[Amended 1-28-1975]
No waste from a refrigerator or ice-flood drain
or any other receptacle where food is stored shall connect directly
with any house drain, soil or waste pipe. Such waste pipes shall,
in all cases, be open-dripped into an open sink properly supplied
with water, sewer-connected, trapped and vented. Such waste connections
shall not be inaccessible nor in unventilated cellars. Indirect waste
pipes shall discharge through an air break into a water-supplied sink
or into a water-supplied floor drain directly connected to the sanitary
drainage system and approved for such use.
Refrigerator waste pipes shall be not less than
1 1/4 inches and shall have cleanouts at all angles.
Waste pipes in dye houses, bottling works, creameries,
laundries and similar establishments where the wastes are highly diluted
may discharge into the sanitary sewer through an approved sanitary
drainage piping system.
