ABSTRACT:
A novel sump pump strainer assembly consisting of a basket having elongated circumferentially spaced openings disposed in a sump pit and having a sump pump located thereon. The basket is provided with a screen around its lower portion to prevent the introduction of debris into the basket that could clog the inlet of the pump. A shield on the basket is located opposite any inlet into the sump pit above the screen to prevent debris from entering the basket above the screened portion. In another embodiment, the pump is disposed on a specially designed platform that assists in directing debris away from the inlet of the pump. This platform can include a strainer attached thereto if desired.
