do you have water tanks in loft or airing cupboard? these will be removed with a combi they can then join supply to bathroom & kitchen from combi for hot & and your cold from mains supply if not already???
Hi
Yeh I have a water tank in the airing cupboard...they did say that will be removed along with hot water cylinder I think.
I think the supply in bathroom is not from the mains...the cold water in kitchen definately has good flow....I’m assuming that is the cold mains as when I turned off the pump yesterday the pressure/flow was still very good.
I’m just trying to use logic and if they supply the combi boiler with cold mains tap in kitchen and then tapped into that supply and joined it to the bathroom supply that would hopefully resolve this.
