Benefits of Using a Septic Tank Riser Kit

Installing a septic tank riser kit can extend the life of your system and make maintenance much easier. Risers provide accessibility to the top of your septic tank, help reduce water infiltration into your soil, and help maintain proper levels of aerobic bacteria in your system.

What is a Septic Tank Riser?

A septic tank riser is a vertical pipe that extends from the top of a septic tank to ground level, making it easier to access the tank for inspection and maintenance. The height of the riser can range from 18-24 inches, depending on the size and type of septic tank you have.

Improved Baffle System and Inspection Access

One of the most significant advantages of installing a septic tank riser kit is improved access to your baffle system and inspection. This will make it much easier to assess and maintain the condition of your baffles, plus provide easy access for repair and cleaning when needed. It also allows for quick visual inspections every few years, which can help to identify potential problems before they become serious issues.

Clearer Hydraulic Profile

The presence of a riser kit on your septic tank can also help to improve the hydraulic profile of your system. By helping to regulate and refine water flow, it can support better nutrient removal which is essential for long-term drain field sustainability. Additionally, installing a septic tank riser can allow for deeper cleaning of the infiltration bedding material. This ensures that your baffles don’t become clogged with silt or sediment and can help reduce the overall maintenance costs associated with your property.

Easier Manhole Cover Replacement and Maintenance of the Tank Lid

Installing a septic tank riser can make it much easier to replace the manhole cover and check the condition of the septic tank lid. This is because a riser will raise the manhole and lids closer to ground level, making it much easier to access them for inspection and maintenance. This can save you time and money in the long run and ensure that your system remains working in optimal condition.

Minor Septic System Repairs Can Be Done Without Digging Up the Tank

With a septic tank riser kit, you don’t have to worry about digging up your septic system in order to do minor repairs. By having the lid and manhole cover at an easier-to-access level, you can save time and money by avoiding the need to dig up your entire tank. This provides an added benefit of saving you the disruption caused by needing to excavate your tank just for replacing or inspecting lids or covers.

Increased Efficiency and Durability of Septic Systems Over Time

Installing a septic tank riser kit increases the efficiency and durability of your septic system over time. With the lid and manhole cover at an easily-accessible level, you avoid damage to underground piping during repair or replacement work. Additionally, it delays maintenance or repair work by giving you a better view of what’s going on inside of your tank, making it easier to identify any potential problems before they become serious.
