Pinhole leak in copper water pipe

[C ountry]

Anybody got advise on how to fix a pinhole leak? One of my water pipes has a slow drip.

Here in south Ga on a commercial building we had the same problem. The first time we called the plumber and replaced the pipe. In a month it's spraying pinholes again. That's when we broke out automotive water hose clamps and cut pieces of inner tube to cover the pinhole then tighten the clamp. We had the city water tested by a national company and the results were so bad the owner of the company called to warn not to drink the water, especially young kids. Trihalomethanes were in the water. City would do nothing but argue the water was fine. Finally a closed manufacturer was designated as a Superfund site and the city wells were replaced.

Just use a good tinning solder and clean both pipe before install

If you can afford it get it all done .

Pinholes in copper will drive you nutz once it starts

If it’s a 1/2 copper pipe and out in the open shut the water off clean the outside of the pipe with sandpaper.
cut a small section of 1/2 pipe and split it in the middle, clean with sandpaper. Add flux to both and install the cut piece over the leak and solder it Into place. Maybe 5 bucks, will last for years and years.
flux on the inside of the pipe gathered there and it corroded the pipe. If second one or third pops out time to replace pipes.
if you want buy a 1/2 inch copper coupler cut the pipe at the leak and resolde.

If it's already showing signs of pinholes the other ones are going to start on that particular piece of pipe it won't be that long. I would replace is largest section of pipe as you feel comfortable with. Just make sure you use a pipe cutter look good get a good clean cut on it and then follow the procedure and the previous post you'll be good to go.

For every one you see, there are probably three that you don't see!
Once you start getting them they start to multiply!
The problem will not cure itself. You could buy some time with shark bites, but replacement is inevitable.

Is it at the joint/fitting/coupler?

Sorry if you said and I missed it.

Think about if it is a convenient place to put in a shut off valve, like if it is the upstairs feed line. might help with repairs in the future downstream without having to shut off whole house
