hello all, we have a combi boiler that was recently serviced by BG (pressure adjusted from being very very low) and since then the boiler won’t fire up for the shower (mixer, all parts hidden by wall). It will fire up for other taps in the house (kitchen and bathroom too) and interestingly it was also doing it for the shower hose accessory with hand held shower, but not the main shower head. Now, our shower had been leaking for some time, we believe it to be the cartridge leaking, boiler engineer says he thinks it’s the showers fault as hot water is reaching everywhere else.including the shower hose with small handheld shower head.
now we’ve just had a plumber come and take the old shower out, break the tiles and put in a second hand T bar shower and he’s connected up the old shower hose and small hand held shower head so water comes from there and not the main shower head. Leak has stopped as it’s a different shower. As above, the hose and hand held shower head was working to fire up the boiler, but clearly only when connected via the old shower system as, now we have the same issue. hot water won’t come on through the small shower head (the only one we now have) unless we turn on bathroom tap to full blast hot for a minute or so.
Worth mentioning that hot water is fairly slow to come to any tap but boiler won’t fire up at all for the shower. But once fired for something else, we get hot water there.
bg engineer coming back tomorrow with a new hot water exchanger but I feel its a boiler issue given timing of the issue and something to do with the pressure. I don’t want them blaming the shower if it’s not the shower. We are getting the whole bathroom revamped in August but obviously this is a problem we’d like to resolve.
Any thoughts? Thanks in advance
