How did the vinegar treeatment on that frozen check valve work?

[lyncjim]

I put lime away in small container and put the dis assembled mixing value in the container. It remove all the lime.

Lyncjim,

Have you had anymore trouble with that mixing valve?

[lyncjim]

No we have camped about 5 or 6 weeks and is working fine. I also added ball valve in cold line feeding the mixing value. If I have problem I can shut valve to limit amount of cold being mixed.

That's encouraging. I got mine working by just working it open and closed a few times. I fixed it but then winterized shortly thereafter. The internet problem reports seemed to indicate a correlation between winterization and mixing valve problems. So we'llI see how it goes next Spring.

It seems to have worked. I say "seems" because pushing the valve in a little with the tip of my small pocket knife it seems to bounce back against the seal properly. However, if I push harder on the valve, it sticks. Took a chance and reinstalled it and tested it with water in my empty antifreeze jugs. It seems to have worked fine; no more leakage through the water heater drain plug and no other leaks. So I went ahead and winterized it with antifreeze.

As I always tell my wife when I fix something, "GENIUS" !!! Thanks for the troubleshooting, diagnosis and fix. That was a tricky one with all of the 3 valves to check out.
