RADON MITIGATION-WHAT DO I DO IF MY TEST COMES BACK HIGH? radon system So, you had a radon test and it came back high, now what do you do? Radon mitigation is a relatively simple system that keeps the radon from entering the house in the first place. Radon comes up from the ground as uranium decays and typically enters the house from the basement and more specifically, through the drain tile system, into the sump crock, and then into the basement. The goal of the mitigation system is to interrupt that process by venting the radon outside and above the roofline before it has a chance to come into the basement. This is done by sealing the sump crock and using a fan to pull the radon out. Notice the round object in the picture near the bottom about the size of a basketball. Per EPA guidelines, that fan can’t be in livable space. It is typically on the exterior, garage, or attic. This is because if the couplings are not sealed properly from the fan to the piping, you are now actively pulling radon into the living environment and making things much worse. Proper operation of the fan can be observed on the piping via the radon manometer. This is a U shaped vial of liquid, that indicates suction and fan operation. It does not indicate the level of radon. The only way to know the level of radon in the home is to test for it. Visit our website for more information or to schedule a test.
