“I used this unit for parts to convert my old Honeywell Zone to a replaceable powerhead zone valve. The pipe/valve portion are the same and this is an easy way to upgrade an old boiler. Only a screwdriver needed. I am very happy with it.”
“I had 4 new valves put in and one of them "Stripped" the insides out. The gear is plastic from what I was told. Plastic...really??? It cost me a valve and a plumber call to fix the issue.”
