ABSTRACT:
A vacuum system is utilized for preventing radon gas from entering the basement of a home. The gas is drawn from the interior of the basement walls, the exterior of the basement walls and from underneath the floor into a drain tile under the floor where the gas is then evacuated to vent pipes extending to the top of the home where the gas is vented to the atmosphere. A water trap is provided in a pipe extending from a first drain passageway between the basement wall and the exterior edge of the basement floor to the drain tile under the floor preventing radon gases from moving upwardly into the basement. The first drain passageway and floor and wall are sealed against migration of gases upwardly from under the floor.
