“I have a 3 zone gas hot water baseboard system in which the 3rd zone was not working, fortunately for me I was able to diagnose the problem and order the Taco 555 and paid far less here than anywhere else and also avoided a very expensive service call.”
“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.”
