Maybe a daft question but here goes ..... need to buy a booster pump so my 4040 works as it should.

Pressure at my tap is 40psi if I buy a 60psi pump will I be now getting 100psi or will it just lift it to the 60psi of the pump ??

Just 60psi  i imagine

[Craig Trevain]

would not be strong enough.

Our 100psi booster pumps only work on RO's upto 500GPD's.

Its nothing to do with 'strength' of a pump. 100 PSI is what he needs. Its down to waterflow of the pump.
Indeed your model for upto 500 GPD membranes is a small low flow pump,albeit with high pressure.
 Your other model (Part No: 25110056) looks the bizz, but only has a low pressure? 45 (ish) PSI i make it?
