NSF Annex G certification supports new requirements for low-lead plumbing products, which take effect Jan. 1, 2010.

As of Jan. 1, 2010, new lead content requirements in California (commonly known as AB 1953) will mandate a maximum weighted average lead content of ≤ 0.25 percent for plumbing products. Wilkins, a Zurn Co., reports it is the first backflow preventer manufacturer certified by NSF International to NSF/ANSI Standard 61: Drinking Water System Components -- Health Effects and Annex G low-lead requirements, developed to help protect the public from exposure to lead.

Manufacturers of backflow preventers for potable water service, faucets, valves, water fittings and other products that come in contact with drinking water must meet the new lead requirements, as set forth in the California Health and Safety Code, by the January deadline. After this date, any pipe, fitting or fixture intended to convey or dispense water for drinking or cooking must meet a weighted average lead content of ≤ 0.25 percent.

For meeting these requirements, Wilkins’ backflow preventers bear the NSF Annex G Certification Mark. Wilkins is also listed on the NSF Web site to demonstrate compliance with the new requirements.
