I'm trying to rig something up so I can get cold, warmish, or downright hot water in my garden hose, depending on need. I'm looking for some kind of fitting to mix cold and hot supply lines, and for the resulting mixed water to connect back to the spigot. I have PEX lines if that matters.
I've looked at using 2 valves, one on each supply line, and a T fitting. I could vary the opening of each valve to get to the desired temperature. But somehow I don't feel like this is the right way. I think opening valves halfway damages them? Also I feel that hot water could get back into the cold line that way?
Then I found this thing called a thermostatic valve. I think I can vary from getting 100% cold to 100% hot and everything in between? Or is there a safety setting which stops me from getting 100% cold or hot?
