![]() We have noticed that many home owners do not service their sump pump as the manufacturer recommends. Proper maintenance of the sump will save you money. Contractors using latex caulk (cheapest caulk) are not providing the best longevity for reproducible radon reduction. It has the best elasticity and remains flexible longer than polyurethane caulk sealant. Using silicone caulk sealant is the best. What kind of caulk do you use to seal cracks and the sump pit cover? Note: make sure any electrical cords do not interfere with the operation of the sump pump and that float switches are able to move freely. Make sure all penetrations through the sump cover are re-sealed. Ĭan I re-seal my ground water sump pit myself? The effectiveness of the radon system will be compromised if the sump pit cover is not properly re-sealed. Is re-sealing my ground water sump pit really necessary after servicing or replacement? ![]() Your house is always forcing air into itself through the amount of pressure it exerts on the ground, barometric pressure, temperature differences and convective airflow. If it were only that easy! Radon will travel right through a concrete floor. By then, a typical house would have exchanged its air about 4 times.Ĭan’t I just seal my sump pump and floor cracks to keep radon out? Second, the home is required to be closed-up except for normal entry and exit for 12 hours prior to the start of the test. This is due to the operation of the HVAC system and general draftiness of most homes. First, a typical closed-up house exchanges all of its air about every 3 hours. Actually there are a few reasons why this isn’t true. Is that the reason my radon levels are elevated? My house was closed up for a long period of time prior to the start of the radon test. The only way to know your home’s radon levels is to perform a radon test. Click here to see the prevalence of radon in your area. Are there areas (towns or counties) in Illinois where radon is more prevalent?
