Why Do You Need A Vent In Septic Tank? (Correct answer)

The bacteria active in a septic tank are anaerobic. Anaerobic means the bacteria operate without oxygen from the air. There is not a great deal of gas generated in a septic tank, but the gas must be released so pressure does not build up in the tank. If the septic tank has inlet and outlet baffles, they must be vented.

  • Yes, every septic system needs a vent pipe. The vent allows septic gases to exit the system, so it is not allowed to build up and cause an explosion. As the tank is filling up with waste, it is generating malodorous gases, better known as septic gases.

Where do you vent a septic tank?

As the septic tank fills with waste and water, the air has to go somewhere or the pressure will stop the flow and back up into the structure. To solve this problem a vent is connected to the top of the tank to release the waste gases and air outside.

Should a septic tank be airtight?

Septic tanks need to be watertight. The riser should be sealed to the top of the tank and the riser cover should be sealed to the riser with butyl rubber or some other flexible sealant. No liquid should enter or leave the tank.

Do septic tanks need air?

A Septic Tank’s Vent The tank and its plumbing system are sealed, which means the air inside is trapped. However, as the tank fills with waste and water run-off, the air needs somewhere to go – otherwise, the pressure it creates will halt the flow of waste and back up the toilets, etc.

Does a leach field need a vent?

Leach field venting is required to remove noxious gases and allow for higher-rate digestion of pollutants. Inadequate ventilation can result in decreased digestion of pollutants and plugging of the leach field.

Can I cut my septic vent pipe in yard?

They shouldn’t be removed but they can be cut down, level with the ground. Other white pipes may be standing above your septic tank, pump tank or close to your foundation. Those are available for maintenance, if needed, and shouldn’t be removed. Again, they can all be cut down close to the ground surface and recapped.

Should I bury my septic tank lid?

A septic tank stores the solids from drains and needs to be pumped out about every two years, so it’s not a good idea to cover the area — you need to always be sure where to find the tank. Modern septic systems have an 8-inch plastic pipe that rises from the tank to a few inches above grade.

Can a septic tank never be pumped?

What Are the Consequences of Not Pumping Your Tank? If the tank is not pumped, the solids will build up in the tank and the holding capacity of the tank will be diminished. Eventually, the solids will reach the pipe that feeds into the drain field, causing a clog. Waste water backing up into the house.

How far away can vent be from toilet?

According to the UPC, the distance between your trap and the vent should be no more than 6 feet. In other words, for the vent to work properly, it needs to feed into the drain line within 6 feet of the trapways that connect to it.

Why do some leach fields have vent pipes?

The purpose of the ventilation pipe is to provide oxygen to the drain field where the aerobic bacteria live. Air enters through the roof vents of the home’s plumbing and exits through the lower vent in the field.

How do I hide my septic vent?

Several options exist for covering the vent pipes, such as functional birdbaths, fake rocks and Roman columns. Some manufacturers make birdbaths with a pedestal to fit over the vent pipe. Some come with odor-controlling filters, and can be set to a specific height.

Why does my septic vent smell?

Septic odors are caused by gases in the system, including carbon dioxide, hydrogen sulfide, and methane. Not only can they be annoying, a high enough concentration of these gases can be toxic, or even explosive.

Amazon is a good illustration of this. Even while septic tanks and systems aren’t extremely difficult, they can exist in a variety of designs, which means that individuals frequently have questions about what components their septic system should have in place. Due to the fact that this was one of the questions I had while studying my new septic system, we will spend the most of today discussing septic tank vents.

The answer is yes, your septic system, as well as all sewage systems for that matter, require a venting system in order to allow gases to exit the system and avoid harmful buildups or the formation of airlocks.

Follow the links in this page to learn more about the importance of septic system ventilation and the various methods in which a properly constructed and running system will vent-out gasses.

How a Septic System is Vented?

So we’ve previously established that all sewage systems require ventilation in order to allow gasses to escape when necessary. The specifics of what it looks like on a regular septic system have not been investigated. There are various options for venting your septic system. Here are the details:

Venting Method1: Inlet and Outlet Pipe Ventilation

The inlet and outlet pipelines are the initial points of contact between your septic system and the outside world. Flowing waste from your home into the septic tank is made possible by the input pipe, and flowing waste from the tank to the drainage field is made possible by the outflow pipe. When these pipelines are free of obstructions, gases should be able to flow out into the drainage field.

