Hi there group! So I recently came across a radon mitigation system that had 5 entry points of PVC in the foundation leading to one to mitigate to the exterior.
I have attached some pics. So to the radon experts………Why a system with 5 entry points? This because the radon levels were very high? I don’t know what the levels are now and I am encouraging the peeps to retest the levels. Also, why do you think it is leaking? Condensation? I don’t love the caulking that they used to seal it. There is obviously efflorences present.
Any feedback would be a great help. Thanks!
