According to the text, which type of plumbing fixture should not receive the discharge of an indirect waste pipe if it is used for domestic or culinary purposes?

Urinal
Bathtub
Kitchen Sink
Dishwasher

The correct answer is: Kitchen Sink

The kitchen sink is the correct answer because it is used for domestic or culinary purposes, which means that any waste discharged from it could come into direct contact with food or food preparation areas. In plumbing design, any fixture that is involved in food preparation or washing should be protected from indirect waste connections to ensure that contaminants do not enter the food supply. Indirect waste pipes are typically used for fixtures that do not directly impact safe food handling, allowing for proper drainage while minimizing the risk of contamination. Although other fixtures like the urinal and bathtub are not typically associated with food, the kitchen sink is specifically designated for food-related tasks, making it essential to ensure that it does not receive waste in a manner that could compromise hygiene and safety.
