ABSTRACT:
A sump crock cover for airtight istallation on the surface of a floor directly over a sump pump opening is disclosed. The cover includes a sump lid base member of generally circular shape having two spaced apart annular sealing rings which assit in preventing the escape of hazardous gases such as radon enriched soil gas. The cover has an integral radially extending ribbed section with a central aperture for the purpose of receiving a flexible grommet which provides a seal around sump discharge piping and electrical wiring. Effective O-ring sealing is obtained by positioning the O-rings radially inwardly and outwardly of the bolts which mount the cover to the floor and by providing for installation of the O-rings in grooves in the sump lid so that the O-rings extend beyond the plane of the sump lid.
