Today after our caravan had been serviced we decided to clean the pipes tank etc with puriclean, after filling the tank with the rolla ball and filling the hot water tank, we then opened all taps to let the water flow, when we turned the taps off the pump
kept running, the only way to stop it was to turn the switch off, new caravan 2012, we have tried the shaking of the pump but no different, but we did note some water coming from where you push the pump in on the outside of caravan any advise would be grateful.
