Review on 🌮 Taco 555-050RP Zone Valve Power Head Replacement Component by Viswanath Lopez

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!
