Plumbing water leak behind shower??

[dillon]

1987 24' Fleetwood Southwind. Normally I can have my fresh water pump on and it shuts off when it builds up enough pressure, etc. with no problem. I had it on today and it didn't stop running. I pulled into my driveway which put the RV at an uphill angle and water leaked out of the rear. I lifted the matresses and got to the water tank area and water was on the wood floor towards the rear. Everything there seemed ok when I put the pump on again to troubleshoot but then I noticed through the small opening in the wall where the pipes run through on the floor water was leaking from above in there, not the pipes on the floor. I couldn't see above there but felt the water running down the wood above the opening. I can't think of any other line that would run above but the line to the shower, it is in that area. Would I have to remove the wall to fix??

thanks for your time and any info.

Dillon some people have had problems with the shower faucets with leaks.
If your control knob is removed you maybe able to release the control from the wall so you can look behind it and tighten pipe fittings or find out you need a new faucet for shower.

I'm not sure how your unit is built, but most have limited access to the valve as well as the head connections. You can access the valve by removing the trim and yes, many shower stalls have a piece that can be removed at the head. You may not have ever noticed the head access.

my shower line from the water control valve to the shower head has a vacuum breaker installed where it will be a pita to reach. i cannot even see the vacuum breaker through the access holes in the bathroom/hallway wall but i can see the water dripping sometimes. it only leaks sometimes when the shower is being used. eventually i will have to cut a hole in the hallway wall and replace the vacuum breaker with VANGUARD fittings from lowes. vanguard fittings do not require tools to install and work with pex and copper pipe.

Not sure how you're constructed and what type of piping was used in those years. Probably plastic and may be grey pipe with specialized fittings. I've replaced a shower faucet with that configuration and it was a pain. Regardless, try to remove the fitting(s) from the front to find the source of the leak and repair it. Some plastic fittings require a special crimping tool that you can probably rent instead of purchasing. You may have to cut an access hole on the other side of the wall, but you can probably find an access panel cover (plastic) from a plumbing supply house.

On my last RV a 99 Fleetwood Flair, The cold water line fitting on the back of the shower faucet leaked. The plastic water line would slip through the plastic connector that attached to the shower faucet. I was lucky and had an access panel in an adjacent closet. I was unlucky because it happened in the middle of the night and pumped about 30 gallons into my bedroom floor and into the living room. I woke up with the pump running dry and squish squish on my feet. They make a 90 degree shower faucet connector with a slipon pushlock connector for the pex water line. If you have access it is an easy replacement.
