We test and certify to much more than our two flagship industry standards, NSF/ANSI 14 for plastic piping systems and components and NSF/ANSI/CAN 61 for drinking water system components. Whether you manufacture valves, faucets, copper tubing, sinks, thermostatic mixing valves, backflow preventers, toilets, septic tanks, showers or practically any other type of plumbing product, our in-house laboratory is equipped and accredited to test to virtually all plumbing industry standards, including ASME, ASSE, ASTM, CSA and IAPMO. Once in the marketplace, all NSF-certified products are widely accepted by plumbing inspectors and code officials across North America. NSF issues the U.P. Code mark or cNSF mark upon certification.
