. The outlet pipe should be approximately 3 inches below the inlet pipe.
- If the tank is a manufactured precast concrete septic tank, the top of the effluent outlet pipeline should be 10 or 12 inches below the top of the tank wall. Typically, the tank outlet is on the opposite wall from the tank inlet.
How do you unclog a septic tank outlet?
If you believe that the clog is in the pipe instead of the septic tank, you may be able to fix it on your own. Sprinkle the drain with baking soda, then dump vinegar into the pipe. Leave the mixture to sit in the pipe for an hour or two. Finally, flush the drain with hot water.
What is outlet in septic tank?
The septic tank outlet tee blocks floating scum and sewage from flowing out of the tank where it would rapidly clog the drain field and effluent piping.
Where is the outlet baffle in septic tank?
Septic baffles are located at the junctions where pipes enter and exit the tank. The one at the inlet pipe is called the inlet baffle, and the one at the outlet is called the outlet baffle.
What is the function of inlet and outlet pipe of a septic tank?
The inlet pipe is used to transport the water waste from the house and collect it in the septic tank. It is kept here long enough so that the solid and liquid waste is separated from each other. The second pipe is the outlet pipe. It can also call the drain field.
What are the signs that your septic tank is full?
Here are some of the most common warning signs that you have a full septic tank:
- Your Drains Are Taking Forever.
- Standing Water Over Your Septic Tank.
- Bad Smells Coming From Your Yard.
- You Hear Gurgling Water.
- You Have A Sewage Backup.
- How often should you empty your septic tank?
Where is a septic tank filter located?
Most septic tank filters are located inside of the baffle of the tank. For this reason the filters are very important, since they help regulate the flow to the area of drainage. The septic tank filters are very important in situations where waste is actually being delivered from the septic tank to the drainage area.
What is a septic outlet baffle?
The outlet baffle directs the flow of effluent from the tank to the drainfield; it prevents the scum layer from exiting straight into the outlet pipe and causing drainfield clogs and premature system failure.
Do all septic tanks have baffles?
Every septic tank contains two baffles, one at the inlet and one at the outlet.
Does a septic tank need an inlet baffle?
Inlet baffles are needed for proper performance of the septic tank. Raw sewage from the residence is directed by the baffle downward into the middle zone of the septic tank. This means the effluent follows a tortuous path through the tank, which provides the necessary detention time for the larger solids to settle out.
How much lower should the outlet be than the inlet on a septic tank?
Generally speaking, the outlet on a septic tank should be around 4–6″ lower than the inlet, depending on the size of the tank. The tank itself, when set in place, should be as level as possible. The height difference from inlet to outlet is accounted for in the tank’s manufacture.
How deep should septic pipe be buried?
On average, trenches should be around 12-24 inches-deep, and wide enough to house your pipe comfortably before filling it in with soil and sod.
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.
- 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
- 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.
Septic tank outlet pipe
I have a 30-year-old house with a single chamber 1000-gallon concrete septic tank and a traditional leach field that is in need of repair. We had the tank pumped when we purchased the property in 1990, but I let it sit for 7 or 8 years before pumping it again, which resulted in the need to rebuild the leach field. Maybe it was ready to go after 20+ years, or maybe I should have pumped it sooner.whatever the case, I’m currently in the middle of a three-year pumping cycle and consider it inexpensive insurance.
- $$$$$ So I had the tank drained two weeks ago, and the septic technician determined that the water level was too high.only 2′′-3′′ below the top of the tank.
- It just so happened that I happened to be standing nearby when the excavator placed the outlet pipe.
- So I took the shovel out and dug up the pipe, cutting approximately 1.5 inches off the end.
- I’m optimistic that the level issue has been rectified, though I’ll double-check it before burying the cleanout cover in the ground.
- I’ve seen from reading previous posts that one approach is to connect the pipe with a ‘T’ at the other end.
- 8.5 inches in from the outside of the tank is where the baffle is located (BTW, I’ve already filled the 3′ deep hole surrounding the pipe).
- If we assume that there is just enough area for a ‘T,’ the only way to install it that I can see is through an inspection port.assuming that there is one.
- Is it possible, however, that there is a 6′′ inspection hole that I may use to go through?
