Grey Water & Drains

Grey water and drain pumping covers fixtures that produce wastewater without a full toilet load—think showers, laundry trays, bar sinks, and commercial prep sinks—when you must lift or push that flow to the building drain. Residential and commercial-tagged pumps in this collection help you separate light grey water duty from blackwater macerators for clearer code conversations with your inspector. Always confirm allowable discharge paths and filtration expectations in your jurisdiction. For kitchen-sink or utility-only pumps, also see drain pumps; for toilet stacks, use macerating or lift-station solutions.
