At the start of my recent holiday – on the day we arrived in France (after all the checking I had done before we left!) we lost our water supply.
The water flowed fine for a second or so – and then just went to a trickle on both Hot and Cold supplies. After much checking of pumps, pump filter, pipes, connectors etc… I finally found the problem:
There is a Tee-Valve change-over on the inlet of the pump to select between “External water tank” and “Internal Water tank”- on the “pump” side of the Tee-connector there is a “Filter Mesh” INSIDE of the fitting – this was blocked! – To clear this, you just have to remove the Tee-Connector (push fittings) and run the fitting under a “campsite” tap to reverse flush the dirt from the filter. However, you would be advised to drain ALL of your water system down first, including the hot tank and on-board tank as otherwise you will have water “finding it’s own level”.
Once I flushed the valve and refitted it – No more problems!
