North American Code Requirements for Plumbing Products

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, NSF provides the testing and certifications you need to gain product acceptance and code compliance across North America.

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 61 for drinking water system components. 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.

Benefits of Certification

NSF certification ensures your product meets regulatory requirements for plumbing products across North America. Additionally, we can use your test data to certify your product to other industry standards, such as ASME, ASSE, AWWA, CSA, IAPMO, ISO and UL among others.
