sewer flush water leaking inside
When I last used my sewer flush, water started leaking down the corner of the shower enclose, down the steps and underneath the outside left corner of trailer. When I pulled the pocket door out there was water on the door. Pocket door butts up against the shower enclose and not accessible from that side. Took the faucet down from inside the shower and could not reach up inside far enough to reach where water was coming from. A person from Camping World said there was some kind of cap or fitting that was causing problem. Looks as if the shower enclose will have to be removed to reach the problem. I have extended coverage, so hopefully they will cover the problem.

The anti-siphon valve on the black tank flush line has failed, either because it was not winterized properly and it cracked after it froze, or sometimes they just plain fail. It is a cheap, plastic unit.
There are many posts about it, with a few different fixes for the problem.
Once you locate and access it(some are easy, some require cutting an access hole in the paneling), you can replace with same crappy valve, or upgrade to a different type of valve, or just plumb it straight through with a high enough loop and put an anti-siphon valve at black tank flush connection point in the convenience center.

mine is located in the same place as yours and a stink bug Got inside the cap which wouldn't allow it to seal when the water pressure was on.
if you take the side panel off of the convenience center in the basement you will see the two pipes going up behind the shower. I cut mine there and removed the valve and used 2 shark bite elbows instead of the valve.

I have the same unit as you only a different year. Mine has an access panel on the back wall of the cabinet on your right as you enter the 5'er. Close the pocket door, remove the panel and you should either see the check valve or reach in and feel around with your hand. Once you locate it cut an access hole and make repairs. Mine has not failed but if it does I'll remove it like Oldelmer1 suggested. SReigel published some pictures detailing his location and cutting the back panel of his closet. I'll try and find that and post it also. Jim

Thank you for the replies. Looks like I might have to cut access door in the cabinet above TV.

Different model, same basic location and leak problem. I have a coat closet just inside the entry door that backs up to the shower with the pocket door in between. There is an access panel in that closet but the valve was not behind it. But I could reach in and down a little and feel the valve. So I cut a new access hole there.
Initially I ordered a new valve from the original manufacturer. But when it arrived I could see stress cracks all around the perimeter of the plastic valve. So I sent it back and, like others, just used new fittings to eliminate the valve.
Here is a (somewhat fuzzy) picture of the closet. I used some narrow trim wood, cut it like a picture frame, stained it, and used it to reinstall the piece I cut out. Looks like it was made for it. Don't have a picture of the final product though.

Mine is located between the pocket door and the shower enclosure. No access panel of any sorts. Bad planning by Keystone AGAIN! As suggested, I can either eliminate the valve completely by adding 2 elbows and a short piece of pipe after cutting out the valve, or cut an access door in the back of the TV cabinet and put in new valve. I have extended coverage, so will see if they will repair, and if not will probably just eliminate the valve.

You may need to remove the pocket door so you can measure exactly where the valve is located. You do need an opening in the location of the valve and large enough to get both hands in to remove the valve and install the new valve or new fittings to eliminate the valve. The picture is of the two pipes after I removed the valve and before I added new fittings to eliminate the valve.
If my pocket door were open (i.e. inside the wall) you would not be able to see the water lines in the picture above.

Same thing happened in my 3400RL and it's located in the same place. I was able to take the shower faucet loose from the shower wall and fish the water lines to the black tank flush through the opening. I had to reach in the opening to the right and took a bit to get it through the opening but was successful. Ordered the vacuum break/check valve from Amazon. If this happens again I'll just connect the two pieces of Pex tubing together and not worry about it anymore. Tim

When I had to cut a hole in the back of our pantry to reach the valve in our 3400, I called Keystone and asked if they could send me a matching sheet of paneling to make an access cover. They did, free of charge. I cut out a square piece and glued velcro on it and it is virtually invisible.

Our 06 3400 was in the pantry cupboard behind a access panel but when I removed the panel there was no valve. Seems either the panel or the valve was in the wrong place as the valve was about 8 inches to the left of the panel, nice work. We cut a bigger hole to replace the valve with a better quality valve and covered the extra big hole with shelf paper.One of those little things.

To date I have not had a problem with the check valve for the black tank flush line.
Just a suggestion. I went and bought a brass one, check valve, and using a short jump hose connected it permanently to the convenience centre flush fitting. That way the valve is front and centre, not buried, and the short hose makes connection quite easy to the flush hose.
I'll deal with the buried valve when I have to or maybe before it causes trouble.
This way any chance of backflow is prevented and that is what the buried valve is supposed to do. It is thee for a good reason.

Was that the only way you could reach the valve? By cutting through the pantry?

As long as you cut & splice the right lines, this sounds like a great idea. Just don't forget to install an anti-siphon fitting at the black tank rinse connector in your convenience center.
Less effort, same result.
