“I zoned my 3-level house with these valves and they work great. The only issue is to make sure which type of thermostat you use if you are also using the TACO zone valve controller. I used Honeywell round stats and learned they were "power robbing" which required additional transorbs to make everything work properly.”
“Taco makes products that replace this but when you're doing repairs the original product is much easier. These valves were very popular. plumbing supply and more had it in stock and shipping was fast!”
“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.”
