Fresh water tank leaks

Does the tank leak until empty or just part of the way and stop? This will determine at what level the leak is at then you can troble shoot from there. Mine had a screw through the front storage wall and into the water tank about 1/3 way up the side.

I HAVE A 2010 BIG COUNTRY AND HAVE A LEAK IN THE TANK. I CAN PUT WATER IN THE TANK AND IT LEAKS. I CAN HOOK UP TO CITY WATER AND EVERY THING WORKS OK. HAS ANYONE HAD THIS KIND OF PROBLEM?

2012 Big Horn 5th. wheel--My fresh water tank did the same thing. Look at the filler hose/line hose going to the fresh water tank. My hose was too long and was caused it to kink up and cause the linking. The second problem was the plastic elbow joint to the hose was cracked. Fixed those and no more leaks.

Please turn off the caps, it's considered yelling/rude.

Mine had a large tear in the bottom seam, I found the only guy around that said he could plastic weld the tank, he did and has been good for a year and it is a 112 gallon tank I did add some addition supports on the bottom for longevity\
