Hi guys, my plot has thickened once again. My new question is: I have a taco zone valve that is stuck open. I take the head off and the piston is corroded in the open position. The other zone does not get heat at all. I swapped the head and still no change. Is there some kind of safety that only one valve can be opened at once? Also the heater is constantly firing and the circulator always runs. Should this be happening? I'm hoping to change out that valve this weekend but will that solve the problem? The valves are wired in series. As always thanks very much for any help.
