Sounds like you made the Misses happy ... and that's the goal... but great job at bringing down the Radon level so low!
I am looking for a "sealed sump pump well" (like you have)that allows water in so if I have a water leak, washing machine ...etc, my sealed crawl doesn't turn into a fish bowl : ) What did you use? www.SealedSolution.com Thanks!!

My sump pump well was just a 16" corrugated plastic pipe sunk in the ground ~ 3 ft. I sealed the top of it with plexiglass so the vacuum the fan created could only pull air from the dirt at the base, the below grade perimeter 4" drain which dumped into it and the the hole I dug under the slab. The sump pump itself has a back flow valve so air wasn't sucked out that direction. There are no other external penetrations to the sump pump well. My basement drain emptied into a separate lift station which I installed to support a basement bathroom.
