There is usually a small screw accessed though a hole in the pressure switch cover (the blue thing on the pipe end of the assembly). This may be covered with a label. I would comment that if you do not tell us why you want to adjust the pressure we can not give advice that may well cure the problem that could still be there with reduced pressure. Tony Brooks

found the screw. i have 2 pumps working in parallel feeding the cold water just fitted to a sailaway. on pump cuts out much earlier than the other. a quick check revealed there was a 12psi difference between the 2 pumps cut out pressure. hence the need to adjust

Thats fine. The most common thing people seem to want to adjust the pressure for is when the PRV on the hot water starts leaking and that is usually caused by scale on the valve seat, not excess pressure. Tony Brooks
