What Is The Purpose Of The Tee Inside Of The Septic Tank?

Elaborating: a “tee” or baffle system keeps floating solids from passing out of an opening, allowing just effluent to pass. That’s why conventional septic tanks use a tee or baffle at both inlet and outlet ends of the tank – to keep from clogging piping at inlet or drainfield at outlet.

  • In some designs the septic tank inlet baffle or tee also reduces the movement of sewer gases out of the tank and up into the building through an un-trapped sewer pipe. The septic tank baffle or tee is a device on the inlet or outlet of a septic tank which prevents sewage back-flow into the inlet or outlet pipe.

How does a baffle tee work?

The baffle is inside the tee and it directs the water, that is being ejected from the disposal with force, downward. With out the baffle the pressure is to great and the water will shoot the wrong way. In the photo below the water comes from the disposal on the right, the baffle is in the tee.

What is a sanitary tee in a septic system?

The purpose of the inlet sanitary tee is two fold: to direct flow from the house sewer downward into the tank to create a longer detention time for the sewage to allow settling of solids, and to keep the floating scum layer from plugging the inlet pipe.

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.

What is the pipe sticking out of my septic tank?

The white PVC pipes that stick up in the area of your drain field offer a “window” into how well it is operating (draining). They shouldn’t be removed but they can be cut down, level with the ground. Your septic system may have a “candy cane” vent pipe over the pump tank.

Do all septic tanks have baffles?

Every septic tank contains two baffles, one at the inlet and one at the outlet.

How often pump septic tank?

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

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

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

How many loads of laundry a day are safe to do with a septic tank?

Spread Out Laundry Loads These use less water which puts less stress on your septic system. Regardless of the type of appliance you have, you should still spread out your loads. Instead of doing several loads in one day, consider doing 1 load per day or space out 2 loads if you must do more in a single day.

Why do septic tanks have buffer walls?

What is the purpose of a septic tank baffle? The purpose of the inlet baffle is twofold: to direct flow from the house sewer downward into the tank to create a longer detention time for the sewage to allow settling of solids, and to keep the floating scum layer from plugging the inlet pipe.

How often should a 1000 gallon septic tank be pumped?

For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.

What are the blue pipes sticking out of the ground?

While natural gas and electricity power most furnaces today, many pre-1970s homes had fuel-oil powered furnaces and with that came an underground fuel oil tank. Evidence of this reveals itself in that pair of galvanized steel pipes sticking out of the ground within a couple feet of each other.

How do you hide septic vent pipes?

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.

What are the two pipes coming out of my septic tank?

Your home’s plumbing system is designed to efficiently remove water and waste. Its drainage and vent functions are actually two systems that work together. Drainage pipes carry waste out of your home to either the city sewer or a septic tank.

The Role of the Sanitary Tee

What is a Sanitary Tee? All septic tanks are made with an opening for the waste to exit the tank into the septic drainfield. This opening is called the outlet.

If the sludge layer at the bottom of the tank and/or the scum layer at the top of the tank get too close to the exit of the outlet tee.

An additional insurance to prevent waste from entering the drain field, is an effluent filter.

When a drain field fails, the drainlines are no longer able to absorb wastewater, and the waste could eventually back up into the house.

Not only would you be preventing extensive damage to your septic drainfield, you may also prevent damage to the inside of your home – potentially saving thousands, or tens of thousands in repair.

Professional Septic Tank Pumping

When it comes to septic systems, the outlet tee is one of the most crucial components because it is positioned inside the septic tank. The photo at the bottom shows an outlet pipe inside a septic tank that does not have an output tee. Using an outlet tee, you may prevent particles from flowing directly into the exit pipe, where they would otherwise end up in your distribution box and subsequently your leaching field. If the outlet tee is left disconnected for an extended length of time, the particles may eventually clog the pipes in your leaching field, resulting in a septic system failure.

The top photo shows a freshly fitted outlet tee on a septic tank in Norton, which was just installed on a residential property.

Another illustration of the adage “you get what you pay for.” Septic pumpers are required to visually inspect your whole tank as part of their work description.

