In 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.

Nasty spot to get at. Are you planning on dropping the tanks for the repair? Eternabond may be an option.July 26, 2018 at 8:07 am #52659

Thanks, I came across that one too, and a few commenters on YouTube have recommended it.July 26, 2018 at 11:02 am #52667
I 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.
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.

I’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 #52681
I 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.
