These test heads are on the heating zones in my house. The originals were pretty old and didn't work anymore. The plumber offered to replace them for $280 each. I found them and made them myself and saved over $200 each! Very easy to install. 1/8 turn and the knob is on top of the valve. Then simply route the control wiring to new locations on the new controller and you're done!
