tank?

The inlet baffle directs the flow of wastewater into your septic tank, and prevents the scum layer in the tank from being disturbed. It also can help prevent solids from backing up toward the house if you should experience a septic system backup.

How much does it cost to replace a baffle in a septic tank?

Repairing a baffle costs $300 to $900 on average. You may pay more if it’s tough to access. The baffle helps to prevent buildup in the incoming or outgoing pipes of the tank.

What is a baffle tee?

Baffle Tees Block Floating Scum And Debris From Flowing Out Of Septic Tanks Into The Outlet Line To Prevent Clogging Drain Fields. Baffle Tees are designed for hi-line end and slip joint end outlet waste connections. Plumbing fittings are made of polypropylene plastic for long lasting durability.

How often pump septic tank?

Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.

Question:

According to my ten years of experience, the scum layer in a septic tank is heaviest at the intake end and thins down significantly at the output end, probably by half, if not more. In addition, the intake pipe reaches approximately one-third of the way vertically into the tank, and the outflow pipe extends approximately half of the way vertically. Therefore, an enormous scum layer (more than 12 inches) frequently limits sewage flow into the tank — even to the point of completely sealing it off — long before the output line reaches its maximum capacity.

In addition, I’ve discovered that the bottom sludge layer is very evenly dispersed.

Answer:

The practice of measuring the thickness of the scum layer and informing the public is a smart one to follow. The most important location, however, is at the exit baffle to ensure that scum or sludge does not enter the soil treatment unit throughout the process. According to your remarks, it appears that the standards for baffle submergence in your region differ from those that we employ in Minnesota. First and foremost, I’ll go through the measurements that Minnesota utilizes for septic tank baffle submergence and baffle extension above the liquid level.

  1. We’ve taken those findings and included them into Minnesota’s septic tank requirements.
  2. Septic tanks should be built such that their length is two to three times longer than their breadth.
  3. The liquid depth of the septic tank, denoted by the letter D, serves as the foundation for all other tank parameters.
  4. The top of these baffles must not be closer than 1 inch to the tank cover in order to function properly.
  5. The input baffles must protrude at least 6 inches into the liquid level, but not more than 0.2D below the surface of the liquid.

The invert (bottom) of the home sewage system must be at least 3 inches above the liquid level of the septic tank to function properly. As a result, the entering sewage will have a downward velocity, which will allow the scum to be transported down and out past the bottom of the entrance baffle.

PUMPING RECOMMENDATIONS

Taking measurements of the thickness of the scum layer and informing clients is a good practice. In order to prevent scum or sludge from being discharged into the soil treatment unit, the exit baffle is a vital point of contact. According to your remarks, it appears that the standards for baffle submergence in your region differ from the ones that we use here in Minnesota. As a starting point, I’ll go over the measurements that Minnesota utilizes for septic tank baffle submergence and baffle extension above the liquid level.

  • Septic tank requirements for Minnesota have been developed in part on these findings.
  • Septic tanks should be two to three times longer than they are wide, according to the EPA guidelines.
  • For other tank measurements, the liquid depth of the septic tank, denoted by the letter D, is used as a guideline.
  • There must be no more than 1 inch of space between the top of these baffles and the tank lid.
  • At least 1 inch must be provided above the top of the input sewer pipe on either side of the baffle.
  • When the house sewer is inverted (at the bottom), it must be at least 3 inches above the liquid level in the septic tank.

REFERENCE INFORMATION

Another post I published addressed a query regarding concrete septic tanks that were in poor condition. The Precast Concrete Association of New York’s executive director, Carl S. Buchman, P.E., reacted to the allegations. A pamphlet on concrete septic tank design, fabrication, and installation is available from the National Precast Concrete Association’s website. It is titled Best Practices Manual — Precast Concrete On-Site Wastewater Tanks, and it is accessible for download. A series of Tech Notes on various elements of septic tanks was released by PCANY, according to Buchman, including testing for water tightness, correct installation and warranty information, among other things.

Buchman went on to clarify. “The National Parks Conservation Association offers a program that is comparable” (patterned after ours). It doesn’t matter to me whose certification program the tanks are certified under, as long as they all give the same quality.’

Everything You Need to Know About Your Septic Tank

What is a septic tank, and how does it work? A septic tank is a water-tight container that is often constructed of concrete, fiberglass, or polyethylene to prevent flooding (plastic). In fact, it is only one component of the entire septic system, which includes several other components such as a distribution box, pumps, float switches, aerators, filters, and other accessories. Septic systems are used to treat wastewater on-site in many rural and suburban areas that do not have access to centralized sewage systems.

The components of a conventional septic tank are depicted in the diagram below.

