A grinder pump is placed in a tank (or well) that is buried in a convenient outdoor location on a homeownerâs property (grinder pump units also can be purchased for inside installation). The tank provides wastewater holding storage capacity. When water is used in the house, wastewater flows into the tank. When the wastewater in the tank reaches a pre-set level, the grinder pump automatically turns on, grinds the waste, and pumps it out of the tank via the homeownerâs on-site sewer service line and into the public sewer system.
âI need a grinder pump.â is a call we often get from plumbers when in most cases what they really need is a sewage pump. Some people think that all sewage pumps grind up the waste when in fact they pump the 2â³ solids by velocity with either a âvortexâ or âdeep vaneâ impeller. The âdeep vaneâ impeller will break up the sewage, but by no means will it be ground up.
