Section XIV-617 - Water Supply Control

A. Valves Required. An accessible shutoff valve shall be provided on the consumer's premises ahead of the first outlet or branch connection to the service or distribution pipe of each dwelling, dwelling unit and buildings other than dwellings and dwelling units. Full port ball valve shut-offs on lines to 2 inches or full port ball or resilient wedge-type shut-off valves for 2 1/2-inch lines and larger shall be used. When such shutoff valve is located in the service pipe outside the building, it shall be located and accessible in a manufactured, approved, valve box with a readily removable access cover which extends to grade_(G) level. When drain valves are provided for the distribution piping or other portions of the water distribution system, such drains shall be above grade_(G) or otherwise located to prevent the possibility of backflow into the piping system after the system has been drained.

B. Tank Controls. Supply lines taken from pressure or gravity tanks shall be valved at or near the tank.

C. Controls for Fixtures Within Dwellings and Dwelling Units. Each individual fixture shall have an accessible shutoff valve at each outlet which will permit each fixture to be shut off without interfering with the water supply to any other fixtures. Shutoff valves for each fixture supplied by a manifold distribution system may be located at the manifold in addition to the outlet of the fixture being supplied. The hose bibb or hose connection shutoff valve shall be the only shutoff valve required on washing machine connectors.

1. Shutoff valves to water supply for refrigerators with automatic ice makers shall be accessible on the same floor.

D. Controls for Fixtures in Buildings Other Than Dwellings or Dwelling Units. In all buildings other than dwellings and dwelling units, shutoff valves shall be installed which permit the water supply to all fixtures and equipment in each separate room to be shut off without interference with the water supply to any other room or portion of the building or each individual fixture and piece of equipment shall have a shutoff valve which will permit each fixture and piece of equipment to be shut off without interfering with the water supply to other fixtures or equipment.

1. Each water supply branch line 1 1/2-inch or larger shall have a shutoff valve installed so as to isolate all fixtures and all pieces of equipment supplied by the branch line. The shutoff valve shall be installed in a labeled and accessible location as close to the connection to the supply main and/or riser as practical.