Venting Method2: The Vent Pipe in Your Roof

Have you ever pondered what those vent pipes coming out of your roof were supposed to be used for before? That is exactly what I thought they were, in fact, I believed they were some sort of vent from the bathroom fan, but it turns out that those venting pipes coming out of the roof are meant to draw the smells and gases produced by your septic system away from your home. Here’s a nice short movie that illustrates why it’s vital to have plumbing vent pipes on your roof in the first place.

Venting Method3: Yard-Based Septic Vent Pipe

The yard-based septic vent is typically comprised of a capped piece of white PVC installed above the leach field to provide ventilation. A pipe in the shape of a candy cane could also be seen in your yard. When used in conjunction with the roof vent pipe, this pipe serves the goal of allowing the air pressure in the drain to be brought back into balance. When water displaces air in the vent pipes, the system must be brought back into balance.

What is a Septic Tank Vent For?

Finally, your sewer or septic system vent pipes are responsible for the equalization of air pressure in the system as well as the safe evacuation of septic gases from the system. Both septic systems and sewer systems produce gases as a typical result of the microorganisms that break down the waste that is disposed of in them.

These gases often have a horrible stench, similar to that of rotten eggs. As the gasses leave via the vents, they are transported away from your home or yard by the air currents.

Why Does My Septic Vent Smell?

The bacteria in a septic tank are anaerobic, which means that they do not require oxygen from the surrounding air to function. The outcome of anaerobic activity is the production of smells, which are most typically caused by the release of hydrogen sulfide gas. This has the potential to produce a rotten egg smell. Sometimes the smell will only occur on rare occasions; in this situation, it is possible that the scent is caused by a specific wind current blowing air from roof vents, rather than a plumbing problem.

The presence of a foul smell, on the other hand, can indicate the presence of a blockage or other problem with your septic system.

How do I stop my septic tank Vent from Smelling?

If the odor is caused by a downdraft from your roof vent, a simple remedy may be to extend the plumbing vent high above the roof line, which will help to eliminate the problem. Consequently, a downdraft will have difficulty pushing the gas down towards the ground since the gas will be able to escape at a greater distance from the roofline. It is possible to avoid a downdraft caused by surrounding trees by chopping the trees, but this is a time-consuming and expensive process. A charcoal filter installed at the top of the vent has shown to be effective for others.

Other Vent Related Questions:

It’s possible that the pipes in your yard are a sewer or septic clean out. It makes it simple to check on the system in the event of a malfunctioning component. Listed below is a little video that illustrates what one of these vent pipes in your yard can be like.

What is the right septic tank vent pipe height?

Most often, the height of your rooftop vent pipe is governed by the plumbing and construction requirements in your area. As a result, be sure to check with your local inspector to see what the correct height is for your city or municipality. Your vent should be located between 1-2 feet above the roof line in order to reduce the possibility of downdraft scents accumulating. When it comes to the inspection septic system access pipes in your yard, the city inspectors often require these pipes to be sticking out quite high in order to complete the final inspection of the septic system; however, once the inspection is complete, the pipes can usually be cut down to the ground level.

What are Signs My Septic or Sewer Vents are Clogged?

Clogged septic or sewer vents are a common plumbing problem that goes unnoticed. A clogged sewer or septic vent on your roof might lead to a variety of plumbing problems in your home. Keep in mind that these vents are critical in maintaining proper air pressure in your system. You may experience drainage problems if your plumbing system does not have sufficient air pressure to allow air to easily flow through it.

Here are some of the signs that your septic or sewer system vents might be clogged:

  • If you hear gurgling or observe water bubbling in drains, call a plumber immediately. Alternatively, you may notice gurgling sounds coming from your toilet immediately after flushing. Gushing can be produced by substances that are leaking via the drain. The air should be flowing up and out of the sewer/septic vents at a constant rate. However, if the drains are clogged, the water has nowhere to go and must ascend through the drains. Sluggish Drains: A single slow drain typically indicates that there is a blockage in the sewage line that is being used. Alternatively, if you are seeing sluggish drains throughout the home, this might be an indicator that the septic/sewer vents have been clogged. Smelling bad aromas coming from your drains or toilet? It’s possible that you’re smelling air backing up via your drains.