These are:

  1. The Tank: This is the water-tight tank into which wastewater from your house is sent once it has been collected. A hole, fracture, or any other structural damage should not be present. Access Ports: When a trained pumper comes to clean up your tank, they will utilize an access port. When it comes to tank cleaning, it is critical that the access port be large enough to allow the pumper to move the hose about within the tank properly. A common application for risers is to elevate septic tank access above ground level, eliminating the need to dig up your septic tank every time it has to be pumped. Last but not least, the access port should be securely secured with a child-resistant lid. It is vital for the protection of your family that septic tank lids are securely fastened with screws and that they are not cracked or damaged. Pipes for entering and exiting the septic tank: Wastewater from your house enters the septic tank through the intake pipe. After the particles have settled out, the effluent is discharged from the septic tank through the exit pipe and into the drainage field. There should be roughly 3 inches between the output pipe and the intake pipe. A baffle is fitted on the intake pipe within the tank, and it serves to keep the water out. It provides a variety of functions. Additionally, it helps to avoid the build-up of scum and its backup into the intake pipe It is also important for solids to settle in the tank that the input baffle be properly installed. When wastewater enters the septic tank, it should hit the entrance baffle, which will reduce the flow and prevent the tank from becoming agitated. This permits the contents of the septic tank to remain at rest, allowing the solids to sink to the bottom of the tank. The intake baffle can also prevent odorous odors from entering the sewage line and spreading throughout the home or business
  2. And It is even more crucial than the inlet baffle to have an exit baffle in place because it helps to prevent scum and other particles from flowing directly into the outflow pipe and eventually into the drain field. Gas Deflector/Effluent Filter: As gas bubbles climb to the top of a septic tank, they may bring sediments with them. This is why an effluent filter is used. A gas deflector prevents these solid-carrying gases from entering the output line by preventing them from entering. However, while not every septic tank is equipped with an effluent filter, it is strongly suggested as an additional safety to prevent particulates from entering your drain field.

Any of the above-mentioned components in your septic tank should be checked for damage or missing parts as soon as possible, and the problem should be resolved by a septic system specialist. What is the operation of a septic tank? Each and every drop of wastewater from your home is channeled via a main drainage pipe and into your septic tank. Solids are prevented from entering your drain field by using the septic tank, which is just a settling tank that serves as a filter. Ideally, the water should be kept in the tank for at least one day in order to enable time for the solids to settle.

  • Heavy materials, such as dirt and digested waste, will sink to the bottom of the tank and form a sludge layer at the bottom of the tank.
  • Effluent is the term used to describe the liquid that exists between the sludge and scum layers.
  • It is critical that solids are given adequate time and space to settle before being used.
  • In fact, the Pennsylvania Department of Environmental Protection mandates a minimum capacity of 900 gallons for any new septic tank installations in the state (the table below shows recommended septic tank capacities for different sized homes).
  • Ideally, you should have your septic tank emptied every two to three years, according to the Pennsylvania Septage Management Association (PSMA).
  • If a drain field has been ruined by a buildup of sediments, it might cost tens of thousands of dollars to rebuild it.
  • It is crucial to understand that your septic tank must be completely filled with liquid in order to function effectively.
  • The septic tank diagram shown above depicts the correct operating level of a septic tank in a residential setting.
  • The result is that whenever more wastewater is added to the tank, an equal volume of effluent will be discharged from the tank and drain into the drain field.
  • The opposite is true if the liquid level is higher than the outflow line, which may signal a blockage in a line downstream from the septic tank or in the drain field.

If you’re wondering if your septic tank is full, a skilled pumper will consider it “full” once solids have filled one-third of the tank’s capacity. This is the time of year when your septic tank will need to be pumped.

There’s Nothing Baffling About Tank Inlet and Outlet Features

One of our colleagues showed us an image of a septic tank’s intake baffle and stated that the baffle design would result in blocking and sewage backups into the house. While this was beneficial to his pumping company, it also meant that he had to deal with dissatisfied homeowners, which was not a pleasant experience. Baffles are described as any device used in a septic tank for the purpose of retaining solid waste. Often, there are sanitary tees at the intake and effluent screens at the outflow of a water distribution system.

Even as we travel throughout the country, we continue to come across states or regions where septic tanks are not built with inlet baffles.

Inlet and outlet

Inlet baffles are critical in the operation of a septic tank because they prevent sewage from entering the tank. When they are in use, they drive wastewater collected from a home downward to the level of the clear zone, dispersing the energy of the inflowing flow to minimize turbulence and disturbance of the segregation of scum and sludge layers in the tank. The inlet baffle, in conjunction with the exit baffle, prevents inflow from short-circuiting flow through the tank, enabling sediments to settle and the clear zone to remain clean.

