  • Most concrete or metal tanks have about a 2 ft portal with about a 6″ in portal in the middle of the 2 ft portal so you have the option of using 2 different portals. Fiberglas or plastic tanks have about a 30″ portal. Some septics tanks are homemade so it is hard to tell what they have.

How wide is septic tank lid?

During the search, keep an eye out for a circular lid approximately two feet wide. Septic tank lids are typically green or black plastic; sometimes they are made of concrete. It’s not always easy to find the lid, though, as unkempt grass, dirt, or debris can conceal the septic tank lid.

How far apart are the holes in a septic tank?

Once you determine where the inlet is, measure the distance from the center of the inlet lid towards the opposite end of the tank to locate the outlet lid. The distance between lids will be different for each sized tank: 1000 gallon tank = 6-6.5 ft.; 1250 gallon = 7-7.5 ft.; 1500 gallon = 8.5-9 ft..

How big is an old septic tank lid?

If your septic tank was installed after 1975, it will probably have two polyethylene or fiberglass lids centered at opposite sides of the perimeter. Older tanks will typically have a 24-inch concrete lid right in the center of the tank.

What size pipe goes into septic tank?

Four-inch pipe is standard, and it should extend far enough under the house to connect with the main soil stack, which is a 3-inch pipe that extends vertically past the main bathroom and through the roof.

How many lids are on a septic tank?

In order to make repairs or perform regular maintenance or cleaning/pumping of the tank, access must be provided. There are usually two lids located at the top of the septic tank-one located over the inlet “T” and one located over the outlet “T” (see “Septic Components: Septic Tanks”).

How many lids are on a 1000 gallon septic tank?

Single Compartment 500 – 1,000 Gallon Septic Tanks: Installed up to approximately 1976, this tank style will have one main lid and two smaller baffle lids on both ends of the tank as shown in the diagram below.

How far should drain field be from septic tank?

Common guidelines require at least 50′ clearance distance between a well and a septic system tank or 150′ between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances. Local soil and rock conditions can make these “rules of thumb” unreliable.

How far should a septic tank be from a house?

Most importantly, a septic tank must be at least seven metres from a house, defined as a ‘habitable property’. Septic tanks are built underground and release wastewater slowly into the surrounding environment. For this reason, they must be a set distance away from a home.

How do I know my septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

  1. Your Drains Are Taking Forever.
  2. Standing Water Over Your Septic Tank.
  3. Bad Smells Coming From Your Yard.
  4. You Hear Gurgling Water.
  5. You Have A Sewage Backup.
  6. How often should you empty your septic tank?

What size should a sewer line be?

Main Sizes – The minimum size sewer main within a residential development shall be 6-inches in diameter. The minimum size sewer main for commercial and industrial developments shall be 8- inches in diameter.

What kind of pipe goes from house to septic?

The septic tank should be positioned at least 50 feet from the house proper. ABS or PVC plastic or cast iron pipe can be used to connect the tank to the house drainage system. [We do not recommend using clay pipe nor “orangeburg” pipe.]

What is the fall on a 4-inch sewer pipe?

For 4-inch PVC piping and a building sewer less than 50 feet long, the minimum slope is 1 inch in 8 feet, or 1/8-inch per foot, and the maximum is 1/4-inch per foot. For sewers longer than 50 feet, the slope should be 1/4-inch per foot.

How many openings does a septic tank have?

Asked in the following category: General The most recent update was made on April 2, 2020. Every septic tank appears to be unique, however some have three access holes. In most cases, the modern tanks feature a modest access point above the intake and outflow pipes, as well as a third access point in the middle for cleaning purposes. Aseptic tanks erected prior to 1975 will have a single concrete cover measuring 24 inches in diameter in the center of the rectangle. The lids of a two-compartment tank erected after 1975 will be made of fiberglass or polyethylene, and they will be centered at opposing ends of the tank’s rectangular shape.

What size is a septic tank lid?

Find the location of TheLid The majority of septic tanks are rectangular in shape and measure around 5 feet by 8 feet. Probe around the tank to identify its boundaries and draw a rectangle around the outside of the tank. The center of a rectangular aseptic tank with a single 24-inch concrete cover erected before to 1975 will be the center of the rectangle. The cost of a standard septic tank replacement lid can range between $30 and $70. Do septic tanks have concrete covers, in the same way? The majority of concrete septic tanks are constructed with thick concrete lids over the manholes and access holes, which are subsequently filled with soil.

In a similar vein, you could wonder how to fix a septic tank cover.

  1. The first step is to locate the septic tank. To remove and replace the septic tank lid, search for and locate the septic tank. Identify the type of replacement lid that will be required in Step 2. Utilize a measuring tape to decide the size of lid you will want. Most lids are either 21 inches broad or 24 inches wide, so choose wisely. The third step is to remove and reinstall the Lid.

