DOMETIC 317301200 Overboard Discharge Pump

New somewhat larger 12 v motor is MUCH quieter than original. This unit is for overboard discharge, i.e. from black water holding tank to overboard. It is NOT the pump used to empty toilet bowl and pump to the black water tank.

Bought for a spare.

I really like this pump, it is easy to install, you don't have to worry about burning it out as it will run dry without a problem. Much better than the macerating pumps that are available. It costs a little more but well worth it when you don't have to replace every couple of years. I highly recommend it.
