How Do You Repair Leaks In PEX Tubing?

Unlike many piping materials, pex is not prone to leaking. However, you will not miss one or two situations that need your attention. Almost all leaks in a pex connection will occur  at the connection spot (joints) which is mostly as a result of poor workmanship during installation.

The process of repairing pex is as easy as a new installation considering that it happens at the joints.  You first need to identify whether the connection uses crimps or clamps system. Then you will have to get brass fitting with copper or opt for steel crimp rings which is quite cheap and effective way to repair pex tubing.

Pex Installation Tips that Prevent Leaks

  1. Use pressure to test and monitor the pex system soon after installation as guided by the local building and plumbing codes. If you happen to have a leak in the system, the temperature gauge will show a lower reading compared to the initial reading.
  2. If the system uses a crimp connection, ensure you use a Go-No-G0 gauge for the test to get accurate results.
  3. Some leaks happen during and after freezing hence it is important to check the manufacturers guide on freezing protections and follow their freeze prevention and installation guide abiding to all the requirements.
