I got yelled at by a campground host once for running a hose from an unthreaded outlet to the TM water inlet. He said that they didn't have anti-siphon valves on their outlets and that by putting a hose into our system and having it "connected" to their system that I could contaminate their system. They had actually filed down the water spigot threads so they couldn't be connected to a hose.
