What Happens If You Ignore a Pinhole Leak
It starts as a faint mist on a copper elbow. Most homeowners wipe it away and move on. Here is what that tiny hole does next, and why catching it early saves your walls, floors, and weekend.
A small leak never stays small. Call before a pinhole becomes a flood.
Call (562) 245-5416What a proper pinhole repair looks like
There is no patch, epoxy, or clamp that counts as a real repair. The damaged section comes out.
We shut the water off, drain the line, and cut out the corroded section, not just the hole, but the thinned pipe around it. Then we solder in new copper, pressure-test the joint, and patch the opening back. One pinhole usually means siblings, so we check the surrounding runs for the same green crust and thin spots. When a whole stretch is pitted, we say so plainly and talk through repiping that run instead of chasing leaks one by one.
High water pressure caused or accelerated your leak? Installing a water pressure regulator protects the new repair and every other joint in the house. That is the difference between fixing the leak and fixing the reason.

Pinhole leak questions, answered
What Lakewood homeowners ask us about small copper leaks.
Can a pinhole leak fix itself?
No. Mineral crust can slow a pinhole for a while, but line pressure flakes that crust off and the hole keeps growing. The only real fix is cutting out the damaged section of pipe.
How do I tell a pinhole leak from condensation on the pipe?
Look for a green or white crust on the copper right above the damp spot, condensation doesn’t leave crust. If you see a fine mist or feel the pipe itself is wet in one exact spot, that’s a leak, not sweat.
Will high water pressure make a pinhole worse?
Yes. Higher pressure pushes more water through the hole and stresses the thinned metal around it. If your pressure runs high, a regulator protects the new repair too.
If I see one pinhole, will more appear?
Often, yes. Pinholes come from corrosion along the inside of the pipe, so the same conditions exist a few feet away. We check the surrounding runs whenever we repair one.
What should I do right now if water is spraying?
Close the nearest shut-off valve to that line, under the sink or at the fixture, and call us at (562) 245-5416. If you can’t find a local valve, shut off the main.