- Should I simply accept the situation as it is and allow the baffle to do its job?
Where is Septic Tank Outlet?
|Author:Septic Tank Yank (CO)ruraldiy,We have a plugged up septic tank and want to put in a cleanout for the pipe to the field from the septic tank.If your septic tank is “plugged up”, installing a cleanout in the effluent pipeline will not solve your problem.The solution to a “plugged up” septic tank is to have the contents of the tank removed by a septic tank pumper.How deep from the top would I expect to find the output drain?If the tank is a manufactured precast concrete septic tank, the top of the effluent outlet pipeline should be 10 or 12 inches below the top of the tank wall.Typically, the tank outlet is on the opposite wall from the tank inlet.Before you install a cleanout in the effluent pipeline, think about how effective this cleanout will be in solving the problem causing the failure of your septic system.In my view there is no need for a cleanout in the effluent pipeline.If the leach field is totally clogged, cleaning the distribution pipes in the leach field will not cause the leach field to perform properly again.My advice to you is to consider modifying your system to the standards that are defined in the following response to an inquiry posted on the Plbg.com Discussion Forum by a fellow self-named “Dumbdad”.Author: Septic Tank YankDumbdad, sure sounds to me like the septic man is right. If you decide to have the leach field replaced, consider installing 2-half sized leach fields equipped with a 4-inch, NDS brand diversion valve. Cover the valve riser with a 10-inch round irrigation valve box to allow for easy access. The top of the box is set at the final grade elevation. The valve will allow the alternation of flow to the fields. Use half the field for 1-year while the other half rests. Turn the valve annually on the 4th of July, SEWAGE INDEPENDENCE DAY. Celebrate your independence of the sewer grid, and remember that with this independence comes the responsibility of a sewage treatment system operator.I recommend the use of plastic leach field chambers such as the ADS Bio-Diffuser, or Infiltrator brand. Cover each chamber leach field with a 4-foot wide sheet of geotextile fabric (landscaping fabric). The geotextile will prevent the migration of silt into the void under the chambers. The fabric also acts as a wick, wicking by capillary attraction, the effluent up over the chamber units and then into the soil.Install 4-inch monitoring and ventilation ports to the ground surface on each end of each field. The 4-PVC risers are covered with plastic 6-inch round irrigation valve boxes. The tops of the irrigation valve boxes are set at the final grade elevation. The boxes will allow easy location, easy access, and you can run the lawn mower right over them. Typically the covers of the boxes are green.The tops of the in-use field monitoring ports are fitted with 4-inch female threaded adapters, and threaded plugs to prevent sewer gas odors from emanating into the yard. The tops of the resting field ventilation ports are fitted with a 4-inch female adapters, and plastic drain grates.The ventilation ports will allow atmospheric oxygen to enter the leach field, and this will create an aerobic condition in the resting leach field. The oxygen will oxidize the Ferric sulfide (that black slimy crap), a major component of the clogging mat. Also, the aerobic condition will allow the aerobic microbes, present in the surrounding soil, to migrate to the clogging mat and consume the organic matter constituent of the clogging mat, and consume the dead bodies of all their anaerobic microbial cousins. Exchange the solid threaded plugs with the drain grates when the valve is turned on SEWAGE INDEPENDENCE DAY.While you are involved with the major renovation of your septic system, I recommend that 20-inch plastic risers be installed over the inlet manhole, and the outlet manhole of the septic tank. The covers of the risers should be at the final grade elevation to allow easy access to the tank. Let’s face it, if you must excavate the soil over the septic tank manhole with a shovel, chances are that this chore will be avoided. I use Tuf-Tite brand risers.I also recommend that the outlet tee of the tank be fitted with a septic tank effluent filter. The brand that I use is manufactured by SIM/TECH (the big bottlebrush type), although there are several other high quality filters on the market.The filter will reduce the organic matter in the effluent from flowing into the leach field. Clean the filter annually on SEWAGE INDEPENDENCE DAY.Another chore that should be performed annually is the measurement of the sludge accumulation in the primary chamber of the septic tank. The sludge can be measured with a “SLUDGE JUDGE.” Do an Internet search to obtain this neat device. I recommend the implementation of the “1/3 RULE” of sludge removal. When the level of the sludge is 1/3 the total liquid depth of the septic tank, it is time to remove it.The final chore to be performed on SEWAGE