DOMESTIC WATER PIPING – HOT WATER 22 11 16 - 1

SECTION 22 11 16 - DOMESTIC WATER PIPING – HOT WATER

PART 1 - GENERAL 1.01 DESCRIPTION OF WORK

A. Extent of hot water supply Work is indicated on the Drawings and by the requirements of this Section.

1.02 CODES AND STANDARDS

A. Comply with applicable portions of the Building Code of the City of New York, and the New York City/State Energy Conservation Construction Code (NYCECC/NYSECCC). Where requirements for products, materi-als, equipment, methods and other portion of the work specified herein exceed minimum requirements of N.Y.C. Building Code, the Contractor shall comply with such requirements specified herein, unless specifically approved otherwise by the Authority.

B. 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, plumb-ing fixtures and faucet is the new section of the law that re-quires 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 sur-face 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 con-tent of the material used to produce wetted components shall be used to determine 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 calcula-

tion, the contractor may choose to demonstrate compliance with the act by requiring from manufacturer documentation certifying that products are lead free based on either calcula-tion or tests or third party certification.

3.05 DRAINAGE AND VENT PIPING INSIDE BUILDING

A. Rough Plumbing: The piping of plumbing drainage and venting system shall be verified as to material and shall be tested upon completion of the rough piping installation and proven to be watertight. The representative of the local agency having jurisdiction may require the removal of any cleanout plugs to ascertain that the prescribed pressure has been reached in all parts of the system.

1. Water Test

A water test shall be applied to the drainage system which includes soil, waste, leader and vent piping either in its entirety or in sections after rough piping has been installed. If applied to the entire system, all openings in the piping, except the highest opening, shall be tightly closed and the system filled with water to the point of overflow. If the system is tested in section, each opening, except the highest opening of the sections under test, shall be tightly plugged and each section filled with water. No section shall be tested with less than a 10 ft., head of water. In testing successive sections, at least the upper 10 ft., of the following section shall be tested, so that no joint or pipe in the building (except the uppermost 10 ft., of the system) shall have been submitted to a test of less than 10 ft., head of water. The water shall be kept in the system or in the portion under the test for at least 15 minutes before inspection starts; the system shall then be tight at all points.

B. Finished Plumbing: After the plumbing fixtures have been set and their traps

filled with water the entire drainage system shall be verified as to materials and shall be tested and proven gas tight by smoke test.

1. Final Drainage and vent test:

A smoke test, if deemed necessary by the Plumbing Inspector, shall be performed when the visual final test of the completed drainage and vent system is not in sufficient detail to determine that testing and inspection are in compliance with the NYC plumbing Code. When the smoke test is utilized, it shall be made by filling all traps with water and then introducing into the entire system a pungent thick smoke produced by one or more smoke machines. When the smoke appears at stack openings of the roof, these openings shall be closed and a

Within that period, no visible water leak shall be observed around the exposed joints of the piping network. For proper support and for ease of installation, corrugated HDPE piping assembly shall be surrounded with 6” compacted fill, leaving only the top of all joints exposed prior to the test. A drop in water elevation within the inspection riser pipe shall not be construed as an automatic failure since the pipe liner tends to stretch and deform over time, thus giving a false sense that the pipe is leaking.

Water testing of HDPE piping shall be considered a failure when a sustained and noticeable water leak is seen at the joints.

D. In lieu of the testing protocol outlined above, when checking a totally

backfilled HDPE piping installation (excluding the joints that must remain exposed), testing requirements based on ASTM-C969 shall be utilized. As per the ASTM standard, an allowable leakage rate consisting of 200 gallons per inch per internal diameter per mile of sewer within a 24-hour period, shall form the basis for accepting or rejecting fully covered HDPE piping, including all joints.

A. Provide all required plumbing fixtures and associated supports as specified herein. The extent of fixture and trim work is as indicated on the Drawings and by the requirements of this Section.


A. Comply with applicable portions of: the Building Code of the City of New York; Local Law 58 of 1987, Local Law 29 of 1989, Local Law 86 of 2005, Local Law 57 of 2010; ANSI Code; ASSE Standards; UL 1951 Electric Plumbing Accessories; N.Y. State Department of Environmental Conservation Law performance standards specified in Section 15-0314, including all administrative decisions.

B. 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.

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 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.

1.03 SUBMITTALS

A. Submit shop drawings for the following:

1. Fixtures 3. Trim, faucets, mixing valves etc. 4. Fixture Supports