What do I do if Septic Tank Vent Pipe is Blocked?

If you have only recently begun to notice the signs of a clogged septic or sewer vent pipe and your roof is covered with snow, call a plumber immediately. Usually occurs in a room with a flat ceiling. A blockage in the vent pipe caused by snow or ice might therefore be the cause of the problem. This form of obstruction can induce all of the symptoms associated with any other type of more persistent blockage.

Attempt to clear the snow from the vent pipe in the near term to see if it helps. Then, when the weather is a little better, have a plumber increase the height of your vent pipe to make it less likely that it will happen again in the future.

Debris Blockage of the Vent Pipe

To prevent leaves and debris from entering the pipe and producing a clog, your vent pipe should be slightly slanted. Otherwise, it is conceivable that debris has entered the pipe and caused a clog to occur. Make an appointment with your plumber to come out and clean the pipe; they will use a specific grabber tool for this purpose. Once this is done, have them re-angle the vent pipe to prevent it from occuring again.

Sewage Clogs of the Vent

Clogs in the sewage line can occur at the point where the vent pipe meets the sewer line on rare occasions. When goods such as wet wipes or feminine hygiene products are flushed down the toilet, they might cause these kinds of complications. It is NOT RECOMMENDED to flush this item down the toilet or down the drain. Solution: Your plumber may need to reach the blockage from the roof vent and use an auger to clear the obstruction out of the system by pushing it down through the system. Check out this video for instructions on how to clean the vent stack on your roof.

Also, I apologize for not being aware of the precise appearance of the septic vent pipes prior to today; I hope I was able to provide you with an answer to your issue.

Why Proper Ventilation is Important for Septic Systems

The importance of proper ventilation in septic systems cannot be overstated. As a result of faulty ventilation, practically every homeowner has experienced the odor of “rotten eggs,” which is related with the seeping septic gases that come from incorrect ventilation. We at NexGen Septics are ready to assist you avoid this disheartening circumstance by providing you with some ventilation recommendations.

Septic Tank Overview

The majority of septic tanks are massive concrete, steel, fiberglass, or polyethylene containers with a capacity of around 1,000 gallons. They are traditionally buried beneath the earth near a residence or business structure. A series of pipes and toilets installed in an adjacent structure are connected to this tank as well. A person who flushes a toilet sends waste via pipes and into the tank, where it settles at the bottom and decomposes as it decays. Water is diverted to a nearby water treatment facility or a drain field while this is going on.

A Septic Tank’s Vent

In its emptied state, the septic tank is little more than a massive subterranean hollow that is primarily made up of air. The tank and its plumbing system are both sealed, which means that any air caught inside the tank will remain trapped. However, when the tank fills with waste and water run-off, the air must find a way to escape; otherwise, the pressure it causes would prevent the flow of waste and cause the toilets and other fixtures in the nearby home to back up and overflow with waste. Because of this, adequate septic tank and system venting is essential.

Everything must be vented back through the home and out of the roof vents in order to keep the gases from building up. Getting rid of the scents that are frequently connected with a malfunctioning system or a lack of ventilation is important.

Ventilation Speed

Because septic tanks are entirely dependent on gravity for their operation, the frequency and speed with which air is vented is determined by how quickly the tank fills up – or, conversely, how quickly the tank dries out. However, as long as the air has a place to travel, the flowage from the structure to the tank will proceed as if by magic (absent some other form of blockage).

Odor Control

Some individuals who live or work in close proximity to a septic tank are happy to cope with periodic nasty odors as long as the system is in functioning order because the stench from the tank is not generally a continuous nuisance. However, there are just as many people who would prefer not to be exposed to the stench at any time. There are a few odor-control methods available for this group:

Increasing The Vent Pipe’s Height

Ventilation pipe: As previously said, the ventilation pipe is responsible for venting the air and gases that are produced inside the septic tank. By raising the height of this pipe, it becomes feasible to release the smells at a higher level, one that, on a windy day, would ideally result in the vented air being blown over the whole structure.

Pruning Nearby Trees

As previously said, the ventilation pipe is in charge of ventilating the air and gases from within the septic tank and removing them from the environment. Increased height of this pipe allows the release of smells to take place at a higher level, one in which the ventilated air is ideally blown across the structure during a windy day.