  • A sanitary tee connected with effluent screens is used as an outlet baffle nowadays to ensure that big materials originating from either the sludge or the scum layers do not make their way from the tank downstream to damage soil treatment units.
  • When designing or developing a system, it is critical to examine or include a number of key design and operating requirements.
  • The fact that they are sitting in the tank bottom means that they will not work.
  • Different metals or other materials with metal fasteners were shown to be less durable than others.
  • The most common types of sanitary tees that we encounter nowadays are either cast-in-place or installed sanitary tees.
  • In low-profile tanks, the entrance baffle must reach at least 6 inches below the surface of the liquid, but not more than 20 percent of the total liquid depth is permitted.
  • This enables the baffle to perform its function of guiding flow downward into the tank and away from the intake, as well as preventing any scum layer from forming.

For a rectangular tank with an operational depth of 60 inches, the baffle should extend 24 inches beyond the tank’s perimeter.

The baffle, in a similar manner as the entrance, should extend at least 6 inches above the surface of the liquid.

Maintain appropriate venting at all times.

The amount of space required to avoid clogging with toilet paper or other solids ranges from 6 to 12 inches in diameter.

The sanitary tees at the inlet are in good working order.

Conclusion When compared to the cast-in-place baffles, sanitary ties significantly minimize the likelihood of clogging difficulties.

It is possible that the gases may not be effectively evacuated, resulting in corrosion of concrete around the exit baffles and on the bottom of the cover, which will cause the baffles to deteriorate and the cover to become structurally unstable.

Design and manufacturing criteria for tanks are set out by the National Precast Concrete Association, and they should be adhered to.

3 THINGS TO KNOW ABOUT SEPTIC TANK BAFFLES

A critical purpose of a septic tank’s inlet baffles is to keep it from overflowing. When they are in use, they drive wastewater collected from a home downward to the level of the clear zone, dispersing the energy of the inflowing flow to minimize turbulence and disturbance of the segregation of the scum and sludge layers in the tank. This baffle, together with the outlet baffle, prevents inflow from short-circuiting flow through the tank, enabling sediments to settle and maintaining the clear zone during normal operation.

  1. A sanitary tee connected with effluent screens is used as an outlet baffle nowadays to guarantee that big materials originating from either the sludge or the scum layers do not make their way downstream into impact soil treatment units.
  2. When designing a system, it is critical to take into account or include a number of key design and operating requirements.
  3. If they are resting at the bottom of the tank, they will not operate.
  4. There was no evidence of durability in different metals or other materials combined with metal fasteners.
  5. Sanitary tees that have been cast in situ or that have been installed are the most common today.
  6. In low-profile tanks, the entrance baffle must reach at least 6 inches below the surface of the liquid, but not more than 20% of the total liquid depth.
  7. In this fashion, the baffle can perform its function of guiding flow downward into the tank and keeping any scum layer that has formed away from the tank’s entrance.

The baffle should be 24 inches in length for a rectangular tank with an operating depth of 60 inches.

It should extend at least 6 inches above the liquid surface, in the same manner as the intake.

Assure that appropriate ventilation is maintained.

There should be 6 to 12 inches between the toilet paper and other solids to avoid clogging.

When it comes to the inlet, sanitary tees perform well.

Conclusion When compared to the cast-in-place baffles, sanitary ties significantly reduce clogging concerns.

It is possible that the gases will not be effectively evacuated, resulting in corrosion of concrete around the exit baffles and on the bottom of the cover, causing the baffles to deteriorate and the cover to become structurally unstable.

Tank design and manufacturing guidelines established by the National Precast Concrete Association should be adhered to in the construction of tanks.

Complete Guide to Your Septic Tank

When sewage exits your home and enters your septic system, the septic tank is the first component that it comes into contact with. Eventually, all of the greywater and waste will fill the tank, and it will then flow out into your absorption area. Although the septic tank is often the most visible structure in your septic system, many people are confused about how it works. If you want to learn further more about septic systems, you can get our ebook by clicking on the link below. It includes information about septic tanks, septic systems, maintenance, and other topics.

How A Septic Tank Works

As soon as you open the lid of a septic tank, you will discover that the tank is completely full of sewage and nearly filled to the top. Typically, the first notion that comes to mind is that the tank is ready for pumping. However, this is the usual operating level at which a tank functions. As the tank fills up, it overflows down the drain field and into the ground. Many people are perplexed as to why the sewage and other trash are not simply discharged into the drain field directly. What’s the point of having tanks to fill if everything just pours out onto the field in the first place?

This may appear inconsequential, yet it is critical to the operation of a functional system.

