ABSTRACT:
The present invention provides a sump pump control system. The system includes a mounting fixture fabricated from a corrosion resistant material, and an electrical control comprising solid state electrical components supported by the mounting fixture. The sump pump control system also includes a diving bell cover. The diving bell cover has an open bottom, and is dimensioned to cover the electrical components. The diving bell cover is releasably secured to a support surface of the mounting fixture. The electrical control controls the operation of a sump pump. Should water rise to a level of the electrical components due to failure of the sump pump or due to quickly rising water, the diving bell cover will prevent water from contacting the electrical components. A method of removing water from a subterranean vault is also provided herein.
