Improper Installation Could Cause Pinhole Leak

Pinhole leaks in copper piping

Imagine a tiny, pinhead-sized hole in one of the copper water pipes running through the walls of your home. Water slowly drips, drips, and drips. It soaks into the insulation and spreads until your wall becomes a breeding ground for mold and mildew that cannot only make you sick, but can also go undetected for months or longer. Over our 25 years in the plumbing industry, we have seen this scenario many times here at the Twin Home Experts.

7 Reasons Why Copper Pinhole Leaks Occur

  1. Water quality issues are the number one culprit.
  2. Thin copper pipe grade, such as type “M.”
  3. Improper installation of copper pipe and fitting connection.
  4. Neglecting to de-bur the inner pipe before inserting into fitting.
  5. Applying too much flux paste and failing to clean it upon completion of soldering joints.
  6. Recirculating a pump that is too large for a water system, which creates too much traveling velocity.
  7. Copper pipe becomes in contact with metals and concrete.

We always recommend hiring a company that understands not just repairing or fixing continuous copper pinhole leaks, but also a plumber who understands water conditioning.

Another great solution to preventing pinhole leaks is by installing PEX piping materials for your water system. PEX pipes are non-corrosive pipes that can handle severe water conditions. In fact, the manufactures provide some long-term warranties and are also backed by an insurance policy.
