Fresh Water Tank Leak Repair Advice

[jim_harvey]

Hello,

Noticed water dripping slowly off the bottom of the frame in the front of our 2014 Southwind, and at the same time noticed that the water level in the 80 gallon fresh water tank (actually I determined there are two 40 gallon fresh water tanks connected together) dropped more than it should have with the little bit of water we were using.

I found a steel plate screwed to the side of the frame, removed it and was able to see the two tanks laying side by side. There is a small hose connected to the bottom of the tanks in effect joining them together.

The tank on the left was actively leaking a small stream of water along a curved line, similar to a seam, about a half inch from where the hose connects to the tank.

The hose is definitely NOT loose, and when I put a slight pressure on the hose I can see the leak increase along that curved seam. I'm afraid to touch it now as it feels as though it would not take much to make it fail completely!

Does anyone have advice on a product that could be used to apply to the seam to stop the leak, and more important strengthen the area so it doesn't occur again. I think the pressure of 40 gallons of water must have made a defect occur in that area!

TIA

Jim

I have a picture but can't seem to find how to "attach" it to my post?

Plastic welding is the only reliable repair- either with a soldering iron, or Harbor Freight has an inexpensive plastic welder, basically a soldering iron with a large triangular flat tip, and plastic rods for filler.

There is a plumber's putty that is an epoxy product that works well. I used it a few years ago to repair a 3/16" hole in my fresh water tank. Don't ask me how it got there. Hope this helps.

And yes, the tank is white plastic.

Is there some kind of sealer, like a caulking compound out there?

Thanks, I do have a soldering iron, so that may be an option...

Going to assume that it the tank is white plastic. You could try a soldering gun with a wide tip (tank empty and crack dry) to fuse the crack back together.

Had a similar occurrence in our last trailer. A corner was seeping, and had a small crack. A couple of minutes with the solder gun fixed it. No leak for almost 6yrs before getting new trailer.

Forget what it is called but the plastic looking tape that fuses to itself when wrapped around the pipe should fix it.
