I think it is the cheap way for the radon specialist to install.
When I see a floor with excessive cracking & water intrusion. I want to see the pump & the foundation drainage. How can the pump be accesable if it is in a sealed radon mitigation system. Seems like a cheaper way for the radon system to be installed.
I see to many crocks filled with water & a defective pump that is why the floor gets cracked and water intrusion from hydrostatic pressure.
I sure dont want to be the guy that gets the blame when the basement floods or gets a puddle.
