Unlike centrifugal pumps, the Gulper 220’s large diaphragm design handles shower water, soap residue, and small debris without a strainer or filter — one less maintenance item to worry about and one less failure point in the system.\u003c\/p\u003e\u003cp\u003eThe pump runs dry without damage, so it won’t burn out if the sump empties before the pump shuts off. Self-priming to 10 feet means it can be mounted above the wet area, keeping the motor out of standing water.
