Jabsco 18590-2092 Run-Dry Macerator Pump, 12V
The Jabsco 18590-2092 is the Jabsco 12 volt run-dry macerator pump, a sealed macerator that tolerates running dry for limited periods at the end of a tank pump out. It has a stainless steel chopper plate, stainless steel wearplates, a nitrile impeller and a 12 VDC motor, and it shares the 18594-1000 housing and 18593-1000 body with the macerator family.
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: 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.
Q: How often should it be serviced?
Inspect the impeller, wearplates and chopper at least once a season, and more often with heavy use.
