Hello,
Recently changed bathroom sink taps only. Turned off the cold mains, and turned off the gate valve at the hot water cylinder in the airing cupboard. Replaced sink taps in upstairs bathroom, turned on the mains and the gate valve at the cylinder. Now have a poor flow from hot tap downstairs, upstairs there is an initial flow of water from bath and sink taps, but then it dies away.
Thanks
