Jabsco 24V Filterless Single Diaphragm Waste Pump

The Jabsco 24V Filterless Single Diaphragm Waste Pump (part 50890-1100) moves gray water and toilet waste through 1-1/2-inch (38 mm) bore hose. It is a common choice for pumping out a holding tank or transferring gray water on boats with 24-volt systems. The listed flow rate is up to 19 liters per minute.

Waste pumps need large valves and a clear path for solids, and this one has no strainer to catch and clog. It self-primes from a dry start, so it can be mounted above the holding tank where it is easier to reach. The ports can be turned to several positions, which makes hose routing simpler in a crowded space.

Before running it, make sure the discharge is legal for where you are, since many areas require holding tank pump-out instead of overboard discharge. Flush it with fresh water after heavy use and check the diaphragm and valves once a year. Keep feminine products, wipes, and rags out of the system, since they can still wrap around the valves.