A reputable pumper will take the time to check your tank and educate the homeowner on appropriate septic system maintenance and repair. Sewage treatment will be provided by Ribeiro Enterprises in Norton, Mansfield, and Attleboro, Massachusetts.

Sanitary Tee And Filter Replacement

The presence of odors surrounding the drainfield might be caused by a loss of septic sanitary capacity in the septic tank. Of course, such scents might also be indicative of a malfunctioning drainfield, necessitating a more thorough investigation. Checking for the presence and condition of the septic tank outlet tee should be done at the septic tank and should be a quick and simple procedure. While it is important to repair an outlet tee if one has been lost, you should also consider that the drainfield’s future life will be significantly diminished.

  • For the reason that septic tank tees are both a probable source of and a diagnostic assistance in the event that your septic system emits foul scents or aromas.
  • The first is to direct the flow from the house sewer downward into the tank in order to create more detention time for the sewage, which will allow solids to settle out, and the second is to prevent the floating scum layer from blocking the inlet pipe.
  • The tees we use now improve on the first purpose by incorporating effluent filters, which prevent big floating particles or debris from going downstream via the tee.
  • So, what exactly is a tee?
  • Clay, concrete, and PVC pipe are all acceptable materials for making them.
  • It can also assist in preventing sediments from backing up toward the house if you should encounter a septic system backup at your home or business.
  • When we open a septic tank, we frequently find that one or both of the tees are missing or damaged.
  • When we notice that a tee is missing, we glance at the bottom of the tank as it is being pumped to see if the tee has fallen off somewhere along the way.

If you have a septic tank that is pumped on a regular basis, the pumping specialist should be inspecting the baffles. Sanitary tees can be replaced and installed by Lentz Wastewater.


If your septic system becomes clogged and you find yourself having to clean the filter on a regular basis, you might be tempted to simply remove the filter altogether. Hold on to it. Solids, wastewater, and scum are separated into three levels in septic tanks, which allows them to function properly. Solids sink to the bottom of the container, where microbes breakdown them. The scum, which is made up of trash that is lighter than water, rises to the surface. In the drainage field, the middle layer of effluent leaves the tank and goes through an underground network of perforated pipes to the drainage field.

  1. Keep the outlet effluent filter in place since it is required by your state’s health law.
  2. Waste particles may flow through the filter and block the drainfield if it were not installed.
  3. Your filter, on the other hand, should not require cleaning every six months.
  4. A good chance is high that you’re flushing filter-clogging things down the toilet, such as grease, fat, or food scraps.
  5. A garbage disposal will not be able to break down food particles sufficiently to allow them to flow through the septic tank filtration system.
  6. Plastic items, disposable diapers, paper towels, nonbiodegradable goods, and tobacco products will clog the system if they are flushed through it.


By Admin on November 12, 2020 Your efforts to live as environmentally conscious as possible, as a responsible homeowner, are likely already underway, with practices such as recycling, composting, and purchasing energy-efficient equipment among your list of accomplishments. As a septic tank owner, you want to be sure that anything you put into your tank and septic field is causing the least amount of ground contamination as is reasonably practicable. Fortunately, there are a number of modest improvements you can do immediately to make your septic system even more ecologically friendly than it already is.

  1. Have your septic tank inspected and pumped on a regular basis.
  2. A bigger septic tank with only a couple of people living in your house, for example, will not require pumping as frequently as a smaller septic tank or as a septic tank that must manage the waste products of multiple family members will require.
  3. When in doubt about how often to pump your septic tank, consult with a professional for advice.
  4. In addition to locating and repairing any damage, a professional can ensure that the septic field is in good working order and that your septic tank is functional, large enough to handle your family’s waste, and not causing any unwanted pollution in nearby ground water.
  5. Avoid flushing non-biodegradable items down the toilet or down the toilet.
  6. Items that are not biodegradable are unable to properly decompose in the septic tank and might cause the system to get clogged.
  7. In addition to causing issues in your house, septic system backups can damage ground water in the area surrounding your septic field.

To a Tee

Please provide opinion on the installation of an intake tee within the septic tank, which I am considering. I wanted to know if anyone had any issues with these because Alabama has only recently mandated that we put them in. Answers: *** In my opinion, a primary garbage tank/compartment should be equipped with both an input baffle and an exit baffle to ensure proper drainage. For a supplementary garbage tank or compartment, the same holds true: they are necessary. Otherwise, the solids and FOG will not be able to build in adequate quantities in the tank.