  1. The floating solids form the topmost layer (or scum). Anaerobic bacteria did not break down any of the oils, fats, greases, or anything else that was present in the wastewater. Sludge can be found at the very bottom of the well. Septic tank pumping is necessary to remove both floating particles and sludge, which are the primary reasons for frequent septic tank cleaning. If such solids and semi-solid sludge are allowed to enter your drain field, the lifespan of your drain field will be significantly reduced. The cleared effluent is found in the space between the sludge and the floating particles. In the tank, this is the only trash that may be discharged onto the field, and it should account for the vast majority of the waste.

The anaerobic bacterium that colonizes the tank is the majority of the population. Anaerobic bacteria are any bacterium that can survive in the absence of oxygen. For this reason, it is still possible to close a septic tank lid while the waste is still able to be broken down. Because of the tank’s construction, waste can flow into the tank, where it will be collected, and then be discharged. The input pipe of a tank is meant to be approximately 3 to 4 inches above the outflow pipe of the tank.

In order to ensure that the cleared effluent departs the tank without bringing any floating particles with it, it is necessary to use baffles to accomplish this.

Baffles

It is anaerobic bacterium that colonizes the tank’s microbial population. Anaerobic bacteria are any bacteria that can survive in the absence of oxygen. You may close the lid of your septic tank and it will still be able to break down the waste. Because of the tank’s construction, waste can flow into the tank, where it will be held, and then be expelled. The input pipe of a tank is typically 3 to 4 inches higher than the outflow pipe when it is constructed. In this way, the sewage may enter the tank without backing up into the home.

This is where baffles come into play.

Inlet Observation Port

The intake observation port is the first component of your tank that you may be able to observe.

This is normally a 4 inch pipe with a white cover on the end to protect the end fitting. The mower will locate the item if you haven’t already done so. Despite the fact that they might be a nuisance when mowing, they are beneficial for a variety of reasons.

  1. They serve to identify the location of the tank. The inlet observation port may also be used to return via the house if someone is examining your sewer line and cannot reach it from the house. This saves a significant amount of time when pumping out your tank or inspecting the system. Aside from that, the intake observation port is quite handy for checking for any unneeded trickles into your septic system. Check to see if there are any slow trickles flowing into the septic system after making sure it has been at least 20 minutes since something has drained into it. This is something you should conduct around twice a year to ensure that everything is functioning properly.

Septic Tank Lid

Just beyond your intake observation port will be your septic tank lid, which will be located just beyond that. This covers the manhole in the center of your tank’s interior. This is the location where all pumping should take place. It has a huge aperture ranging in size from 18″ to 24″ and occasionally even greater. Having a septic tank lid on your lawn is something that many people do not enjoy. However, if it is clearly visible, it may save your pumper a significant amount of time and, perhaps, money.

  • If the lid is too low during a house sale, an inspector will ask that the lid be raised to a level that is closer to the surface of the soil.
  • This is helpful for maintenance purposes, as well as so that you may divulge their location if you decide to sell your property in the future.
  • If concrete lids are not set back into place carefully, they may crack.
  • Over time, this might put additional strain on your drainage system.

Septic Tank Pumping

We often get asked “how often should I pump my tank,” which is another frequently asked topic. The answer is straightforward: at the absolute least, it should be done every two years. When it comes to having your septic tank pumped, there are a few things to keep an eye out for that are very crucial. Remember that the purpose of pumping is to remove the floating particles on top of the water and the sludge at the bottom of the water. In order to accomplish this, a pumper must get access to the manhole in the center of the tank.

The center manhole can also assist them in seeing considerably more of the tank and determining whether or not a significant amount of the solids has been removed.

This can cause your input baffle to become detached, resulting in the pumper being unable to detect the quantity of solids remaining in the tank.

A good pumper will back flush some of the water he has pumped out in order to mix up the sediments in the bottom of the tank, and then vacuum up the remaining water.

After everything has been pumped out, they may look inside the tank with a flashlight to see if there are any fractures, roots, or degeneration below the level of the prior liquid. Please contact us to book an appointment to have a dependable pumper come to your location.

Different Types of Septic Tanks

There is a wide variety of septic tanks that may be provided to customers. Therefore, it is critical to pose the question “What type of septic tank do I have?” before proceeding. Some of the most often encountered are listed below.

Primary and Secondary Tanks

In 1997, the state of Pennsylvania mandated that all new systems be equipped with a secondary settling tank. Therefore, if you were to repair your drainfield and apply for a permit, you would also be required to install a second tank. The reasons behind this was that while the first tank was settling all of the solids, there was still some that was flowing over into the drain field after it was filled. With this second tank, the solids could be settled and more waste could be broken down, resulting in a more efficient treatment process.

See also:  How Long Before Pumping Out A Septic Tank? (Solution)

The secondary tank is normally situated immediately following the primary tank.

If you had a fully new septic system done after 1997, there is a good chance that your installer selected a less expensive option than two tank installation.

