Water valves – repair, o-rings, and replacement

WaterValve_2These valves are used on my Coachman Mirada for the water panel and also the water heater bypass.

On another forum,  someone was having problems with the water handles leaking, so I took apart one of my broken ones to see how they came apart and also to see if they could be repaired. i.e. new o-rings, etc.

1) Pull the handle straight back to remove it. They are hard to get off, but they do come off.

2) With the handle off, push on the handle stem, the innards will push out the back of the valve body.

3) Look at the 4 o-rings, they seem to be standard.  The two larger o-rings seal the ends of the operator,  the two smaller o-rings seal the actual valve opening (the part that turns the water on/off.

I haven’t found any source for the valves,  If anyone finds them,  please post a reply

4) When you put it back together, slide the innards back in to the body

5) Push the valve handle on the stem. It only goes on one way, make sure the indents on the handle line up with the indents on the body (the indents keep you from turning the valve more than 90 degrees.

You may need a helper to hold the innards from being pushed out of the body.

The valve handle should be snug, Pushing / pulling on the handle should NOT move the innards back and forth. If it does, the handle isn’t seated all the way on the stem.

  1. Great write up. I had this issue happen this weekend. I started to fill the water and noticed water coming from the panel. The valve was coming out of the holder anytime I turn the valve. I assume the o-rings are worn out. Any idea what size them O-rings are?

  2. How do you get at the valves? I’ve tried to take the plywood panel off but the valves seem to be fastened to it.

  3. On mine, I can get to the back of some of the valves by removing the bed mattress and the panel the mattress sits on. I can’t remember if I can see the valves from inside the bed side cabinet.
