The non-Standard Sump Pit Good Morning
Depending on the size of the pit we will put a piece of Lexan on the pit seal it down drill our holes for the piping and wires and install a dranjer valve. Sometimes will we will use the solid sump pump cover doing the same thing and then we add a site glass to the lid, or use the new clear some covers. Put a label on in it stating that it is part of the radon reduction system.
We have had very few problems doing them this way.
