Current through Register Vol. 48, No. 28, July 12, 2024
New or repaired potable water systems shall be flushed or
				  disinfected prior to use as follows:
a) Chlorinated Water Supply. If the potable
				water supply serving the water supply system is chlorinated, e.g., a community
				water system, the water supply system, or appropriate repaired portion, shall
				be flushed with clean, potable water until no dirty water appears at the point
				of outlet.

				level in the water discharging from the system is within acceptable limits for
				potable water, i.e., generally until the water has no detectable chlorine
				odor.
3) To ensure that the water
				supplied by the water system is safe for drinking, a bacteriological
				examination of a water sample taken from the water supply system shall be
				secured. This examination shall be performed by a laboratory certified in
				accordance with 77 Ill. Adm. Code 465. The chlorine residual in any water
				sample collected for examination shall not exceed 4 parts per million (or 4

				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

e) Extensions Outside Building. No soil,
				waste or vent pipe extension (except for vent terminals as provided in
				subsections (b) and (d) of this Section() shall be located on the outside of a
				wall of any building, but shall be installed inside the building. Wet vents
				located within an exterior wall or in a wall adjacent to an unheated space
