Seat fail in 3+ years
The seat assemblies start to leak after 3+ years. I believe that the copper bellows that keeps the piston watertight just starts to breakdown. Taco fails to redesign it. The assy. costs as much as the valve, so if you get the whole valve and take out the seat assy., you must recycle all the brass on the outside. It's a poor and costly design and not worth the trouble for the long haul.

Cheaper than the rebuild kit.
Had a zone valve fail. Hot water was circulating in this loop when any zone called for heat. I bought this just for the inside valve. I am using the valve, spring and motor. It cheaper than the rebuild kit.

Worked like a charm
Exact replacement for a 30+ year old one that was sticking. No fuss (well, sweat soldering is not a lot of fun, but that's not the valve's fault and I wanted to not change things up since I'll possibly replace the aging furnace next year anyway).
So if another one sticks, (I have 4 zones) I'll buy it again.

Q: I have a three Taco 571-2 zone valves. Can I attach two different thermostats to one of the zone valves? I added another room to this zone (new addition) and would like the heat to come on when any of the rooms call for heat. I know the other room's heat will also come on. Will the addition of another thermostat cause conflicts on the controls if I attach the thermostat wires to the same screws on the zone valve as the other thermostat? Ray M

Verified Reply- PexSupply StaffNo, each zone valve can only accommodate one thermostat.

Q: I have a Taco RMB-1 how many zones can be hooked up to block?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe RMB-1 can handle as many zones as its 008 pump can accommodate. They must first be wired to a zone valve controller.

Q: My heating system has three zones. All three zones are using 571-2 zone valves and are all wired the same. Two of the zones work fine. The third "short cycles" meaning that when the thermostat requests heat, the zone starts and then stops repeatedly. The start is for about 3-5 seconds and then goes off. About 5 seconds later it starts again. This goes on continuously unless one of the other zones calls for heat, then the furnace runs fine. I tested connections 1 and two and got 23ohms between them and have replaced the old thermostat with a new digital one. Suggestions?

Verified Reply- PexSupply StaffIt appears that you either have a short in the wire or the power head needs to be replaced.

Verified Reply- PexSupply StaffIf you are registering 24 volts with a voltmeter, it is probably a wiring issue.

Asked by tom 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe best way to determine whether or not the valve is wired up correctly would be to make sure you are certain of where each wire leads. To wire the valve by color is probably possible, but it is better to do it with certain knowledge of what goes where. You can determine whether the power head is working properly by removing the wires from screw terminals 1 and 2 and taking an ohm reading across them. If the reading is not between 18 and 23 ohms, the power head likely needs to be replaced.
