I have a 2013 Hearland Northtrail 24RBS. The first time I used the black tank flush line it worked perfectly. The second time was after a few months and it didn't put any water in the tank. It seemed as if all the water was going to the underbelly. Does anyone have a schematic of the black tank and where the flush line connects? I started pulling the underbelly and it looks like I may have to cut it to get access and I want a schematic so I know where to cut. The black tank flush line starts on the back of the trailer by the city water connection and goes inside under the shower then forward under the sink and I lose it after that.
