Review on 🌮 Taco 555-050RP Zone Valve Power Head Replacement Component by German Diaz

I replaced one last year after 20+ years of continuous use. It's time to change the second. Just turn off the circulation switch on the boiler. Turn 1/2 turn to remove the old valve and leave it hanging by the wires (its indicator). Install the new valve BEFORE connecting it. 1/2 turn to secure. Then move the wires one by one from the old to the new valve. All you need is a Phillips screwdriver. The old one lasted more than 20 years, I hope to get the same results.