INDEPENDENCE DAY is to record all of the maintenance performed on the system in a maintenance log. I prepare a SEWERS CAN BE BEAUTIFUL operation manual for each of the septic systems that I install for my clients. The manual contains a description of the system design, photos of the system components, an as-built plan, a description of the required maintenance procedures, a copy of the permit, and the maintenance log. The manual becomes an excellent sales tool when the time comes to sell the home. The manual answers all questions a potential buyer may have regarding the performance of the septic system, and will allay the fears typically encountered when purchasing a home served by a septic system.Well Dumbdad, I had better end this lengthy diatribe. If all soil absorption type septic systems were designed and constructed to the above standards, then there would be far fewer failed septic systems. Maintenance is the key to successful septic systems. However, if the required maintenance is difficult, or impossible, then chances are it will not be performed. If you would like photos of my typical standard system, send me your e-mail address. My address [email protected] Aldrich (Septic Tank Yank)Septic System ConsultantTimnath, Colorado|
Septic Systems Explained
Explaining Septic Systemspci admin2018-11-30T00:00:00 11:38:06-08:00 It is the title of a popular newsletter published by the University of Minnesota Extension Service entitled “Get to Know Your Septic Tank.” Unfortunately, a large number of homeowners are unaware of their septic tank. Once buried, the tank and its associated components are mostly forgotten until sewage accumulates to the level of ankles in the basement or bursts up in the yard. After that, another septic tank system is wrongly condemned for failing to perform its function properly.
- How many people would never clean the ashes out of a wood stove or fireplace if they had to?
- However, when a sewage system fails due to a lack of sufficient maintenance, the responsibility is sometimes placed wrongly on the “bad” septic tank in question.
- The tank is filled with raw sewage that has been collected from the home sewer.
- The liquid that comes out of the septic tank is referred to as effluent.
- Bacteria that do not require oxygen from the surrounding air flourish in the tank environment.
- As a result, the term “septic” has been used to describe this tank.
- However, because the volume is never decreased to zero, a residue is always left behind.
The home sewer is responsible for transporting sewage to the septic tank.
In eight feet, a grade ranging from one to two inches is applied.
In a hundred feet of pipe, a one-percent slope corresponds to a one-foot drop.
In colder regions, these low points are the locations where sewer pipes freeze, leading to backups.
The interior of the home sewer pipe should be smooth to prevent sewage from catching and causing a clog to develop.
It’s possible that a partially clogged house sewage pipe is causing the problem if the homeowner discovers that the toilet isn’t flushing as quickly as it used to or that the floor drain is backing up when the clothes washer discharges.
The intake line to the septic tank is converted from the house sewer.
As soon as the sewage enters the tank, it begins to drop into the liquid in the tank, resulting in a downward flow.
The majority of states need an entrance device, which can be either a baffle or a sanitary tee.
The installation of inlet devices is not required in certain jurisdictions, and many devices are damaged or destroyed when a clogged pipe is illegally opened with a plumbing snake in the home’s main sewer line.
The bottom of the input baffle or sanitary tee should protrude below the surface of the liquid for at least six inches and not more than 20 percent of the total tank liquid depth, depending on the application.
As an example, in a tank with 60 inches of liquid, the baffle or tee should reach at least 6 inches below the surface of the liquid but not more than 20% of 60, or no more than 12 inches below the surface of the liquid.
Unless the baffle or the tee is installed sufficiently deep, the downward flow may generate agitation in the tank, resulting in an increase in the amount of solids transported out with the effluent.
The floating scum layer is located at the very top of the water column and accumulates wastes such as soap or detergent scum, cooking grease, cigarette filters, and any other item that floats in the water.
This layer, which may be found at the bottom of any tank, is formed of disintegrating and partially decomposed organic matter which has sunk to the bottom of the tank.
Some solids are unable to decide whether they should sink or float, and as a result, they may linger in the clear zone between the scum and sludge layers until they are taken out through the exit baffle and pipe.
It is not recommended to flush inorganic objects down the toilet such as plastic film, condoms, and other similar items since they can cause major blockage difficulties in a septic tank.
