What is the purpose of a waste receptor in plumbing systems?

A waste receptor plays a crucial role in plumbing systems as it is specifically designed to receive and properly direct the discharge from indirect waste pipes. This function is essential for maintaining efficient drainage and preventing potential issues related to overflow or backflow. Typically, a waste receptor can be found in various plumbing fixtures that are intended to collect wastewater from appliances that do not drain directly into a sanitary sewer system.

In contrast, the other choices do not align with the purpose of a waste receptor. For example, measuring liquid waste or treating wastewater are unrelated to the act of receiving and directing waste. Similarly, a water filter for drinking water serves a completely different function, focusing on purification rather than waste management. Thus, the role of a waste receptor is specifically centered around handling indirect waste effectively, which makes it integral to ensuring proper plumbing function and sanitation.
