This standard describes only iron-body unassisted swing-check valves, 2-in. through 48-in. (50-mm through 1,200-mm) NPS, with mechanical-joint or flanged ends that are installed in approximately level settings in water systems.

This standard describes essential procedures for the replacement of lead water service lines and flushing following replacement. This standard also describes procedures for partial replacement and repair situations where complete lead service line replacement is not possible or practical.

This standard describes the use of sodium metabisulfite (Na2S2O5) in the treatment of potable water, wastewater, and reclaimed water.

This standard describes the double check-valve backflow prevention assembly for potable water applications. The assembly shall be capable of withstanding a working water pressure of at least 150 psi (1,034 kPa) without damage to working parts or impairment of function and for operation on hot or cold potable water lines.

This standard describes the reduced-pressure principle backflow prevention assembly for potable water applications. The assembly shall be capable of withstanding a working water pressure of at least 150 psi (1,034 kPa) without damage to working parts or impairment of function and for operation on hot- or cold-water lines.

This standard describes the critical requirements for the effective operation and management of drinking water treatment plants.

This standard describes gravel, high-density gravel, silica sand, high-density media, anthracite filter materials, and the placement of the materials in filters for water supply service application. ANSI/AWWA B604, Standard for Granular Activated Carbon, addresses use of GAC as a filter medium and as an adsorbent.

This standard describes hydraulic and pneumatic cylinder and vane-type actuators for operation of valve and slide gates in utility systems.

This standard describes electric motor actuators that are externally mounted on gate, ball, plug, cone, globe, and butterfly valves and on slide gates suitable for use in water, wastewater, and reclaimed water facilities.

This standard describes resilient-seated cast-iron eccentric plug valves, 3 in. (75mm) through 72 in. (1,800 mm) in diameter, with flanged, grooved, or mechanical-joint ends.
