RadonAway RP260 6" Radon Mitigation Fan | High-Performance Radon Gas Reduction System for Basements & Crawl Spaces | Model 23032-1

This fan is great... very quiet (if installed properly) and very efficient. If you are building your own mitigation system, don't forget to purchase the 6" to 4" couplers... 6" X 4" Flexible PVC Coupling for 6" Fan Mounting - White, 2-PackOther items you may consider would be a manometer, regular couplers (if connecting above sump pit cover) and a vent cap. I bought the following:RadonAway® Easy Read U-Tube ManometerFernco Inc. P1056-44 4-Inch Stock CouplingRadonAway Fan Pipe Cap with Screen for 4" PVCSafety Siren Pro Series3 Radon Gas Detector - HS71512 by Family Safety Products, Inc.My basement had an average radon level of just over 4.0 pCi / liter so I wanted to install a mitigation system. I designed and installed one myself using 4" PVC pipe venting from the sump pump pit cover in the basement, through the wall outside where it connects with the RadonAway fan and remaining PVC pipe up the side of the house venting above the roof line. Radon levels dropped from around 4 to 0.3 on my electronic detector. So I have concluded that my radon mitigation system is a success! Everything continues to run smooth and quiet. I'll post updates if anything changes.
