“I found that one of my zones was no longer working, and figured it was probably just the zone valve failing, as I have read many places that they die after about 5 years. Rather than calling the plumber to come and just pop a new one on, I ordered this unit, took off the old one, being sure to note the wiring configuration, and just popped the new one on myself. Rewired it and I had my heat again. Thanks Plumbing Supply!”
“My old zone valve head was acting up, sometimes working, then not. Decided to lock the zone valve in the open position & order a replacement head. New one arrived & installed it & it's working great. Found worn teeth on arm that contacts end switch.”