  • The outlet baffle assists in preventing the majority of floaters from exiting the tank and should collect water from the clear zone in order to transfer it to the next step.
  • At the very least, it is what I do.
  • *** The inlet tees of a tank appear to be in good working order.
  • They are also an excellent retrofit for tanks that have failed to maintain proper entrance baffles.
  • When wearing a tshirt, it appears to fall to the ground.
  • Just make sure that you have an inspection port above the tee, so that you can clear it if it becomes blocked at any point in time.
  • Question: I’d want to ask you a question concerning septic odor.

These are the addresses of the residences where I installed the system.

The plumbing for the majority of the residences was done by the same plumbing business.

They do return when the homeowner requests it, but they never discover anything wrong.

Almost every occasion, removing the outlet tee or baffle and replacing it with a 90-degree elbow has provided a satisfactory solution.

Answers:*** I’d want to be clear on the location of what you refer to as the output tee, if that’s possible.

That being the case, I would be hesitant to install a 90-degree elbow on this unless it was equipped with a vent that could be drilled into it.

It is possible to utilize a 90 with no vent and yet have enough fall from the tank to the distribution box or dosing tank.

As a result of the surge, it is likely that additional solids will be drawn into the absorption region.

In this case, the installer is not at blame, but he or she can acquire trust by correctly diagnosing the issue.

*** Because the 90-degree elbow drains below the surface of the water, the septic system is prohibited from venting out the house stack.

It appears that a P-trap is missing between the home sewage and the septic tank, according to the sound.

Due to the fact that gas in the septic tank now has nowhere to go, this might result in a new problem.

When it comes to diagnosis, there are several possibilities: It is possible that the P-trap will siphon dry if the roof vent is located too far away from the fixture it is supposed to feed.

In addition, there is a siphon break.

When a house is left uninhabited for an extended period of time, the water in the P-traps might evaporate.

I’m baffled as to why.

*** That there is a P-trap buried in the line outside of the house is beyond belief.

I can’t for the life of me figure out why someone would install a trap in the tube that runs from the foundation cleanout to the tank.

It has to be released in some way, to some destination.

*** I do all of the plumbing from the home to the tank and beyond, which is about two feet outside the house.

With special attention paid to the overdig of the basement, all pipe is bedrocked in stone.

There are no P-traps to be found.

They came with a plastic baffle on either end to keep the wind out.

The odor was generally highly apparent and appeared practically soon after the incident.

On some of the residences, the plumbing vents through the roofs were replaced with new ones.

It is mandatory for us to leave the tanks’ risers extending to the surface level where we live in Indiana.

This was ineffective.

No explanation has yet been provided for why the stench disappeared when a 90-degree elbow was inserted on the tank’s outflow end. The intake end of multiple tanks was fitted with a 90-degree elbow, which worked well (against our better judgment). This only worked once or twice.

Everything You Need to Know About Your Septic Tank

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

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

These are:

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

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

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

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

Septic Tank Inlet Baffle

The connection that connects your home to your septic tank is referred to as a “inlet” line. An “inlet baffle” has been put on the interior of the tank for this particular line. An intake baffle that has been correctly maintained sends incoming trash downward, below the liquid level, limiting disruption of the liquid and solid layers within the tank, as shown in the illustration. A correctly operating inlet baffle prevents solids and the floating top layer, commonly referred to as the FOG (fats, oils, and grease) and/or Scum layer, from overflowing into the outlet line and into the absorption component (either a “field” or a “seepage pit,” from entering the system.

Septic Tank Outlet Baffle

Each system has an absorption component that is connected to the septic tank through a “outlet” connection on the “inlet” side of the tank. It is recommended that this line be equipped with an exit baffle, which keeps the scum layer and any trapped materials from entering the disposal area or leach field. It is necessary to replace a disintegrating or missing outlet septic tank baffle in order to maintain the integrity of the disposal area and to keep your septic system operating at peak performance.

