How To Attach Pvc Septic Tank Riser To Concrete Tank Lid? (Best solution)

  • Expose enough space, approximately 2 feet in all directions, to allow room for the installer to move freely. Remove the existing lid on the septic tank. Install an adapter ring in the opening to the septic tank. The risers will attach directly to this ring. Secure the ring to the tank by using concrete.

How do you secure a septic tank lid?

Keep the lids secure by repairing or replacing all damaged or missing parts. Use bolts, screws, or other locks to secure the lids and prevent easy access. Never drive or park vehicles on top of septic systems – it can damage or dislodge the cover.

Should I install a riser on my septic tank?

Having a riser in place can also significantly reduce the cost of septic tank maintenance over time through the ease of access and time on the job saved. Plus you will be spared digging up your lawn every time as well.

How do you seal a septic riser?

Seal the riser to the septic tank using the patch mix. You may finish sealing by adding Bentonite or casing sealer around the base, filling in gaps as needed. Make sure you then carefully secure the riser lid with the screws provided to avoid a safety hazard! All risers must be completely sealed to the septic tank.

Where is the lid on a concrete septic tank?

You can locate the lid of your septic tank by poking the ground every few feet with a metal probe. Lids can be buried up to a foot deep on average, so be sure to investigate any bumps that may indicate something is buried underneath.

Do they make square risers for septic tanks?

The Polylok square riser adapter ring is designed to connect the Polylok septic tank risers or lids to an existing concrete tank with large square or round openings.

Is it OK to cover septic tank lids?

If you have a traditional septic system, the tank should be pumped every 3-5 years. That means that the septic lids should be accessible every 3-5 years. You can use almost any temporary, movable objects to cover your lids, like: Mulch (but not landscaping)

Should septic tank lids be buried?

In most cases, all components of the septic tank including the lid are buried between 4 inches and 4 feet underground. Unless the septic tank has special risers that position the lid at ground level, you’ll have to dig for it.

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.

  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.

If you run into a power line, the consequences could be fatal. 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.

  1. Jet-Set, Rapid-Set, Thorough-Set, and Perco-Plug are just a few of the brand names available.
  2. NOTE: For optimal results, just a little amount of concrete patch should be mixed at a time.
  3. The patch mix should be used to seal the riser to the septic tank.
  4. If you want to avoid a safety danger, make sure you properly attach theriser lid using the screws that come with it!
  5. 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.
  6. 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.

How to Install Septic Tank Risers

A septic-tank riser is a pipe that goes from a septic tank to the surface in order to raise the tank’s lid. Installation of these low-cost devices eliminates the need to dig in order to reach the tank’s lid for inspection or maintenance purposes, saving you time and money. To place risers on your tank without needing to employ a professional, simply follow these instructions.

Step 1 – Choose the Material

The materials used to make risers include concrete, polyvinyl chloride (PVC), and polyethylene. Concrete is the most common material utilized. The pricing, durability, and convenience of installation of these three materials are all different. Even while concrete is the most inexpensive material, it is also the most difficult to install due to its weight. Risers made of polyethylene are lighter and quicker to install, and they are more resistant to soil erosion than steel risers. They are, however, more susceptible to gas and water leaks than other alternatives.

This material is not only simple to install, but it also does not readily leak water or gas when exposed to extreme temperatures.

Step 2 – Decide Where to Install the Risers

Risers are used to replace the lid of the septic tank and to bring access to the tank closer to the ground’s surface. This access can be installed above ground, where the risers are clearly visible, or it can be installed just below the surface, where the risers are not visible. Typically, above-ground installation is employed in regions that are neither visible nor interfere with grass maintenance procedures. Installing risers above ground also allows you to reach the tank conveniently. The risers, on the other hand, are hidden beneath the surface of the earth in a below-ground installation.

Step 3 – Determine the Height

Septic tanks can be buried as far as three feet below the surface of the ground, although the typical depth is 18 inches, according to the EPA. Risers are available in two different heights: 6 inches and 12 inches. They are built on top of one another until they reach the surface or come to a halt just below the surface of the water. Measure the distance between the tank and the location where the new lid will be put in order to calculate the number of risers that will be required.

