Can I DIY Install a Septic Riser?

Yes, you can install a septic riser yourself if you have the right tools, knowledge, and some basic DIY skills. However, installing a septic riser properly is essential to ensure your system functions efficiently and remains accessible for maintenance.

While the installation can be relatively straightforward, there are certain steps and precautions that need to be followed to ensure a successful DIY installation.

Step-by-Step Guide to DIY Septic Riser Installation

1. Locate the Septic Tank

The first step in installing a riser is to locate your septic tank and the access lid. If you don’t know where it is, you may need to check with your local health department for the system layout or hire a professional to help you locate it.

Be prepared to dig down to expose the septic tank lid.

  • Tip: The septic tank is usually located about 1-3 feet underground, so you’ll need a shovel or digging equipment to access it.

2. Measure the Depth

Once the lid of the septic tank is exposed, measure the distance from the top of the tank to the ground level. This will help you determine the height of the riser you need to install.

  • Tip: Septic risers typically come in sections, allowing you to adjust the height based on the depth of the septic tank.

3. Choose the Right Riser and Cover

Septic risers are available in different materials, such as polyethylene, fiberglass, and concrete. Choose a material that fits your budget and needs, but remember that lightweight materials like polyethylene and fiberglass are easier to install and maintain.

  • Riser Types:
    • Polyethylene: Lightweight, durable, and easy to install.
    • Fiberglass: Stronger than polyethylene, but more expensive.
    • Concrete: Heavy-duty, but challenging to install without assistance.
  • Cover Options:
    • Ensure the cover is durable, weather-resistant, and has a secure locking mechanism to prevent unauthorized access.

4. Remove the Old Lid

If you are retrofitting a riser onto an older system, you will need to remove the existing septic tank lid. Carefully lift and set it aside.

  • Tip: If the old lid is cracked or damaged, it’s a good idea to replace it with a new one to ensure a secure seal.

5. Attach the Riser to the Tank

Most septic risers are designed to bolt directly to the septic tank. Follow these steps to ensure a secure attachment:

  • Clean the surface of the tank opening to ensure a tight seal.
  • Apply a sealant (such as butyl tape or a silicone-based adhesive) around the lip of the tank opening to create a watertight seal.
  • Place the riser on the opening and secure it with bolts or screws, ensuring it’s firmly attached to the tank.
  • Tip: Make sure the riser is level to ensure the cover fits properly.

6. Install the Riser Sections

If you need to extend the height of the riser, stack additional riser sections on top of each other until the riser reaches ground level. Each section should fit snugly and be sealed with a watertight gasket or sealant to prevent water infiltration.

7. Attach the Riser Cover

Once the riser is installed, attach the cover. Most covers come with screws or bolts to secure them in place, ensuring they won’t shift or be removed accidentally.

  • Tip: Use a cover with a locking mechanism or tamper-proof screws to prevent unauthorized access, especially if you have children or pets.

8. Backfill and Finish

Once the riser and cover are securely in place, backfill the area around the riser with soil. Make sure the top of the riser is slightly above ground level for easy access, but not so high that it becomes an obstruction in your yard.

  • Tip: Tamp down the soil to ensure stability and even out the area around the riser.

Pros and Cons of DIY Septic Riser Installation

Pros:

  • Cost Savings: Installing a septic riser yourself can save on labor costs, which can range from $200 to $500 for professional installation.
  • Convenience: A riser brings the access point to ground level, eliminating the need for future digging when your septic system needs to be pumped or inspected.
  • Customization: You can choose the materials and height that best fit your needs.

Cons:

  • Labor Intensive: If your septic tank is deeply buried, digging down to the access point can be time-consuming and physically demanding.
  • Risk of Improper Installation: Improper sealing or attachment of the riser could result in leaks, water infiltration, or system inefficiency.
  • Heavy Materials: If you choose a concrete riser, the weight of the material may require extra help or equipment to install.

When to Call a Professional

While DIY septic riser installation can be a great way to save money, there are some situations where it’s better to call a professional:

  • Difficult Access: If the septic tank is deeply buried or difficult to access, professional equipment may be needed.
  • Damage to the Tank: If you notice cracks or damage to the septic tank during installation, it’s best to have a professional inspect and repair it.
  • Complex Systems: For homes with larger or more complex septic systems, professional installation may be safer and more efficient.

Conclusion

DIY septic riser installation can be a cost-effective way to improve access to your septic system. With the right materials and careful attention to the installation process, you can ensure that your system is easier to maintain while protecting your yard from future disruptions. However, if your tank is deeply buried or you encounter complications, don’t hesitate to seek professional help to ensure the job is done correctly.