Charcoal Vent Filter

An economical option is to connect a charcoal vent filter to the top of the current ventilation pipe, which is a simple and effective solution. Despite the fact that it enables air and gases to flow through, charcoal filters also eliminate the stench that comes along with them. As an alternative, this vent can be connected to the home or business’s rooftop ventilation pipe, which acts as an additional secondary septic ventilation system, drawing smells up into and out of the home while staying above the roof line.

Does A Septic Tank Need A Vent Pipe? [Septic System Ventilation]

The process of installing a septic tank is not as difficult as it may appear. The process begins with the selection of an appropriate location and concludes with the covering of the septic tank with earth. It goes without saying that the installation is more involved than that, which is why the majority of individuals choose to employ a contractor to manage the process. If this is your first time constructing a septic system, you’ll need to figure out which kind is the most appropriate for your requirements and personal preferences.

You can pick between a gravity-fed treatment unit and an aerobic therapy unit. As part of the planning process, you’ll need to select how you’ll ventilate your septic system. The subject of discussion today is septic tank ventilation (septic tank ventilation).

Does a septic tank need a vent pipe?

Yes, a vent pipe is required for every septic system. It is through the vent that sewage gases are permitted to depart the system, preventing them from building up and causing an explosion. As the tank fills with waste, it emits foul-smelling gases known as septic gases, which are released as the tank fills up. These gases are exceedingly hazardous to human health. Sewage venting is a method that is used to safely ventilate septic tanks in order to reduce the possibility of septic gas accumulation.

What Is The Purpose Of A Septic System?

The treatment of wastewater by septic systems is accomplished by the construction of structures beneath the earth. These systems are used in places where there is no access to municipal sewage systems. Combined sewage is connected to the city sewer system via subterranean pipes, which transport the waste to a waste treatment plant, where it is cleansed and re-released into the surrounding environment. Underground septic tanks function in the same way as a waste treatment facility does on the surface.

This discharge of liquids (effluent) takes place into a leach field, which is also known as an effluent tank.

Keeping Your Septic Tank Well Ventilated

The installation of a septic tank with a vent or the purchase of a home with an existing system does not automatically eliminate all of your problems and worries. No, it will be your responsibility as a homeowner to ensure that the septic system is properly vented at all times. In fact, it will be in your best interests to take this step forward. This might result in not just drainage issues, but also residual sewage odors throughout your house and yard if you do not take precautions. This is something that no one wants, and this includes your neighbors as well.

Make use of the information on this page to deal with the problem as soon as possible.

Pump Septic System

In contrast to the traditional septic system, a pump system is a more modern option. The system makes use of a pump to assist in pushing the effluent through a bed of organic materials, such as sawdust and peat, as well as sand and man-made wetland habitat. In order to move liquid waste from the tank and into wetlands, the pump must operate at peak efficiency. The presence of contaminants in wastewater such as nitrogen, disease-causing microorganisms, and phosphorus causes them to be neutralized as soon as they reach wetlands.

  • These systems are extremely efficient, which is why they are becoming increasingly popular among environmentally conscious homes.

Purpose of septic vents both in the yard and also through the roof?

My house has septic venting that runs up through the roof as well as a vent in the yard for the septic system. What exactly is the purpose of the yard vent? Whether by code or otherwise, is this vent a requirement? Is there a “best practice”? Or.? A shot of the vent taken when it was first built, to demonstrate the interaction between the home outlet (on the right), trap in the center, and tank (on the left): This came up because we are considering moving it because it is in the path of a deck construction project.

  • The yard vent protrudes out of the grass around 16 feet from the house’s foundation.
  • (Please note that this is not a municipal sewer.) In the course of a job, I temporarily replaced the yard vent cover with a solid cap, resulting in no airflow, and I saw no difference in any of the house’s plumbing systems.
  • The leach field or the septic tank itself have been discussed, however my vent is neither of these options.
  • The fact that some homes have these vents and others do not is part of the motive for asking this inquiry; I want to understand the causes for the disparities between the two situations.

