Shower Control Valve Froze and Cracked over the winter months.

I have a 1976 Overlander with the rear bath and a cracked shower control valve. This problem is from not removing all the water last fall. Is the only way to get to this control valve by removing the external skin and coming in through the side of the tralier? I can't seam to find an external access door that will gain access to this part of the trailer. I really don't need the shower but I can't seam to find a way to turn the water off to the shower so I can't use water any where else in the trailer until it's fixed. Any help or suggestions with this problem will be most appreciated.

broken shower control valve

Mountainman1
Sorry I can not help you with your access problem to repair the broken shower control valve. To avoid future winterizing problems you should consider using a combination of compressed air and RV antifreeze. This may require you to install a RV pump converter winterizing valve . Here is the checklist I use when winterizing my trailer. Hope this helps.

You may be able to get to the bad parts by removing the handle, trim ring, and mixing valve. Be aware the plumbing is soldered copper back there, be careful when trying to repair it you don't set fire to the shower pan/tub assembly.
If you can't get to it to fix it that way, your choices are limited to removing the tub assembly to gain access, or removing the outer skin. There is no access hatch.

If your 76 is like my 73 ,with the valve on the back wall,and a shelf over it you remove the shelf,seems like a few screws and rivets,that will give you access to the valve .Sweat it out and install new valve.My 77 faces the back and is accessible thru the back hatch.Hope this helps.Dave

I think the valve is oriented a bit differently on a '77. The older coaches had the valve against the side wall, rather than the rear.

If it has the small cover plate on the curbside wall,then pull the shelf above it and it can be accessed .Dave

Well no one has said it yet, so I will. Do Not Remove the Skin. Access from the outside it not needed. Pull the handle and cover plate, it is tight but most valves can be pulled that way. If you can't do it, the first thing to do is buy a new replacement valve with a bigger cover plate so that you can enlarge the opening to help in removal of the old valve. It will work.

Garry,
Our '74 Sovereign (Mid bath) has a frozen (burst) control valve. I'm planning on replacing with a new control valve from the local hardware. Have access from the cupboard under the sink. I had replaced the copper with Pex last winter but didn't realize the shower valve was toast.

If the 76 is like the 73 it is a small plate in a recess,a bigger plate will not fit,even if it were on a flat surface no one makes a plate big enough to work thru ,unless you buy a moen repair plate that goes behind the faucet trim.REMOVE THE BACK SHELF. Plumber Dave

My 1972 was accessible by removing the vinyl trim (rivet cover), removing a few rivets and then I had access from the inside. It's tight, but can be repaired.

Thanks to everyone that made suggestions to help. Access was gained by removing the bottom shelf in the bathroom cabinet above the shower control value. The problem was not a broken shower control value nor a broken water line. It turned out to be a popped loose hose clamp that was clamping a plasitc water line to a copper line.
