How to Install a Septic Tank Riser Guide

Need to install a septic tank riser? If you own a home with a septic system, you know maintenance isn’t optional. One way to make regular upkeep easier is by installing a septic tank riser. At 1 Source, we specialize in septic installation and repair, and we recommend risers to almost every homeowner with a buried tank. 

Here’s what you need to know about septic tank risers, when to install one, and how to do it right –

What Is a Septic Tank Riser?

A septic tank riser is a durable pipe that extends from the access port of your underground septic tank up to ground level. It creates a direct, easily accessible entry point to your tank, so you (or your service provider) don’t need to dig every time you pump, inspect, or maintain the system.

Risers are typically made from plastic (like HDPE or PVC), concrete, or fiberglass. Each material has pros and cons in terms of cost, weight, and longevity, but plastic and fiberglass are most common today because they’re lightweight, corrosion-resistant, and easy to work with.

How to Install a Septic Tank Riser Step-By-Step:

Installing a septic tank riser isn’t overly complex, but it does require some tools, proper measurements, and attention to detail. If you’re not comfortable handling it yourself, call a professional. But if you’re a DIY homeowner, here’s a step-by-step guide –

Step 1: Locate the Septic Tank Lid

Use a probe rod or your septic system diagram to find the lid. You may need to dig it out.

Step 2: Measure and Choose the Right Septic Tank Riser Kit

Measure the diameter of your tank opening and how deep it sits below ground. Purchase a riser kit that includes the riser pipe, adapter ring, sealant, and lid.

Step 3: Clean and Prep the Tank Opening

Thoroughly clean the tank opening. Remove any dirt, debris, and loose concrete to ensure a good seal.

Step 4: Install the Adapter Ring

Secure the adapter ring to the tank opening using the included hardware or a strong epoxy, depending on the type of septic tank riser kit you have. Make sure it’s level.

Step 5: Attach the Septic Tank Riser

Connect the riser pipe to the adapter ring. Most septic tank riser kits use a screw-on or snap-in system. Apply sealant or gaskets as instructed to ensure a watertight fit.

Step 6: Secure the Septic Tank Lid

Attach the lid to the top of the riser. Most lids include a locking mechanism or bolts for safety. Make sure it sits flush with the ground to avoid trip hazards.

Step 7: Backfill Soil Around the Septic Riser

Carefully replace the soil around the riser, compacting it gently to avoid shifting. Leave the lid exposed at ground level.

Pro Tips:

• Consider insulating the riser if you live in a cold climate to prevent freezing.
• Choose a green or brown lid to blend with your yard.
• Mark the riser’s location on your property map for future reference.

Why Install a Septic Tank Riser?

If your septic tank lid is buried under several inches or feet of soil, a riser can save you time, money, and hassle. Here’s why you should consider adding one:

• Easy access for maintenance: No more digging to find the lid.
• Lower maintenance costs: Service providers charge less when no digging is required.
• Better system oversight: You can check the tank more often for signs of septic issues.
• Safety: A sealed riser with a locking lid is safer than an exposed or damaged tank cover.

When Do You Need a Septic Riser?

You should install a riser if your septic tank lid is more than a few inches below the surface. This is especially important if:

• You have an older system without easy access.
• You live in a rural area where digging can be more labor-intensive.
• Your property has hard or rocky soil.
• You’re planning to sell the home and want to make it more buyer-friendly.

When to Call a Septic Tank Installation Expert

While installing a riser is a straightforward project for many homeowners, there are situations where calling a professional is the smart move:

• You can’t locate the tank lid: If it’s buried deep or your system layout is unclear, pros can locate it with minimal damage.

• The tank or access port is damaged: Installing a riser on a cracked or worn-out tank lid requires expert handling.

• The job requires concrete cutting: Some older systems may need specialized tools or safety precautions.

• You want a watertight seal guaranteed: Professionals ensure proper sealing to avoid odor leaks and water intrusion.

• You’d rather not risk it: If you’re unsure at any point, having it done right the first time saves you money and headaches.