Odors and Septic System Vent Issues

What is causing the foul odor in my septic system? It’s a proven truth that sewage stinks. A foul odor will be familiar to anybody who has passed through the steam of a city manhole or stood downwind of a septic pumping vehicle. We all want to get away from the smell, but some septic system owners have a difficult time doing so as well. Gases from your septic system are released throughout the system. During the manufacturing process, gas is produced in the tank, piping system, distribution box, and trenches.

  1. The technique works because the low pressure in the pipe causes the gasses to rise and escape via the vent.
  2. People have discovered that merely extending their vent stack on the roof may completely alleviate the problem of unpleasant odors.
  3. Because they are unable to escape through the pipes and vent stack, the trapped gasses are now forced to seep out of the earth, causing unpleasant odors to emanate.
  4. Your yard will also smell like septage as a result of this obstruction in the direction of the gaseous emissions.
  5. Occasionally, the venting system will function well, but a down draft generated by winds blowing across the roof or a nearby row of trees will send the scents down into your yard, through a window, or into your air conditioner.

These filters have grown popular among those who have been unable to find a solution to their stinking vent problems in any other manner. More information about venting may be found here. ” alt=””> ” alt=””>

Proper Septic Tank Venting

The excavating required for the installation or removal of a septic tank, as well as its plumbing and venting, is normally accomplished with a backhoe. When a septic tank becomes overburdened with waste and liquid volume, the septic venting pipe and system enable the tank to vent gases and air out of the tank. This fundamental release system is necessary since a blockage prevents the tank from functioning properly. Because of this, the septic system backs up all the way to the toilets, which is a very unpleasant issue to deal with.

Septic Tanks

Septic tanks are simply a huge steel or concrete container that is buried beneath outside of a house or other structure to collect wastewater. The normal volume of a container of this type is around 1,000 gallons in volume. Within the neighboring structure, pipes and toilets are connected to the tank itself by a piping system. Waste is washed through the pipes, out of the building, and into the tank when it is processed by the waste system. The garbage settles to the bottom and decomposes, while the water is discharged into the municipal sewer system or a leech/drain field for further treatment.

The Role of the Vent

Large steel or concrete tanks are often installed outside of a structure, and they function in the same way as a septic system. The average volume of a container of this type is around 1,000 gallons in volume. Within the neighboring building, pipes and toilets are connected to the tank itself by a series of connections. Waste is washed through the pipes, out of the structure, and finally into the tank, when the waste system is activated by the user. The garbage settles to the bottom and decomposes, while the water is discharged into the municipal sewer system or a leech/drain field for further processing.

Speed of Venting

Because septic tanks are powered only by gravity, the quantity of air that may be vented depends on how quickly the tank fills up or dries out over the course of a year. As long as air can be forced via some sort of opening, the flow into the tank will continue as normal in the absence of any other obstruction.

Odor Control

Unfortunately, when septic tanks vent, the stench from the contents of the tank is released at the same time. Movement in the tank, depending on which direction the wind is blowing, might cause an odor to be released that can be carried back toward the building. When it comes to individuals who have septic tanks, it appears to be a lesser evil to deal with so long as the tank continues to function properly. Increased height of vent pipe above ground allows smells to be emitted at a higher level, which may cause them to fly over the structure as a result of the wind.

Do I need to vent my septic tank?

A venting system is required for your septic system, as well as any sewage systems for that matter, in order to enable gases to exit the system and avoid harmful buildups or airlocks from forming. You should have three kinds of pipe ventilation for your septic system: an inlet/outlet pipe, a roof vent, and yard-based pipe vents. The air enters through the roofvents of the home’s plumbing and departs through the lowervent in the field, according to the manufacturer. Air cannot be drawn through to feed the aerobic bacteria in the leach field unless there is a ventilation pipe at the other end of the pipe.

In some instances, a ventpipe is insufficient.

Birdbaths, artificial rocks, and columns designed expressly for installation above ventpipes are equipped with air holes to allow for proper ventilation.

As a result, where exactly is a septic tank vent located?

It is customary for this septic tank vent to be situated anywhere in the yard near the liquidtank. What is the lifespan of a drain field? a period of twenty years

Do I need to vent my septic tank? – Kitchen

Anaerobic bacteria are responsible for the activity in a septic tank. Anaerobic indicates that the bacteria do not receive oxygen from the surrounding environment. Although there is not a huge volume of gas produced in a septic tank, the gas must be evacuated in order to prevent pressure from building up in the tank. If the septic tank is equipped with baffles at the entrance and outflow, they must be vented.

