While living on a powerboat a few years ago I installed potable water quick disconnect fittings for fear of filling the boat up with water and sinking it. Everytime, we left the boat we would turn the water off and disconnect the water hose. We have the same set up on our sailboat today.
Hate the time it takes to screw both potable and black tank water hoses into the trailer water connections and ensure they are leak tight, sometimes requiring channellock pliers. Solved that with quick connect fittings. Now set-up connections are fast without leaks and shortens the tear-down duration.
Does anyone else use these? Do you any other set-up/tear-down tricks?
