Hi, I have posted this before but recieved different answers so I will be more specific. When I go to flush out my black tanks it leaks from above, which is right by the base of the shower or so it seems.some of you have said to look for a valve behind the top front drawer off the bedroom but it is not there, my coach is a Winnebago Adventurer 38G would it be in a different place on this model? I have also looked behind the bathroom drawers and still see no valves. Any help is appreciated.

Thanks,
Dean

Totally understand your frustration!
Winnebago told my neighbor his was accesible under the sink un the bathroom, NOT!!
If we had approached it from that angle, we would have to dismantle the sink base, wall, and part of a closet!
It will be accessible, weather it is under the sink, pull the bathroom vanity drawers, might be there. It may be in the access port, that would be avaliable for you to service your shower valve. that would be a small panel, held on by a couple screws, it could be behind a door, inside an adjacent closet...just look, carefully, you will find it.
Your problem sounds exactly like my neighbors, perservere, you wil be the winner!
The vacuum breaker has to be higher than other plumbing loops, so that when you shut off the water going into the clean out sprayer, the water drains back to just below the valve, where it "sucks" down a spring loaded valve, letting in atmospheric air pressure, stopping any further flow...pretty simple device, until it gets something stuck in it! Keep looking..keep us informed...

Dean, are you sure that the pipe that goes from the panel where you hook up your hose to the tank is not broken or loose where it goes into the tank. if you look behind or under the panel can you see where it goes into the tank? I do not understand how it can be coming from above. the pipe should go straight into the tank. is it spraying up and comming back down? do you have a sewer smell in that compartment between dumps? be sure to let us know what you find.

Mikf, It's possible the line is broken but it goes up behind the dump valves and dissapears into the body never to be seen, when I turn on the water to flush water comes out almost immediatly, so right now I'm just stumped, Thank you for your reply,
Dean

Thanks Free to Roam, I'll keep looking, Thinking I'll remove the mirror that backs to the shower tomorrow and see if there is an access panel behind it, I've looked everywhere else. I'll let you know......
