We bought a new Lunar this year which gives us the option to buy an outside hose (to clean muddy booys,hose dogs down) which connects to the side of our water inlet. Has anyone got one of these hoses, as we were under the impression you plug it in to the special inlet and press the trigger on hose and hey presto water should come out from your inboard tank. Guess what ours doesn't... have we got a dud hose or are we doing something wrong.
