Sewer Flush Mystery
My ’92 CC has a garden hose connection on the panel covering the tanks that is supposed to connect to the sprayer in the black tank. Nothing was connected on the back side.
Upon inspection I found two sections of PB pipe. Both run through a hole in the bay ceiling right next to the toilet. It looks like they would originate in the knee-wall behind the toilet.
One pipe runs all the way over to the passenger side running along the top of the tanks. Someone told me the sprayer fitting is on that side.
The second is a short stub which is capped off. It has a tag that says sewer flush.
It would make perfect sense for the long pipe connected to the tank to connect to the garden hose fitting.
I am baffled why the stub and the long line run up into the coach.
Ideas? -

Some systems have a vacuum breaker on the stub that goes above the tank to prevent any back siphoning. Don’t remove it 🙂

Liam,
That stub is/ was an anti-siphon that Country Coach uses on their sewer flush system. It’s there for access for repair/replacement and places it above the tank. The newer Country Coach products have two, one for the black tank, one for the gray. Your local home center should have a replacement if necessary.

Cool, so hidden upstairs in the coach is much the same part as used with a dishwasher drain hose? So I should simply be able to connect a section of pipe between the garden hose connector and the stub and keep my fingers crossed the flush sprayer still works? I was told they get clogged and then folks disconnect them.

I would get the proper vacuum breaker and reinstall it where the cap is.(are you sure that cap is not the vacuum breaker, they do look like it in that application??) You should locate the tank spray and remove it and clean it, as they do clog. I am sure CC put some sort of access panel where that spray is. The nozzle is held in place by stainless screws and a bead of clear silicone. Clean the nozzle or increase the holes by one drill index size, put a bead of clear silicone around the nozzle flange, reinstall the screws.(just snug)
