| The Jabsco 18590 series DC macerator waste pump is the idealisti solution for boaters who need to empty marine keeping tanks when not in a discharge-restricted area. Self-priming to 5 feet, the pump will empty a typical 30-gallon (115-liter) keeping tank in less than three minutes. The pump’s obligation cycle, meanwhile, is 15 uninterrupted minutes, which means you may empty a 180-gallon (680-liter) pump in a single operation. The macerator pump is likewise a good choice when emptying fish box and livewell receptacles. Specific features include a Jabsco Nitrile compound impeller, a stainless-steel cutter that reduces the particle size to 1/8 inch maximum, and a lip type seal.
Specifications:
- Pump: Self-priming flexible impeller with stainless-steel wearplate
- Inlet port: 1-1/2-inch (38mm) hose barb and 1-1/2-inch N.P.T. (male)
- Outlet port: 1-inch hose barb
- Motor: Permanent magnet type, entirely enclosed, with stainless-steel shaft; includes run-dry shelter device that shuts off pump
- Voltage: 12 EMC
- Amp draw: 16 amps
- Fuse rating: 20 amps
- Weight: 5 pounds

 Great macerator pump!
By gary P.
I installed one of these on my RV sewer outlet a year ago and it has been wonderful. I just flip a switch and it empties the holding tanks in a few minutes through a 3/4″ garden hose. Required some creative plumbing work to hook up, but nothing too difficult for the mechanically inclined. Recommended.

 Design flaw
By BC
The 18590 pump is held together with 4 BRASS studs. These studs are exposed to the effluent the pump discharges and they dissolve in about three to six months, allowing the pump to come apart and the sewage to leak into your boat. Jabsco has not responded to my inquiries about this problem. Jabsco needs to change that design. Don’t buy this pump unless you fabricate bronze studs to replace the brass ones.

 Jabsco 18590-2092 Marine Run-Dry Heavy Duty Macerator Waste Pump
By Duane
I purchased the Macerator waste pump and plumbed it to use on my Motor Home. It took a lot of time to plumb it to work on my RV but once it was plumbed up it works very well. It calls for a 1″ ID outlet hose but I plumbed it using a 5/8″ garden hose on the outlet side of pump and it seem to work ok. The only thing is the Thermo Overload will stop pump if it run from 3-5 minutes. I think it is because of the 5/8″ outlet hose which is 120 feet long causing the pump to work harder.
