In this video, I locate and repair a major leak on my RV freshwater tank gravity feed line. I had drained the tank for the winter and was refilling it to sanitize it. As I began to fill the tank, suddenly water started to pour out under the rig!

I got underneath for a look inside the underbelly area and found the problem was caused by several holes in the 1 1/4 inch plastic fill hose. It looks like rodents possibly caused them.
