Fresh Water tank leak, Montana High Country 338DB

[adkandy]

We have a 2014 High Country 338DB. No problems with the fresh water tank until about 2 weeks ago. For no known reason, it leaked to the 1/3 point. Once it reaches that point, the leak stops. I had to cut away of the under belly cover to let the water drain out. What would start it leaking like that? Since it goes to the 1/3 mark and stops, I'm thinking it might be the contact screw. Does this make sense? Is it possible to get drawings of the tank area/plumbing? I've just winterized it, so this will be my spring project. I'm trying to get as much information as I can on it now.

In advance, thanks for your suggestions.

A leak at the contact screw might indeed be a good starting point to look for the leak --- it does make sense.

Unfortunately, Keystone does not provide any kind of schematics for plumbing, electrical or other construction details.

Your best bet would be to unscrew enough of the coroplast underbelly so that you can have access to the FW tank and check to see if you can isolate the origin of the leak.

My trailer is in the shop this week, replacement of the front gray tank. Crack a bit over 1/2 up along an edge/corner of the tank. Hard to see until the tank was partially full and crack started to spread ... of course, shortly after just a matter of looking "up stream!"
