Understanding Septic Tank Risers
What is a Septic Tank Riser?
A septic tank riser is a vertical pipe or structure that connects the septic tank to the surface ground level. Its primary purpose is to elevate the septic tank opening, providing direct access for maintenance, inspections, and pumping without requiring extensive excavation.
By bringing the access point to the surface, risers improve the functionality and efficiency of the septic system, making routine checks simpler and more convenient for homeowners.
Types of Risers
Septic tank risers are commonly made from plastic (PVC or polyethylene) and concrete. Plastic risers are lightweight, corrosion-resistant, and often easier to handle during installation.
However, they may be less durable than their concrete counterparts, which are heavy, sturdy, and resistant to damage but can be more challenging to install.
Riser Height Considerations
When selecting the appropriate riser height, it is essential to consider the depth of the septic tank and how much of the riser will be above ground. A riser should typically extend a few inches above the ground to prevent water accumulation while still aligning with local regulations and ensuring easy access for maintenance.
Preparing for Installation
Step 1: Locate the Septic Tank Lid
Before you start digging, locating the septic tank lid accurately is crucial. This may require you to consult your property records, as some tanks are buried deeply and not easily visible. If you’re unsure of the tank’s location, consider hiring a professional locator service.
Always prioritize safety by contacting your local utility services to mark any underground lines—this will help prevent accidental damage to existing piping or electrical systems during your excavation.
Step 2: Excavate Around the Tank
Once you have identified the location of the septic tank lid, use a shovel or excavator to carefully dig around the area. Make sure to create a generous space—at least three feet around the lid—to ensure comfortable access for installation.
As you dig, proceed with caution to avoid damaging the tank itself or any associated pipes. If you encounter roots or other obstacles, assess your approach to avoid complications; patience is key to a successful excavation.
Step 3: Clean the Tank Lid Area
After excavation, it’s essential to clean the surface around the tank lid thoroughly. Remove any dirt, debris, and remnants of old sealant to ensure a proper seal when installing the riser.
A clean surface will help prevent leakage and potential groundwater infiltration issues, contributing to your septic system’s overall longevity and functionality. Inspect the tank lid for any visible damage or wear that may need addressing before proceeding with the installation.
How to Install a Riser on Septic Tank: Installing the Riser
Step 1: Attach the Riser Base or Adapter
To begin the installation, carefully position the riser base or adapter over the existing septic tank lid. Ensure that the base fits snugly and aligns perfectly with the tank opening. Checking the orientation before securing it is crucial, as a misalignment can lead to leaks.
After confirming the correct placement, apply sealant around the perimeter of the tank lid to create a watertight seal. This step is essential to prevent any leakage that could compromise the system’s integrity.
Step 2: Install the Riser Sections
Stack the riser sections on top once the base or adapter is securely attached, ensuring they connect seamlessly to reach your desired height. If you’re using plastic risers, apply PVC glue at the joints for a strong, lasting bond.
For concrete or heavier materials, utilize screws to secure each section firmly. It’s important to check the vertical alignment of the risers as you build to maintain proper drainage and function of the septic system.
Step 3: Seal the Joints
After installing the riser sections, it’s time to seal the joints. Use butyl tape or silicone sealant to thoroughly cover the seams between each riser section. Ensure that the sealant is applied evenly and smoothly to create a watertight barrier. This is a critical step as it prevents groundwater from seeping into the septic system and also helps prevent any odors from escaping, ensuring a healthy environment around your home.
Step 4: Secure the Riser to the Tank
To ensure stability, secure the riser to the septic tank by using screws or bolts through the riser base into the tank lid. Make sure that the fasteners are tight and secure to prevent any movement over time. This step is essential to avoid potential shifting, which can lead to misalignment or leaks.
Step 5: Install the Riser Lid
Finally, install the riser lid on top of the riser sections. Depending on the type of lid you are using, make sure that it is properly secured and locked if necessary. Opt for a heavy-duty lid designed to withstand weight and various environmental conditions, as this will protect your septic tank while ensuring continued access for maintenance. A well-fitting lid not only enhances safety but also prolongs the lifespan of your septic system.
Backfilling the Excavation
Step 1: Check for Proper Alignment
Before backfilling, ensure the riser is level and properly aligned with the ground surface. Use a level tool to verify that the riser sits straight and does not tilt. Make any necessary adjustments to the riser position to prevent shifting over time, which could lead to potential problems.
Step 2: Backfill Around the Riser
Carefully backfill the excavated area using clean gravel or soil, ensuring that you compact it down to avoid future settling. Start by filling around the edges of the riser, gradually adding material and packing it tightly.
It’s vital to create a slight slope away from the riser to direct water runoff and prevent any water from pooling around the riser, which could cause issues with your septic system. Aim for a smooth finish that seamlessly blends with the surrounding landscape.
Step 3: Final Inspection
After backfilling, perform a final inspection to ensure the riser is securely installed and stable. Check that the surrounding area is properly compacted and that the lid is tightly sealed to prevent any infiltration or odors. Confirming these details will help maintain the functionality of your septic system.
Maintenance and Tips
