After more than 30 years, this is a first for me. Basically without warning water simply pours back out of my fresh water inlet. I have drained the fresh water tank and tried again but water still spews out of the inlet and no water reaches the storage tank.The van is still under warranty so I have booked it in……. but a month away. I would be very grateful if someone suggested an easy solution which would let me get on the road again sooner. Thanks in anticipation.