Step 4 – Gain Access to the Septic-Tank Lid

In order to install risers, you must first dig down to the septic tank’s lid in order to obtain access to the tank. Allow ample space, roughly 2 feet in all directions, for the installer to be able to move around without being obstructed.

Step 5 – Install an Adapter Ring

Remove the current septic tank cover from its position. Make use of an adapter ring to seal up the entry to the septic system. All of the risers will be attached to this ring at the same time. Concrete is used to hold the ring to the tank in place.

Step 6 – Install the Risers

Install as many risers as necessary to attain the requisite height for an above- or below-ground installation, depending on the situation.

Screwing the risers together will allow them to be connected to one another. The fact that they are screwed together makes them watertight and airtight. It is simple to repair a septic-tank riser if one is ever damaged or destroyed.

Step 7 – Install a New Lid

Lids are available in a variety of sizes. Select a lid based on the size of the risers that you want to use. Installation Instructions: Place it on top of the final riser and fasten it using the two pins that are included.

How to Replace a Concrete Septic Lid With a Plastic Lid

Jupiterimages/ Images is the source of this image. In most cases, thick concrete lids over manholes and access holes are used to build concrete septic tanks, which are subsequently covered with soil after installation. While this is a satisfactory installation, many septic specialists recommend that the concrete lids be replaced with plastic risers and lids to provide for easier access to the tank for examining and cleaning the system. The new plastic top is now easily accessible for pumping and maintenance thanks to the addition of a riser.

How to Replace a Concrete Septic Lid With a Plastic Lid

Remove any furniture, potted plants, yard décor, and other things from the surrounding area. Protect your pets, and keep other people and children away from the area. Put on your protective gear as well, such as gloves and safety goggles. When working with concrete, always use a dust mask or a respirator to protect your lungs from the silicates in the dry mix that can cause irritation.

Step 2: Locate the Tank and Lids

Identify the tank and its covers. As a result of the shallower soil and reduced ability to hold moisture for the lawn’s roots, dead grass may be an indication of the tank’s position. A metal detector may be used to discover rebar in concrete tanks, after which it can be probed to locate the edges.

Step 3: Remove the Soil

Remove all of the dirt that has accumulated on top of the septic tank. In most cases, the tank is located between 1 and 3 feet below the surface of the earth and up to 25 feet away from the home, depending on the conditions. When it comes to dimensions, the typical septic tank is around 4 1/2 feet broad and 8 feet long; however, larger tanks are available. Check for structural damage to the tank as well; cracks or a drooping top signal that repairs or replacement of the tank are necessary.

Step 4: Measure the Lid

Take the diameter of the lids, as well as any tank inlet or baffle outlet covers, and round them up. If the bigger lid, sometimes known as a “manhole” lid, has a diameter greater than 24 inches, it may be necessary to use an adapter before placing the lid riser over the hole. Adapters are available from the company that makes the lid riser.

Step 5: Remove the Lid

Remove the concrete covers from the containers and set them aside. Because the concrete lids are so heavy, it may be necessary to utilize a backhoe to complete this task. It is best not to breathe any of the fumes that are rising from the septic tank and to use a protective mask or respirator to minimize exposure.

Step 6: Adjust the Riser Height

Obtain an accurate measurement of the distance between the tank and the ground. Make any required adjustments to the riser in accordance with the manufacturer’s instructions, or in older systems, consider installing a riser to raise the new lid to ground level.

The present riser’s height can be reduced by drilling an appropriately sized hole in it and then trimming the surplus riser length using a jigsaw, as shown in the image below. Some manufacturers create adjustable risers, which eliminates the need for cutting.

Step 7: Rough the Riser Base

Using 40- to 60-grit sandpaper, sand the area around the base of the risers. Place the risers over the manholes, as well as the intake and outflow holes, after wiping them down with a tack cloth.

Step 8: Apply Concrete Patch Mix

In a bucket, combine the quick-drying, high-strength, flexible concrete repair mix that has been advised. Work rapidly, since the mixture will dry in 15 to 20 minutes if left to sit. With a trowel, apply a generous amount of sealant around the bases of the risers, being sure to cover the edges all the way up to the top of the septic tank. Allow for a thorough drying time.

