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
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.
