Wrong pressure in my hot tap

[briandayson]

I have just installed a mixer tap with shower fitting. The model is Greenwich /Hanover Bath Shower Mixer Taps 476409.

The water pressure from the hot tap is pathetic. I contacted the suppliers and they told me the tap requires 5 bar pressure(?) to operaqte properly.

I do not have a combi bolier, the hot water is gravity fed.

Is there anything I can do to increase the water flow? The pressure in the washbasin is fine.

only fit a pump on the gravity hot water supply from the cylinder

I've got a pump which feeds the shower - could I take a spur off that?
