It works great on a L shape elbow pvc joint in my sprinkler box (about 80psi).
There is a very small leak in my sprinkler box, found last fall and confirmed this spring when turn back on the water (photo 2), there a few hair size water shoots out from it. I removed the component and brings to Home Depot, but they said the manufacture is no longer making it (or out of business), and they do not have any replacement in similar size.
So for me, try some alternative solution is the only way to do before spend hundreds to hire professional. I decide to give this a try to this patty before really hire someone to do it, and thanks to many other reviews in this post, even a lot of people says it doesn’t work with pressured pipe, I did see there are people successfully make it works.
Based on all other people’s experience, I did the following steps with extra caution:
1. clean up all the dirt and debris, wipe out clean with paper towel.
2. rough the surface a little bit with a wood sandpaper (barely add some scratch on the surface, to improve the bond between this patty and the pipe).
3. discards the first1 inch of patty on the edge (some people recommend so), then take a about 1 inch of patty for first application. knead it to bar/snake shape and fold it, repeat for dozens of times.
4. after it fully mixed and soft like peanut butter, make it like bar/snake, wrap it around the leaked position (like a ring over your finger), push it to the surface and smooth the edge (like a band aid around
the ring over your finger).
5. wait 1 hour to 2 hour for first application to harden a bit (the first application only becomes slightly harden after an hour), then do the 2nd application same way to “patch” the 1st application (use 1st application to seal the leak, 2nd application to seal any potential leak of 1st application).
6. wait 3 days instead of just 1 day to let it fully cured (assume there are moisture in the pipe and it take longer to dry)
So far it works well after turning water back on and no more leanings.
I will keep monitoring my pipe, in case if it leaked again, I will update here.
note1: the product i received says its strength is 4370 psi (picture 1), which is much higher than the label in old picture and another product in home depot. I guess that extra strength may also helps if the product is fully cured.
note 2: if your hole is larger, you may need more putty to add extra strength than how much i uses. but i still recommend multiple applications than use everything in one shot.

update: June 12
patched another garden hose with 2 steps. it works for a week but leaks soon after a few usage, i guess flexible pipe may need more skill & patient.

The J-B Weld WaterWeld Epoxy Putty Stick is extremely high quality. It sets quickly and provides a strong, durable bond that works well for repairing water-related issues. It’s easy to apply and has held up well over time. I highly recommend this product for anyone needing a reliable epoxy putty.

Does not when high pressure, probably works in low pressure but not work with my sprinkler broken pipe

Completely worthless. It’s way too soft. It doesn’t cure in 25m at all. It is a one stage epoxy, so when kneading it, it just got softer and softer. Then when applied to the pipe it just fell off because it was too soft.
2 hours later, it is still soft, but water is dripping everywhere. I turned off the water, but it still has slight drips, but they all just build up behind it and it falls off. Thus stuff is completely worthless. I’m hoping Amazon will give me my money back. I used the whole tude on a tiny tiny leak, hoping that if I just keep stacking it up, it will work, yeah, no. I’m afraid to turn my water back on. It’s been 2 hours and it’s still soft. I’ll wait till tomorrow, but honestly, I think it’s going to be worse. And fyi, it was a pinhole leak.
I’ve now purchased some silicone tape, which i will try to put over this small leak… ugh.

Didn’t work for me

I initially read about the use of this product under water or in wet conditions. I looked for the best price to buy some for evaluation, this led me to Amazon.com, which happens frequently (as an aside, i have done over five hundred transactions over the last five years between here and the big auction site – increasingly, the better deals appear here.)
The reviews here cover a wide range of uses, and the review distribution displays polarization between great and abysmal. So, when I was told of a bad leak from the sediment drain valve of my water heater by a utilities worker relighting my pilot after a meter change, I could see a thousand dollar bill flying out the window just as I had the place for sale. (I will disclose this and discount the selling price so the new owner can replace it – I’m just a little short since I’m moving out of this fixer-upper.)
Anyway, I followed the instructions and held my breath. The claimed cure time is remarkably short, so I waited a little over an hour and refilled the system slowly, then turned on the gas. Bone dry, It has been 48 hours under pressure and as hot as the water. I just went outside and checked it, looks good.
I was careful to grind notches in the featureless metal pipe the leaking plastic valve was attached to, so the material had something to grab. i can imagine that surface prep as well as the surface material itself can lead to failure of the repair. Polypropylene, nylon, teflon, poorly prepared PVC – I suppose that these might be difficult for the WaterWeld to seal.
Further success with this material would rate 5 stars, but i will give it 4 now for clear instructions, ease of use, and, at least in this case, a successful repair.

I love JB Weld products, but this putty did not work on a pressurized pvc pipe with a tiny pin hole drip. I sanded, wire brushed, cleaned and dried, mixed putty wrapped it on pipe smoothed down edges and it started making bubbles under the putty. I knew it was not going to work then, i kept soothing it out trying to clog the pin hole, i let it sit for an hour checked and it is still dipping. Gotta get some pvc parts and get to work. IM sure it works for some applications, not with active drip
I gave it an hour and checked back it was not leaking, two days later still not leaking. JB weld is good stuff.
