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.

Cap + Elbow