Dual-chamber Septic Tank

Instead of using separate tanks, a dual-chamber tank makes use of chambers. A enormous rectangular tank with a wall in the middle is what you’ll find here. A 1,250-gallon dual-chamber tank is a standard size for this type of tank. The first compartment contains 750 gallons, while the second chamber stores 500 gallons. The most significant advantage of a dual-chamber septic tank is the cost savings associated with its installation. There is only one hole to dig, and only one tank to put in it.

  1. When a new system is installed, these are the first things to look for.
  2. If you have a dual-chamber tank, be sure that both chambers have been drained out before continuing.
  3. The lid of the second chamber is sometimes buried deeper than the lid of the first compartment.
  4. Being aware that you have a dual-chamber tank and that there are two lids will assist you in keeping your system in good working order.

Holding Tank

Instead of having two distinct tanks, a dual-chamber tank has chambers. A enormous rectangular tank with a wall in the middle is what we’re talking about here. Tanks with two chambers are typically 1,250 gallons in capacity. In the first compartment, there is space for 750 gallons and another 500 gallons in the second chamber. It is the lower cost of installation that is the most significant advantage of a dual-chamber septic tank. One hole must be dug and one tank must be placed in the ground.

An installation will propose a dual-chamber tank unless the original tank is in excellent condition.

For pumping, they should be in close proximity to one another.

Because of this, a pumper may believe that there is just one chamber to pump out. Being aware that you have a dual-chamber tank and that there are two lids might assist you in keeping your system in good working order,

Cesspool

If you have a cesspool, it is possible that you do not have a septic tank. This is due to the fact that a cesspool may serve as both a septic tank and an absorption area. They are a form of septic system that is no longer in use and is considered outdated. Cesspools are created by excavating a large pit. It was assembled into a big cylindrical building with cinder block along the sides and open soil on the bottom, which was constructed by an installer. The cinder blocks are stacked one on top of the other with no mortar in between the layers.

When the dirt at the bottom of the cesspool is unable to drain properly, the cesspool begins to fill.

At this moment, the cesspool is no longer functional due to its deterioration.

Solids will ultimately accumulate in the soil and prevent it from draining properly.

Aerobic Tank

Anaerobic bacteria are present in all of the tanks that we have discussed so far, and these bacteria help to break down waste before it enters the drain field. The aerobic tank is used to treat sewage by introducing aerobic microorganisms into the system. Anaerobic bacteria, as we well know, flourish in an environment where there is no oxygen. Aerobic tanks provide airflow, which allows bacteria that use oxygen (aerobic bacteria) to flourish. Two additional components are included in the tank to facilitate the growth of aerobic bacteria: a system for generating air supply and propagation medium (usually a honeycombed structure).

The air supply is responsible for introducing oxygen into the tank.

The anaerobic bacteria found in conventional systems contribute to sludge formation and have the potential to draw oxygen from the soil, impairing the soil’s capacity to drain.

Septic Tank Problems

Septic tanks are constructed to last for many years. The tank maker pours them so that they are approximately 3 inches thick. There is a 25-year warranty on them, which is a considerable period of time, but not an eternity. Eventually, indicators of degradation begin to appear in the tank’s condition. This can take many different forms, but the following are the most prevalent.

Chemical Reaction

Construction of septic tanks is quite durable. Approximately 3 inches thick is what the tank maker dumps into the tanks.

There is a 25-year warranty on them, which is a long period but not indefinitely. Eventually, traces of degradation begin to appear in the tank’s appearance. Many other variations exist, however the following are the most often encountered:

Exposed Rebar

The rebar can become exposed as a result of the concrete eroding and revealing the rebar over time. This is a significant red flag for septic inspectors who are looking into the situation. If an inspector notices exposed or corroded rebar in a tank, he or she will declare the tank unacceptable. You can tell that the concrete in the tank has gone mushy and is collapsing when you see the rebar sticking out of it.

Deteriorated Baffles

Many tanks are equipped with concrete baffles that protrude into the tank. As a result of their greater surface area exposed to the chemical reactions induced by bacteria, baffles are typically the first component within the tank to fail. When the baffles fail, you lose the ability to perform critical functions. The output baffle is the most critical of the three. If there is no exit baffle, there is nothing to prevent the sediments from floating out into the drain field and into the environment.

Cracks in the Tank

There may be a few feet of dirt cover on top of the tank when it is installed in the ground by a professional installation company. The earth on top of the tank adds a large amount of weight to the structure. Over time, this weight, along with the chemical reaction in the tank, which weakens the tank’s construction, can cause fractures to appear in the tank’s structure. They often begin at the very top of the tank. The greater the depth to which the tank is buried, the greater the likelihood that a fracture would develop.

