Help me identify this part
Bought this a long time ago online and now it stopped working and I cant find it again.
It was called a solar TAV valve, used for solar heating panels or garden hoses in the sun.
Basically the idea was that you left the panel or rolled up hoses in the sun, and as the water temp rose and hit 90, the valve would open and let the hot water into the pool and then shut when the cold water hit the valve. This was supposed to happen over and over in a day so that only warm water was allowed into the pool.
It looks to me as it was made with 3 pvc pieces. An end cap with a hole in it, a coupler with the temperature vave in to, and a last piece that has the female end of a garden hose connector in it.
I would like to make one myself, but Im not sure where to get this valve or what its called. It looks like it "pops up" when warm/hot water touches it. The piece with the garden attachment says lasco sch 40 1 1/4 x 3/4
