“These things are super easy to replace. I had a zone which was not responding to the thermostat, and realized it was the zone valve. First, you can open the broken valve by switching it to manual, but then heat will go to that zone if any other zone calls the pump - good if you need heat in that zone emergently. Ordered this replacement, and the instructions must have been written by someone in 'Merica because they were actually readable - take the power off the valve, remember the order of the wiring, wait 5 minutes, twist and lift the valve off, place the new valve on by pressing down and twisting, attach the wires in the same order, and bingo, you got a zone valve! Just remember to keep the switch on auto.”
“A Must Have Backup Replacement for your heating system for the winter - don't get caught without spares! .... As simple to replace as a light bulb -- an old one WILL burn out (like a light bulb) after years of service. Quality is great - heavy duty (my old one lasted ~ 7 years before burn-out).”
“Easy to install, exact fit replacement for my zone valve. Since I have 4, I'll keep one of these on hand as a ready replacement. The one I replaced was 20 years old.”