How do I stop my septic tank from smelling outside?

Having odors in other areas outside your home is a problem. Install a carbon filter at the top of the plumbing vent to help decrease the smell of septic waste. The filters will need to be replaced about every 1 – 5 years in order to maintain their optimal efficacy.

Are sewer vents necessary?

Hazardous sewage gases can build up in the plumbing system if there isn’t a vent to enable the pressure to escape. This makes it difficult for water to pass through the pipes properly. A blocked plumbing vent causes difficulties not because it won’t let air in, but because it won’t let it out, which is the more serious problem.

How far is septic tank lid from vent?

Septic tanks are required to be at least 5 feet apart from the home in all states except Alaska. The majority of them are between 10 and 25 feet distant. Whenever the probe makes contact with flat concrete, fiberglass, or polyethylene it indicates that the tank has been located.

Why do septic tanks smell in rain?

Rain frequently causes changes in atmospheric pressure, which can result in the air being heavier as a result. Consequently, the methane gases ordinarily contained in the septic tank do not pass through the vent as readily as they would otherwise. Instead, they remain low to the ground, emitting a horrible odor that is comparable to that of rotting eggs.

Do septic vent pipe filters work?

Septic vent filters are excellent alternatives for managing and removing unpleasant aromas, allowing you to enjoy your house once again as a pleasant location to spend your time.

How do you get rid of sewer smell in septic tank?

Prepare the drain by pouring a quarter cup of baking soda down it and then leaving it for about 10 minutes. After that, add one cup of vinegar to the mixture. Allow the combination to fizzle and work for a few minutes, and then finish by turning on the water and running the disposal to clean out any remaining food waste that may have accumulated throughout the process.

What happens if plumbing is not vented?

A building’s drainage system that is not properly ventilated will be unable to adequately convey wastewater and solid waste out of the building. Overflowing drains, backed-up toilets, and other plumbing troubles may result as a result of this practice.

What is a plumbing cheater vent?

A cheater vent (also known as an air admittance valve) is a vent that extends from a fixture — for example, a sink in a new powder room — and is buried in the wall to allow for better air circulation. As a result, AAVs are intended to prevent sewage gas from entering your wall cavities. In this case, it is a mechanical vent that enables essential air into the system to aid in the effective operation of drains.

Can a toilet shower and sink share a vent?

According to standard practice, you will be allowed to exhaust just two fixtures through a toilet wet vent. 1) The toilet and the sink: The toilet is vented through the sink drain.

2) The toilet and the sink: The toilet drain should be 3 inches in diameter, the sink drain 1.5 inches in diameter, the shared sink drain/toilet vent area should be 2 inches in diameter, and the vent going up should be 1.5 inches in diameter.

How do you know if your septic tank is full?

Problems with a Septic Tank System are manifested in seven ways.

  1. Sounds of a pipe gurgling. In the event that you flush the toilet or turn on the water and hear gurgling coming from the pipes, it might be an indicator that the tank is full, needs to be pumped, or has other issues. Problems with toilet flushing
  2. Slow drains

Do septic tank lids need to be buried?

1. Is it necessary to totally bury my septic tank? Yes. Septic tanks must be buried in order to function properly.

Septic Q & A

What causes a septic system to malfunction? The unfortunate reality is that your septic system may experience a malfunction at some point in the future. Some of the telling indications are as follows:

Sewage backing up into the house
Signs of back up in the drain field area
Strong odor
Gurgling noises in the pipes and drain lines/clogged or sluggish drain lines
Signs of lush green grass or wet areas in the drain field
Proper maintenance is the key to maintaining any septic system.

What can I do to ensure that my septic system is in good working order? Pump outs should be scheduled on a regular basis.

Every system needs to be pumped out on a regular basis. If not, solids will accumulate in the tankand eventually flow into the drain field and clog the system as well as the outlet baffle. If thebaffles are damaged this will enable the scum layer in the tank to escape and flow into the drainfield.
Homes with garbage disposals should be pumped out more frequently to keep the system free ofthe solids that the garbage disposal feeds into the system.
The number of people living in the home will also affect how often the system should be pumpedout.

