I have a fairly new septic system that I want to add a riser to. Currently, there is already a riser on the tank, but it sits below grade and I have to dig for it. I had a falling out with the installer so he probably did that on purpose.

Is there a way to extend the existing 24" black corrugated pipe up to grade and then use a riser cap? I need to come up about 15". All the kits I'm finding online are designed for concrete tanks (mine's plastic).

Any and all help appreciated.

The plastic ones are usually proprietary. Do you know what manufacturer it is? Are the current risers threaded into the top of the tanks?

I contacted Septic Solutions and they hooked me up with an adapter and riser kit.

Thanks for the help.
