What should be the focus when installing an interceptor?

When installing an interceptor, the primary focus should be on ensuring it can handle the maximum expected flow. Interceptors, such as grease traps or oil separators, are designed to manage and process wastewater that contains pollutants. By focusing on the maximum expected flow, you are prioritizing the system's ability to function effectively under peak load conditions. This helps prevent overflow and ensures that pollutants are adequately intercepted before they enter the sewage system, thereby protecting the environment and adhering to local regulations.

While costs, depth requirements, and accessibility for maintenance are important considerations, they are secondary to the interceptor's capacity to manage the expected flow. If an interceptor is undersized for the maximum anticipated flow, it could lead to operational failures, environmental hazards, and costly repairs down the line. Thus, ensuring that the interceptor can handle the maximum expected flow is crucial for its overall efficacy and compliance with plumbing codes.