Is it OK to cover the lid of my septic tank with dirt? Some homeowners, on the other hand, may find a pipe orlid in the middle of their lawn to be an eyesore.

When dealing with this issue, it is typical to place the riser’s lid a few inches below the surface of the lawn. Thelid can be covered with grass and a thin layer of dirt or another gardening surface in this manner.

The lids aid in the opening of the septic tank and the completion of different activities such as inspection, pumping, and repair.

In this post, we will cover how far apart the septic tank lids are spaced, why it is necessary to know the placement of the lids, and a variety of other topics.

So, the question is, “How widely apart are septic tank lids?” The distance between the lids of a septic tank is often varied depending on the size of the tank in question.

The distance between the lids of a 1500-gallon tank will be around 8.5 to 9 feet.

Often, homeowners are unaware of how critical it is to be aware of the placement of the septic tank lid and the septic tank itself. Despite the fact that septic tanks are fairly huge, they are often difficult to discover. This is especially true when they are not kept up to date. If you are aware of the placement of the septic tank lid, you will be able to discover any problems with relative ease. At the case of floods, for example, you will be aware that there is an issue with overloading in that particular location.

You will also be able to ensure that no car has crossed it.

If the position of the tank is unclear, it is possible that it will be damaged unintentionally.

In order to locate the septic tank lids, you can do the following steps:

  • Examine the Map– This is the quickest and most straightforward approach. In addition to showing the location and dimensions of the septic tank, the property map will also include a diagram. You will also receive this diagram as part of your home inspection documentation.
  • Keep an eye out for signs– Consider taking a close look around your yard. You will very certainly come across some low places or even high spots, which will indicate the presence of the hidden tank and will require more investigation. Occasionally, the grass returns to the location and takes on a distinctive appearance from the surrounding areas. Consequently, keep an eye out for strange mounds in the yard.
  • Consider the Pipe– This is a simple method for locating the lid of septic tanks. The septic tank is often built along the length of a sewage line. This will encompass the area between your home and the front yard. So all you have to do is keep track of where the pipes are traveling and where they are coming to a halt. Their final destination will mostly certainly be the location of the septic tank.
  • Locate the Lid– As soon as you locate the septic tank, you will be able to locate the lid within a short period of time. The lid is often located in the middle of this rectangle. Some septic tanks will have two lids, while others will only have one. This is determined by the year in which the septic tank was erected
  • Nonetheless,

Remember to make a note of the position of the septic tank lid as soon as you discover it. As a result, you will not have any difficulties in locating the lids the next time.

When searching for a septic tank, you must begin the process of excavating so that you may lift the lid of the tank. A shovel can be used to remove the septic tank lid from the tank. It contributes to the excavation of the ground immediately surrounding the tank.

In most cases, the earth is dug such that there is 16 inches of space on each side of the lid on the different sides. The fact that you are sloping the land while excavating is a positive thing. As a result, the gravel is not thrown back throughout the process.

How to Lift the Septic Tank Lid?

The lid of a septic tank is often rather hefty, as is the tank itself. It is often a large slab of concrete that is completely flat on all sides. It is frequently equipped with a handle that allows it to be pulled. Pry bars are usually required to pull the septic tank out of the ground in most situations. It is necessary to position the pry bar before pressing it down. In order to raise the lid from the hole, you will want assistance once again. Once you have successfully lifted it, you may move it to a safe location where it will not interfere with anything else.

Tips to Maintain the Lids of Your Septic Tank

When you find the septic tank lid, you must make certain that it is in good working order. You will not have to be concerned about any harm if it is kept in good condition. Furthermore, you may be confident that it will be accessible to specialists whenever they require it. Here are some pointers to keep in mind when maintaining your septic tank lid:

  • Check to be that there is nothing heavy on the septic tank’s lid before closing it. Because of this, the lid is not designed to resist or retain large objects. You must take care to keep the grass and plants surrounding the septic tank as short as possible.

Make sure that no big trucks pass over the septic tank lid by marking the area. Furthermore, you will not have any difficulties locating the tank the next time you need to use it as a storage container.

It is true that the majority of septic tanks have a concrete cover because it prevents odor from escaping. Concrete lids also help to prevent sewage from leaking into the soil.

  • In what amount will I be required to pay for a new septic tank cover

Replacement lids for septic tanks typically range in price from $30 to $70. Costs, on the other hand, are dependent on your area as well as the individual contractor.

  • When I mistakenly drive over a septic tank lid, what happens next is a mystery.

It is possible that the concrete will be harmed if you mistakenly drive over the lid. It has the potential to break, resulting in long-term difficulties. It is possible that a foul odour may be released, or that the entire system could fail completely. A single lid in the center of a tank that was put before to 1975 is not uncommon. Tanks that were installed after 1975, on the other hand, contain two chambers. As a result, there are two lids, one for each of the two sections. The two lids are separated by a short distance, making it easy to get to them both.

