I had two hoses hooked up to my trailer, one fresh water supply and the other to the black water rinse. He turned off the valve that supplies water to two spigots. He turned the spigot to the black water rinse on, the fresh water supply was still open, and left the main valve off. I turned the main vale back on allowing fresh water to the unit. He trespassed on my legally rented space, disconnected my equipment and left it in an altered state. My wife was in the unit and he made no effort to request trespass permission.
As far as this being my fault and the insurance denying the claim, I would compare that idiotic statement to having a car bomb planted in my truck and then saying it was my fault for starting the truck and causing the explosion. Please be realistic in your reply or do not waste the space in this thread.
