I'm new to the site so please bare with me.
I've got a worcester bosch 230 boiler which is losing pressure. (I know it's a bit long in the tooth but it generaly works very well!) I've checked for leaks and also ensured there is no loss from the relief valve. However when I checked the expansion vessel there was no air in it, also there was no water coming out of the schraeder valve so I assume that the diaphragm is not leaking. I repressurised the exp. vessel to 0.5 bar and a few days later the pressure had gone. Could this be due to a falulty schraeder valve? and if so can they be replaced?