Root Intrusion

Planting trees and huge shrubs directly next to sewage tanks is something that many people do on purpose. They may have planted plants to assist beautify their environment, but they may have done so without realizing it, putting the construction of their tanks at risk. The tree roots will begin to burst through the concrete tanks, causing structural damage to the structures beneath. Although it may appear strange, a tree has the ability to cut through thick concrete. However, after time, the thin roots penetrate the tank walls and cause damage.

  • The development of the roots will result in cracking and, eventually, the tank will collapse.
  • It is possible to engage a professional to cut the roots and remove them from the tank while they are still thin.
  • By now, you should have a solid foundation of knowledge about septic tanks under your belt.
  • This will aid you in the maintenance of your system as well as the purchase or sale of a new property.

Septic System Knowledge 101: Inlet and Outlet Baffles

While your septic tank is a critical component of your septic system, your baffles are as crucial – in fact, missing baffles can result in significant damage to your system. Posted on So, what exactly is a baffle? In simple terms, it is a mechanism that controls the flow of wastewater into and out of your septic tank. Tees are generally built of clay, concrete, or PVC pipe, and they are often referred to as “tees” in the industry.

The inlet baffle

When wastewater enters your septic tank through an inlet baffle, it is prevented from being disturbed, which helps to keep your septic tank running smoothly. It can also assist in preventing sediments from backing up toward the house if you should encounter a septic system backup at your home or business. A missing intake baffle does not usually have an impact on the general operability of the system, but it is necessary by TCEQ standards in order for the system to function.

The outlet baffle

The outlet baffle is also essential, and it plays a critical role in the process. If you want your system to work correctly, it has to be present. By directing effluent from the tank to the drainfield, it avoids the scum layer from entering the outlet pipe directly and producing drainfield obstructions and system failure before it is necessary.

Baffle installation is not guaranteed

Despite the fact that TCEQ laws mandate that every septic system be equipped with an inlet and outlet baffle, we frequently enter a septic tank and discover that one or both of these baffles are absent. Look into the tank to find out; in some circumstances we have to pump the tank first before we can see what is going on. When we notice that a baffle is missing, we inspect the bottom of the tank while it is being pumped to check whether the baffle has fallen off accidentally. Because there is no evidence of a baffle being there yet it is not at the bottom of the tank, the presumption may be made that it was never put.

If you have a septic tank that is pumped on a regular basis, the pumping specialist should be inspecting the baffles.

WAC 246-272C-0220:

(1)Compartments for septic tanks. Septic tanks must be planned and built with a minimum of two compartments in order to be effective. It is possible to meet this specification with a single tank with two compartments or by connecting two single compartment tanks together in sequence. At least one-half but no more than two-thirds of the total needed liquid volume must be accommodated in the first compartment, and the remaining portion of the total required liquid volume must be accommodated in both the first and second compartments.

The following requirements must be met by septic tank inlets: (1) The inlet pipe’s sanitary tee or baffle extends at least eight inches downward below the liquid level; (2) The pipe’s inlet sanitary tee or baffle extends above the liquid surface at least as far as its inlet crown; and (3) The pipe’s invert is at least two inches higher than the pipe’s invert at the tank outlet.

The following requirements must be met by septic tank outlets: For horizontal cylindrical tanks, the outlet sanitary tee or baffle must extend below the liquid level by at least thirty percent, but not more than forty percent, of the liquid depth; and (c) the outlet sanitary tee or baffle must extend below the liquid level by at least twenty-five percent, but not more than thirty-five percent, of the liquid depth.

For ventilation purposes, the outlet tee may be extended into the riser.

In order to accept effluent screening devices or filters, septic tanks must be built and constructed in a manner that allows for their installation.

Chapter 246-272A or 246-272BWAC include specific effluent screen or filter criteria or standards, if any, that must be met.

If the tank has straight vertical sides, the intercompartmental wall fittings must extend below the liquid level at least: I thirty percent, but not more than forty percent, of the liquid depth; or (ii) twenty-five percent, but not more than thirty-five percent, of the liquid depth if the tank is cylindrical with horizontal sides.

I The slot or port must be located at the same depth as the bottom of the outlet tees or baffles; and (ii) the aperture must have a minimum area of twelve square inches and a minimum vertical dimension of three inches in order to comply with the requirements.

In order to prevent solids from moving from one compartment to another, the septic tank must have intercompartmental walls that: (a) prevent solids from moving from one compartment to another except through the intercompartmental wall fittings; and (b) withstand pumping of the adjacent compartment without risking structural damage or functional failure.

There must be sufficient air space volume in the septic tank for scum storage, which must be at least 10% of the total liquid volume of the tank.

(8)The length to breadth ratio of a septic tank.

(b) A septic tank with a liquid capacity greater than three thousand gallons must be at least 1.25 times its length.

