Scratched 1/2 copper pipe with drywall saw, no leaks yet. Potential issues?

Went a bit overzealous while sawing my basement bathroom ceiling for a new fan. And didn't notice I completely scratched/nicked up a copper pipe above with my drywall saw.

Those are 1/2 inch pipe, and is used to carry hot water throughout the house. Those pipes are few decades old. My area's water is generally pretty good, haven't had problems so far.

It is currently not leaking at all, but I'm rather hesitant to put in the new fan if the pipe is going to leak in the future.

Just wondering if those scratches are going to cause a problem in the future? I can leave the hole open to observe the pipe for a few more days.


Some photos of my mess up.

It doesn't look to bad, and if it's not leaking at the moment it's good for now.

20 years from now?

If you can solder, clean the nicked area and melt solder over the area. The patch will last as long as the pipe. You will need to drain the water from hot water pipes (at least to a level below the nicked elevation) before soldering.

I was going to make the same suggestion beelzebob made. It will last your lifetime and perhaps the next owner also.

It doesn't look that bad to me, though it is more than just a scratch.

If it were me, I'd probably just forget about it. If the water ever erodes the pipe from the inside, it'll start as a small leak, which will start dripping down the fan hole. I'd probably gamble and never think about it again.

But the solder idea works too. There are also rubber repair clamps, but I'm not sure how well it would work with the coupling directly next to it. Maybe just a small piece of repair rubber with a hose clamp over it would provide enough peace of mind.
