macerator stopped working

Hello all,

Just returned from short trip in our 07/08 RT190P and experienced macerator problems.

The volume or force of the flow seemed less, and the macerator motor seemed less noisy as well. Clearly it took longer to empty but was still working.

Tried to empty the holding tanks after getting home but this time the macerator was not pumping at all, despite hearing its motor trying to work.

I have tried churning the contents of the tank with my black tank water spray cleaning wand, as well as back washing through the discharge hose. Unfortunately neither has helped.

Now I have a full black tank (mostly water, no solids) and no way to empty it! Winterizing will be a problem.

Does anyone have any ideas on the problem and/or solutions?

Many thanks,

Arvie1
  • Thank you jdc1, Jim&Carolyn, MitchF150 and bdpreece,

    I appreciate your comments and have booked the earliest appointment for replacement on Oct 12th. We only turned 50,000 miles on this last trip and try to keep our RT in the best condition we can...even no tissue in the black tank! This will be my second replacement macerator! A little disappointing for so little use, but maybe that is part of the problem.


    Hopefully I can figure out some way to empty the tank before taking it to the RV Centre so they don't have to endure that unpleasantry!

    Thanks again for your input.
  • When mine went it was the impeller which has rubber blades to pump the sewage. I ordered a new impeller and rebuilt mine. Kind of an icky job but a lot cheaper than a new unit.
  • yeah, I'd just buy a new one and move on with life.. :)

    Good luck! Mitch

    You'll need someplace out in the boonies and a large piece of plastic sheeting, buckets, sponges, and hell of a lot of water...cause this is fix'n to get real messy. You may have start taking you waste lines apart right where the pump is located.....
