A pinhole leak in a copper pipe can be a frustrating and concerning issue for any homeowner. Not only does it waste water, but it can also cause significant damage if left unchecked. The good news is that fixing a pinhole leak in a copper pipe is a relatively simple DIY task that can be done with just a few tools and materials.
To fix a pinhole leak in a copper pipe, the first step is to turn off the water supply to the affected area. Next, locate the leak and dry the area around it. If the leak is small, a simple solution is to apply plumbing tape, also known as “pipe dope,” around the leak. This will create a water-tight seal and prevent further water from escaping.
If the leak is more significant or the pipe is otherwise damaged, you may need to replace the section of the pipe that is affected. To do this, you will need to cut out the damaged section of the pipe and replace it with a new section of copper pipe. Be sure to use fittings and a coupling to securely connect the new section of pipe to the existing pipes. This will ensure that the repair is strong and reliable. It’s important to tighten the fittings securely but not over tighten, as this can cause more damage to the pipes. With these steps, you can effectively fix a pinhole leak in a copper pipe and prevent further water damage.
