What is the minimum size of vents on an oil interceptor?

The minimum size for vents on an oil interceptor is 1-1/4 inches. This specification is important to ensure proper ventilation within the interceptor, which is critical for the effective operation of the system. Adequate venting allows for the release of gases that may accumulate, thereby preventing pressure build-up that could lead to mechanical failure or improper functioning.

Furthermore, using a vent size of 1-1/4 inches strikes a balance between being sufficiently large to handle vapor and air flow while also conforming to standard plumbing practices in the context of oil interceptors. This size aligns with building codes and safety regulations that govern oil interceptors, ensuring optimal performance and safety factors for both installers and users.

The other sizes would not meet the minimum requirement needed for safe and efficient operation in this context, highlighting the importance of adhering to the specified standards.
