Our Central heating/hot water is misbehaving - the radiators are getting hot with the hot water on.
I have got as far as working out that it is a problem with the three way Honeywell valve and that when set to Hw only the lever on the side is floppy (I read it was supposed to have some resistance).
Does the whole valve need changing or is there anything servicable inside?
