Water Line routing.

Well, as it turned out, the lines were not cracked under the slide out. Thank goodness! That would not be easy to get to. What had happened was the plastic threaded fitting to the sink hose cracked and broke off. Essentially the water was just flowing stright out the hose and over the floor. Simple fix with a new hose from the hardware store. As I was fixing it I noticed that I had already fixed the other hose to the sink. I turned on the water and it didn't see any flowing water. But I did hear a steady "PSSSSSSS" from the other side of the camper. One of the PEX line elbows had cracked that leads to the outdoor shower. There is no direct shut-off for that line so I had to fix it. Picked up a new Watts push-to-connect elbow and fixed that leak. No more water leaks. Next thing to fix would be the water heater tank. I'm pretty sure that is cracked somewhere.
