Basement & Radon Solutions, BRS Pros, finished the piping and installed a HP 220 radon fan to Steve’s partially finished passive radon system. The reason for this is because a passive system has no suction to get rid of the radon gas. The new radon fan will create the negative pressure required to remove the radon gas before it enters the home. We also conducted a 48 hour radon test after the radon fan was installed. The radon test came back at 3.4pCi/L which is a great improvement! It was such a pleasure helping Steve make his home happy, healthy, and safe!
