Geothermal Plastic Piping Systems Certification
Most U.S. state and Canadian province drinking water regulations require pipes and fittings conveying drinking water to meet the requirements of NSF/ANSI/CAN 61 to ensure components will not contribute harmful levels of contaminants to the drinking water.
What is NSF/ANSI/CAN 61?
NSF/ANSI/CAN 61: Drinking Water System Components -Health Effects is the American National Standard and the Canadian National Standard that establishes the health effects requirements for chemical contaminants and impurities that are indirectly imparted to drinking water from products, components, and materials used in drinking water systems.
How do I know if HDPE pipes or fittings meet this NSF requirement?
HDPE pipes or fittings certified by NSF will bear either the NSF®-61 mark or the NSF® pw (potable water) mark on the print string. The NSF® pw mark indicates the product meets the health requirements of NSF/ANSI/CAN 61 as well as performance, long-term strength, and quality control requirements in NSF/ANSI 14: Plastic Piping Components and Related Materials.
