Wilkins becomes first backflow preventer manufacturer certified by NSF to new lead requirements
September 23rd, 2009Ann Arbor, Mich. — As of January 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 Company, 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.
Backflow preventers are mechanical plumbing devices that protect against pollution and contamination by preventing unsafe water from flowing back into the public water supply.
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 January 1, 2010. 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.
The lead content requirements of Section 116875 of the California Health and Safety Code (also known as AB1953) were incorporated as an annex into the American National Standard for health effects of drinking water system components NSF/ANSI Standard 61: Annex G – Weighted Average Lead Content Evaluation Procedure to a 0.25 Percent Lead Requirement.
To obtain certification, Wilkins demonstrated compliance with all of NSF/ANSI Standard 61, Annex G requirements.
