Jabsco 18594-1001 Macerator Housing, 3 in
The Jabsco 18594-1001 is the genuine macerator housing for Jabsco 18690-0000 and 18690-0010 AC macerator pumps. The housing carries the inlet and encloses the chopper plate that grinds the waste before it reaches the impeller. Replace it when it is cracked, leaking or worn after years of grinding duty.
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: 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.
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.
