Radon Condensation Bypass

radon fan guard

Outside systems produce considerably more condensation than inside pipe routes. We strongly recommend routing some of this moisture around the fan to lengthen the life of the fan and so does the manufacturer.

The system on the right is preferred especially if you live where it's cold enough for ice to form regularly. The trap where the black hose originates will catch falling ice.


System comes with nylon nipples tapped into a PVC 90º elbow and cap. 3' of vinyl hose and insulation included. Match to the size pipe of your system.

3" Condensation bypass......$19.95
4" Condensation bypass .....$22.95

Nipples are tapped into a special PVC collar and 90º elbow. 3' of vinyl hose and insulation included. Match to the size pipe of your system.
