One way valve on hot water in shower

That’s exactly what I love about mine. Once the hot water reaches the valve, it will maintain the temperature you set with the temperature knob. And, it will react very quickly to changes in the water temperature as you turn it off and on with the shower head. It won’t scald you, and until you run out of hot water it won’t freeze you either. I keep the temperature knob on mine up against the red override button. If you go beyond that, it can get pretty hot.

When you’re trying to save every drop of water you can, part of the problem in my camper was the cheap plastic faucet itself. As the faucet warmed up and cooled down from the water flowing through it, it was affecting the hot/cold mix adjustments, and I was having to fiddle with it too much. Time spent adjusting the water temperature is time and water wasted.

If I’m ever in an extreme water conservation setting and don’t even want to waste the water that’s lost waiting for the hot water to reach the thermostatic faucet, I can just catch that first bit in a clean container and dump it back in the water tank after showering.

Sorry to see that the first one was defective for you. I may have been lucky with mine, but its given me no problems. I tried to make it clear in the topic I posted the link to that I wasn’t really recommending THAT particular thermostatic mixing valve because of its unconventional installation requirements that worked for my camper, but I was 100% recommending a thermostatic mixing valve. I hope you have better luck with the second valve.
