Anti Scald Mixing Valve
Just now I checked it was 110F which is a good temperature, but other times it's lower than that. They demonstrated that the hot water coming from the heater was fine (pipe was hot to touch), but that the pipe that distributes to the rest of the house was much cooler. They said it was a problem with the mixing valve and required a replacement which wasn't covered. So my options are look for a plumber, or try to fix this myself. I've watched a few videos on youtube and this repair doesn't look too bad. In some cases, maybe just washing the inside, getting rid of scaling by soaking in vinegar for a while might even fix the issue. If not though, I would need to buy this valve, and this is such an obscure product there aren't many reviews for me to have an informed opinion. Here's where I'm looking for the community of DIYERs here to please recommend me which valve (brand name/model/features to look for/warranty) to choose. Also please stop me if you think this repair is too risky and I could mess something up real bad to try and save maybe $3-400.
