How to Seal a Sump Pump Basin
A sump pump basin is just one of several names referring to the container holding a sump pump. It is also called a sump pit, pump well or pump liner. The high-grade plastic basin sits about two feet underground and is a reservoir for ground or flood water. A float, moved by rising water seeping through the basin's porous wall, triggers the sump pump. Should a basin become a source of lethal radon gas emission, it will require sealing and a cover put in place. Basins also need sealing to prevent debris, insects, small pets and children falling into it.
