Pinhole Leaks – Why They Happen & How to Fix

A Pinhole leak is the most common type of home piping leak. Pinhole leaks occur in all types of home plumbing but pinhole leaks in copper piping are what our Plumbers deal with the most. Typically, these holes are less than 1/8 inch wide and a lot of times lead to more damage than a leaking kitchen sink.

Signs That You Have Pinhole Leaks in Your Home

Below are some signs you should be looking out for to avoid pinhole leaks in your home!

  • Dropping Water Pressure. One thing a pinhole leak can affect immediately is water pressure. If you’ve noticed a drop in pressure, whether in your shower, your faucet, or anywhere else where you use running water, there could be a leak somewhere.
  • Running Water Meter. Another way you can check for a small leak in your home (or any sized leak for that matter) is by checking your water meter. First, make sure that there is no water running in your house from any of your appliances, and then check the meter. If it’s showing signs of water running, then there might be a leak somewhere in your plumbing.
  • Mold and MildewPinhole leaks are notorious for causing mold and mildew growth because they often occur inside the wall where they go undetected, creating the ideal environment for growth.
  • Pipe DiscolorationThe exterior of your copper pipes should always look copper-colored.  If you’re noticing brown, green, or blue discoloration, that’s an indication of trouble.
  • Water Damage. This is the last and worst sign. If you’re seeing water damage either in your walls, floors, or anywhere in your home, it means there’s been a leak that’s run for quite some time. Water damage can cause mold growth and will weaken the structural foundation of your home when not treated quickly.

What Causes a Pinhole Leak in Copper Pipe

Although very small on the outside of the pipe, a pinpoint leak is actually a sign of a much larger corrosion problem inside the pipe and a symptom of long-term corrosiveness. When a copper water pipe corrodes and leaks, or bursts from freezing, you have to fix it fast. Dean’s Plumbers copper pipe pinhole leak repair includes removing and replacing the faulty piping.
