While the radon levels have dropped markedly, there was a leak in the wall by the system during the extremely heavy rain in early April. This is worrisome. I did not call at the time as I wanted to see if it happened again.

You are located close to my home. Also you were responsive to the phone call that I made. I am happy with the system but I am worried that the wall will leak again with an extremely heavy rain.
