Sump Model Fits Your Sump Cover

The FS2 allows water to flow into the sump but prevents soil gases from entering the home.

How Your Dranjer F Series Works
F Series have a sealing ring that lifts when water enters the valve, allowing for the water to flow through the unit.
In a no flow environment, the sealing ring prevents radon gas from passing through or past the unit. This effectively reduces radon levels in the dwelling.
Dranjer products are engineered and laboratory and field tested. Dranjer products are DIY friendly. Dranjers are often installed association with an ASD system but may be the only action you need to reduce your radon levels.
