List at least two reasons why equipment would be indirectly connected to a drainage system.

Question

What will be an ideal response?

Answer 1

Choose from among the following partial list:
• Food located in or later placed in food preparation commercial sinks could not be
contaminated from waste backing up in a malfunctioning drainage system.
• Ice located in a storage bin would not be contaminated from waste backing up in a
malfunctioning drainage system.
• Insects or small animals could not enter the fixtures if they were indirectly
connected.
• If a negative pressure develops on a water supply line to an appliance such as a water
heater, the indirect waste maintains the integrity of the potable water system.
