NSF International approved Charlotte Pipe and Foundry Company’s RePVC (polyvinyl chloride) and ReUze for certification under NSF”s water piping systems program. Charlotte Pipe”s ReUze piping system is designed to increase water efficiency while RePVC is a PVC pipe that uses recycled content as its center layer.

NSF International’s certification for water piping systems verifies that the products meet all applicable requirements by conducting testing and facility inspections, including three unannounced inspections annually, formulation and manufacturing process reviews, and testing of product samples.

ReUze is a purple CPVC piping system for distributing non-potable water inside the building, which is directly aimed at increasing water efficiency. The line pipes are purple to differentiate non-potable water from potable water. According to Charlotte Pipe, non-potable water can be used to save building owners money, relieve stress on already over-burdened public agencies and preserve a precious resource in applications such as toilet and urinal flushing and process water.

RePVC 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 International 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.
