Black water spray flush ???

[bobioknight]

Seriously, are you guys telling me that you overflowed your black water tank into your coach. Holy Sh&% (literally) that must have been horrible. I will definitely learn from your mistakes and watch over this process very closely. Oh my gosh.

Ours is clear up under the bath sink, have had it replaced once under warranty and then had to take it apart a few years ago to free it up. Haven't used the sprayer since, just don't need it if you fill the black tank ¾ full before dumping.

Not quite. At least in my case, the toilet seal prevented anything from getting into the coach but I learned it will sure back up through the vent pipe and pour on to the roof.

Fortunately, I had already dumped, filled, dumped again and was filling for another strong flush so the water wasn't as bad as it might have been.

Locate the spray head on your diagram,remove it and drill the holes out to 1/8th. it is blocked with TP.

The piping from the black water flush inlet to the black tank should have both a check valve and an antisyphon preventer in the line - and as a further safety measure the backflow preventer might be mounted higher than the top of the tank. May have to get to it from above floor level through a cupboard.
