Hello all,
We are under contract to buy a home with an ICF basement and a radon mitigation system (sub-slab pipe and fan). An inspection found that the radon was not being mitigated by the fan. More inspection found that the fan had stopped drawing enough air volume. Even more searching found that the PVC blackwater pipe for the basement laundry had broken under the slab causing the water levels under the slab to rise and block the radon vent pipe. The sellers are in the process of having this fixed.
Our concern is, what would cause this PVC pipe to break under the floor? The house was built in 2003. The pipe was not broken in 2012 when the radon vent pipe was installed. I know very little about ICF basements or foundations in general but if this pipe is broken, should we be worried about the other pipes under the slab?
