    Black Tank Washer Breaker Valve

    Gang:
    My black tank washer seems to be plugged up. I worked on it in early June after the atmsopheric check valve blew apart under high water pressure. Since I was on the road, and didn't want another plastic valve that would blow up again, I installed what the local Ace hardware had that was fitted for 1/2" PEX - a regular brass check valve.
    I was shopping at my local independent RV parts tore today, and looked at add-on black tank washers looking for the atmospheric valve. What I noticed was that NONE of the 3 systems I looked at had a breaker valve (and no visible check valves). It has been posted here that it is a plumbing code spec that these atmospheric valves be here and be located at a highth above the highest black drain. I suspect my inop washer is due to the check valve being jammed. So the questions are:
    1. Am I supposed to be using what they call an "atmospheric check valve", and where do I get a GOOD one with 1/2" PEX connections?
    2. If the aftermarket kits don't have this check valve, why not? Is this really legally required?

    Here's a link to one of the aftermarket rinsers: http://tweetys.com/tornadorotarytankrinserwithhose.aspx

    Took mine out and left it out, no more chances of a leak.

    Re: Black Tank Washer Breaker Valve

    Mine broke an caused water to go into the area behind the toilet. I tried to get it out without opening up the wall. No luck. I cut the Pex to and from the valve and put a brass coupler in line and it works great with no problems.

    Re: Black Tank Washer Breaker Valve

    Gang:
    I did some more internet research on trying to find info on the original installed system and came up with this link from another RV forum: http://www.bandbmolders.com/files/Ta...tructions2.pdf .

    I noted 2 critical items in the flusher instructions - 1) No maximum water pressure to be applied is stated in the literature leaving them open for claims. 2) If you read line number 7, it would seem that Heartland might be at fault in where they installed this device directly above the 12 volt convertor device ($230) in my coach, and those built about pre-2010. I am not sure what conditions would cause the discharge of fresh water from the valve's atmospheric vent, but this line in the instructions seems to indicate this may be a not an abnormal occurance. Maybe this explains some of the mysterious accumulations of water in the storage compartment people have reported.

    I keep an eye open for leaks from mine. Any sign of a leak and that thing is coming out. Its right behind the shower service port. Probably should just eliminate it anyway.

    Re: Black Tank Washer Breaker Valve

    Bill, on your original post with the link to tweety's, that tank rinser has a back flow preventer built in. I had installed one of those on a previous trailer we owned and it seemed to do a good job. Never looked inside.

    Re: Black Tank Washer Breaker Valve

    Another note about the black water tank rinser system and leaks. On my 2013 Torque 321 I found the system was not working correctly due to a kinked line in the pex line between the atmospheric valve and the rinse head in the tank. I corrected the line issue and tried the system again and was disappointed with the leakage of water out of the atmospheric valve directly over all the electronics. I will be re-routing the system piping without the leaky atmospheric valve. I can install a check valve and vacuum breaker in a more suitable location than over electrical controls.

    Re: Black Tank Washer Breaker Valve

    I too have to replace the atmospheric vacuum breaker/check valve on my '08 Sundance 2900RK. I called B&B Molders, the manufacturer and they are sending me one at no charge! My only other issue is where to find the valve. Any ideas where the valve can be accessed on my rig-its a 29 ft. rear kitchen model. many thanks!!