As a result, large-capacity tanks are typically equipped with two lids.

They give a means of gaining access to the system.

  • Here is an example of a septic tank cover that was discovered atop an unstable home-made collection of concrete blocks that had been piled by the owner to serve as an access well to his septic tank. Because the masonry blocks were misaligned and loose, and because the tank aperture into which the cover opened was bigger than the cover, there was a serious collapse risk that may have resulted in a deadly hazard. We covered the area with plywood and roped it off, and we quickly informed the residents and the property owner of the situation, both verbally and in writing

Procedure for Opening the Septic Tank Pumping Access Port

It is necessary to clean the septic tank using a cleanout port, which is normally positioned in the center of the tank. A small access opening, such as one over an intake or outlet baffle, does not provide enough space for adequate sludge removal from the septic tank bottom, and it increases the likelihood of future clogging of the tank’s inlet or outlet due to partially removed floating scum that has not been completely removed from the tank bottom. In this particular scenario, we already had the measurements to the exact placement of the septic tank cleanout cover due to previous work.

A wrecking bar is set to be used to remove the cover from the vehicle.

Reader CommentsQ A

@Ron, In order for a concrete septic tank lid to be correctly erected, it must feature both access openings and cast in iron loops to which a hoist may be attached. Alternatively, if your septic tank cover does not have those points of purchase for lifting, you will require a flat bar and a larger wrecking bar to pry up the excavated lid from the septic tank sufficiently to allow you to put a chain around the lid, most likely two Chainz, and lift the lid with a hoist and tripod mechanism or you will use an on-site motorized hoist.

  1. 1/2 x 27/4 removing the top of a septic tank @Phil, Although what you describe is theoretically doable, it may be less expensive and more rational to do so in a different way.
  2. This is due to the fact that just stitching a circular hole does not ensure that I am creating a hole through which the lid will not be dropped.
  3. Edge My concrete septic tank, which was constructed when the home was built in 1979 and does not have any manholes or openings for pumping out, is in poor condition.
  4. Is it feasible to cut two manholes using a concrete saw that are 20″/24″ in diameter and then build risers and a cover on top of them?
  5. Could you please share a picture of the tank top?
  6. It is common for the concrete top to be tapered; nevertheless, it may just be trapped by effloresent salts and filth.
  7. I have a feeling that simply tugging will not be effective.

This would have stopped leaks but would have made it extremely difficult to open the tank for the next person who needed to open the tank.

Repeat this process many times all around the cover’s perimeter.

For me, this has worked almost every time in the past.

It is recommended that you build a septic tank riser that is sealed to the tank top, as well as a new secure cover on top of the riser if your septic tank lid is not near to the ground level.

Never work on your own.

I’ve erected two wood 4x4s on top of the lifting ring to provide additional support.

All I’ve done three times is shattered those 4x4s.

Do you have any recommendations?

A septic tank pumping provider can remove plastic bags, tiny pebbles, and other debris from your tank, as well as the sediments, scum, and sludge that has accumulated there.

What is the best way to get them out?

When the septic tank is drained out, would it make sense to place a plastic bag over the top hole of the tank to keep the odors contained?

Gerard A plastic bag as a sewer line cap doesn’t seem right to me – it’s not durable, it’s the incorrect material if a cover is required, and if it’s a vent rather than an access pipe, the vent must be open to the atmosphere and protected from animal intrusion.

What is the function of this item?

A typical septic tank is equipped with clean out access covers that are strategically placed.

Maybe something as basic as a flat piece of concrete or stone will be sufficient, or maybe something more complex.

To be quite honest, I would have expected the contractor who dug the hole to be accountable for ensuring that the system was repaired and safe.

What should I do to solve it?

What store would I go to in order to acquire septic tank covers?

A few years ago, I had a beautiful new house built for me.

I have three plastic polylok lids, one of which is above ground and is for the pump.

I’d like to purchase risers so that I may build all three at a depth of around 6 inches below ground level.

What are the advantages and disadvantages.

Do you have any other suggestions?

I apologize for the lengthy post.

Sorry, but “True Bolt” isn’t a phrase I’m familiar with or associate with septic tank lids in any way.

Although this is not always the case, Mary, as the pumper may be able to access the entire tank bottom from a single opening depending on the tank’s size and shape; however, if your pumper is unable to do so from a single opening, you may want both openings opened to inspect the condition of the tank baffles.

Reply:

If it’s a cesspool, rather than a septic tank, and it’s spherical, the access lid is normally located in the center of the container.

Question: how do i remove septic tank lid that is stuck

The entrance lid would normally be in the center of the cesspool, if it is in fact a cesspool rather than a septic tank, and it is spherical.

