I have a had a full new central heating system installed in my terraced house, including a new supply direct from the mains. The supply comes in via a 22mm plastic pipe and is connected via the stopcock then to standard copper through to the combi boiler a Glow worm 30si, from here it feeds the bathroom and then to the kitchen, the supply of water/hot water is fine up there but in the kithen its crap!!! is it likely to be down to the taps used in the kitchen, as I am concerned that the slow flow through them could cause damage to the boiler.[/i][/b]
