Hi

I have a fairly standard Gravity-fed vented system in a fairly standard two-storey house. I have just re-done my kitchen and replaced the taps with a funky new monobloc (ceramic valve) mixer.

As a result, the hW pressure through this tap is really low and with the mains pressure feed for the Cold Water, the tap temparature is either freezing cold and very powerful or boiling hot and v slow - there's no "mixing" of hot and cold. I've tried closing the service valve for the CW a little and this works, but it's not great at mixing.
I was thinking of adding a HW pump in the loft from the cylinder, but my mixer shower in the upstairs bathroom already has a pump attached to boost the tank-fed Hot and Cold feeds. I have another shower that is a power shower that also relies on tank-fed low pressure hot and cold feeds.
Access in my new kitchen it very limited, has anyone any suggestions as to how I can boost the pressure for the kitchen tap??
Overall pressure of the hot taps in the bathrooms(s) is not great - but not as important as the kitchen for washing-up etc etc.

Thanks in advance for help and advice
