Goodman, thanks @Baldmonkey 

A booster pump needs fitting after the pre-filters and before the first membrane, you may need some extra JG tubing to fit the pump as below.

No it's this https://purefreedom.co.uk/product/24v-aquatec-reverse-osmosis-booster-pump/ you will also need a timer switch as they can't be run continuously, I run mine for 45 minutes on 15 minutes off throughout the day
