Having had very small trickle which then stopped altogether in bath cold tap only ( this happened every time it was turned on)
The bath system is gravity fed from attic header tank. At this time all hot taps were flowing fine.
This appears to have been solved by replacement of tank in attic and removal of a gate valve on the cold system. However , now all hot taps in house are now running very slow( they never actually stop flowing )
Any ideas ?
