Indirect wastes shall be required for the discharge of all waste
from:
A.
Any refrigerator, icebox, steam table, bar or soda fountain, swimming pool, swimming pool scum gutter or any receptacle, appliance, device or apparatus which is used for the storage, preparation or processing of food or drink. In a three-compartment bar or soda fountain sink, the ice compartment shall be separately trapped and installed as an indirect waste line. The other two compartments may be connected with a continuous waste or individual traps and waste lines installed as indirect waste lines, in accordance with this article. All drip waste lines shall conform to § 131-84E.

B.
Any appliance, device or apparatus using water as a cooling or heating
medium.
C.
Any sterilizer, water still or other similar appliance, device or
apparatus.
D.
Any water treatment device, including filters and softeners.
E.
Any water-operated device.
F.
Any drain, overflow or vent from a water supply system.
G.
Any drain for condensate or defrosting evaporators in air-conditioning
systems or having inlet in the air stream of ventilating or air-conditioning
systems.
H.
Any other device, when required by the Plumbing Inspector or Health
Inspector.
A.
Installation. Indirect waste pipes shall be installed in conformity
with the provisions of these rules and regulations governing sanitary
drainage piping.
B.
Discharge of indirect wastes. Indirect waste pipes shall discharge
into and above the flood level of a trapped open sink or approved
receptacle, properly supplied with water, which shall be vented where
required by these rules and regulations and which shall be located
in an accessible, ventilated place, with an air gap between the outlet
end of the waste pipe and the flood-level rim of the receiving sink
or approved receptacle. The air gap in each instance shall be at least
twice the diameter of the indirect waste pipe. If the indirect waste
has sufficient year-round flow to maintain the trap seal, the sink
or receptacle need not be supplied with water.

C.
Discharge of clear water wastes. Water lifts, expansion tanks, cooling
jackets, drip or overflow pans or similar devices which waste clear
water only may discharge onto a roof, into a sump or so as to drain
into a trapped fixture or receptacle. Drains from sprinkler systems
shall be discharged onto a roof, into a sump or over an open trapped
outlet of sufficient size to permit maximum flow from the drain under
full system pressure without overflowing.
D.
Location of trapped fixtures or receptacles receiving indirect wastes.
Fixtures or receptacles receiving indirect wastes shall not be located
within living quarters, and no indirect waste shall discharge into
a lavatory, water closet, urinal, bathtub, shower, drinking fountain
or other similar fixture in use for its customary purpose.
E.
A drain for receiving condensate from air-conditioning systems may
discharge into a laundry tray fixture or service sink fixture in accordance
with this section. In one- and two-family residences, the condensate
water may discharge onto a seeded area that is part of the property
where the air-conditioning system is located.
A.
Materials. Pipes, stacks, vents and connecting joints conducting
or otherwise in contact with corrosive waste shall be constructed
of materials approved by the Plumbing Inspector as capable of resisting
the destructive action of such wastes.
B.
Treatment.
(1)
Corrosive, toxic or injurious wastes shall not be discharged
into a street sewer unless first treated, diluted or neutralized in
accordance with the regulations of the Delaware County Regional Water
Quality Control Authority and the Pennsylvania Department of Environmental
Resources to prevent injury to the public sewer system and treatment
works.
(2)
No waste containing radioactive substances shall be discharged
into any portion of a plumbing system.
(3)
Corrosive, toxic or injurious wastes or sanitary sewage not discharged into the public sewer system or as prescribed in Article XIV shall be conveyed in a manner approved by the Health Inspector and treated, diluted, neutralized and disposed of in accordance with the regulations of the Health Code of the Borough of Parkside and Pennsylvania Department of Environmental Resources to ensure efficient and sanitary disposal and to prevent stream pollution, discharge to the ground surface of contaminating substances, creation of offensive odors, contamination of water supplies and the creation of health hazards and nuisances.
No indirect waste pipe shall exceed 100 feet in length without
venting.
Indirect waste stacks receiving the discharge from fixtures on more than one floor, indirect wastes exceeding 100 feet in length and indirect wastes draining more than one trapped fixture shall be vented by being extended to the outer air above the roof as required by Article XI.

The size of waste pipes from refrigerators shall be as indicated in § 131-84D(4), Table P-1.
