J-B Weld WaterWeld is NSF certified and safe for contact with drinking water. Review: Pretty good stuff - underwater - I got this Waterweld to plug some tiny holes in a concrete drinking water cistern. The stuff works great. You need to use it correctly however. My concrete is Spaulding so if the loose gravel is not removed or sealed first, the Waterweld epoxy will incorporate the grit and not stick properly. I've used this stuff on cleaned concrete, PVC, ABS (all under water) and rubber (at the waterline) and it has held more than a year. I used it originally in summer 2023 and didn't use it all. I wrapped the remaining unmixed epoxy in plastic, used the remainder in the summer of 2024 (worked fine). Then bought another 2 pack in the summer of 24. I have more repairs to complete in summer 2025 and have one tube left. I'm sure it'll work fine when I get to the job this coming summer. If I need more, I will definitely buy this type/brand as it's served me well. Review: So easy to use! - This was so easy to use and worked really well! I am not even close to being a plumber, but this sealed my leak up. Used on old copper pipe in my basement. Drying/curing time was fast and the leak stopped almost immediately. There was enough to seal around my pipe with some left over. Not sure it would be enough to do 2 full fixes but a good amount. ## Features - J-B WELD WATERWELD: A hand mixable two part epoxy putty stick, that can cure under water and is ideal for repairing plumbing, fuel tanks, tubs and showers, drains, pool and spa, boats & potable water tanks and more!

There was enough to seal around my pipe with some left over.

I have recently used JB weld waterweld for my leaking fuel tank earlier and I like so much that I am buying this product again and also just spent quite a bit of money and ordered a range of other JB weld products. Hope these items remains soft and pliable for long storage. Buy the 2-pack to save money.
