“I bought this product as a replacement to a White Rodgers 1-1/4\ zone valve. The wiring required for the Taco was beyond simple when paired with a Taco ZVC. It is also the only zone valve (other than White Rodgers) that I could find in the 1-1/4\" size. Works great. Is silent. Easy install. What more could you want?!"""”
“Installed 2 of these on my boiler to separate first and second floor heating. Works fine. One did get stuck in the open position so I had to open the valve and adjust it manually. So far working great.”
