“Recently discovered contact switch of zone 2 not working resulting in having to activate bypass of zone 1 to get heat upstairs. Ordered and installed new zone valve and everything and everyone is happy not to mention not having to heat first floor unnecessarily at night. I ordered two. One is spare. No pipe sweating needed this time as it was easy to detach the motor head and electronics piece from brass piece. Fast delivery. I would recommend this company to everyone.”
