20 inch diameter septic tank riser kit with dimensions

20-inch Riser Kits

Each 20-inch kit comes with a domed lid, sealant, and screws for installation. The deeper your tank is, the more riser rings you'll need to reach the surface. We have various pre-measured heights available in this 20-inch diameter size, although additional riser rings can be purchased separately if needed.
