Compliance Services for Drinking Water System Components 

We provide the expertise and services that you need to meet the requirements of NSF/ANSI 61 (including Annex G) and NSF 372.

Water pump

Overview

Our comprehensive compliance services cover a wide range of products used in the transport of potable water, starting from a municipal water treatment facility to the network of water tanks and piping systems, which then connect to commercial and residential buildings.   

Benefits 

Our water systems certification program can certify anything that distributes potable water to your faucet.  Examples include: 

  • Joining and sealing materials including gaskets (EPDM, NBR SBR), lubricants and sealants (silicon, PTFE) 

  • Barrier materials including paints, coatings (asphalt, epoxy, polyurethane), cements, additives and tank liners 

  • Pipes (copper, ductile iron, stainless steel, concrete) including fittings, couplings, flexible and rigid tubing, and hoses 

  • Mechanical devices including service saddles, water meters, ball valves, pumps, chemical feeders and hydrants 

  • Plumbing devices including faucets, drinking fountains and refrigerator ice makers 

  • Process media including carbon, aluminum silicates, ion exchange resins and sand 

  • Plastic materials including ABS, nylon, polycarbonate, polyethylene and PVC 

For additional information, refer to our online directory of water system components currently certified to NSF 61. 

Leverage UL Certification to NSF 372, the Standard for Drinking Water System Components – Lead Content, to demonstrate compliance with the lead-free requirements in: 

  • California Health and Safety Code – Section 116875 

  • Vermont Lead Reduction Law (Vermont Act No. 193) 

  • Maryland House Bill 372 

  • Reduction of Lead in Drinking Water Act (RLDWA) Section 1417 

  • Uniform Plumbing Code Section 604.11 

  • Louisiana House Bill 471 

For additional information, refer to our online directory of water system components currently certified to NSF 372.  

Why UL 

Keeping public water works projects on schedule is critical for general contractors and engineering firms. We can help validate that locally sourced cement and aggregate materials do not have contaminants or impurities that may have adverse effects on human health. 

Our certification transfer program makes it easy for customers to upgrade to our services, and our global presence allows us to provide cost-conscious services around the world.

Webinar: Certification of Mechanical Devices Simplified

Is your product categorized as a mechanical device in NSF/ANSI Standard 61? If you are not sure or if NSF/ANSI Standard 61 is confusing you, this webinar is for you. During this free webinar you will hear from UL experts about the latest requirements in NSF 61 that affect Mechanical Devices such as valves.

Webinar: NSF 61 Barrier Materials: Potable Water 101 for Paints, Liners, Coatings, and Tanks

This presentation will be a general overview of Barrier Material type products (Paints, Liners, Coatings, and Tanks) with potable (drinking water) applications. The focus will be on NSF 61, but also cover NSF 372, NSF P151, and other applicable standards. Barrier materials are materials used to contain or form a barrier between water and another surface. Barrier Materials are used to form drinking water holding tanks or to line water reservoirs. Other distribution products such as pipes, fittings, and valves use paints and coatings as barrier materials as well.
