Review on 🌮 Taco 555-050RP Zone Valve Power Head Replacement Component by Chucky Hepler

This head is easy to install if you have access to it. Just remember to lower the temperature on the thermostat to avoid overheating. Before disconnecting the cables, the power supply to the power head must be switched off. Be sure to replace the wires the same way you removed them. Also, the manual control lever on the power head must be in the up position as shown in the illustration before the power head is removed. The work took about 15 minutes.
