“I did not need this but wanted to have a replacement should I need one for the ones I have that have been running perfectly for twenty years. Taco is the leader in zone valves in my mind.”
“This was a simple, inexpensive fix. After 15 or more years, my first floor zone valve was inconsistently failing to respond to thermostat stimulus. The same thing happened 2 years previously to the second floor valve so I understood what was wrong. After turning off the furnace switch, I removed wires from the old valve power head. I removed the old one from the pipe-attached valve with 1/4 turn to the left”
“Bought as replacement for a Taco zone valve which had burned out. I have had a number of Taco zone valves fail over the past ten years or so. In my opinion their electrical quality is slipping and if my job was being installed new, I would probably use Honeywell zone valves instead of Taco”
“Amazed that someone had an exact replacement. Thought I would have to buy the entire zone valve, Expected an after market replica, pleasantly surprised to get the real thing. Switched the oil burner off, removed three wires, twisted on new head, and it works. I bought three, at this price, about the same as a single complete valve at a big box store.”
“When the thermostat in a room or on a floor calls for heat, this is the item that opens or closes the valve that controls the flow of hot water from the boiler into the radiators. It's one of those things that you will remain unaware of - until it fails, and you're getting cold. The original lasted about 15 years”
“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.”
