KeymasterIn this video, I started off demoing how to test an RVs true holding tank capacities using my Rainwave digital water meter.
However, during the tests, I became aware of 2 small cracks in the top corner of both the shower gray and black tank! When the tanks were filled to max capacity, the 2 small leaks became readily apparent.
I guess I’ll have to put my tests on hold and tend to the cracked tanks first. Any advice on how to best fix them is appreciated.

They are ABS. I got an idea from a guy about cutting up an ABS pipe, heating in an oven, flattening and forming it over the crack and then using ABS glue to seal it up. Seems like a good bet for a cheap fix. 🙂 Will see how pliable ABS is once heated, he said he did a similar corner repair no problem.First I’m going to check out the local boatyard parts store and see what cool stuff they have. 😉
Cheers, Ray

ParticipantNasty spot to get at. Are you planning on dropping the tanks for the repair? Eternabond may be an option.

Thanks, I came across that one too, and a few commenters on YouTube have recommended it.July 26, 2018 at 11:02 am #52667Walt & Vicky Davis
ParticipantI also have a small leak in my black tank. I got under there and found that it is an old repair that is leaking. Looks like they used the ABS repair kit I have seen on line but did not let it set up before using it. Anyway, I could not find anything that would adhere to ABS. A neighbor tried all the “as seen on TV” stuff and none of it would hold. He finally tried gorilla glue and it worked like a charm. Now his was a crack in the line to the dump valve, not a leak in the tank itself. But it worked so I decided to try it. It did work for about two weeks but I noticed the leak is back. Before I give up on it, I am going to re-coat it with the glue again. I think it will eventually hold. So if yours is a crack, I would try that first. :good:
BTW, I have had some experience with MDI (Methylene diphenyl diisocyanate), the active ingredient in gorilla glue. Had to use a release agent with it or it would stick our small press closed. That is how well it bonds to metal…. or anything else.

KeymasterI’ve ordered a couple of the plastic-mend kits. As they look the best for use in the confined area where the cracks are
Will give them a try first. If they don’t work I’ll likely drop the tanks and perform a more robust repair.
July 26, 2018 at 7:22 pm #52681I admire the fact that you’re never afraid to get your hands dirty and tackle pretty much anything! I’ve had a crack in our shower pan for months and JB Weld has been holding up well, not sure if it would work well in your situation.
Good luck!
