When I managed a 50-unit apartment retrofit, we initially planned to use copper piping throughout. However, after conducting a detailed cost analysis, switching to PEX saved the project over $35,000 in installation costs while completing the plumbing phase three weeks ahead of schedule. This experience makes clear the question: PEX vs Copper Which Saves More on

During a multi-family building project, we discovered several PEX-A pipes had developed stress cracks just behind crimp fittings after only two years of service. The investigation revealed that improper crimping techniques had compromised the pipe integrity, leading to costly repairs and tenant relocation. Yes, crimp fittings can damage PEX-A pipes when improper tools or excessive

During a large apartment complex installation, we discovered that using standard crimp fittings with PEX-A pipes resulted in inconsistent performance and eventual leaks. This costly lesson taught me that PEX-A’s unique properties genuinely require specialized fitting systems to achieve their full potential. Yes, PEX-A pipes require specialized expansion fittings that leverage the material’s molecular memory

Early in my career, I encountered a plumbing system where different contractors had installed PEX-A and PEX-B in the same building without proper transitions. The resulting leaks and connection failures cost thousands to rectify, driving home the critical question: why avoid mixing PEX-A and PEX-B systems?