It is critical that the tank have a large amount of clear space.
The pace at which liquid flows through the tank increases as a result, and some of the solids begin to be carried out of the tank by the liquid.
When the bottom of the scum layer comes too close to the bottom of the outlet device, or when the top of the sludge layer gets too close to the bottom of the outlet device, the tank has to be cleaned.
The type of bacteria in the tank is determined by the type of sewage that flows into the container.
There are no two septic tanks that are precisely same.
Because the amount of water used varies, the amount of sewage diluted varies as well, and vice versa.
Tank temperatures vary based on the kind of water used, the depth to which the tank is submerged, the amount of tank insulation, and other factors.
Bacteria, on the other hand, are constantly present in sewage.
The bacterial action in the septic tank begins on its own and continues for as long as particles are deposited in the tank.
When submerged in liquid, the bottom of this device shall extend into the liquid for a distance equivalent to 40 percent of the depth of the liquid.
If there is no outlet device, or if it comes off or is removed, the scum layer will flow out of the tank and into the soil treatment unit, clogging the soil pores and causing the tank to overflow.
A local business may provide such an examination as part of a service contract.
The effluent from a septic tank is often murky and contains suspended materials as well as germs (disease-causing bacteria and viruses).
A half cup of effluent is expected to contain a million or more bacteria and at least as many viruses as a teaspoon of water.
These are the solids that won’t settle out and are responsible for the hazy appearance.
In the soil treatment system, this type of treatment is carried out.
The usage of cold water detergents has resulted in a reduction in the temperature of septic tanks.
Many septic tank installers in Minnesota are insulating the tops and sides of their tanks with several inches of expanded polystyrene to keep the tanks warm in the winter.
When living in a northern climate, it is necessary to remove solids from septic tanks more frequently than when living in a southern climate.
The use of two tanks in series is advantageous.
As a result, if there were a second tank, the flow into it would be significantly slower, and the outflow would be even slower.
A number of local rules in Washington now mandate that two septic tanks must be utilized in the construction of a building.
The trickling flow from the septic tank appears to create an encrustation or corrosion of the pipe leading to the septic tank.
It is necessary to use Schedule 40 or 3034 plastic pipe and to provide appropriate support between the septic tank and the edge of the excavation in order to prevent drooping at this location.
Inspection hatches should be put above the equipment that supply and drain water.
It is also possible to determine the amount of sludge present at the bottom of the tank by inspecting the inspection pipe that is located above the outlet device.
In order to evaluate the amount of scum in a septic tank, it is essential to enter the tank prior to the inspection pipe at the tank outflow.
The discharges from water softeners are frequently held responsible for septic tank malfunctions.
A slight saline solution is beneficial for the growth of bacteria.
A surplus of salt, on the other hand, will be detrimental to bacterial growth.
If the resin beads are not maintained clean, the effectiveness of the softener will decrease as the softener becomes older and, in particular, if there is iron in the water.
As the beads become more and more clogged, the frequency between softener recharges must be increased in order to maintain soft water, resulting in an increase in the amount of salt that is wasted.
As a result, homes that have water treatment systems may choose to route water softener waste to a drywell that has been specifically designed for this purpose.
When a softener is added to a system that is barely large enough to handle the daily sewage flows, it is possible that back-ups occur.
The softener is being held responsible for the sewage system malfunction.
Back-ups and surfacing will occur when there is more liquid flowing into the system than the system can handle.
Modern high-density polyethylene tanks and concrete tanks are the most often used types of storage containers.
The septic tank, tank lid, and manhole extensions must all be watertight in order to prevent ground water from leaking out or into the system.
When the storage tank is completely full, it must be cleaned and emptied out.
Long underground perforated pipes or tiles connected to a septic tank constitute the drainage field in most cases, but not always.
On a sloped property, pipes are laid across the slope line to prevent all of the effluent from simply pouring down the slope and bursting through the drain line pipe.
It is the soil underneath the drain-field that is responsible for the ultimate treatment of septic tank effluent.
The estimated daily wastewater flow and soil conditions determine the size and type of drainage field to be constructed.