Septic Tank MaintenanceBaffles

During routine septic pumping or a residential septic system inspection, your Wilson Services’ technician will find the inlet and outlet locations of the tank and determine whether or not the baffles are currently in place and in good working order. Depending on whether or not we find one to be in poor condition or missing altogether, we may propose that you invest in a baffle replacement, which is an ideal method for you to extend the life of your septic system. A fully operating sewage system must not only empty into the tank but also remain in the tank until the next septic pumping is done, and the only way for this to happen is with properly functioning septic tank baffles.

Trucks+ Receive Notifications I’m not sure what the function of a septic tank baffle is. In response to a recent inspection report indicating that the baffles need to be fixed or replaced, this is a question that many homeowners have asked themselves. As a result, it is a reasonable query, given that your clients are aware that they would be required to spend money. Before responding to the question directly, it is necessary to provide a quick description of the interior of their tank.

Upon evaluating the tank, if any of these three layers are missing, the service provider is on a quest to identify what is causing the problem.

One or both of the septic tank baffles have been removed or are somehow damaged.

The intake baffle has two purposes: it directs flow from the house sewer downward into the tank, allowing for a longer detention period for the sewage to allow for the settling of particles, and it prevents the floating scum layer from clogging the pipe leading into the tank.

These days, we may improve the first function by utilizing effluent filters to prevent big floating particles or debris from entering downstream into the water supply.


Baffles are generally classified into two categories: plastic sanitary tees and wall baffles. There are built-in baffles in the walls that often provide extra space for the particles transported by the home sewage to pass into the tank. Having said that, due to the nature of their design, sanitary tees are less prone to experience clogging issues. If the baffles are fitted correctly, any kind will function adequately. However, if the tank is not properly installed, baffles can quickly degrade and cease to function as they should.

  1. Retrofitting a sanitary tee is typically used to repair wall-attached baffles when they get damaged or worn out over time.
  2. These days, it’s scarcely necessary to say it because experts are well-versed on the distinction.
  3. Many prefabricated septic tanks now have a sanitary tee that has already been fitted.
  4. When connecting a wall baffle, be sure that the connection does not corrode.
  5. Baffles manufactured of PVC sanitary tees must be correctly bonded and fastened to the inlet and outlet pipework in order to function effectively.
  6. Often, when a wall baffle is replaced with a sanitary tee, the patching around the hole is inadequate, enabling roots or surface water to enter the tank.
  7. If there is an effluent screen, it should be inspected to determine if it needs cleaning.


Examine the input pipe and the wall baffle during a routine inspection to ensure there is sufficient free space to enable free passage of water and sediments into the tank. There should be 2 to 4 inches of room between each item. Typically, this is caused by improper installation, where the pipe was forced past the inside wall of the tank, hence lowering the amount of room available for solids to flow through. Consequently, toilet paper can accumulate in the pipe, clogging it and causing backups into the home.

An additional consideration at the intake is the type of pipe that was utilized for the household sewer line.

This type of pipe can react with soap products, creating corrosion and clogging the pipe, as well as generating flow difficulties in the pipeline.

Similarly, the outlet baffle should be checked to ensure that it has enough room. This is less important since the outlet baffle should extend to a depth that is equal to 40 percent of the working depth of the tank, sucking clear liquid out of the tank, making it less vital.


It is necessary to inspect the pipe leading into and out of the tank to see whether it is straight in and out. If the pipe is “cocked” at an angle after installation as a result of settling, it will need to be repaired. This scenario can result in pipe obstructions and backups, as well as contribute to venting and corrosion issues in the water system.


In its most basic form, your septic tank separates liquids from solids, then retains the solids until they can be pumped out while sending the liquids to a distribution field. However, this system is far more complicated than it appears at first look. However, these procedures might be a little more sophisticated than they appear at first glance. It is possible that certain sections of the tank, even if they are the simplest and most basic, may need to be replaced from time to time, such as the baffles at the entrance and outflow, as well as the baffle filter (also called effluent filter).

