Mixer valve? When you bought the home, did you have a plumber go over the system, or did the Home Inspector make any mention about a circulation system for the hot water, that looked odd to them in their report?

If you want to experiment, go to to the water heater and shut off the cold water valve to it, and then run the water for say five minutes, and see if the temp changes, or pressure changes.

Hi Ben,

I was surprised when I saw you thanking Greg for his post that attacked me. It was so unlike you from all the posts you've made in the past, which are very knowledgeable with no offensive tones. Thank you for taking the time to clarify the mishap.

Best regards,
HRG

These single handle valves are controlled by a single internal cartridge that blends the H&C water as you adjust the control handle. They sometimes fail allowing hot water to pass through the valve and mix with the cold water- even in the off position. Your symptoms indicate this maybe the problem. It's easy to fix.

Could be failed washing machine solenoids as well.

Try shutting off the washer hookups.

Okay, I think we're zeroing in on Malinda's problem, so.....

The first year we were out here in BFE, I worried the well might freeze up, so I put a space heater down there to keep the pipes (and pre-charge tank) from freezing. Of course, I had it thermostatted to around 45-50 degrees so it did not run constantly...... anyone see where this is going? When I lifted the absolutely snow free cover to remove the heater with the failed thermostat, it was like an oven down there!

But it does it from all faucets including the dual control ones.

If the single handle faucet is leaking hot across to the cold line then all the other faucets down stream and maybe some up stream would be warm since your cold water supply would be drawing hot water thru the leaky valve.

When looking at the hot water heater, the cold inlet should be the one on the right, generally it's the only one with a shutoff valve.
