MACERATOR PUMP NOT WORKING ... AGAIN!!!!

Traditionally many RVs had black and gray gravity dump through one 3" hose. Before that black and grey usually were a combined tank. The idea was to pull the black valve first, close when finished and then flush with the grey water to reduce cleanup. The water hose at most dump stations could then be used to do a final cleaning of the 3" corrugated dump hose if needed. I don't have a macerator but assumed one would prudently follow the same procedure and always dump black first. We don't have problems with the black since we use it quite a bit for number 1 and number 2 only in emergencies. Being a little liberal with the flushing also helps add water to the black tank. The idea I think is to not let your black tank get too dry and use the right kind of toilet paper that disintegrates.

Our next B will have a macerator but connected to a 3" diameter outlet that you can uncouple and add a 3" corrugated hose to to gravity dump as well. Best of both worlds so to speak.
