This tape is very effective for me to fix the leak in the balcony pipe.Easy five stars and easy to recommend if what you need it for is within a reasonable expectation of what is can handle. I wouldn't use it in a high pressure situation if a leak would be catastrophic or cause damage.
This thing is amazing. So basically, the pipe under the bathroom sink just broke clean off. It’s as if someone took the metal pipe and just cut it straight through. The only way to fix would be to replace or weld. Along with the JB Weld putty, I used this. First the putty and once that was dry, this just in case. I will never have to make this repair again! It’s been a month now and got and cold water has been ran numerous times and not a drop!
On a Sunday morning I discovered a very large hole in the u pipe under my kitchen sink. A friend gave me a roll of this tape and I was amazed at how well it worked.....in fact as a couple of smaller holes appeared I used most of the roll and not one leak.
