The pressure keeps dipping on my Baxi Combi Instant 105e. Last time it dipped so low it conked out. It's starting to slide again but as the engineer who came didn't seem to have to do a lot to get it sorted, I wondered if it was something I could sort myself - is it just a case of turning a tap somewhere? If so, could anyone tell me which one?
Cheers for your help
