Water Tank Leak (my fault)

[Marsland]

Well this is embarrassing 😮 :M ! But I need some advice on water tank repair.

This is my story. In my exuberance to make my TT more cold weather protected I dropped the underbelly (coroplast) and after checking out the tanks, connections, duct work, and everything else I proceeded to put in a layer of Reflectix. Not much more insulation but more than it had to start with.

Now the fresh water tank rests on the passenger side frame rail and extends to close to the other side. Well on the passenger side the manufacturer used short screws to attach the coroplast to the frame below the tank. I knew that :R cause I took it apart!!! But in my haste to put everything back together I forgot and used a long screw. (expletive deleted)(expletive deleted)(expletive deleted)!!!!!!

My question is (finally) can this hole in my tank be repaired with a reasonable chance of success or should I swallow hard and purchase a new tank? If it were exposed I would more than likely try to repair but being covered I don't want to unbutton everything more often than I have to.

Thanks,
Richard

I have repaired many plastic tanks with a soldering iron and a gallon milk jug. Just cut the milk jug up in to a 2"square and with a wide soldering iron just keep going over the pathches and keep adding them on there till you build up the area.

I would use West Systems "G" flex epoxy.
Any West Marine store carries it.

Don't use any old epoxy. Many of them are not compatable with poly material

Call West Systems up and they will advise you.

I've seen tank repairs being done with a small piece of a gallon water jug (the flexible kind of frosted jug) with a liberal amount of superglue - and well, you get the idea. I'd go over the area with several layers of patches, each one getting a bit larger than the last.

If it works, great news! If not, then maybe a new tank?
