Went to the van today to have a sort out the pipes had frozen so i disconected the pump but forgot to turn the tank valve of, had a knock on the door looked at the van and i see lots of water on the floor. well opened the door then relised what i done the pipe had defrosted and chucked out 500 litres of water in the back of the van. quite funny when i opened the door it poured out over my feet. Just what i wanted on a sunday morning lol
