What are the two critical points of a grease interceptor regarding water flow?

The two critical points of a grease interceptor regarding water flow are the inlet and outlet. The inlet is where wastewater enters the grease interceptor, allowing grease and solids to separate from the water as it flows through the system. The outlet is where the treated water exits the grease interceptor to continue its journey to the wastewater treatment system.

Understanding the functions of these two points is essential for maintaining the efficiency of the grease interceptor. Proper flow through the inlet and outlet ensures that grease is effectively captured and does not clog other components of the plumbing system, contributing to better hygiene and compliance with environmental regulations.

In contrast, the other options do not accurately represent the critical points related to water flow in a grease interceptor. The top and bottom refer to the physical structure of the interceptor but do not denote flow pathways. The front and back may refer to orientation but lack relevance to how wastewater is treated. Similarly, the valve and drain could exist in the maintenance context but do not specifically indicate the critical points of water flow.
