Hi,
Recently had a full service, new seals etc. on our combi boiler, it's a Vaillant I think. Everything fine. Located in the kitchen.
At the end of the kitchen we have the bathroom. Also have a toilet and wash basin upstairs.
For some reason the hot water pressure on the hot tap on the bath and the wash basin in the bathroom is ok, then goes off to a dribble then nothing. Wait for some time and it will build up again, then go to nothing.
The hot water in the kitchen tap and the wash basin upstairs has good constant pressure. Just the bathroom, which is around 15ft from the tap in the kitchen and 12 ft from the boiler.
I'm racking my brains!! Can anyone help? Thanks.
Rob.
