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!
Sub-slab conditions may not be appropriate to allow for easy airflow and for a single access point, thus the need for multiple points. Some homes require multiple systems to achieve maximum evacuation. This may be the ‘redneck’ method of that need.
Thanks Jeffrey and Larry, yeah I have seen 2 mitigation systems on either side of the basement to tackle difficult sub-slab conditions but nothing like this, that’s why I wanted to reach out.
