Thermostatic Mixing Valve

December 11, 2020. This is a thermostatic mixing valve, the last bit of plumbing from this week, It began with cooler hot water, then was a leaky hot water tank, and finally this repair. I had honestly never heard of a thermostatic mixing valve before. But now I know all about them. I also did a Lightning Talk for a Creative Commons series, along with a couple of meetings. https://flic.kr/p/2kggANt
