Septic Tank Risers for Carrollton Homes
Many septic tanks in Carrollton sit a foot or more underground, which means digging every time the tank needs pumping or inspection. A riser brings the access opening up to ground level so the tank can be reached in minutes.
A local septic company that serves Carrollton and White Hall, Greenfield, Jerseyville can install risers and secure lids, often during a regular pumping visit.
What a septic riser is
A riser is a short pipe or collar, usually plastic or concrete, that attaches to the tank opening and extends it to ground level. A lid on top, typically secured with screws or a lock, keeps it closed. Most tanks have at least two openings, and many benefit from a riser on each, plus one on the effluent filter.
Benefits of adding risers
Risers cut the time and cost of every pumping and inspection, since no digging is needed. They make it easy to check the effluent filter, spot problems early and show inspectors the tank during a home sale. They also protect your lawn from repeated digging.
Installing risers on an existing tank
Nearly any concrete or plastic tank can accept risers. The installer matches the riser to the opening size and material, seals it to keep water out, and secures the lid. Lids should always be fastened so children and pets cannot open them.
Keeping riser lids safe
An open septic tank is dangerous because of gases and deep liquid. Riser lids should be screwed down or locked, rated for foot traffic, and replaced right away if they crack. Never leave a lid off unattended, and keep children and pets away while the tank is open.
What a riser job costs depends on
The price depends on how many openings get risers, how deep the tank is buried, whether plastic or concrete is used, and whether the job is done during a pumping visit. Deeper tanks need taller risers and more digging, which adds labor time.
Questions to ask about risers
Ask how many openings your tank has, which should get risers, what material they use, and whether lids are secured with screws or locks. Ask if they can install during your next pumping.
Plastic or concrete risers
Plastic risers are lightweight, easy to trim to height and do not corrode, so they suit most existing tanks. Concrete risers are heavy and durable but harder to install and can let in water if joints are not sealed well. Your septic company can recommend the right option for your tank.
After the risers go in
Make a note of where the lids are for future owners and service crews. Mowing around them is easy if they sit flush, and they make it simple to check the effluent filter or water level. Report any loose or damaged lid to your septic company.
Good times to add risers
The best time to add risers is during a scheduled pumping, when the lids are already dug up. They are also worth adding after buying a home if no one knows where the lids are, or if your service company charges extra to dig.
Choosing riser lids for a Carrollton yard
Riser lids for Carrollton homes come in green or brown plastic and in concrete. Plastic is lighter and easier to open, while concrete is heavier and harder to move. Either way, the lid should lock or screw down. Ask the installer to seal the joint so groundwater cannot leak into the tank.
