flex tape on leaking water tank

has anyone tried this stuff? i have a 2007 attitude fsakg 33, it is a real piece of **** but i keep it going. i have 2 water tanks, i think aztec brand, they are black, both have leaks in them as does the black water tank but that crack is up top so i just drain it more often. i tried plastic welding the cracks on the water tanks but my dad sent me this link for flex tape, kind of looks like a scam but then i found a youtube video where a legitimate tester guy seems to make it work.

anyway, not worth it for buy new tanks, was wondering if anyone had used this stuff. i was also starting to think about using this super sticky roof repair tape i have, it was expensive, i think it is edpm tape, maybe it is the same stuff. eternabond is what is it called, it looks like same stuff. any thoughts appreciated, unless you make fun of me,,,,,,which may cause me to cry so choose wisely.

Black? Are they MDPE or ABS? If they're ABS, like a Valterra brand tank, you can patch them permanently using a homemade concoction. You buy ABS pellets online (Ebay) and dissolve them into a paste the consistency of peanut butter with MEK. Then spread it on while it's still nice and sticky. Strong stuff.

If they're MDPE then flex tape may work for awhile, but plastic welding is the only permanent fix.


To make it stronger, acquire some of the pvc type screen for screen replacement on doors and windows and cut a patch a lot bigger than your crack or hole in your tank. If its a crack, drill a small hole at each end of the crack to stop the damage from spreading. Then smear the above paste over the wire patch and a little beyond, let it set 24 hours and do it all over again with a bigger piece of plastic screen and let it set for 24 hours. I do this 3 times actually. I have used this method on several tanks over the years and the patch is stronger than then tank. After patching, I have never had it leak in that spot or around it again.

I don't know if it would work on the tanks, but our sky-light in the bathroom had a crack and a small leak after hitting a low tree branch. Put a strip of Flex Tape on it and it fixed the problem. Its been on now for a year, still no leak. Good Luck and Happy Camping !!!

Too many geezers, self appointed moderators, experts, and disappearing posts for me. Enjoy. How many times can the same thing be rehashed over and over?

Buy a roll of the stuff. If it works, it works. If not, you're no worse off.

Let us know !
