hi there, just put a new kitchen in and my hot water pressure is no good, it comes out like a dribble and takes about 5mins to fill the sink to wash pots. its a gravity fed system, im guessing its to do with the tap, its a pull out mixer shower head tap so it has more flex hose to go round. The last taps was single standard taps. the baths got the best pressure. Is there any way i can increase the pressure... water pump etc ???
