Effluent Pumps - ¾" Solids Handling

Effluent pumps rated for ¾ inch solids handling, in ⅓ hp through 2 hp ratings.

Effluent sits between clean groundwater and raw sewage. It is the liquid leaving a septic tank after settling, carrying particles larger than a sump pump can pass but nothing like the solids a sewage pump is built for. Three quarter inch solids handling is the specification that defines the category.

Using a sump pump on effluent duty is the common and expensive mistake, because the tighter clearances clog. Going the other way and fitting a sewage pump wastes money and can move the liquid too fast for a filtration bed. Our explainer on what effluent pumps handle covers the distinction, the solids ratings and how to size one for a septic system.