For septic tanks with liquid capacities higher than or equal to three thousand gallons, the length of the tank must be at least 1.5 times the breadth. (9)The depth of the liquid capacity of the septic tank. Septic tanks must have a liquid depth of at least three feet to be considered functional.

These requirements must be met by septic tank inlets: (1) The inlet pipe’s sanitary tee or baffle extends at least eight inches downward below the liquid level; (2) The pipe’s inlet sanitary tee or baffle extends above the liquid surface at least as far as its inlet crown; and (3) The pipe’s invert is at least two inches higher than the pipe’s invert at its tank outlet.

  • To allow for venting, the outlet tee can be extended into the riser.
  • During the design phase of on-site sewage systems, the department and local health inspectors are urged to examine the usage of effluent screens or filters on a case-by-case basis.
  • (5)Intercompartmental wall fittings for a septic tank installation.

FAQs — JT’s SEPTIC

Make sure to contact JT’s Septic as soon as possible! It is possible for us to assist you in diagnosing the problem and determining if it is a plumbing issue or a problem directly connected to your septic system. Wastewater backing up into more than one household fixture (even during dry weather), pooling water or muddy soil around your septic system or in your basement are all signs that your system needs to be checked. If you notice any of the following, contact us to have it checked: a strong odor around the septic tank and/or drainfield

Should I Use Septic Tank Additives?

According to current research, there is no clear proof that these items can prevent septic system failure or that they will improve system function. The addition of compounds to a septic tank will not eliminate the necessity for routine tank cleaning. Septic tank cleansers, rejuvenators, and primers that are promoted as such will not hurt your system, but they will not benefit it either. However, there is already a large amount of bacteria in the tank that will break down waste products, so using enzymes or yeast would not hurt your system at all.

Septic system additives should be avoided, according to the North Dakota State University Agriculture Communication.

what are the PVC pipes sticking up in my yard?

Septic tank cleanouts are often located between the home and the septic tank, and they are used to snake the input line from the house to the tank. If the PVC markers are labeled with “JT’s Septic,” they indicate that they are marking the access lids to your septic tank (buried directly under the labels). Alternatively, if the pipes are further away and appear to be arbitrarily arranged in relation to the house or tank, it is possible that they are inspection ports used to check the amount of liquid in the disposal area.

will household cleaning products harm my system?

Septic tank cleanouts are often located between the home and the septic tank, and they are used to snake the input line from the house toward the tank. They identify the access lids to your septic tank if the PVC markers have the label “JT’s Septic” on them (buried directly under the labels). Depending on how far the pipes are from the home or tank and how they appear to be randomly positioned, they might be inspection ports for monitoring the liquid level in the disposal area. Visit ourCOMPONENTSpage for additional information on the various septic tank components.

How Often Should I Pump My Septic Tank?

Most tanks require pumping every 3-5 years, depending on the size of the tank, the amount of wastewater that flows into the tank on a daily basis, and whether or not the tank is equipped with a trash disposal. The state of Arizona currently does not have any laws requiring maintenance and inspection (with the exception of those pertaining to the sale of a home), but the Environmental Protection Agency and local health departments strongly recommend routine maintenance to help prevent groundwater contamination due to nitrogen, phosphorus, and disease-causing bacteria that can be found in wastewater.

I just had my tank pumped and it already looks full!?!

There is a distinction between being full and being overfull! An empty septic tank will fill up as quickly as you use up the quantity of gallons it can contain in terms of water use. The tank is designed to maintain a liquid level at or near the bottom of the outflow pipe at all times. (that exits into the disposal area). When you look down into your tank, it should appear to be completely filled. It is necessary to hire an expert to assess the quantity of scum and sludge in your tank in order to decide when it is time to pump it out.

Does anyone have to be home to have jt’s pump my septic tank?

We usually advise people to have someone at their house for our service, but it is not mandatory. Our service technicians are quick and fast when it comes to finding and pumping out a problem. We enjoy having a homeowner and/or a Realtor on site for our inspections so that they may discuss any concerns that we may discover.

Does JT’s Septic do leach line work?

At this time, JT’s does not install or do any work on leach lines or disposal locations. We do minor repairs on septic tanks, as well as on the inlet and outlet sewer lines. Not sure if we can assist you? Just give us a call!

Why can’t you pump my septic tank out of the sewer cleanouts?

We have found that a tank cannot be efficiently pumped through sewage cleanouts because the pumps on our trucks are just too powerful, and there is no way to get all of the scum and debris out of the tank through a cleanout. It is advised that the tank access lids be used in order to remove all liquid and particles from the tank and to examine the baffles. To empty the tank completely, we unlock all compartments and use a pump to remove the full contents of it. The fact that you do not pump via the primary access holes in the tank itself is a disservice to yourself and your system.

how do you know the size of my tank?

