Abstract: Many existing sump covers have large access slots to accommodate the location of the sump pump discharge pipe. The exposed slot can allow undesirable soil gases to enter a home. The SUMPSEALER is a retrofit device that: 1) Uses a one piece reversible attachment to cover both sides of the slot simultaneously. 2) A mating part is used to cover the area around one or more electrical cords and position the cord(s) next to the pipe. 3) Both parts are clear and serve as a “viewport” enabling visual inspection without removal of sump cover. 4) By using caulk or sealant and utilizing the SUMPSEALER device, the existing sump cover can seal out undesirable soil gases.

Abstract: Radon Removal System comprised of an inline suction fan with “y” type fitting below it. The “y” type fitting is attached to a mounting flange that is positioned over a 4 inch hole in the sump cover or other depressurization port allowing the suction fan to draw air containing radon gas or other contaminants from drain tile(s) having fluid communication with the sump basin. The side inlet of “y” fitting draws exterior air from a flexible or solid PVC pipe located 3 or more feet from the discharge point. The suction fan draws exterior air into the side inlet of “y” fitting and dilutes the radon gas drawn into the lower opening of “y” fitting. The suction fan simultaneously dilutes the contaminated air with clean exterior air before being pumped out of outlet port. The expelled air is discharged into the outside atmosphere where it is further diluted to safe levels posing no health risk. With this system, it is no longer necessary to route the discharge pipe to the highest eve of the roof.