  • FUNCTIONS OF THE SEPTIC BAFFLE Septic baffles are situated at the intersections where pipes enter and exit the tank to prevent clogging.
  • In many cases, the outlet baffle is regarded as the most critical baffle, since it prevents particles from departing the tank and making their way to the leach field, where they might clog and effectively damage the leach field system.
  • Unfortunately, this baffle is also the first to give way under its own weight.
  • Its purpose is to aid in the smooth flow of wastewater into the tank while minimizing disturbance of the scum layer.
  • MATERIALS FOR SEPTIC BAFFLE Several types of septic baffles are available, some of which are constructed of concrete and others, particularly newer variants, which are composed of plastic such as ABS.
  • The exit baffle is frequently equipped with an effluent filter, which increases the effectiveness of the baffle in terms of keeping solids out of the leach field.
  • The effluent filter will need to be updated on a regular basis after that, but this is a small price to pay for avoiding having to redo your leach field as a result.
  • Once a year, or whenever your tank is drained out, you should have the concrete baffles evaluated for structural integrity.
  • Among the other baffle issues include blocked outlet baffles or outlet baffle filters, leaks at the baffle-to-tank connection, and inlet baffle obstructions, among other things.
  • Baffle blockages can also arise as a result of tree roots entering the system through the input pipe or around the baffle.

Need Help on Plumbing a Sanitary Tee into a Septic Tank

AN IMPORTANT NOTE ON PUMPING SEPTIC TANKS Once a year, check both compartments for solids accumulation and pump them out before enough solids collect in the first compartment to cause spillage into the second compartment. Typically, tanks are less than sixteen inches in diameter – check with the manufacturer of your tank. To examine the level of solids at the bottom of your septic tank, wrap a piece of white towel around the end of a long pole and poke it into it. If your septic tank is healthy and correctly proportioned, it may never need to be pumped.

  1. As a result of the accumulation of particles, grease, and sediments in the leach field percolation region, the ‘biomat’ ultimately fails and needs to be replaced.
  2. If you reside in a very cold environment, you should never have your tank pumped in the fall or winter; you should only have it pumped in the spring.
  3. After having your septic tank pumped, make sure to promptly refill it with water.
  4. This is especially true when the soil is damp and when tanks are not adequately bedded with a sufficient amount of gravel before being filled (selective, draining backfill).
  5. An empty concrete and fiberglass tank may fracture and leak if subjected to significant pressure, and it will ultimately need to be removed and replaced.
  6. Larger particles are prevented from exiting the tank and jeopardizing the leach field by plugging soil pores and causing failure.
  7. Septic filters are a low-cost form of insurance that may be readily installed in the second compartment of your septic tank.

Author:Septic Tank Yank (CO)Cebirds, many old septic tanks were fitted with a 90 degree elbow to provide an outlet baffle.The purpose of an outlet baffle is to prevent floating material from passing from the tank into the leach field.The 90 degree elbow will certainly accomplish this task, but some material that finds its way into a septic tank is actually suspended in the “sludge free zone.”So you see, in reality there is no sludge free zone in a typical septic tank.Inorganic material, which will never decompose, such as plastic bags, tampon applicators, condoms, tooth brushes, and plastic toys may flow through the tank and become lodged at the bottom of the outlet baffle.These items will catch other suspended material, such as facial tissue, sanitary napkins, disposable diapers, paper towels, and cigarette filters and then a clog is formed.Typically this clog is removed when the contents of the septic tank are removed.But be assured that the clog will occur again.The best approach for providing an outlet baffle on a septic tank is to install a 4-inch sanitary tee.This tee can then be fitted with a septic tank effluent filter.The filter, if properly installed, will prevent the lodging of those inorganic materials that I mentioned above.I prefer the SIM/TECH FILTERS “bottle brush” type filter.You can view this filter and a drawing of a typical septic tank outlet baffle on SIM/TECH’s website.SIM/TECH FILTERS advertises the STF-110 filter, a big bottle brush type, as a disposable item and recommends that it be changed annually.I have merely cleaned the filter on my septic tank outlet baffle for the past 3 years and it is functioning just fine.I simply raise the filter to the top of the tee and clean the accumulated debris with a strong stream from a hose back into the tank.Of course, SIM/TECH FILTERS wishes to sell many of these filters.They cost only about $20, but I am quite frugal and will continue using and cleaning this same filter until it is no longer effective.It is important that access to the outlet baffle and filter is an easy chore.Therefor, I recommend that 20-inch diameter “Tuf-Tite” risers be installed over the outlet end access hole of the tank.This riser should extend to the ground surface so that it is visible and easily accessed.The gasketed lid is secured with 8 stainless steel screws on the top and 2 stainless steel “safety” screws on the side of the lid.Post Edited

