I have a male threaded adapter for steel pipe on a 3/4" copper pipe. When twisting an extension steel pipe on the fitting, I applied a bit too much force and that slightly bent and creased the copper pipe, which I mostly reverted with channel locks.

I tested it and there was no leaks but the crease is still visible if you look hard. I was wondering if this compromises the pipe to be more succeptible to leaking in the future.

  • There is no dripping right now and my question is about the probability of it happening in the future

copper is fairly soft stuff and a single crease-uncrease operation won't cause a leak by itself. but that piece is now weaker than the rest of the pipe so it may be the first part to fail is the system is over-stressed.

  • Agree. Copper is generally rated for 20-50 years. Creases will be reflected in the smoothness of the inside wall of the pipe and cause additional turbulence which will cause that inner wall to wear away. Sep 13, 2020 at 0:57
