Your 20psi is only 1.4 bar, that will be fine.

Nuts - changed it today, real easy 10 mom job, and it works so old pump must be knackered! Only prob is new one leeps pulsing, while no taps are on! Cant see any leaks etc so dont know what the prob is? Very frustrating to say the least!
Also the extra 7psi does mot seem much of a difference so dont think that is the problem!

Hi Simo The extra pressure will just give you a power shower effect if you open fully the tap on shower.To stop the pump from pulsing you need to fit a expansion vessel,this is a container that has a rubber divider in the centra and is pressurized on one side, the pump fills the space against the pressure so that when pump cuts of there is still pressure maintained against the on/off pressure switch that controls the pump,this stops the pump from switching on straight away,the other advantage of having one is that of checking if you have a minute leak on your water system,if you switch of the pump and leave it under pressure of the vessel then switch it back on after a long period if pump does not immediately switch back on ie has maintained the pressure in the system you have no leak,if it does come on immediately you have a leak maybe only a weeping but leaks don't repair themselves.There are several sizes, bigger the better,they should also be fitted vertically ie downwards if possible but if not just as far down as possible if space is at a premion.One other thing if your hoses are connected/pushed on smooth pipe fitting two hose clips on each joint will prevent the extra pressure of your new pump from blowing the hose off the pipe.John

If the cut in and Max pressure of your replacement pump is quite different to existing, don't forget you may need to adjust the pressure in any accumulator accordingly
