This is my first one. On a similar subject.
When I'm finished and I want to reel in 100 metres of hose full of water:
I have a hoselock multi connector in the van. I go back to the van, switch off the pump, I have a hose connected from the multi connector to the air vent in the top of the tank, open the valve on that connector, leave the connector to my hose open, reel it in. As it reels in the water in the hose runs back into the tank nice and quick.