Is it possible for you to pump out my system through the vent or observation port that protrudes from the ground? We will not remove the air from your system through the exhaust pipe. Your system will not be cleaned appropriately or fully if you use your vent pipe to clean it. It is vital to locate the lid and begin pumping from that location, if possible. It is also the normal method needed by the National Association of Women’s Teams and the other organizations we represent. Is it possible to install a garbage disposal if I already have a septic system on my property?

Garbage disposals significantly reduce the longevity of your septic system and are the source of many expensive repairs.

It has been determined through research conducted by the Penn State College of Agriculture and North Carolina State University that biological additives such as yeast or other chemical additives are not required to aid in the decomposition of solids, and that some of these products may even damage the drain-field or contaminate nearby wells.

  • When dangerous substances and chemicals are introduced into the system, the efficacy of these microorganisms might be reduced.
  • Another important step in keeping your septic system operating smoothly is to keep track of how much water you are using.
  • The size of a septic tank can vary from a 250-gallon capacity to a 1,500-gallon capacity, depending on the age of the system, thus knowing the size of your system is quite beneficial when dealing with it.
  • Other methods of conserving water are as follows:
1. Take short showers instead of baths. Install shower heads with water-saving features.A conventional shower head uses anywhere from 3-5 gallons/minA water-saving shower head uses 2-3 gallons/min
2. Some people switch to washing machines that use less water than others.Top loading washer: 35-50 gallons/loadFront loading washer: 22-25 gallons/load
3. Reduce water use each time you flush the toilet. Put a heavy device such as a brick in a plasticbag or a water-filled plastic bottle in the reservoir or install a low-flow toilet.Conventional toilet uses 4-6 gallons/flushWater saving toilet uses 1.6-3 gallons/flush
4. Only use the dishwasher or washer when they are loaded to capacity.
5. Fix leaky faucets and other plumbing fixtures quickly.
6. Faucets.Regular faucet aerator: 2.5-6 gallons/min Flow regulated aerator:.5-2.5 gallons/min
7. Don’t do all your laundry in one day – spread out your loads throughout the week.

Is it mandatory for my municipality that I get my tank cleaned out on a regular basis? Residents of the following townships in our region are currently required to have their septic systems drained every three years, according to local ordinances:

Bucks County: Doylestown Twp., Haycock Twp., Milford Twp., Upper Makefield Twp., West Rockhill Twp.
Montgomery County: Franconia Twp., Lower Frederick Twp., Lower Salford Twp.,Upper Frederick Twp., Upper Salford Twp.

Signs of Septic Trouble

Symptoms of Septic Tank Trouble niftyadmin2020-11-24T20:43:14+00:00

What are the signs of a troubled septic system?

The most evident septic system problems are the ones that are most easily identified.

  • Make a visual inspection of your septic system and basement for signs of pooled water or muddy soil. A more lush lawn in the vicinity of the sewage treatment facility
  • Drainage in the house is slow to move
  • When you flush the toilet or do the laundry, you may have a backlog in the plumbing. Water pouring up through the floor drains on the lower level of the home gurgling noises coming from the toilet or drains odors – whether they are found outside or within the residence

Most of these issues become apparent when you are using a lot of water, such as while doing laundry. Because of this, it is critical that you spread out your washing loads and conserve water! A few simple measures such as taking shorter showers, never letting water run down the drain while washing dishes, only washing full loads (or raising the water level for a small load), and never doing back-to-back loads of laundry can all contribute to water conservation and a reduction in the amount of wastewater entering the system.

There are a number of different sources of water that enter the system.

Why are there odors inside and outside of the house?

The most common source of odor inside a home is a clogged drain. Each and every drain in your home is equipped with a trap of some sort. The trap is the U-shaped pipe that you can see under your kitchen sink when you turn it on. In order to prevent gases from your septic system from returning to your home, you must install this pipe. The trap works because water collects in that U-shaped portion of pipe, preventing the gases from being released back into the atmosphere through the drain. If, on the other hand, the water in that trap should ever run out, the gases will be free to come out and escape.

A common example is an unoccupied guest bathroom or basement shower cubicle, or some other fixture that isn’t utilized on a consistent basis.


