Description

The Everflo EFSW4000 is the “Soft Wash” version of the standard 4.0 GPM pump. Because soft wash systems use high concentrations of bleach (sodium hypochlorite), the internal components are designed to be more chemically resistant than a standard water pump.

A complete repair kit for this pump typically addresses the two most common failure points: the Valves and the Diaphragm.
