3 Ways to Fix a Pinhole Leak in a Pipe
A Quick Guide for Sacramento Homeowners
If you see a small wet spot on your wall, floor, or ceiling, at first, you might think it’s a minor spill or splash.
But if you notice there’s water dripping, you probably have a pinhole leak in one of your pipes!
A pinhole leak may sound alarming. But with the right tools and guidance, you can fix it yourself without calling a plumber right away.
What's a Pinhole Leak?
A pinhole leak is exactly what it sounds like—a tiny, pin-sized hole in a pipe.
These leaks are common in older homes or homes with copper pipes.
They can appear for a few reasons:
Corrosion: Pipes naturally wear down over time. This is especially true if they encounter certain minerals and chemicals in the water. Although it’s treated, Sacramento water can still contain minerals that contribute to corrosion.
Water Pressure: High water pressure can wear down pipes faster, leading to these little leaks.
Age of the Pipes: If your plumbing is a few decades old, it’s more likely to develop leaks.
Pinhole leaks are small, so they don’t cause major flooding.
But left untreated, they can cause water damage, mold, and higher water bills.
When to Call a Plumber
If the leak persists or if you’re dealing with multiple leaks, it might be time to call a professional plumber.
DIY fixes are helpful for small, isolated leaks, but they’re not always a permanent solution.
A plumber can assess if you need a more extensive repair or even a pipe replacement.
Tips to Prevent Future Pipe Leaks in Sacramento
Install a Water Softener: If your water is hard, a water softener can lower the minerals that cause corrosion.
Lower Water Pressure: High water pressure can speed up wear on pipes. Ask a plumber to check if yours is too high.
Regular Inspections: Every few years, have a plumber inspect your pipes, especially if your home is older.
Pinhole leaks are a common issue.
But fixing them doesn’t need to be a hassle.
With the right tools, a little patience, and some know-how, you can handle these small repairs yourself.
Remember, taking care of minor leaks can save you from bigger plumbing headaches and water damage down the road.

Before You Begin Fixing a Pinhole Leak
When working with pipes and water, safety and caution are key:
- Turn Off the Water Supply: Before touching the pipe, find the shut-off valve to stop water flow. Shutting off the water prevents a bigger mess.
- Have a Bucket and Towel Ready: Even with the water off, there might be residual water in the pipes. A bucket under the leak will catch any drips and keep the area clean.
What You’ll Need to Fix a Pinhole Leak
For a basic fix, you’ll need:
- Sandpaper
- Pipe repair clamp or rubber patch kit
- Epoxy putty or plumber’s tape
- Wrench (optional)
You can find these materials at most hardware stores in Sacramento County, and they’re generally affordable.
3 Ways to Fix a Pinhole Leak: Step-by-Step Guide
No matter which repair option you choose, start by drying and cleaning the pipe
After you’ve turned off the water and set up your bucket, use a towel to dry the pipe around the leak.
Then, gently scrub the area around the hole with sandpaper.
This will remove any dirt or corrosion and make it easier for your patch or epoxy to stick.
Option 1: Apply Epoxy Putty
Epoxy putty is a fast and easy way to seal small leaks.
Here’s how to use it:
• Break off a small piece of putty and knead it with your fingers until it’s well mixed and a consistent color.
• Press the putty over the hole and spread it out, making sure it covers about an inch around the leak.
• Smooth it down with your fingers, pressing firmly so it adheres well.
• Let it cure according to the instructions (usually 10-15 minutes).Option 2: Wrap the Pipe with Plumber’s Tape
Plumber’s tape can also work well, especially for small pinhole leaks.
Wrap the tape tightly around the pipe, covering the hole and extending a few inches on either side.
This is a temporary fix, but it can help slow or stop the leak until you can replace the pipe section.Option 3: Use a Pipe Repair Clamp or Rubber Patch Kit
For a stronger fix, especially if the leak is a bit larger, consider using a pipe repair clamp or a rubber patch kit.
These kits include a clamp and a piece of rubber:
• Place the rubber patch over the leak.
• Position the clamp over the patch and tighten it down with a wrench.
• Make sure it’s tight enough to prevent water from escaping.Check Your Work
Once you’re satisfied with your repair, turn the water back on. If there’s still water dripping, you might need to tighten the clamp a bit more or add more plumber’s tape.
