    Try installing a check valve after your pump's discharge line. This is to prevent the pump's frequent on/off and protect its seal life.

    The check valve at the pump's discharge line is a MUST HAVE thing.

    You only need 13 psi for water to start flowing at 30 feet height.

    Our pressure switch is set to cut-out at 25 psi, cut-in at 15 psi. We don't have problem at 2nd floor shower.

    There must be air inside the tank when started new. It is this air that gets compressed and develop the pressure when the pump starts.

    Water is incompressible so if you don't have air inside the tank, the pressure switch will immediately cut-in (starts the pump) as soon as water flows out, and cut-out as soon as flow stops.

Just watch out for leaks and you'll know where the culprit is.
    i use blue plastic pipe before the pump. but after pump, everything is metal.
