Well I’m just checking to see if this is correct. It seems weird that there is a gray tank rinse but no black. Unless I’m missing something. It’s a 1996 Holiday Rambler Endeavor. The yellow highlights are the waste and gray drain valves the red is the gray rinse I think.

It’s probably mis-labeled. That is probably your black tank rinse. There’s probably a pex line that attches it to your black tank.

Easy way to find out is after dumping your black tank leave the valve open and hook your hose to your rinse inlet if it starts running out you know which tank it’s attached to. I have clear elbows in both ends of my sewer hose so I can see what’s going on.

Ok tried hooking hose to the waste water and got nothing in either tank there is a gray line running from it towards the black tank I believe but getting nothing in either tank.

'Waste water tank' IS the Black tank

No flow when connected:
Anti-siphon vacuum breaker check valve failure (typically located inside bathroom sink cabinet)
Nozzle installed in the sidewall of balck tank clogged......Most likely problem

Ok so do they have the drain valves mislabeled? As you see the valve on the left is the black tank valve(called sewage) this is a for sure. The one on right is the gray tank (labeled as waste tank, and the gray tank rinse as they call it is actually the black tank rinse?

Sewer Water Tank...black tank drain
Waste Water Tank....grey tank drain

Waste water tank....Black tank flush

No flow....most likely clogged flush nozzle in Black Tank

Ok thank you. The way it read didn’t make since to have a gray tank flush. Now Ijust have to locate the nozzle. I looked under bathroom sink seen nothing. Toilet is on passenger side of coach as well as the sink. Anyone have any ideas as to where I can access the nozzle or any ideas as how to unclog. Last day camping in FortCuster state park, Mi. then have to get ready for winter.

I have a wand but guess not much use as there is an elbow about a foot below the toilet. Am packing up to head home it’s a great 70 degrees today but by Saturday will be snowing and about 34 this weekend. I’m at a state park so will put whatever water I can into black tank and dump here at the park station, hopefully the splashing will free something up.

Ours was not working. Followed the lines and they seemed to go over the tank. Found the black tank flush nozzle on the opposite side of the hookup i.e. passenger side on our -04 HR. I had to remove a panel to access it.
I took the nozzle out & all the holes were plugged up. Soaked it for a few hrs and nothing. Had to use a wire to poke & open the holes.
Then used silicone sealant to seal the nozzle back in place.

Thank yo that helps I now know what to look for. There is a panel on opposite side with several screws maybe it’s behind it. Winterizing today so if I have time will check that panel.
