I have a 'back boiler' within my chimney breast.
I had to turn the water mains off the other day (which I have done before with no problems) as soon as I reconnected the water after doing no work the cold water is flowing fine but the hot water is fine for a few seconds but then dribbles.

Please help as I do not know what to do

    I don't know what to do either, I've never heard of a Back boiler ( back breaking boiler yes ) or a chimney breast.

    How about some more info ?

    I remember those.

    I would venture a guess that you are from the other side of the Atlantic Damien.I have yet to come across a back boiler over here. I would also venture a guess that yours is a plumbing problem - you have an obstruction in the hot side in which the pressure builds when faucet (tap) is closed. Will run fine when first opened but slows due to restriction. Call a plumber!
