Restore the flushing performance of your MasterFlush toilet with the Dometic / SeaLand Pump & Motor Assembly (Part #385311993). This 12-volt macerator pump assembly is designed for select Dometic MasterFlush 7000-series toilets, providing the power needed to grind waste and pump it efficiently to the holding tank.

The pump uses Dometic’s macerating technology, which grinds waste and toilet paper before moving it through the discharge plumbing. This allows MasterFlush toilets to operate with smaller diameter sanitation hoses and flexible plumbing layouts, making them ideal for marine vessels and specialty RV installations.
