How Your Dranjer J Series Works
J Series have a ball valve that floats, allowing for high flows through the unit.
When the flow stops the valve closes and radon gas can no longer flow up through the floor drain or sump cover. Effectively reducing 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.
The JS15 Drain Sump Valve is designed to fit into and become part of your sump cover.
