Help! Temporary repair to grey water tank.

J-B Water Weld

IMHO a miracle! You can patch 'underwater' with this stuff.

I had a shock bracket break and it punched a hole in the side of the gray tank. I used Eternabond to seal it 5 years ago and it's lasted.

Stress from the location is a good point. I think I would get a piece of relatively thin (~.060) aluminum or steel to help support the area. The ones I've seen are sitting on foam insulation so there is some flex anyway, just something to hold the edges of the split flat so they don't bend down and stress the Eternabond.

Eternabond is the first thing that came to my mind for a temp repair.. If you get it clean it will stick...
The problem is.

You will have problems getting it off :R when you attempt a more permanent repair.

so it will fix it for now but you will be shooting yourself in the foot.

I would use plumbers epoxy. It comes as a small round putty like stick. You cut off what you want to use. Then, you work it with your fingers till it is a uniform color. Put that into the crack with overlap. It will harden and may be a permanent repair. I have repaired buckets, plastic fenders, potty water tanks, plastic rings that the toilet hold down bolts fasten too and lots of stuff. I have never had a problem with it once it hardens. You can buy it at home depot and lowes. For your appilication it is better than eternabond.

Thanks for the quick input. I should have mentioned, I'm stationary until November, so there won't be much pressure on the patch. I'm thinking it'll work just fine. I have my fingers crossed!

Don't Pitch It... PATCH IT!!
Try a 4-foot roll of this amazing product.
Double thick MicroSealant EternaBond® RV-EMT Mini-Rolls are the perfect answer for difficult repairs like pool liners, rubber boots, expensive covers for boats, grills and outdoor furniture, holding tanks like those on wet/dry vacuums, cracks in basement walls, toilet tanks, leaking shower stalls, sinks, etc.! EternaBond® RV-EMT Mini-Rolls are 4' long and 2" wide.

Good luck with it.

Cool, go for it! Let us know how it works.

I'd go to an RV store and see if they have any temp patches...you should be able to find something...

I'm not sure about the eternabond...that's a lot of downward pressure. Whatever you do, drill a small hole on both ends of the crack to stop it from spreading.
