Hi,
I have just replaced the valve and microswitch for the single water tap in my camper. The initial problem was on opening the tap the water pump would not operate. Now when connecting the two electrical cables the pump will not turn off when turning off the tap.
Is it a case of adjusting the microswitch leaver?
Regards
Graham

Yes normally, or if the switch had three terminals you have connected to the wrong two.

Hi sorted........
The microswitch is a normally open switch (powered circuit), two terminal.
It necessitated the plunger within the valve to hold down the lever of the microswitch while the tap is closed.
An adjustment (with the help of a multimeter ) of the valve body adjuster which permantly tilts the valve body and plunger closer to the microswitch lever with the tap in the closed position was required.
As you open the tap ( unscrew) you can just hear the microswitch release and power the pump.
