Hi,
My 30 year old system has Tower zone valves. One of the valves has a sticking microswitch or faulty switch actuating mechanism, which causes intermittent problems. The problem sees to be worse when the boiler temperature is turned down.
I know which valve it is, but wonder whether it's likely to be the actual micro switch, or the mechanism which drives it, which is very crude and difficult to check.
Is there a recommended supplier for these microswitches?
Your help would be most appreciated.
