Jabsco 18598-2000 Macerator Service Kit
The Jabsco 18598-2000 is the genuine service kit for Jabsco 18590 and 18690 series macerator pumps. It includes two gaskets, a nitrile impeller, the small wearplate, a pump body with discharge port and a lip seal. It no longer includes the two short studs or fiber washers, which are no longer used.
Macerator pumps grind waste into a fine slurry and pump it from a holding tank to a deck fitting or overboard where permitted. Keep the chopper, wearplates and impeller in good condition, since worn parts reduce flow and let solids jam the pump. Never run a flexible impeller macerator dry, and flush it with fresh water after emptying the tank.

Frequently Asked Questions
Q: How often should it be serviced?
Inspect the impeller, wearplates and chopper at least once a season, and more often with heavy use.
Q: Why does my macerator hum but not pump?
Usually the impeller is damaged from running dry or the chopper is jammed with debris. Isolate power before checking.
Q: Can the macerator run dry?
Flexible impeller macerators must not run dry except run-dry models, which tolerate it for limited periods.
Q: What should not go through a macerator?
Wipes, rags, sanitary products and hard objects. They jam the chopper and wear parts quickly.
