Hi,
My central heating system is just over 6 years old. I have just replaced the myson 2 port zone valve actuator for the third time. I had to replace the first one just over 2 years ago. i.e. 3 replacements in two years. Is this unusually excessive failure? I did check that I could rotate the spindal on the actual valve by using my fingers. It is stiff but I didnt need to use plyers or anything. Have I just been unlucky?
Thanks.
Steve.
