Viscoelastic Weaknesses of Plastic Pipes

Engineering studies and forensic reviews show plastic pipe materials have mechanical behaviors very different from metals. These behaviors introduce long-term performance concerns that designers and contractors must account for when designing systems and specifying materials.

Field-Tested Truths

Piping managers across the U.S. shared their professional observations based on what did and did not work for their systems over the course of years and decades of use.

Leaching of Microplastics & Chemicals from PEX Pipes

PEX and other plastic piping systems leach plastic particles & chemicals, posing significant concerns for drinking water quality. Until we have more studies and better oversight, architects and others must weigh risks to occupants.

Research Shows Risks of Plastic Pipes in Fires

Recent fire testing from the Copper Sustainability Partnership (CuSP) reinforces our findings that combustible plastic plumbing materials pose significant risks in fire conditions.
