I have had my cental heating for aprox 7 years, during which time the 3 way valve has been replaced twice, it now seems to have gone again, I think that the guy that installed and services it has not put any inhibiter in, the problem is that the radiators come on only when the hot water comes on,[which is what happened the last time] would putting inhibiter in now, going to free it up, [if that is the problem] or is there anything that would free it, or will the whole or part of the valve need replacing, and then inhibiter added? I would appreciate any help as this has cost alot of money