Septic Tank Installation – Stangland Septic Service – Aberdeen, WA

Most septic tanks are rectangular or cylindrical containers that are buried underground and are constructed of concrete, fiberglass, or polyethylene. The tank is filled with wastewater from your toilet, bath, kitchen, laundry, and other sources. Heavy materials sink to the bottom of the tank, where they are partially decomposed by bacterial activity, resulting in digested sludge and gases. Fats and oil, among other lighter particles, float to the surface and form a scum layer on the surface of the water.

  • The use of two compartment tanks, which are more effective in settling solids, is necessary for modern systems.
  • This device slows the flow of entering wastes and lowers the amount of disruption of settled sludge caused by the wastes.
  • All tanks should have easily accessible lids so that the status of the baffles can be checked and the tanks may be pumped in both compartments.
  • In the septic tank, solids that have not decomposed are left behind.

Most septic tanks need to be pumped every 3 to 5 years, depending on the size of the tank and the amount and kind of particles that are introduced into the tank during operation.

Proper design and installation of a septic system is essential for the systemto work properly. Just as importantly, all work must be done according to various state and local ordinances designed to protect the environment. Connecticut Public Health Code regulations require that new septic tanks have a minimum capacity of 1,000 gallons and 1,250 gallons if a garbage disposal is installed.Shoreline Sanitationhas the knowledge, expertise and experience to design and install a septic system will last for years, ensuring that your investment will result in a trouble-free septic system, provided that you maintain the system properly with regular cleanings.

All solid and liquid waste flows through your house’s plumbing out yourhouse-septic line (1)into aseptic tank (2). Inside the septic tank, liquids and solids separate, with the solids sinking while the liquids remain near the top.Most solids are further broken down by bacterial action, but some remain as scum.Older septic tanks may be single chambered while newer systems have dual chambers to further separate and filter the liquids. Newer systems after 2000 also incorporate anoutlet baffle filter (3)whichkeeps even more contaminants inside the tank. The liquids then flow out through adistribution pipe(4)into adistribution box (5)and diffuse through aleaching system (6), where they are naturally diffusedand filtered.The proper maintenance of your septic system involves removing the scum before it can build up and infiltrate the distribution piping and leaching system. Regular cleanings are far cheaper than repairs.
  • DO check with the town sanitarian or the director of health for recorded information on a house’s septic system if you are considering purchasing it. In the event that no records are available for a specific house, check with several local cleaner/installer firms to see if you can track down the company that performed the original installation
  • DOhave your tank pumped out, effluent filter cleaned, and system checked by a licensed and COWRA-affiliated septic contractor on a regular basis
  • DOinstall a riser. Cleanout covers must be within 12 inches of the ground, according to state statute “relating to the earth’s surface Cleanout covers any area that exceeds 12 square meters, according to code “Do the following: DOset up and adhere to a sound system of inspection and cleaning
  • DOeducate your family on how to properly use the system within the confines of these guidelines
  • DOleave the area over the drain field undisturbed with only a mowed grass cover. It is possible that roots from nearby trees or shrubs will clog and damage your drain lines
  • DO conserve water where possible. Check for leaky fixtures in the plumbing, such as toilets, tubs, showers, and sinks. A constant leak or trickle might cause a drainage system to become overloaded. Dishwashers and washing machines should only be used when they are completely full. Invest in water-saving appliances and incorporate water-saving features into faucets, toilets, and showerheads
  • Dispose of household chemicals through an approved hazardous waste collection carrier
  • Keep a record of the dates of system cleaning in the permanent house file so that the information can be passed on to the next owner
  • Divert roof drains and surface water from driveways and hills away from the septic system. Additionally, sump pumps and house footing drains should be routed away from the septic system
  • And DOtain a working knowledge of the location of your septic tank and drain field. Keep a sketchbook with you when you go on service calls.
