Certification promotes environmental stewardship
NSF Intl. announced that Charlotte Pipe and Foundry Co.’s RePVC (polyvinyl chloride) and ReUze can now be added to the company’s list of products certified by NSF Intl., an independent, not-for-profit organization committed to protecting and improving public health and the environment.
According to Charlotte Pipe, there are three sources of non-potable water: rainwater, graywater and municipally supplied reclaimed water. Non-potable water systems are ideal for applications that do not require water, and have been treated to drinking water standards.
NSF Intl.’s certification for water piping systems verifies that the products meet all applicable requirements by conducting thorough testing and facility inspections. This includes three unannounced inspections annually, formulation and manufacturing process reviews and testing of product samples.
ReUze, a purple CPVC piping system for distributing non-potable water inside the building, is aimed at increasing water efficiency. The line pipes are purple to differentiate non-potable water from potable water. Non-potable water can be used to save building owners money and preserve water in applications such as toilet and urinal flushing and process water.
RePVC is a PVC pipe that uses recycled content as the center layer. It expands the market for recycled materials, slows the consumption of raw materials and reduces the amount of waste entering landfills. RePVC is one of the first products to be certified by NSF Intl. to ASTM F 1760: Standard Specification for Coextruded Poly (Vinyl Chloride) (PVC) Non-Pressure Plastic Pipe Having Reprocessed-Recycled Content. ASTM F 1760 contains requirements for plastic pipe having recycled content.
Obtaining NSF certification was important to Charlotte Pipe.
“NSF certification means that your product will be recognized and respected by engineers, code officials, building owners and contractors,” said Greg Nahrgang, new product development manager for Charlotte Pipe.
He believes that one day all non-pressure piping will incorporate recycled content because it is the right thing to do for the environment.
“Third-party, conformity assessment is one of the best ways to ensure that a manufactured product complies with the standards,” he said.
“It is important that companies like Charlotte Pipe and Foundry are innovative and actively pursuing new sustainable applications to improve efficiency and reduce waste,” said Nasrin Kashefi general manager of NSF Intl.’s plumbing programs. “NSF certification provides engineers, regulators and users with assurance that products meet all applicable sustainability requirements. When they see the NSF mark on pipes, they know it has been NSF certified.”
