Review on 🔧 Jabsco 18598-1000, Macerator Pump Service Kit for 18590 and 18690 by Javarie Malick

Comes with a sachet of lubricant. In our case, the housing was not needed since only the impeller was old and deformed. Once the pump has been removed and flushed, installing a new impeller etc. is easy. The impeller is accessed behind the chopper blade and the protective grille, which must be removed from the motor shaft. The nut holding the chopper blade in place is easily removed by holding the blade with pliers while loosening the nut.