Reply:

Anon:WARNING: If the septic tank cover, lid, or access aperture has partially caved in or sank into the tank, the condition is extremely dangerous – an unsecure cover implies that someone might fall into the tank, which is generally lethal very quickly. Please keep everyone away from the septic tank area until such time as you have had the tank inspected and opened for additional inspection by a professional. Depending on the tank type and condition, lifting the lid may necessitate the use of a pry bar or wrecking bar, as well as a small portable winch (which is unusual).

Standard Septic Systems

When it comes to treating residential wastewater, a regular wastewater system combined with a soil absorption system is the most cost-effective technique currently available. However, in order for it to function correctly, you must select the appropriate septic system for your home size and soil type, and you must keep it in good working order on a regular basis.

What size septic tank do I need?

Septic tank size requirements are determined by the number of bedrooms in a house, the number of people who live there, the square footage of a house, and whether or not water-saving gadgets are installed.

If you want to obtain a general sense of what size septic tank your home requires, look at the table below.

Bedrooms Home Square Footage Tank Capacity
1 or 2 Less than 1,500 750
3 Less than 2,500 1,000
4 Less than 3,500 1,250
5 Less than 4,500 1,250
6 Less than 5,500 1,315

How often should my tank be pumped?

A regular pumping of the tank is required to maintain your system operating properly and treating sewage efficiently. Sludge collects at the bottom of the septic tank as a result of the usage of the septic system. Because of the rise in sludge level, wastewater spends less time in the tank and solids have a greater chance of escaping into the absorption region. If sludge collects for an excessive amount of time, there is no settling and the sewage is directed directly to the soil absorption region, with no treatment.

  1. You can find out how often you should get your tank pumped by looking at the table below.
  2. If you fail to maintain the tank for an extended period of time, you may be forced to replace the soil absorption field.
  3. Solids can enter the field if the tank is not pumped on a regular basis.
  4. Wet soils that have been saturated by rains are incapable of receiving wastewater.

Other maintenance

Another maintenance activity that must be completed on a regular basis to protect the system from backing up is to clean the effluent filter, which is located in the tank’s outflow tee and is responsible for additional wastewater filtration. This filter eliminates extra particulates from the wastewater and prevents them from being clogged in the absorption field, which would cause the absorption field to fail prematurely. You may clean the filter yourself by spraying it with a hose, or you can have your maintenance provider clean the filter for you if necessary.

Two critical components

A septic tank and a soil absorption system are the two primary components of a standard treatment system.

Tank

The septic tank is an enclosed, waterproof container that collects and treats wastewater, separating the particles from the liquid. It is used for primary treatment of wastewater. It works by retaining wastewater in the tank and letting the heavier particles (such as oil and greases) to settle to the bottom of the tank while the floatable solids (such as water and sewage) rise to the surface. The tank should be able to store the wastewater for at least 24 hours in order to provide time for the sediments to settle.

Up to 50% of the particles stored in the tank decompose, with the remainder accumulating as sludge at the tank bottom, which must be cleaned on a regular basis by pumping the tank out.

Drainfield

Ultimately, the soil absorption field is responsible for the final treatment and distribution of wastewater. Traditional systems consist of perforated pipes surrounded by media such as gravel and chipped tires, which are then coated with geo-textile fabric and loamy soil to create a permeable barrier. This method depends mainly on the soil to treat wastewater, where microorganisms assist in the removal of organic debris, sediments, and nutrients that have been left in the water after it has been treated.

See also:  What Are The Measurements Of A 1000 Gallon Septic Tank? (Solution found)

As the water moves through the soil, the mat slows its passage and helps to prevent the soil below the mat from being saturated.

The grass that grows on top of the soil absorption system takes use of the nutrients and water to flourish as well.

Septic tank types

There are three primary types of septic tanks used for on-site wastewater treatment: cisterns, septic tanks, and septic tanks with a pump.

  • In terms of on-site wastewater treatment, there are three primary types of septic tanks:

It is necessary for all tanks to be waterproof in order to prevent water from entering as well as exiting the system.

Factors in septic maintenance

All tanks must be waterproof in order to prevent water from entering as well as exiting the system during operation.

Soil types

There are three types of soil textures: sand, silt, and clay, and each has an impact on how quickly wastewater filters into the soil (a property known as hydraulic conductivity) and how large an absorption field is required. Sand transports water more quickly than silt, which transfers water more quickly than clay. According to Texas laws, these three soil textures are subdivided into five soil kinds (Ia, Ib, II, III, IV). Sandy soils are classified as soil type I, whereas clay soils are classified as soil type IV.

  1. The Hydraulic Loading, which is the quantity of effluent applied per square foot of trench surface, is also significant in the design.
  2. For this reason, only nonstandard drain fields are suitable for use in clay soils due to the poor conductivity of clay soils.

