Manometer of Depressurization Radon Mitigation System in Pilger, NE

The manometer reads the pull of the exhaust fan that is drawing the radon gas up and out of the home. We look for a 'J' to know that the fan is drawing up air adequately. If the manometer is sitting at a "U" then there is no pull, or suction, removing the radon gas from the home and it's time to inspect the fan and look for any other obstructions. After installing this radon mitigation system in Pilger, our technicians knew they were on the right track when they saw the fan had adequate pull.
