How to Repair a Pinhole Leak in Copper Pipe

If you have a leaky copper pipe, you’re not alone. Pinhole leaks happen frequently with copper pipes, and fortunately, they’re relatively easy to fix. Here is a step-by-step guide to repairing pinhole leaks in copper pipes.

Step 1: Turn off the Water

The first, and most important step is to shut off the water supply to the leaky pipe. You can do this by closing the main water valve, which is typically located near the water meter.

Step 2: Drain Water

Once you have turned off the water supply, drain all the water from the affected pipe. You can do this by opening a nearby faucet.

Step 3: Clean the Area Around the Leak

Using sandpaper or a wire brush, clean the area around the leak to ensure that there is no dirt or debris that could compromise the repair.

Step 4: Apply Epoxy Putty

Apply epoxy putty to the area around the leak. Epoxy putty is a two-part adhesive that will bond with the copper surface and create a seal around the leak.

Step 5: Allow Epoxy Putty to Dry

Allow the epoxy putty to dry completely. This can take anywhere from a few hours to overnight, depending on the brand and type of putty.

Step 6: Check for Leaks

Once the epoxy putty has dried, turn the water back on and check for leaks. If the repair was successful, there should be no water coming from the previously leaky area.

Step 7: Monitor the Area

Even if the repair seems successful, it’s important to monitor the area over the next few days and weeks to ensure that there are no further leaks or issues.

Conclusion

Repairing a pinhole leak in copper pipe is a relatively simple process that can be done with just a few tools and some epoxy putty. While an occasional pinhole leak is common with copper pipes, consistent or frequent leaks might indicate a larger problem – in which case, it’s best to consult a professional plumber.