Common Septic Tank Facts

Septic systems are a low-cost and frequently successful alternative to conventional sewer systems. Concrete tanks have been the most frequent since the 1940s, with 3 – 500lids for a 1000 gallon tank and 4 – 500lids for a 1500 gallon tank being the most typical. Tanks began to be equipped with 16″ square concrete plugs with a lifting bail in the late 1990s, allowing for easier access to both sides of the tank. Many tanks today are made of fiberglass or plastic. Over time, the concrete might degrade, and the lids may develop cracks or possibly shatter completely due to the pressure.

  • Even broken lids should be replaced for the sake of the public’s safety.
  • They get access to your septic tank by removing green covers that are 20 inches in diameter.
  • This is done in order to prevent anyone, especially children, from removing a lid and falling into the container.
  • A typical water level for a tank should be 6″ below the top of the tank, and the tank should be kept completely filled at all times.
  • The level of the water is often a good sign of potential problems.
  • Additionally, it might suggest a clogged intake line, which could be caused by roots, a damaged pipe, or a loose joint.
  • If there has been a lot of rain, the earth may get saturated, making it impossible for any additional water to seep through the soil to the surface.
  • If your tank has allowed particles to enter the field lines, this might cause the openings in the corrugated pipe to get clogged, preventing water from percolating through the soil as effectively as it should be.

An output filter may be placed to prevent particulates from entering the field lines, but it would need to be cleaned on an annual basis to ensure that this does not happen. Nonetheless, it is far less expensive than rebuilding field lines.

Septic Tanks Risers- Bring Your Access To Ground Level

Getting a little tired of having to dig up your yard every time your septic tank has to be pumped out or serviced? Are you getting tired of dealing with incredibly hefty concrete lids? It appears that you are in need of septic tank risers in order to bring your access down to ground level! Our septic tank risers and covers are constructed of high-quality, heavy-duty polyethylene plastic, which makes them extremely sturdy and durable while also being lightweight and simple to handle.

THE POLYLOK ADVANTAGE

Septic tank risers are available in a variety of shapes, sizes, and designs on the current market. We believe our Polylok septic tank risers are the best money can buy in terms of quality. There are several causes for this, but the following are the most significant:

FACTORY INSTALLED GASKETS

The Polylok brand is the only one on the market that is sent to you from the factory with gaskets already in place, making it unique. This means that there is no further work necessary to ensure that the riser system is air and water tight! Keep ground water out of your tank, wastewater in your tank, and potentially hazardous gases out of your yard! In contrast to most other products, our Polylok septic tank risers do not require you to purchase or use any other type of sealant between each riser part.

INTERNAL STRUCTURAL RIBS

Once the hole has been backfilled, the structural ribs in the Polylok septic tank risers are inserted inside around each riser piece, providing them with tremendous strength and allowing them to maintain their shape under the pressure of the earth being pressed on them. As a result of the freezing and thawing of the ground in many parts of the country, it is necessary to have a smooth surface on the outside of the riser’s exterior. It is possible for items that have structural support on the outside of the riser to actually be lifted from the tank, causing damage to both the riser and seal, during periods of freezing and thawing.

LIDS WITH HANDLES

The access lid on a riser system is one of the most significant components since it is the part of the system that is visible from the outside and that must be removed every time the system is pumped or otherwise maintained. The Polylok lids are pre-installed with handles, which make it simple to remove the lid whenever you need to get access to the system or to replace it. The bottom of the lids is structurally supported, which allows them to remain relatively flat rather than domed in shape, as is the case with many other items on the market.

LARGE ADAPTER RING

An adapter ring is required in order to properly install septic tank risers on your septic tank. We have one of the largest adapter rings available on the market, allowing you to cover up to a 25″ square or 27″ circular aperture with a Polylok adapter ring. This ring fits both 20″ and 24″ risers, allowing you to have a great deal of versatility no matter what size your opening happens to be!

GET OUT YOUR MEASURING STICK!

A few measures must be taken before purchasing a septic tank riser system in order to ensure proper installation. The first thing to consider is the size of your opening. Take a measurement of the aperture in your septic tank at its widest point to determine the size of your tank. Instead than measuring the present lid, it’s critical to measure the opening. Because you will be removing the present cover, the measurements of the lid are no longer important and may differ from the size of the aperture itself.

The second measurement will be the distance between the top of the septic tank and the surface of the ground. You are now prepared to make a purchase based on these two measures!

THE COMPLETE RISER SYSTEM

We have a large selection of components from which you may pick to create your own own full riser system. Our many various options offer our product the adaptability to be utilized in virtually any application, but they may also be a bit daunting when attempting to pick which components to buy for a certain application. Each component is discussed in further depth below.

