If the pump was functioning okay previously and the pressure switch hasn't been altered then a low voltage leisure battery will cause the water pump to run continuously as it doesn't support enough power to stabilise the current. The advice is to get a voltmeter and physically test to see how much power is in the battery. If connected to a mains hook up supply and the battery is proved to be low then you need to test the onboard charger to make sure that a current is being distributed to the battery.

Sometimes an airlock will fool the pump into thinking there is no water coming through. I've had this happen to me on a couple of occasions.
I turn the pump off at the main switch, disconnect the pump and remove it from the water container, shake it a little then put it back together and turn on the power, this generally cures it.
You might also want to open all the taps for a short while to release any air.

Hope that helps.

Does your van have micro switches on the taps?

If there are micro switches you will see wires under the taps. (Faulty micro switches have been known to cause this problem). If there's no micro switches you will have a pressure switch turn it round (clockwise I think to turn it down) see if that works. There is a previous thread on this topic here
To rule out the pump next time you're away in the van ask a neighbour if they'll let you borrow their their pump, if the problem is replicated with their pump the problem is in the van.