Step 9: Attach the New Lid

Set replacement lids on the risers, following the manufacturer’s instructions and using a socket wrench to secure them in place.

Step 10: Rebury the Tank

Soil should be used to cover the septic tank. Cover the bare soil with sod or grass seed to prevent it from becoming naked.


  • Inspect and pump the tank (if necessary) while the lids are off
  • This will save you time and money later on. After finishing the activity, thoroughly wash your hands and clothing with soap and hot water to remove any remaining dirt.


  • You should never enter or even put your head inside a septic tank unless absolutely necessary. Every year, a number of people die as a result of the fumes produced by septic tanks
  • You may pass out, fall in, and suffocate or drown. When the lids of the septic tank are open, never leave the tank alone, even for a single minute. It is possible for a kid or pet to fall in and drown
  • Avoid driving over the risers and lids.

Septic Tank – adding riser to concrete lid
Author:kratman (GA)Question from homeowner on addingrisers to a concrete lid. I have a concrete tank (estimated at 1,500 gals, circa late 70’s) and the top is about 3 feet below ground level. The lid is composed of a series on concrete “planks” that are the width of the tank long and about 2.5 feet wide. So the planks sit laterally on top of the tank to form the lid. I am unsure how many planks are in total (since the entire lid was not exposed when it was recently pumped), but I would guess four planks total.Since the lid is so deep and pumping it made a real mess in my side yard from digging the area to expose the first plank, I wanted to add risers. The septic company wanted $1,500 to add two risers at both ends; but I wanted to explore some options. How does one add a riser to the plank units? Or would I go about getting this manufactured (precast company, etc)? I would guess the entire plank is replaced, but since they are only 2.5 wide, the riser diameter presents a problem. Thank in advance.

Re: Septic Tank – adding riser to concrete lid
Author:KCRoto (MO)Don’t take this wrong- I highly recommend having a riser installed to allow access to the tank.That being said, I don’t think that the average homeowner is up to the task of installing it.There are several factors in play.You need to have a riser that is larger than the current lid or has the same inside diameter as the opening you have currently.Then you need to consider the amount of weight that you are adding to the rim of the current opening.If you are adding too much weight, you could cause it to cave in.Also consider the weight of the riser itself when you would be installing it.Do you have the capability to set it properly?If you can handle the challenge, then I suggest contacting a local concrete vault or fabrication company; they can get you what you need as far as a riser and new tank lid.This forum isn’t for pricing, but I can tell you that in my opinion, adding risers, lids, and installation to two spots doesn’t seem unrealistic.

Re: Septic Tank – adding riser to concrete lid
Author:sharp1 (IL)The weight of the new lid and risers will be less than the weight of the 3′ of dirt removed. The company that cast the original tank and lid is probably in your area if still in business.

Re: Septic Tank – adding riser to concrete lid
Author:hj (AZ)Usually, the two end sections have “square” access openings above the baffles. if so, a section of 6″ ABS or PVC will cement into the opening with female adapters and plugs on top.

Re: Septic Tank – adding riser to concrete lid
Author:KCRoto (MO)Unless you installed it, you are making it up as you go.Septic tanks aren’t made to specific dimensions anywhere.I have seen concrete in varying sizes, shapes, and thicknesses. I have found them made of clay, steel, and plastic.Every concrete vault manufacturer has its own design, lid size, and placement.

Re: Septic Tank – adding riser to concrete lid
Author:Wheelchair (IL)I can tell you what I did.It worked for us.Our septic tank was 1200 gallon and concrete. We had 3 slabs, each having 2 loops of re-bar for lifting them.Each slab was about 3 ft x 5 ft and were laid side by side.I did exactly what you want to do.I made a frame using 2 X4 and plywood under.I was able to obtain a 3 ft piece of 20 inch PVC pipe.I secured the pvc inside of the form and secure everything with rows of re-bar.I oiled all of the wood and used plastic bags as a liner to keep the concrete off the forms.My neighbor was pouring a slab of concrete in his drive was and he had some extra material.3 wheel barrels and I pour the concrete into my form. I added 2 hook loops and let the concrete dry for 3 days before I removed the forms. The slab with the 3 ft stack was lifted and place on the edge of the septic tank.We back filled with dirt and sand to compact the area to almost the top of the stack.I went to a specality shop that sold septic system supplies.Only then did I realize that the industry made 4 inch x 22 inch, stackable flange pieces that snapped together to form any height.I purchased a 22 inch dome cover and placed it over the 20 inch pvc pipe.It worked perfectly and allowed me to add an additional 3-4 inches of dirt over the cover. No one walks on the cover.Removing 3-4 of dirt is a lot easier to do and repair.I’m happy and that was over 3 years ago.That’s 3 snowy winters.Best Wishes

