Faucets and Plumbing

We have many choices when selecting products for home plumbing applications. Whether you are looking for a new kitchen faucet or replacing or repairing an old water line, NSF certification programs can help make the product selection process easier.

What Does NSF Certification Cover?

Certification of plumbing products and materials helps confirm that they meet applicable American or international standards for a particular use. While some products and materials are intended for drinking water use, others should only be used for special functions such as radiant floor heating or wastewater applications.

Faucets and plumbing products intended for contact with drinking water should be tested and certified to NSF/ANSI Standard 61: Drinking Water System Components. This American National Standard limits the amount of impurities that individual products can introduce into a home’s water supply, including lead and other metals, volatile organic chemicals, phthalates and bisphenol A (BPA). Products covered by this standard include faucets, pipe, drinking water fountains, water meters and water storage tanks. Products certified to this standard usually bear a certification mark such as “NSF 61” or “NSF pw.”

NSF also certifies water treatment, distribution and plumbing products against international regulatory, testing and certification requirements in more than 25 global markets including the UK, Australia, Brazil, China, Italy, France and Japan.

NSF also tests plumbing products for non-potable water use, including for wastewater, venting, radiant floor heating and geothermal applications. These products are evaluated and certified under NSF/ANSI Standard 14: Plumbing Products and will bear a special certification mark to indicate the end use application.

Before beginning any plumbing project, be sure to check with your local building/plumbing officials to determine what products and materials are permitted under local plumbing codes.
