Vacuum Breaker Check Valve Location

[Toons]

I'm almost positive that the check valve for the black water flushing system is bad on my 2008 Bighorn 3400RE. After flushing the tank this weekend I found water on the kitchen floor. After further investigation I found water running down two water lines that run up between the interior and exterior walls of the camper. I can't find any removable access panels anywhere above where these lines lead. Does anyone know where can access this thing?
Thanks Toons.

Not sure about yours but I've read where many of them are behind the shower. Remove the panel that holds the shower faucet and look behind it.

If you have a 6 in screw in access in the shower look behind there. Mine was there but I just took it out down in the basement.

I'm not exactly sure, but I think you have to remove the cabinet above the toilet to access that valve.
Are the lines you are referring to located below the toilet?

Peace

I think Cookie is correct but... You can't reach the breaker from there and it's "tied" in place. My solution doesn't follow any code but I cut the pex lines and plumbed it directly not using the vacuum breaker. I have a check valve in line. The pex comes across the floor under the storage compartment under the stairs to the bedroom. You'll have to remove the basement rear wall to get access.

Just a note. I did find out the hard way that they do not like over 60# of water pressure. City water pressure at our S/B's is 110# at the street side hose bib...not the house (40#).....oooooops.

The cabinet above the toilet was the first place I looked, the only thing back there was access to some of the control panels switches. I think I'm gonna opt for Rays idea and eliminate the breaker all together. I'll just run a separate hose for flushing and unhook it when I'm finished. Thanks for all of the ideas. Toons

I found mine behind the shower valve, removed it and connected back direct. I almost cut the pex in the basement but just wanted to put my eyes on it. It had a blue pex feeding and a clear braided hose going to the tank.

I put my eyes on it, I cut the pex in the basement and yanked it out. Lol

This valve in my 2008 Bighorn blew out, and it was located up in a wall behind the toilet. Trace the tubing from the black tank cleaner water inlet. I crawled into the "access" compartment with a headlamp, large drill and a jab saw (pointed end). After a couple of hour of work cutting the subfloor next to the existing PEX line holes, I was able to enlarge the opening enough to yank out the PEX lines with the vacuum breaker at the top. I got a brass Sharkbite PEX check valve, Sharkbite PEX right angle fitting, and some PEX tubing to connect things. I got this stuff at the local Ace hardware, but Home Depot has them, too.

The water spray from the blown breaker valve also took out my Progressive Converter/Battery charger ($240) mounted on the floor under the breaker valve.

One of the reasons I remounted the converter and suppressor early on so I wouldn't experience that. Who's the engineer that decided that was a good place to put it??

I put a sheet metal pagoda-style roof on the converter.
