Hi
Looking for some advice on problem with Worcester 24 losing pressure.
Boiler serviced in September expansion vessel re pressured and pressure relief valve changed by BG.
Now into December and boiler losing pressure again. Recalled BG on Friday who replaced heat exchanger and pressured vessel again. Said he couldn't do any more that that and if it continues there must be leak in system.
Pressure appears to be dropping again to have placed bag over relief pipe and appears to be dry.
Could the pressure vessel be the problem even though no water coming out off pipe.
Have not noticed any water marks on ceiling
If it is leak in system is it safe to use Fernox leak sealer as all pipework under floor boards.
Many thanks
