Question:

I have a small cut in a copper pipe that doesn't leak when the faucet is closed, how do I fix it?

I would prefer to solder it rather than putting a rubber band around it.Do you know a website or a video that shows how to do it? I repeat, the cut is not big, but when I open the faucet it starts to leak.

Answer:

There is a product that you can get at the hardware store. It is called Liqua-weld. In comes in two styles, ferrous and non-ferrous. Get the non-ferrous and follow the directions. It will seal a small hole very well.
Here is a web site that shows how to solder copper pipes. Make sure there are no flammable components near the cut and use lead free solder. Lead can leach into the drinking water.

Try Mighty Putty. It's at Target. It's supposed to stop leaks. I love it. I used it to patch a small hole in my garage's siding. That was 4 rainstorms ago and it's still there, solid as a rock!
