Shutoff valves shall be installed in the following locations:
1. On the fixture supply to each plumbing fixture other than bathtubs and showers in Group R occupancies, and other than in individual dwelling units or sleeping units that are provided with unit shutoff valves or shutoff valves for each bathroom group;
2. On the water supply pipe to each sillcock;
3. On the water supply pipe to each appliance or mechanical equipment; and
4. On water services 1 1/2 inches (40 mm) or larger requiring meters either in the building or in a meter vault, valves shall be installed on the inlet and outlet sides of the meter and as near as practicable thereto. Meters on 1-inch (25 mm) services have a valve on the inlet side only. Valves located in the meter vault shall not eliminate the need for the valve in the building. All such valves shall be accessible for operation at all times.
