Boosting gravity fed taps

[M1957]

Hi,

I have a gravity fed hot water system with a cold water tank in the loft. We recently installed new taps in the bathroom but they are made to work on a modern system with higher pressure and don't have the flow rate I would like. We like the design and quality of these taps so I would like to look at options for boosting the pressure.

What pump system might be suitable for this use?

This should do it... it'll pump your whole house unless you have accessible separate feeds to your taps though https://www.tradingdepot.co.uk/monsoon-standard-3-0-bar-single-shower-pump
