a 30psi pump will give a faster flow rate but may show up any weak joints or components. basically though you will go through a tank of water quicker. because the pump has an integral pressure switch, it just needs adjusting down a bit

how does one do that?

there is an adjuster screw on the end of the pump...pressure switch end.

it alters the point the pump switches off....it DOES NOT alter the pressure

the pressure is defined by the pumps mechanical characteristics and is none adjustable.

the screw is there to finely adjust the auto switch-off point so the pump doesnt keep running intermittently when the tap is closed.

again, it DOES NOT alter the pressure, when the pump is running it produces 30psi (or whatever psi the pump is rated at)
