Shower Water Leak

[C Duck]

I have a 2004 Windsor 38PST with a water leak that looks impossible to get to.
The water is coming under the wall that separates the shower from the bedroom and I believe it has been going on for some time although we have just found it. At this time I can't find where it is coming from.

The wall has a pocket door in it so it is a double wall. There is a hole through the walls that gives some access to the mixing valve but it is only about 4 1/2 inches in diameter. It may be able to be enlarged somewhat. The drain under the shower is likewise almost inaccessible.

I can't tell if the water is coming from the mixing valve, the shower drain or the Pex lines or couplings.

Has anyone faced this? I'm thinking about removing the outer pocket door wall (bedroom side) which I think will open up working room to the Pex lines and the under shower drains.

I will have to have a RV Tech do this but I would like to know what he is going to have to do and be able give him some guidance from the experts.

Thanks for any help.

Chuck,

You doing Quartzsite next month?

If I were in your position, I'd turn on water pump and turn off all faucets. If pump cycles on/off, you know the leak is likely fresh water side, (the valve). If it doesn't cycle, more likely drain or something else.

You can possibly look through those 4 1/2" holes (flashlight) and look and see if the PEX to shower valve fittings show any signs of leaks. They came from factory only hand tightened.

I had a water pump go wacko a few years ago and did not shut off. Built up pressure in PEX until it busted the plastic fittings between the PEX and the shower valve in the wall. A real pain to fix it, but it's doable.

I had a leak in exactly the same place, and what was puzzling was I never would have known about as it only leaked when the shower was being used. It came out of the mix valve connections. I used the opportunity to replace the mix valve and all connections at the same time. Open up the access and watch for a leak when the shower is on. Could be the same issue.

Is it possible that the washing machine water lines runs through this area if so turn them off at the main valve and see if the leak stops

Hi Bill...

Thanks for the reply and I will try your suggestion.
As for Q I won't be able to attend. On our last 2 month trip our house flooded before we got home. My son got the abatement people in there and they removed ALL the cabinets that touched the floor, cut the sheetrock up a couple of feet throughout the house Etc., Etc. We are now living full time in the MH and dealing with the rebuild.

Thanks. I will check for that.

Didn't think of that either. Thanks.

Sorry to hear about that. A flooded house is no fun. Let us know what you find out about this leak.

I'm now trying to figure out if my bedroom pocket door wall can be removed to give access. It's a double wall with the door between and I'd like to remove the wall on the bedroom side (the other wall is on the shower side).
Any ideas?

does your bedroom carpet go UNDER the wall and pocket door?

I replaced my bedroom carpet last year. My carpet goes under the pocket door, so I had to remove that wall and the pocket door. Not particular difficult, but time consuming.

You need to remove the pocket door first. Pull it all the way out, and look for 2 handles on top of the door. Pull/push those and it will release the locks off the rollers. Then you can pick up door and remove it off track. (you MAY have to remove some facia trim to access the top track, locking mechanism and rollers)

Once door is removed, you can look inside pocket and there should be some small metal angle brackets that connect wall panel to floor. You need to reach (way easier said then done) in there and unscrew those brackets from floor. (there could also be a bracket or 2 screwed into back wall and possibly even on the ceiling)

Once that is done, the outside panel will come out. If it's sitting on your carpet, it's in there tight.

Removing a wall would be my last resort!

Wouldn't be surprised if it simply loose connections. Happened to me with my National RV.

I agree, but if the water leak got the carpet wet, I'd remove the wall and carpet/pad.

Thanks Bill, my carpet does go under the wall. I will save your instructions for the tech. We've yet to find the leak and I was hoping the wall removal would give more access to locate it. Funny though, the leak seems to come and go. Sometimes it soaks the carpet and at other times it doesn't. Nothing I do seems to repeat the leak, at least at it's worst where it would be easier to find...I think.

I have tried to tighten all the connections I could find.
Thanks for the reply.
