Find that leak

When using the black tank wash connection I found a leak. It is not at the entry connection. The line goes straight up into the floor and the water is dripping back down the line from somewhere up there. It is also dripping onto the heater.

Anyone have any idea if there is another connection up there which could be the leak area? Or maybe the line ruptured?

Any help would be appreciated.

Its the vac breaker installed in the rinse line. If you have four pex lines under your bathroom sink, it is high in the back near the underside of the faucet. It unscrews, is plastic, and cheap. Use fittings to connect the two lines back together. Install better vac breaker outside rv in rinse line going to the external connection. Life will be better. John

All I have under my bathroom sink is a hot and cold line coming in. Mine must be somewhere else.

Look to see if there are 4 lines going up to the shower. Mine (different model) was in the wall between the shower and entry closet. 4 lines going up, 2 for the shower and 2 to the antisiphon valve.

Some have found them under the sink, some behind the shower, some behind a pocket door and others behind a kitchen cabinet or pantry. Depends on model where they put it.

Found it. It is behind a cover in the pantry. Unfortunately they put the hole above it making it very hard to reach. Guess I will be making a bigger hole.

Same problem I had. The plastic cover was not in the right place. So I reached in, felt the valve, and estimated where to cut a new hole. This is after I eliminated the valve.



Then I used the cutout piece with a little trim wood to make a picture frame, and it looks like it was made that way.

I have developed a spray of water between my sliding bedroom door and the back of the shower when I connected unregulated water to my black tank flush system. I can see a valve behind the sliding door but can't get to it. Any suggestions. Is that an anti-siphoin valve that I broke and or line? How do I get to it?

I just found out I have this leak as well when I connected the tank flush connection. Question. If I am not using the tank flush connection is it still leaking or does the leak only happen when using the flush connection. Don't want to curtail the weekend expedition. thanks.

Dave- see my pictures above. That is also the wall behind my shower and where my sliding door goes in. That is looking thru the back of the cabinet above my entry closet. If the door were pushed in you would not be able to see the pipes. The white plastic cover was install during manufacture. But it is in the wrong place to access the valve. I had to reach in, feel the valve, and make a guess about where to cut a new opening.

Almost for sure the valve leaking based on everyone's experience.

I answered your question in the other thread also. But no, it will not leak unless you are actually using it.
