Section 890.1190  Water

Supply Control Valves and Meter

a)         A full-port shut-off valve shall be located near the curb or

property line and immediately inside the building, on the inlet and outlet side

of the water meter.  When located underground, this valve shall be in a stop

box or meter vault.  (See Appendix I.Illustration H.)

b)         The utility meter may be installed outside in an accessible

meter vault or within the building.  The meter shall have unions on the inlet

and outlet openings.  A full-port valve with an open area at least that of the

water service shall be provided for all meters and shall be provided with a

drain valve installed on the discharge side of the meter valve when located

inside of a building.  (See Appendix I.Illustrations H and I.)

c)         Tank Controls.  Supply lines taken from pressure or gravity

tanks shall be valved at or near their source.

d)         Water Heating Equipment.  A shut-off valve shall be provided

in the cold water branch within 5 developed feet of each water storage tank or

each water heater and located in the same room.

e)         Separate Controls for Each Family Unit.  In multiple family

dwellings, the water service or water distribution pipe to each family unit

shall be controlled by an arrangement of line valves that permits each group of

fixtures and each individual fixture to be shut off without interference with

the water supply to any other family unit or portion of the building.  The

location of these valves shall be uniform in each family unit of a multiple

family dwelling.  (See Appendix I.Illustration J.)

f)         Buildings Other Than Dwellings.  In all buildings other than

dwellings and health care facilities as specified in subsection (g), line

valves shall be installed to permit the water supply to all equipment or

fixtures in each separate room to be shut off without interfering with the

water supply to any other room or portion of the building

dwelling.  (See Appendix I.Illustration J.)

f)         Buildings Other Than Dwellings.  In all buildings other than

dwellings and health care facilities as specified in subsection (g), line

valves shall be installed to permit the water supply to all equipment or

fixtures in each separate room to be shut off without interfering with the

water supply to any other room or portion of the building. For plumbing

equipment or fixtures that are installed back-to-back in adjacent rooms, e.g.,

in adjacent restrooms, a common line valve may be used to shut off the water

supply to the back-to-back fixtures in no more than two adjacent rooms. (See

Appendix I.Illustration K.)

g)         Health Care Facilities.  In the residence rooms of health care

facilities, the water distribution pipe to each resident unit shall be

controlled by an arrangement of line valves that permits each group of

fixtures, and each individual fixture, to be shut off without interference with

the water supply to any other unit or portion of the building.
