Will my sump pump still work with a sealed pit?

Yes. The airtight sump pit cover is designed with proper penetrations for the sump pump discharge pipe, power cord, and radon vent pipe. Your sump pump continues to function normally — it just operates beneath a sealed cover instead of an open pit.

Is sump pit depressurization as effective as sub-slab?

When the sump pit connects to the home's sub-slab drainage system (drain tiles), sump pit depressurization can be equally effective as traditional sub-slab systems. The drain tiles act as a collection network, and the sump pit serves as the central suction point.

What if I don't have a sump pit?

If your home doesn't have a sump pit, a traditional sub-slab depressurization system is recommended instead. A certified technician will core a hole through your basement slab and create a suction point specifically for radon mitigation.

About Sump Pit Systems

If your home has an existing sump pump pit, it can often serve as an effective radon suction point. Sump Pit Depressurization involves sealing the sump pit with an airtight cover, then connecting it to a vent pipe and radon fan. The pit's connection to the sub-slab aggregate makes it an ideal collection point for radon gas, often eliminating the need to core additional holes in your basement floor.
