Black Tank Flush
I have an 06 3295RK. Went to use the black tank flush last time out (in July) and it didn't work. Last time I used it was Nov 07 and everything was fine. Now, I hook up and turn on the water and nothing. I disconnect the water, and water drains out the fill. Help!!!

Welcome to the Forum!
Couple of things might be wrong -
The internal tank nozzle is plugged with stuff (unlikely)
The vacuum break valve is stuck (likely). The flush hose runs somewhere up the wall of your rig to to an automatic valve, then back down into the tank. The valve opens when you shut off the water supply and allows air back into the line so the water will drain out. This prevents back siphon of the tank contents into the potable water as well as your water inlet. These fail quite a bit. Ours is located behind the shower in the wall, accessed by a removabe plastic panel in the pantry. I'm not sure where it is on your model.

My valve is also behind the shower and access panel in the pantry. It failed my first trip out. Replaced under warranty. I think it still works??

Not to unlikely Brad. Just last fall before the Fall Rally my flush also stopped working. When I got to Goshen they found the nozzle was in fact clogged with $H*&. Both Techs were dumfounded as neither ever saw this happen before. I had completely flushed the black tank just days before. Stayed 2 nights without dumping and when I did dump the flush wouldn't work. They even showed me the old nozzle, not something I wanted to take a photo of.

Our black tank flush valve is leaking, but we do not have an access panel in our cabinet. We have an 07 3400rl. I think they forgot to put one in. Can someone please let us know where theirs is located so we can make one. thanks

Ours is in the pantry, about 6' up off the floor (back of the shower). Make sure the sliding door is closed. If its open, it looks like the hole doesn't go anywhere.
