It's been suggested previously to make sure the winterizing bypass is closed and the outside shower valves are both closed. Also, if your shower wand has a positive cut off, make sure that the shower valves themselves are both closed.

Also, some water heaters have a mixing valve. The idea is that the water is heated to a higher than normal temperature (which effectively gives you more hot water); when there is demand for hot water, the valve mixes some cold water into the hot water supplied to make the temperature safe. If that valve is messed up, you could get water temperatures that are odd.

Question

Well, we checked all the valves and they are all done correctly. Any other ideas before we assume it is something wrong with the mixer valve?

Wow! I just discovered the same problem but it's only our toilet water... I ran it for a bit when sanitizing it and steam was coming out! (It's Colorado and chilly at night) Steaming toilet... I'm sure you guys will have fun with this! I just assumed the toilet was accidentally hooked up to the hot water supply -
Any ideas my friends of the Jayco Forum?

Maybe he was washing his hands in there after he was done with his business...to save water of course!!

Is it possible to have an air pocket and pressure build up in the hot water tank? Can that pressure push hot water into the cold lines?
I experienced this too on our last trip out but didn't really investigate it further.

When the hot water tank get to hot it backs up the cold water pipe .Thermostat set to high or not working.

I will have to keep an eye on this during our next outing to see if it happens often. I only noticed it once before from the bathtub faucet.

You can see the steam rising when you flush....

It is possible that you have a cold water line running right next to the hot water line and the hot water is warming it up in that section of pipe.
