Thanks for replies so far. To answer all of your queries- unvented cylinder, don’t have gauge at the moment-still on the old one (but new PRV labelled 3bar), blew into old PRV and was blocked-new one nothing, not checked with neighbours yet or expansion tank. UPDATE. Pressure now back, really weird. Fingers crossed! Maybe mains went low but something of a coincidence. Thanks again, PF

Hi all. I recently replaced a PRV as the old one was blocked (?). All well at first but now 2 days later we have no pressure again. Airlock? Any ideas? We have an indirect cylinder, house built 6 years ago and no problems with plumbing until now. Help appreciated. Peter F
