Abstract

A self-contained auxiliary sump pump battery-powered in response to a float switch, including an electrical battery charger for maintaining the battery in condition to operate the pump and having a battery condition indicator, a charger operating light, a manual test switch for actuating the sump pump, and a timer unit for automatically operating the unit through a test cycle.

Claims

1. A battery-powered auxiliary sump pump apparatus remotely positioned with respect to a sump and an electrically operated main sump pump, wherein the improvement comprises a. a protective housing for the apparatus remotely positioned with respect to the main pump, b. a secondary pump within said housing and having external connections to a secondary sump siphon tube and a secondary sump discharge hose, c. a battery-powered electric circuit for said secondary pump, d. battery charging components for said battery including an electric circuit having a manually operable switch for energizing said battery charging components, e. a float switch in said battery circuit for energizing the apparatus in response to excess fluid levels in the sump, f. a test switch in parallel with said float switch in said battery circuit for energizing said secondary pump for testing its operating condition, and g. a control means providing a relay in circuit with said electrical circuit and a set of relay switches connected in said battery circuit with said relay being deenergized upon failure of said electrical circuit to actuate certain of said relay switches, so as to cooperate with said float switch to connect said secondary sump pump to said battery.