The source of this stench is a vent stack located on the roof. In your home, each drain has a vent stack linked with it, which is the little pipe(s) that can be seen protruding from the top of your roof. These pipes are intended to exhaust the gases produced by the septic system via the roof of the house. They also aid in the drainage of wastewater via the plumbing system, preventing the formation of air-locks in the system. Due to a downdraft, depending on where the vent pipe exits the roof, the height of the pipe, the height and form of the roof, as well as the direction and speed of the wind, the gases may be forced back down into your patio.

Why do drain fields fail?Is there an easy fix to a failed drain field?

When it comes to your home’s little wastewater treatment facility, the drain field is the final component. This is where the effluent is purified so that it may be reused after it reaches the groundwater table and is treated. Consequently, it is critical that the drain field be thoroughly cleaned and cleared. When there is an excessive accumulation of solid waste materials in the tank, the drain fields are severely impacted. This occurs when the sludge is not digested properly due to a depleted bacterial population, a tank that has not been pumped on a regular basis, or when an excessive amount of water is fed into the septic system, stirring up hardened wastes and transporting them to the drain field.

  1. Only around half of the particles in a septic tank are broken down by bacteria, with the remainder accumulating at the bottom of the tank until it is drained out.
  2. Time required for this to occur is determined mostly by the size of the household, but also by the size of the septic tank.
  3. If this occurs and is not addressed immediately, it is almost certain that the remainder of the septic system will collapse.
  4. It is necessary to understand that each septic system is built to manage a set volume of wastewater, which is determined by how many people live in the house.
  5. If a family overloads a system by using far more water than is necessary each day, the drain pipes will never have enough time to dry.
  6. Because this slimy membrane does not allow water to soak through it, the trenches are no longer capable of handling the effluent.

At this stage, simply emptying out the septic tank will not be sufficient to repair the system. In this case, depending on how severe the problem is, one of our drain field repair services, or a new drain field, will be required.

  • For drain field repair, Caustic Soda is used
  • Terralift is used for drain field repair and rejuvenation

Do you need to vent a septic tank?

A venting system is required for your septic system, as well as any sewage systems for that matter, in order to enable gases to escape and prevent harmful buildups or airlocks from forming. You should have three types of pipe ventilation in your septic system: an inlet and an outlet, a roof vent, and pipe vents in the yard. The air enters through the roofvents of the home’s plumbing and departs through the lowervent in the field, according to the manufacturer. Air cannot be drawn through to feed the aerobic bacteria in the leach field unless there is a ventilation pipe at the other end of the pipe.

  • In some instances, a ventpipe is insufficient.
  • These ventpipes, which are located on the roof, allow gases to escape from your sewer system.
  • If they get clogged, your system will be unable to properly drain.
  • There are various methods in which your septic system may be ventilated.
  • That ventpipe really pushes smells from the septic system up through the house and over the roof level.
  • This serves as a type of treatment for the waste water, which may then be absorbed into the ground.

Correct Septic Venting = No odours!A simple guide to eliminate odour issues

Anaerobic bacteria are responsible for the activity in a septic tank. Anaerobic indicates that the bacteria do not receive oxygen from the surrounding environment. Due to their anaerobic activity, smells are produced, the most frequent of which is hydrogen sulfide gas, which is toxic to humans. The odor of hydrogen sulfide is similar to the odor of rotting eggs.not particularly pleasant! Although there is not a huge volume of gas produced in a septic tank, the gas must be evacuated in order to prevent pressure from building up in the tank.

  1. It is critical to be cautious of what you flush down the toilet and into the sink, among other things.
  2. It is also possible for downdrafts to be caused by wind blowing over surrounding trees that are taller than the house.
  3. As a result, the scents may only appear every now and again.
  4. What are some of the possible remedies to the odor issue?

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!


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.


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.


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).


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.

examples of settled sewer pipes:

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.


Solids are kept in the septic tank and away from the disposal area with the use of concrete baffles. Using baffles to reduce agitation of wastewater entering the septic tank and prevent particles from escaping the tank and entering the drainfield, baffles can assist avoid drainfield damage and extend the life of the drainfield.

If the baffles are broken, missing, or have never been placed, the drainfield’s life expectancy will be reduced significantly. Baffle repair normally entails the placement of a plastic tee at the end of the sewer pipes to prevent them from clogging.

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.