The maximum length of a trench is normally around 150 feet, however this might vary depending on the conditions. a link to the page’s load
How to Connect Pipes to a Septic Tank
Septic tanks are connected to dwellings by four-inch pipes. Image courtesy of dit26978/iStock/Getty Images. Most contemporary septic tanks, whether constructed of concrete or plastic, are divided into two compartments by an internal baffle and equipped with an intake and output port. In most cases, when you first install the tank, each port has a preinstalled 4-inch sanitary tee fitting. You connect the waste line from the building to the inlet fitting and the drain line to the outlet fitting either by gluing it or by using a mechanical flexible coupling to connect the two lines (often referred to as aFernco coupling).
- Septic tanks used to have only one chamber in the olden days.
- The scum layer contains greases, oils, and other lighter-than-water contaminants that could clog the soil.
- Whatever your feelings about the necessity of the tees, they serve as an insurance policy against the failure of the septic tank baffles, and it is smart to have them installed.
- In order to keep debris out of the pipes, some plumbers put grates on the top portions of tees.
How to Install Septic Tees
The installation of the tees on the septic tank must be done from the inside of the tank if the tees do not come with the tank. A 4-inch tee is normally firmly secured by predrilled or, in the case of concrete tanks, preformed holes in the tank’s inlet and outflow holes. A bead of butyl or silicone caulk around the perimeter of the tee on both sides of the tank will enough in most cases, but it’s not a terrible idea to apply some in case you do need glue. The top of the tee should have a short piece of tubing attached to it to allow the aperture to extend over the scum layer in the tank, while the bottom of the tee must extend below the scum layer, or around 2 feet below the tee, to allow for proper drainage.
Connecting Inlet and Outlet Pipes
The waste and drain pumps are located in trenches that slope toward and away from the tank, respectively, with a slope ranging between 2 and 10 percent. For a modest slope, it’s fine to glue the pipes straight to the tee; but, if the slope is steep, you need glue a 22 1/2-degree bend onto the tee to make the glue connection completely waterproof. If necessary, the bend can be configured such that it faces upward on the input side and downward on the outflow side. Despite the fact that the pipes fit firmly in the fittings, it is necessary to glue them together.
If you don’t, the tee may become disconnected and fall into the tank, necessitating the need of expert services to repair. A septic tank may be deadly, and falling into one or even peering into one too closely can be fatal. Never attempt to do this repair yourself.
Tank Troubleshooting: Checking Inlet and Outlet Baffles
Receive articles, stories, and videos about septic tanks delivered directly to your email! Now is the time to sign up. Septic Tanks and More Receive Notifications When inspecting the septic tank, it is important to look at both the inlet and outflow baffles, as well as the location and manner in which the piping enters and exits the tank. In order to allow for the settling of solids in the tank and to avoid the “short-circuiting” of water and solids through the tank, inlet baffles must be installed to guide the flow into the tank downward.
- Solids, on the other hand, can often block the effluent screen if the input baffle is not in place or not performing as it should, resulting in either sewage backing up into the home or, preferable, an alarm signaling that the screen needs to be cleaned.
- Fixing the baffle and making sure it has the right submergence based on the depth of the tank is preferable in the long run for you and the homeowner.
- A lot of times, this happens when the pipe is not adequately bedded in the location where it spans between the excavation wall and the tank, which is a common occurrence.
- As a result, if it results in a partial blockage, it becomes a site where freezing difficulties may occur during the winter months.
- This might result in severe corrosion around the outlet baffle, which may need the replacement of the baffle.
- The sewage pipe is pushed too deep into the tank in concrete tanks with cast baffles, resulting in insufficient room between the pipe and the baffle wall, which is an issue in concrete tanks with cast baffles.
- It is possible that if a sanitary tee is used as a baffle and the pipe moves enough, the baffle itself will be cocked at an angle as a result of the interference.
- If there is an effluent screen in place, the problem is generally discovered before a significant amount of solids has been transported to the soil treatment and dispersal region.
- It is necessary to reseat the piping at the right slope, as well as straighten or replace the exit baffle, just as it was with the entrance pipe.

5 Signs Your Septic Drainfield Has Stopped Working
Unlike municipal septic systems, which consist just of a subterranean tank that collects waste and water, residential septic systems are more complex. Water finally departs the tank through an outlet pipe and into a network of long perforated pipes known as the leech or drainfield after reaching the tank’s interior. The drainfield is equally as vital as, if not more so than, the septic tank in terms of wastewater treatment. In the event that this component of the system begins to fail, prompt action might mean the difference between relatively small repairs and a total drainfield replacement.
