Ordered and installed this 55 series pump.I chose this pump because of the "new improved robust pressure switch". Problem is that when I turn water on I get immediate water but it takes 3 to 5 seconds for the pump to turn on.when I turn water off it takes 3 to 5 seconds for the pump to turn off.Unfortunately the pressure switch is sealed so I cannot make the adjustment. Not sure if I am going to live with this or order a 54 series with an adjustable pressure switch.'.
