I know one thing for sure, before I use the black tank flusher in my unit, I will find out where that valve is located first. Don't use our black tank much for the dirty deed. Just go to the campground facilities to eliminate a lot of problems I read about on here!

When you do find it, just delete it and your worries are over. We had a similar incident as arkhillbilly in the first RV. That one was in a wall behind the TV. We've ditched them ever since. On most, where the pex goes up to the valve, then back down again, we just rid of those pieces and make a straight shot.

I bought a back flow valve at home depot for about three bucks, and leave it attached to the separate hose I use for that type thing. One inch of water in my furnace was enough. I blew it dry with a hair dryer, and it worked the next day. I dreamed of dollars out the window that nite for sure.

Why anyone would put a backflow preventer inside the camper is beyond me... it should either be outside the camper wall, or emclosed and able to drain outside. Any other arrangement is just a ticking time bomb...

Not sure what companies are thinking. You can go to a number of forums with other brands, and the problem with that 571 valve goes back a few year. I read the set up instructions from the mfg. to a Jayco service rep, and got a big yawn! I hear most of the newer units have it by the toilet. That way when it fails to work, it can flood the bath floor and get into the underbelly!! Its a CYA , for somewhere in the owners book I read that one was not to flood the floor with water.

Is this an issue in Grethawks or just TTs?

Anyone have experience in GH flooding or removing it?

Its a industry problem. It is usually a b and b ind number 571 anti back flow valve, usually located on the black tank flush system. Can be located anyplace between inlet and black tank. Required to be above the toilet level. When the thin rubber flaps stick closed, water will flood out the top full force. It will flood the entire unit if not caught in a hurry. Mine did.

Had a flood In our brand new Precept 31UL first time we used it. Tried it a second time and did the same thing. Big flood, not good. The flood and a ton of other issues with the unit forced us to trade after one trip.

Not sure of the brands we have had, but crap, our problem started prior to 2007. All those valves suck pretty much. I do what arkhillbilly does / did. External valve from HD or Lowes.