- Drainage is being slowed.
- As long as there is still any water in the pipes of the field, the drains in your home will continue to function, albeit at a slower rate.
- The presence of obstructions in the inlet or outlet pipe, as well as several other septic problems that are less difficult to resolve than drainfield problems, might result in delayed drainage.
- You may detect puddles or spongy and mushy ground all over the place if you look closely.
- A backup occurs when the water level rises to a level that forces sewage up the input pipe and into the lowest drains in your house, which is known as a back up in the system.
When the drainfield leaks quicker than typical or contains decaying waste within that is meant to stay in the tank, you will see the effects on the surface.
Returning Flow is the fourth step.
If you presume that the tank just need pumping, the service technician may discover water and sewage entering the tank from the outlet in a reverse flow, which would indicate that the tank requires more than pumping.
The presence of reverse flow from the drainfield is an obvious indication that you want jetting or pipe replacement services.
The Development of Odors In the end, you can utilize your sense of smell to detect indicators of drainfield issue.
Any sewage or toilet scents, even if they are weak and difficult to detect, signal that you should have a professional evaluate your home immediately.
This is the most effective way.
Whenever we observe a decrease in drainage capacity, we will inform you of the problem and your choices for resolving it before the system stops processing waste altogether.
In addition, we’re pleased to address any of your questions or concerns concerning your drainfield or septic system in general with a professional response.
COMMON PROBLEMS — JT’s SEPTIC
You should examine the sewer cleanout on the exterior of the home if you are hearing gurgling and all of the house fixtures are clogged. This is often a black 3-4 in color “inch ABS pipe with a threaded cap is available. Remove the cap (WARNING: BE CAREFUL! (WARNING: IT MAY CONTAIN SOME PRESSURE!) : Assuming the sewage line is completely dry, you will have a clog inside the home plumbing, directly in front of the cleanout valve. Make a phone call to a plumber and have them rooter the line. Sewer line cameras are available from several rooter/plumbing businesses.
- You have two options at this point: call your preferred septic provider or pull up the tank lids yourself and check the water level and solids content in the tank yourself.
- Most tanks erected after January 2001 include a filter that has to be cleaned at least once a year (we clean filters—please call us).
- We’ll even notify you once a year when it’s time to clean your filters!).
- It’s likely that you have a blockage in your sewage system.
Whenever you flush the toilet, the water gurgles, the toilet takes an unusually long time to flush, or the water in the shower turns brownish after you have done the laundry, you are receiving a subtle indication that trouble is brewing. In order to determine when the tank was last pumped, look through your records and then contact your preferred septic provider for assistance.
If you are experiencing unpleasant odors within your home, such as rotten eggs, it is likely that a trap or vent inside your home is not venting correctly. Call your plumber right away since these gases are harmful to both people and animals!
ODORS OUTSIDE IN THE YARD
At times, the smells emanating from the roof vents will seep into the yard due to meteorological conditions. Make use of a plumber to elevate the roof vents and/or to place a charcoal filter in the vents, as needed. It’s important to remember that your septic tank is vented via the roof.
SURFACING IN THE YARD
If you notice effluent appearing in your yard, contact your septic service provider immediately. If you see this, it indicates that your leach line has failed and you should get help right away.
HEAVY SOLIDS- OVERDUE FOR PUMPING
Contrary to common perception, you DO need to have your septic tank pumped on a regular basis. Pumping maintenance should be performed on a regular basis, otherwise your system will get overwhelmed with solid waste and eventually cause damage to your leach lines.
DON’T MAKE THIS HAPPEN TO YOU! This is an extreme example of a tank that is overflowing. There is sewage flowing from the tank access holes and into the yard!
grease build up in sewer pipes
Fats and grease should never be flushed down the toilet or sink. They have the potential to harden the lines and cause failure; they have the potential to generate an excessive buildup of the floating scum layer in the septic tank; and they have the potential to go into the disposal regions and adjacent soils and completely block the system off. A shattered lid can pose a serious threat to both animals and children. It is conceivable that they will fall through the cracked or broken lids and will not be noticed until it is too late to save themselves.
crushed or settled pipe
This is the second most prevalent problem we notice in septic systems that are less than 10 years old. In addition to blocking flow, loose fill soil surrounding the tank is causing a backup into the house since it is pulling the pipe with it as it settles. We have even observed instances when contractors installing new systems do not correctly pack the fill earth below the pipe, resulting in pipe settlement on systems that have not been utilized or have only been used for a short length of time (see below for an example).
