Does this sound like its faulty? Could it be causing my heating problems?
Quite often we don't have any hot water or central heating (like now) and after reading lots of posts I checked my motorised valve override slider.
The slider has up and down movement but has no resistance when moving it. It can be put at the top but if touched lightly falls to the bottom. Up or down makes no difference to any heating, only disconnecting the power to the heating supply for a minute occasionally makes it work again.
Thanks for any help you can give me.
