I can't see any water coming out of the pipe outside . Would it be expensive to get a preasure relief valve replaced ?( this may be realy stupid but could not having the plastic caps on the rad valves lose water ?)
between £50 and £70 pound, but if its not leaking then you wont need it replacing, have you checked your radiator valves? if it only needs repressurising every 2 months then it will only be a small leak.
I've checked all my radiators and non of them have the slightest leak . Is the only way to check all my pipework under my floorboards or can a put something into the system to fix the leak ? Thanks