Re: Septic Tank – adding riser to concrete lid
Author:hj (AZ)Maybe so where you are, but here, almost EVERY tank, regardless of who made it has an access port above the baffles. They also usually have a large center port, but no one installs a riser at that one.

Thanks to all
Author:kratman (GA)ok Thanks. All good ideas. I had thought about pouring the lid myself, and may do that. But I will speak to a tank manufacturer in the area first.I have not checked the middle of the tank for an existing access hole but will do that as well. 3 feet of Georgia clay is not much fun. Thanks. Kratman.Edited 1 times.

How To Instal Risers On A Septic Tank

A septic tank riser system will be installed today, and we will demonstrate how to do it. If you have a concrete septic tank that does not have risers built, this instruction is for you. It is currently mandatory in many areas to have risers and lids installed on your septic tank. When it comes time to have your septic system pumped out, installing a riser system can also save you money. Please follow the instructions in the following section and you will have no difficulties.

Step 1 – Gather The Parts You Need

The following things will be required for the installation of a riser system on your septic tank. (Click on the item to make a purchase.) Tuf-Tite Tank Adapter Ring (optional) (TAR) 2)Riser Adapter Rings Kit (includes riser adapter rings) Butyl Rope (number three) Tip-Tite Risers are a type of tie-down device. 5)Tuf-Tite Domed Lid (optional). ORTuf-Tite Flat Lid (Ortuf-Tite Flat Lid) 6) Screws made of stainless steel Keep in mind that you will have to determine the size of the hole in your septic tank.

Consider this: If the hole in your septic system is 22 inches across at its widest point, you will need to purchase the 24 inch Tank Adapter Ring, 24 inch Risers, and 24 inch Lid.

Step 2 – Clean The Top Of Your Septic Tank

You will want to clean out any dirt that has accumulated on the surface of your septic tank. In doing so, you will increase the likelihood of successfully creating a good seal. A concrete ring is seen on the left side of the image. Using this as an example, we will illustrate how to install a riser system. In order to offer a visual picture of a hole in a concrete septic tank, the following image was created. The diameter of this one is 16 inches. It is possible that your hole is bigger or smaller.

Remember to measure the hole diagonally before purchasing the appropriate Tuf-Tite Tank Adapter Ring.

Step 3 – Apply Butyl Rope To Tank Adapter Ring

To secure your Tuf-Tite Tank Adapter ring to the bottom of your tank, tie a butyl rope ring around it.

This will aid in the creation of a water-tight seal. Make sure the butyl stretches all the way around the Adapter Ring before you tighten it.

Step 4 – Put Adapter Ring Around Hole And Screw It Down

Firmly push the Tuf-Tite Tank Adapter Ring onto the septic tank’s adapter ring to secure it. To begin drilling the holes, use the drill bit that included with the package. The Adapter Ring will have divots in the areas where the holes will be located. Once you have pre-drilled the holes, you may use the blue concrete tapping screws that are provided to secure the ring to the top of your installation system.

Step 5 – Add Butyl Rope To The Bottom Of Each Riser

The bottom of each riser will have a recessed ring in the center. In this ring, insert a strip of butyl rope and tighten it. This will ensure that the risers are watertight.

Step 6 – Put Risers and Lids On The Adapter Ring

Now it’s time to attach your risers to your Adapter Ring. Their installation will be accomplished by screwing them into place using stainless steel screws. In order to raise it to the proper height, you can use as many risers as necessary. That’s all there is to it. You have completed the installation of a riser system on your septic tank, which should pass inspection anyplace in the United States of America.

How do you install a concrete riser on a septic tank?

Installing Risers in a Septic Tank is a simple process.

