I got home this evening to find that the central heating wasnt working. After some investigation it seems that the 3 position valve isnt working.
Normally when I switch the CH on the valve whirs into the mid position (it has a small window on the side so I can see what position it is in), but its not moving at the moment, and the radiators remain cold. It has a manual lever on the side, and when I use this to move the switch the mid position, voila - hot radiators.
SO my questions are:
a) is it ok to leave it in this position? b) is it easily fixable?
The valve is a Tower MP3-22C
ANy help would be gratefully received.
Many Thanks
Paul
