A friend just arrived today to our park, in a 1998, gulf stream seahawk, he just purchased as a used trailer. I was helping him set up and we hooked water to inlet line, and no water goes to the trailer. The hose has a air line connection and the lines going straight past the connection travel to bath room sinks, but no water or only a trickle. Is there a backflow preventor immediatly after the water inlet? we thought frozen lines and have a space heater inside the storage compartment for possible frozen lines. any suggestions?