  1. Step 1 – Collect the components you’ll need
  2. Step 2 – Vacuum the top of your septic tank
  3. And Step 3: Attach the Butyl Rope to the Tank Adapter Ring. 4. Insert the adapter ring around the hole and tighten it down. Then, in Step 6, attach the Risers and Lids to the Adapter Ring with Butyl Rope at the bottom of eachRiser.

It is possible to gain access to your septic tank from the ground level by installing an access shaft that runs from the top of the tank down to the ground level. Ariserwill cost you around $300 to $400 to install, but it will be well worth the investment to provide maintenance crews quick access should it require repairs or maintenance. Also How many risers should a septic tank have, do you know? This is a must-have if you want to get to your septic tank quickly for maintenance. First, I attached a 24 x 12tank riser first, then a second 24 x 6tank riserfor more height, and lastly a 24 inch flat lid.

You’ll never have to dig yourself out of a hole again.

Here are some basic procedures to take to replace the septic tank riser so that you may continue to locate the lid with ease.

  1. Step 1: Dig out the old Risers
  2. Step 2: Excavate the area around the Risers
  3. Step 3: Remove the Riser Lid
  4. Step 4: Remove the Risers
  5. Step 5: Remove the Ring if it is damaged
  6. Step 6: Stack the Risers
  7. Step 7: Add the Rider Lid
  8. Step 8: Backfill the soil.

What is a septic system riser and how does it work? The riser of an aseptic tank is a concrete or plastic pipe that extends vertically from the pump-out holes or access ports at the top of the tank to about ground level. Despite being a straightforward and seemingly common sense notion, risers are frequently absent from typical septic tanks, especially older types.

What You Should Know About Septic Tank Risers

Septic tank risers are an important part of any septic system, and they should be installed in every property. This article will provide you an overview of septic tank risers and how they may help your septic system. What Is the Function of a Septic Tank Riser? A septic tank riser is a conduit that connects your home’s surface drainage system to your septic tank beneath the ground level. An access port or the pump-out ports on the septic tank are where the riser connects to the tank. Septic tank risers are equipped with lids that can be quickly removed to allow you to check or pump your septic tank without having to dig up your yard.

  • These structures are often made of materials that disintegrate slowly over time, such as plastic or concrete.
  • What Are the Advantages of Using Risers?
  • Normally, this entails digging up your yard before the pump is installed and reburying the tank once it has been installed.
  • The use of a septic tank riser can help to minimize the amount of time spent pumping your septic tank.
  • The fact that the riser is visible above the surface of your yard makes it an ideal signal for locating your septic tank the first time you need to discover one in your yard.
  • For those who want to stay in their house for several years, septic tank risers are not only handy, but they are also cost-effective.
  • Concrete risers are more durable, but they are also more expensive, and the price will be determined by the quote you receive from the contractor who will be installing them.

What Is a Septic Tank Riser?

As the name implies, it is a long, robust pipe made of plastic or concrete that connects your septic tank, which is located deep below, with the surface of your lawn. The riser is connected to the septic tank by an access port or a pumping aperture in the tank’s wall. For inspection, maintenance, and pumping, risers have lids that can be opened without digging up your yard. This avoids the need to dig up your yard.

The Benefits: How Septic Risers Save You Money

As a rule of thumb, septic system manufacturers recommend that you examine your septic tank once a year and pump your septic tank every three to five years. However, if your septic system is not equipped with a riser, you may be forced to pay additional fees.

No Digging Fees

You or your septic tank specialist will have to spend time and money digging through the earth to locate your tank if you or he does not know the precise position of your tank. Your septic tank will need to be recovered with earth once it has been serviced and pumped without a riser, and they will need to do this every time they service your septic tank going forward.

Reduces Labor Costs

Incorporating an easily visible septic tank riser makes it easier for the contractor to access the riser lid, insert the pump hose, and start to work more quickly and efficiently. In this case, they may leave their heavy equipment at home, which saves you from having to spend a large amount of money in labor.

You’ll Only Pay for Materials and Labor Once

When you have a septic tank riser installed, you will only be responsible for the labor and materials used in the installation. The money you save on yearly inspections and regular local maintenance will more than compensate for the cost of the septic tank riser over time.