ADAPTER RINGS

The adapter ring is the first component that you’ll need to put together in order to assemble a full riser system. The adapter ring attaches directly to the septic tank, allowing the risers to stack, lock, and mount to it without the need for any additional hardware. Having this component is critical since the risers are not flat on the bottom because they are meant to be stackable, and it is not feasible to install them straight to the septic tank without this piece. The adapter ring provides the flat surface you need to mount to the tank while also being able to accommodate the stackable risers that are included with the tank.

Our square tank adapter ring can accommodate big square apertures up to 25 inches in diameter and large round openings up to 27 inches in diameter.

They are intended to be used with openings that are 24″ or less in diameter.

Concrete anchors, a masonry bit for installing the anchors, and butyl sealer are all included in this set.

RISERS

To construct a full riser system, the adapter ring is the first component that must be assembled. Stacking, locking, and mounting risers to the septic tank are all made possible by the adapter ring, which attaches directly to the septic tank. As a result of their design to be stackable, the risers do not have a flat bottom and so cannot be mounted directly to the septic tank, which makes this item critical. Using the adapter ring, you may install your tank on a level surface, while also accepting the stackable risers that are included with it.

We can accommodate big square holes up to 25 inches in diameter and large round openings up to 27 inches in diameter with our square tank adapter rings.

Alternative: We sell and strongly suggest our Adapter Ring Installation Kit, which we sell and highly recommend as well.

Concrete anchors, a masonry bit for installing the anchors, and butyl sealer are all included in this package. The use of this installation kit provides a strong mount as well as a proper seal between the adapter ring and the septic tank during installation.

OPTIONAL SAFETY SCREEN

In addition to the 20″ and 24″ riser systems, Polylok also produces safety screens that fit within the riser systems. These screens serve as a supplementary layer of protection in the event that the riser cover is unintentionally damaged or removed, and they keep foreign objects from entering the septic tank. They also keep dogs from slipping into unprotected septic tank openings!

RISER LIDS

You will require a lid to complete your riser system, which is the final component you will require. Both the 20″ and 24″ riser systems may be used with the Polylok lids, which are available in two different types to suit your needs. For ease of access, the basic lid is equipped with handles and a gasket that has been factory placed, as well as stainless steel screws to keep it in place. These lids are strong enough to withstand foot traffic as well as the weight of a riding lawn mower driving across them.

  1. Stainless steel screws are included for installation.
  2. Installations below grade or in regions with a high volume of foot traffic are advised for the heavy-duty lids.
  3. The shipping of these items in large boxes necessitates the addition of additional time, materials, and UPS shipping fees.
  4. If you place your order before 2 PM CST, you will be able to get your order sent the same day you placed it.

FREQUENTLY ASKED QUESTIONS

The following are some of the most commonly asked inquiries that our customer support representatives are asked. Take a peek below; it’s possible that the queries you have have been answered!

WILL THE LID FIT DIRECTLY ON THE ADAPTER RING OR DO I NEED TO USE A RISER?

With the exception of the 24″ Heavy Duty Lid, the lid will often fit straight onto the adapter rings in the majority of cases. The underside of the 24″ Heavy Duty Lid is strengthened for added strength. The height of this reinforcement is actually more than the height of the adapter ring. Therefore, the 24″ Heavy Duty Lid will only be able to be used without using an adapter when the opening is at least 24″ in diameter. The lid will not fit through any aperture less than 24 inches in diameter.

CAN I CUT THE RISER SYSTEM DOWN TO A SPECIFIC HEIGHT?

No, the Polylok riser system is available in increments of 6″ and 12″, and it cannot be customized to a certain height. Cutting the riser will result in the lid not being adequately secured on the riser that has been cut down.

DO I BRING THE RISER SYSTEM JUST BELOW, AT, OR ABOVE GRADE?

It is entirely up to you whether you want to bring the riser system up to grade, raise it above grade, or leave it slightly below grade. Because the riser system is airtight and watertight, there is no danger in moving it up to or above grade level.

SHOULD I USE THE STANDARD OR THE HEAVY DUTY LID?

The regular lid is sturdy enough to withstand foot activity and weights up to the weight of a small riding lawn mower passing over it without bending or breaking.

If the riser system is located in a high traffic location or is going to be run over by lawn equipment on a frequent basis, the heavy duty lid is recommended. If you have any more queries, please contact us at 1-877-925-5132 or [email protected]

Keep an eye out for a circular lid that is roughly two feet in diameter during your quest. Septic tank lids are normally constructed of green or black plastic, however they can occasionally be made of concrete. It is not always simple to locate the septic tank lid, however, because untidy vegetation, mud, or debris might obscure the lid’s location. If you live in a snowy climate, seek for a spot of lawn where the snow melts more quickly than it does anywhere else on the property.