SEWER OUTLET PROGRESSION
When it comes to modern septic systems, this is the most typical issue we encounter. Take note of the fact that the unsupported outlet pipe is being driven down by settling dirt. Watch as the water level in the tank rises, forcing the flow of water in the inflow sewage line to slow. This will eventually result in a clog in the inflow sewer line at some point. The solids flowing down from the house will not be able to enter the tank correctly because of the high water level.

settled inlet sewer pipe on unused system:
Even if the septic system has not been utilized in some time, it is conceivable that problems will be discovered during the inspection process. Pipes might settle on unoccupied ground and in yards as a result of faulty installation and/or automobiles and/or ATVs running over the pipes without realizing they are there. It may be beneficial to all parties to have a skilled inspector take a look at the system and diagnose any concerns, even though the County does not require an examination on an underused system before transferring ownership.
Roots growing in and around the septic tank:
In addition to disrupting the system by clogging or destroying drainage and distribution lines, tree roots can also enter the tank, causing it to leak. Foul odors, poor drainage, and patches of vegetation in the leach field are just a few of the signs that you may have a root problem.
Branches and roots may wreak havoc on the system, clogging or even damaging drainage and distribution lines, and they can even penetrate the tank in some cases.
Foul odors, poor drainage, and patches of greenery in the leach field are just a few of the signs that your root system is failing.
orangeburg sewer pipes
Orangeburg pipe was made in Orangeburg, New York, from 1860 to 1970, and was utilized to plumb numerous septic and wastewater systems throughout Yavapai County during that time period. Orangeburg pipe is produced from rolled tar paper (wood pulp that has been sealed with hot pitch) and was considered a low-cost alternative to metal, particularly after World War II, because of its flexibility and durability. In fact, the pipe itself is so soft that professionals might cut it with a knife during the installation process!
Orangeburg, on the other hand, is known for degrading over time (it has a 50-year lifespan at the most) and deforming when subjected to pressure.
If the septic system is approved, Orangeburg will normally be stated on the permits as the material for the inlet and/or outflow pipe material, respectively.

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.
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.
- We’ve taken those findings and included them into Minnesota’s septic tank requirements.
- Septic tanks should be built such that their length is two to three times longer than their breadth.
- The liquid depth of the septic tank, denoted by the letter D, serves as the foundation for all other tank parameters.
- The top of these baffles must not be closer than 1 inch to the tank cover in order to function properly.
- 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.
The outlet baffle should be installed so that it extends into the liquid of the septic tank to a depth of 0.4D. Septic tank study looked at the placement of the bottom of the outlet baffle to establish the depth at which the cleanest effluent may be released, and the results were published in the journal Septic Tank Research. Since the introduction of outlet filters, it is possible that this dimension is no longer as important. When the bottom of the scum layer is estimated to be 3 inches or closer to the bottom of the exit baffle, the septic tank should be cleaned.
I’ll use a septic tank with a liquid depth of 60 inches to demonstrate the various measurements.
The input baffle should protrude 12 inches above the liquid level in the tank to provide proper ventilation.
According to the elevation of the invert of the outlet pipe, the outlet baffle should be 24 inches deep in the liquid and 12 inches above it, with the baffle extending 24 inches into and 12 inches above the liquid level.
In your report, you said that the scum layer was heaviest at the intake end of the septic tanks that you had examined.
In addition, your intake baffle extends more into the liquid depth than the study indicates it should.
It is not necessary to be concerned about scum building near the septic tank’s intake if the effluent quality is good.
It is necessary to be concerned about scum building near the bottom of the outflow baffle because particles are being released with the effluent.
As we all know, the effluent quality of an onsite sewage treatment system is a major problem when it comes to the proper functioning of the system.
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.’
