Last month, I inspected a failed plumbing system where three different transition methods were used incorrectly between copper and PEX. The resulting leaks caused thousands in damage, highlighting how specific these connections must be handled. Through years of troubleshooting, I’ve identified patterns in what goes wrong during these critical transitions. Common copper to PEX installation […]

During a emergency repair in a historic building where soldering was prohibited and space was extremely limited, compression fittings saved the project. We completed the copper-to-PEX transition in confined walls without special tools or open flames, demonstrating their unique value in challenging situations. Compression fittings excel in copper-PEX connections by eliminating need for specialized tools

In my twenty years of plumbing experience, I’ve removed copper-PEX connections that were still performing perfectly after 35 years of service, while others failed in under five years. The difference always came down to installation quality, material selection, and water conditions rather than any inherent limitation of the connection method itself. Properly installed copper-PEX connections

I recently inspected a push-fit installation that had been operating flawlessly for 12 years in a commercial building. The system showed no signs of degradation, demonstrating that when properly selected and installed, push-fit fittings provide exceptional long-term reliability for copper-PEX connections. Modern push-fit fittings provide reliable connections for copper-PEX applications when properly installed, with most

During a recent hotel renovation, we had to connect new PEX systems to existing copper plumbing throughout 200 rooms. By creating a standardized tool kit and connection protocol, our team completed the project two weeks ahead of schedule with zero leak incidents. Copper-PEX connections require transition fittings, proper cutting and preparation tools, and connection-specific installation
