Corzan® CPVC Is the Non-Metallic Option for Water Quality

Understanding the capabilities of engineered piping materials not typically covered in college curricula can be a daunting task for plumbing engineers. For those interested in considering alternative materials to copper, such as CPVC, that knowledge is best acquired by doing one’s own research into performance properties and product testing and reaching out to manufacturers’ specialists to further unlock insights.

The experts behind Corzan® CPVC Piping Systems know that specification expertise in non-metallic piping systems for commercial buildings can be difficult to come by if you don’t know where to look. That’s why all of the resources a specifier might need to evaluate reliability are now in one central location on our website. We’ve organized the page to help specifiers assess their options with the two largest considerations: design basics and ever-expanding concerns associated with safeguarding water quality.

Specifiers will find out how to overcome the shortcomings of metallic piping materials, and discover how piping made with Corzan CPVC provides an unparalleled solution to corrosion, scale buildup, and the associated reduced flow area, along with concerns about biofilm growth and the risk of Legionella-based illness. The solution is all in one NSF/ANSI/CAN 61-compliant material.

For example, as a material with natural resistance to corrosion, Corzan CPVC is compliant with NSF/ANSI/CAN 61 under all conditions and temperatures, but the same cannot be said of copper. If a water supply’s pH falls below 6.5, copper piping may leach metallic contaminants above the recommended limit for safe drinking water, requiring extra corrosion control measures of the associated water supply to curtail its solubility.

The next time you need a pipe sizing tool, a thermal expansion calculator, and an insulation guide, and you also want to learn about municipal water chemistry, using Corzan CPVC in hot water riser systems, and reducing the risk of Legionella growth in piping, it’s all aggregated in one place.
