can anybody offer advice i have a combi boiler,but now we have to turn the hot tap on so fast to get the pilot light to come on in then doesnt allow the water to heat properly.So all we get is luke warm water and we have to boil a kettle to wash up.We seem to have good pressure but we now the flow rate isnt great.Also a very funny thing has happened to our electric shower upstairs.about three weeks ago it would only dribble out to i discovered that if i turn the basin tap on briefly the shower will rectify itself and work normally? Ican offer broadband advice but i dont know too much about boiler issues so any advice would be greatly appreciated.