How to Find Your Septic Tank Lid as a New Homeowner

During the process of purchasing your house, you should have been provided with a map of your property that showed the location of your septic tank. This is normally included as a part of your home inspection service package. All you have to do from there is compare the diagram to your land, find the septic tank location, and potentially dig around it to check whether the lid has been hidden by vegetation or other obstructions. People have been known to place an object such as a huge rock on top of the septic lid, so be sure to look beneath landscaping stones as well.

How to Find Your Septic Tank Lid as an Existing Homeowner

Still having trouble locating your septic tank lid? There’s a significant probability it’ll end up in the ground. The pipes coming from your basement should be followed, as they will take you in the direction of your septic system, which is what we propose. Then, once you’ve determined the correct direction, check for any high or low points in the yard that might reveal the location of your septic tank. You can find the lid of your septic tank by probing the ground with a metal probe every few feet with the probe.

Because most lids have a metal handle or fastener on them to hold the lid closed, you may also use a metal detector to find them.

The majority of lids are buried up to a foot deep, but some lids might be buried as deep as four feet in extreme cases! In some instances, a professional with specialized locating equipment may be required.

How to Maintain Your Septic Tank Lid

Following the discovery of your septic tank lid, keep it in good condition to avoid damage and ensure simple access for future septic tank maintenance, such as pumping your septic tank every three- to five-year period. Here are some pointers for keeping your septic tank lid in good working order:

  • Keeping the grass around the septic tank lid regularly mowed is important. Remove any dirt or debris that may have accumulated on your septic tank lid
  • Mark the area to ensure that no one parks or constructs structures there. It is possible to do this using a flag, garden décor, or ornamental pebbles.

Installing Access Risers

In order to perform fundamental septic system maintenance, you must first evaluate the condition of your septic tank and pump chamber (if you have one), which can be time-consuming and labor-intensive if you do not have access ports known as risers. Consider the prospect of having to dig through two feet of dirt to check the oil on your vehicle. Installing septic tank risers for an off-site septic system is broken down into four steps, which are outlined below. Please keep in mind that the currentWashington State Coderequiresrisers for all septic systems, which means you may be forced to install one if you are asking for a construction permit, land division, or any other type of official action in the state.

A few safety tips before you get started:

  • Struck by an underground electrical wire while excavating may be quite dangerous! If you are in any way doubtful about the presence of subterranean lines on your property, you can have them found by contacting 1-800-424-5555 or 811, or by visiting the website
  • Use the buddy system to your advantage! Working with a partner is usually recommended since the fumes connected with open sewage can be dangerous and cause a person to go unconscious. Never leave a septic tank that is open unattended! Once the lids have been removed, exercise caution around the tank and keep dogs and children at a safe distance. Examine the structural integrity of your septic tank! If a septic tank is more than 20 years old, it is recommended that it be pumped to ensure that the tank’s structural integrity and water-tightness are not compromised. Instead of spending money on costly repairs, it is preferable to replace the tank with a contemporary septic tank that includes risers as part of the installation. A permit from your local Environmental Health department is required for the replacement of a septic tank.

Gather all the MaterialsTools You will Need

It should be possible to get most of the components required to construct a septic tank riser at your local plumbing hardware store or on the internet. PVC risers are available in a variety of shapes and sizes. Some of the brand names you might be familiar with include “Tuf-Tite,” “Polylok,” and “Orenco.” Risers are typically 24 inches in diameter and may be readily inserted into the tank hole opening without difficulty. Due to the fact that certain tanks have square openings, it might be difficult to fit a riser around the square entrance.

Some types of risers are made to order based on the height you want, while others are available in increments of 6-12 inches.

Then purchase an Adapter and Risers that are somewhat bigger in diameter than the hole.

See below for Step 4 on attaching risers to the tank entrance. For the purpose of installing a riser system on your septic tank, you will require the following components:

  1. Tank Adapter Ring (TAR)
  2. Riser Adapter Ring Kit
  3. Butyl Rope
  4. Risers
  5. Domed Lid OR Flat Lid
  6. Stainless Steel Screws

The following materials will be required for digging up your septic tank(s):

  1. As-built condition of the sewage treatment system The following items are required: sketch on paper, measuring tape, shovel, probing instrument, eye protection, and work gloves.

To cut risers to the proper size, the following tools are required:

  1. Circular saws, saber/jig saws, and hand saws
  2. Raspor file
  3. Marking pen
  4. Tape measure
  5. Drill with a 1/4″ bit

Materials required to seal the risers to the tank include:

  1. High-strength concrete patch mix
  2. A small bucket
  3. A mixing stick
  4. And gloves

Follow the four simple procedures shown below to install access risers on your septic components, or download and print a copy of theSeptic Tank Manhole and Access Riser Installationbrochure from Thurston County Environmental Health to get started right now.

