water tank sealer

[JustClean]

I've got a square stainless steel tank that is leaking at the bottom. I got somebody in to weld it but it is impossible as the material is just to thin and there is also a smaller tank within the bigger tank with no access. I tried to seal it with a putty but this only helped a bit. I can't put another tank inside the leaking one as it is part of our recycle system with too many connections, etc. So I thought maybe if there was like a "liquid steel" that I could pour into the tank to cover maybe 1" of the floor that would seal it. Have you ever heard/seen anything like this?
Thanks.

If it is light guage St.St. you will need to have it TIG welded.

You can solder it, but I've even had soldered repairs leak after a number of years.

It was TIG welded before and the trouble is that the crack might be in an area you can't get to it.

Flex Seal is absolute junk. It is almost like spray paint.

I don't know I didn't try to float a pickup.

There is a 2 part epoxy that you can get at Home Depot or Ace Hardware that works pretty well. I use it on a SS tank. It is totally submerged in water constantly. I'll check the name and report back.

Dries in 45 minutes. I put the water back in the tank after that, and they say it cures in 24 hours. I don't know because I put it back in service after 45 minutes. If I put it on properly it lasts for a couple of years.

I sealed a leak in a flat bottom aluminum boat with RTV (similar to silicone) that lasted several years. Might be worth a try. I just dried it out good and ran a steel brush over it before coating it.

Thanks for all the replies. The trouble is that I can't really get to all the corners. So if there was a liquid that I could just pour in that would probably be perfect...

JB Weld makes some good stuff…even cures under water! I just fixed a leaking rinse tank with it. But since you can’t get to the corner…and ff the tank’s contents are circulated constantly, Fix A Leak (www.fixaleak.com) will seal up to 1/8” hole. I’ve had good luck sealing leaky floor heat tubing with the stuff…it’s remarkable! I bought it from a local swimming pool supplier…$30/quart. Might be worth a try.

I've used fix a leak also on leaky floor heat. You can get on Amazon.
