Water pressure with new kitchen mixer tap.

Hi,

I've just fitted a new mixer tap in our kitchen which used to have good pressure to the hot supply (mains fed cold), but since fitting this tap the hot water pressure has become much less. Its plumbed in copper 155 pipe to below the sink then there is a 15mm flexi pipe which fits onto the (I think) 8mm copper pipe that comes with the fitting, I'm guessing that the reason for this is that the reduction in size of the pipe after the flexi is causing the flow to be reduced (the kitchen is the furthest room away from the boiler).

Has anyone got any tips to resolve this, I was thinking of fitting a pump in the loft to boost the flow, but have some issues with how that would be switched from the kitchen.

Thanks in advance,

Kev

make sure the tap is not designed for a high pressure supply...many are.

Common problem due to most modern taps being designed for high pressures, as ollski mentioned. Pump on hot supply is an option - operation would be automatic due to flow switch on pump. However plumbing of pump can be complicated due to need to avoid drawing in air. Best to find taps suitable for low pressures.

Thanks for the responses.

I think I'll try to pump the hot supply. Either fitting the pump in the loft or in the kitchen cupboard below the sink.