Our experts and inspectors can identify the size of the tank based on the form of the tank; tanks for a normal residence are generally 1,000 or 1,250 gallons in capacity, respectively (tanks may be smaller or larger depending on bedroom count, style of tank, etc). Our trucks are outfitted with clear sight glasses, allowing our specialists to keep track of the number of gallons they are extracting from your tank. Our specialists are also trained to measure the tank measurements on the job site in order to establish the approximate gallon capacity.

why do you recommend routine maintenance and frequent pump outs when I’ve not a had a problem in the last 10 years and I’ve never had my tank pumped?

Even while many homeowners are able to go several years over the suggested maintenance time without experiencing any problems, harm is gradually being done. Solids that are insoluble in water and cannot be broken down by natural microbes are stored in the tank. This builds up over time until the tank no longer has enough space to hold everything. As a result, the solids make their way to the drain field where they fill up the pores in the earth, causing poor drainage and, eventually, the failure of the septic system and drainfield.

How long will my septic system last?

All septic systems have a defined life span, which means they will ultimately cease to function.

The length of time a system will survive is determined by the system’s size, installation, soil composition, the water table, neighboring trees and roots, the amount of usage and abuse, and, most crucially, the frequency with which it is maintained and pumped.

if I have a garbage disposal Can i use it?

Yes! It is OK to use the garbage disposal for a limited amount of time, such as for food crumbs that remain after doing the dishes. Pump outs will be more frequent if the disposal is used more frequently, which will result in higher costs. The usage of a trash disposal can have a negative impact on your septic system by increasing the quantity of suspended particles that enter the system. Soil treatment areas can get clogged with suspended particles, which reduces the soil’s ability to remove waste.

CAN I FLUSH WET WIPESFEMININE HYGIENE PRODUCTS?

No! The presence of this problem is one of the most prevalent we see in tanks. Wipes and/or feminine hygiene items block sewer pipes and do not decompose properly in the holding tank, causing backups.

how often can i do laundry?

It is critical not to overburden your computer system. Instead of completing a large number of loads in a single day, try to spread them out over the course of a week. Doing no more than two loads of laundry every day – one in the morning and one in the evening – is advised.

Can I have a water softener system with a septic system?

It is unlikely that a water softener will cause damage to most septic systems, albeit they may necessitate the installation of a somewhat bigger tank disposal area.

Can We Drive Over Our Leach Field?

Neither driving on the leach field nor on the entrance and exit sewer pipes, nor on the septic tank, is suggested by the manufacturer. It is possible to restrict or slow down efficient evaporation by compacting the soil over the leach lines. Evaporation is a critical component of the drainage and disposal process. It is possible to induce settling and even rupture of sewage pipes by driving over them. It is possible to produce cracks in a tank by driving over it, especially if it is made of fiberglass or plastic.

do i have a septic systeM?

Do you utilize well water in your home? Is there no meter on the water main that leads into your home? Do your water bill or property tax bill display a “$0.00 Sewer Amount Charged” or “$0.00 Sewer Amount Charged”? What about your next-door neighbors? Do they have a septic system? Your home may have a septic system if any of the following questions were answered affirmatively:

How do I find my septic system?

Once you’ve confirmed that you have a septic system, you may identify it by looking at your home’s “as built” drawing, inspecting your yard for lids and manhole covers, or calling us for assistance.

How Far Does The Tank Have To Be Away From The House?

The normal setback distance from the home is 10 feet. Yavapai County is committed to upholding this obligation. Keep these setbacks as they are to allow for easier access and to avoid any potential foundation and moisture concerns.

An alarm is going off in my tank- what do I do?!

The sirens on certain alternative systems alert the homeowner to a possible problem prior to effluent or waste backing up into the house. The alarm may sound to warn a problem with the electrical system or a high quantity of liquid in the tank. A pump or float may be malfunctioning, in which case it is recommended to contact either JT’s or your alternate system maintenance provider for assistance as soon as possible.

Can I Plant A Tree Over My Leach Field?

No.

Root invasion from trees is one of the most prevalent problems that affect septic systems today. Certain species of trees are extremely harmful to your septic system and should be avoided at all costs. Please check your local nursery for further information.

why do you suggest running a sewer camera down my line?

A difficult blockage may necessitate the services of more than one plumber. Pipe obstructions can be caused by a variety of factors, including tree roots, grease, aging pipes, and foreign items. Our power snakes and Ridgid sewer cameras are excellent tools for identifying problems such as the following: Pipes that are broken, cracked, corroded, or collapsed are considered damaged and must be repaired or replaced. A clog is caused by a deposit of grease or a foreign item that prevents the passage of water.

Joints that are leaking—the seals between pipes have failed, enabling liquid to leak through.
