PART 1 GENERAL 1.01 DESCRIPTION OF WORK SECTION 22412 VALVES A. Extent of Valve Work is indicated on the Drawings and by the Requirements of this Section. B. All valves, except those are 2 in diameter and larger, that convey drinking water for human consumption must be certified for meeting the requirements of the federally mandated Reduction of Lead in Drinking Water Act of 2014 (not more than a weighted average of.25% lead). Regardless of the valve manufacturer listed in these specifications, provide valves that meet the requirements of the act. All solder used during installation of valves associated with the potable water system designed for human consumption must also meet the requirements. 1.02 SUBMITTALS A. Product Data 1. Manufacturer's product technical data for each valve. 2. Installation Instructions 3. Include list indicating valve and its application B. Shop Drawings indicating methods of assembly of components. C. Certifications 1. Lead free Certifications: Provide manufacturer s certifications that valve in contact with the potable water, except those that are exempted, meet the requirements of the Reduction of Lead in Drinking Water Act effective Jan 4, 2014. 1.03 CODES AND STANDARDS VALVES 22412 1
A. The contractor shall comply with the Reduction of Lead in Drinking Water Act. Beginning on January 4, 2014, a federal law known as Reduction of Lead in Drinking Water Act takes effect. This law requires that faucet, plumbing fixtures, pipe and pipe fittings must conform to lead free criteria level whenever these plumbing related products are employed for delivery of potable water for human consumption. 1. The law makes it unlawful for any person, including a contractor, to introduce into commerce any pipe, pipe fitting, plumbing fixture, faucet that is not lead free. a. Lead free content is intended to mean not more than 0.2% lead when applied in connection to solder and flux and not more than 0.25 percent of the weighted average of lead when used with respect to the wetted surfaces of pipes, pipe fittings, plumbing fixtures and faucets. b. The section of the federal act that applies to solder and flux, 0.2% lead content, went into effect back in August of 1998; and for the most part soldering product being sold in today s market complies with the law. c. The requirement for.25% weighted average of lead when applied to the wetted surfaces of pipes, pipe fittings, plumbing fixtures and faucet is the new section of the law that requires special attention from a contractor. 2. To ensure compliance with Reduction of Lead in Drinking Water Act, a procedure for determining lead content was developed. The calculation procedure works as follows: a. For each wetted component, the percentage of lead in the component shall be multiplied by the ratio of the wetted surface area of that component to the total wetted surface area of the entire product to arrive at the weighted percentage of lead of the component. The weighted percentage of lead of each wetted component shall be added together, and the sum of these weighted percentages shall constitute the weighted average lead content of the product. The lead content of the material used to produce wetted components shall be used to determine VALVES 22412 2
PART 2 PRODUCTS 2.01 MATERIAL compliance with paragraph (1)(B) [Paragraph 1B Describes 0.25% Requirement For 0.25 % Lead Content] b. As an alternative to implementing the lead content calculation, the contractor may choose to demonstrate compliance with the act by requiring from manufacturer documentation certifying that products are lead free based on either calculation or tests or third party certification. A. Maximum content of lead permitted in materials used in the manufacture of valves shall be 5%. B. All valves shall be designed for packing under pressure with valve open or closed. C.