Step 1: LocateYour Septic Tank(s)

When looking for your underground septic tank or tanks, it is essential to consult the ‘As-built’ Record Drawing linked with your septic system for assistance. Essentially, this is a plot diagram that shows where your septic system was put on your property, as well as distances between septic components and notable landmarks. The Online Permit System will guide you through the process of locating septic-related documentation if you do not have a “as-built” document. It is possible that you may need to contact Environmental Health to examine the paper records or seek a specialist to find your tank if an as-built is not accessible.

Probing the area around the septic tank with the probing instrument until you contact concrete should be done lightly.

The presence of underground electricity or other utility lines and cables might put your septic tank in danger.

Call 1-800-424-5555 or 811 or go online to make sure that any electrical utilities are found before you begin digging before you begin digging.

Step 2: Uncover Your Septic Tank (s)

Once you’ve discovered your septic tank, you may start digging about. The tank is typically 6 feet wide by 8 feet long, with the width being the largest size. Remove all of the pebbles and debris from around the tank’s lid openings and dig out the whole top of the tank. You will want to clean out any dirt that has accumulated on the surface of your septic tank. This will assist you in ensuring that you generate a high-quality seal. You should have two openings: one over the inlet (which comes from the home) and another over the outlet (which comes from the yard) (into the drainfield or pump chamber).

  • You’ll need a riser for each of the doors you open.
  • Typically, the inlet side is the one that is nearest to the home.
  • When cleaning the tank, it is beneficial to remove the complete top of the tank.
  • Risers must be modified in order to be correctly installed, and all manholes (holes 24 inches or bigger in diameter or square in shape) must also be updated, as well as the tankinlet and outlet baffle covers (if separate from the manholes).
  • If you discover one – and only one – riser already installed, it is most likely for the pump chamber, which only requires a single riser to provide access to the pump to function properly.
  • Remove the concrete lids so that they may be disposed when the project is completed.
  • Consult your’As-built’Recorddrawing to establish whether you have a distribution box (D-box), which you will also need to unearth and place a riser on if you have a typical gravity system.
  • Once the lids have been removed, proceed with caution around the tank.
  • Inform someone of your whereabouts in case you are involved in an accident.

You should be aware that exposure to sewage can result in serious sickness, so make sure you wear gloves and thoroughly wash your hands afterward with soap and water. It is also recommended that you wear eye protection in the event that debris falls into a tank and splashes back at you.

Step 3: Fit Risers to Component Openings

In accordance with the diameter of the septic tank manholes, huge risers will either sit on top of the septic tank or will fit down into the aperture of the tank by 1-3 inches. It’s important to keep this in mind while calculating the height of the riser. The surplus can be easily removed; nevertheless, it is difficult to add a few inches to the length. Take the following measurements of the manhole cover’s diameter:

  • Theriser will fit into the tank hole if the aperture is between 26 and 29 inches in diameter. Measure the distance from the ground to the top of the septic tank and multiply the measurement by three inches. The following is required if the aperture is greater than 29 inches: a 3-foot square fiberglass plate (with a 22-inch hole in the middle) is required. In this case, it lies above the manhole and narrows the aperture, allowing a 24-inch riser to be utilized instead of a more expensive 30-inch riser, saving money.

The distance between the ground and the top of the fiberglass plate should be measured. You may choose to place the risers so that they are level with the surface of the ground, or you may want them to stand out a few inches above the ground (if a riser is above ground make sure you are careful when mowing). Tips: To shorten a big riser with ribs, drill a 1/4-inch hole between the ribs above the cut line and finish the cut by following one of the grooves between the ribs with a saber/jig saw to finish the cut.

By eliminating one of the ribs from the largeriser, it may be made to fit more snugly into a smaller manhole entrance.

Step 4: Attach Risers toSeptic Tank (s)

It is recommended to pump out an old septic tank that is 20 years or older in order to check its structural integrity and water-tightness before using it again. If the tank requires extensive repairs, it is preferable to replace it with a new septic tank that includes risers as part of the installation. A permit from the local health department is required for the replacement of a septic tank. Remove any dirt and debris from the tank’s surface by cleaning it off. Using the butyl rope, construct the components of the risers in accordance with the manufacturer’s instructions.

Jet-Set, Rapid-Set, Thorough-Set, and Perco-Plug are just a few of the brand names available.

NOTE: For optimal results, just a little amount of concrete patch should be mixed at a time.

The patch mix should be used to seal the riser to the septic tank.

If you want to avoid a safety danger, make sure you properly attach theriser lid using the screws that come with it!

Risers for inlet or outlet apertures that are smaller than the openings should have the bottom few inches sanded with rough sandpaper to allow a firmer connection between the two surfaces.

A useful source of information on correct installation of risers on septic tanks may be found at your local hardware store where you purchased the risers and covers.

Thurston County Environmental Health is should be commended for providing the foundation for this documentation.
