Which feature is required for a grease trap?

A grease trap must be vented to function properly. Venting is crucial because it allows for the escape of gases generated during the decomposition of grease and food waste. This prevents the buildup of pressure within the trap, which can disrupt its operation and lead to failures in grease separation. Additionally, proper venting helps maintain the effectiveness of the trap by ensuring that it operates at the correct atmospheric pressure, thereby allowing for adequate flow and separation of the grease from wastewater.

While other features, such as being electric or having a manual reset, may be present in certain designs, they are not universally required for all grease traps. Similarly, the location of the trap, whether indoors or outdoors, does not dictate its fundamental operation regarding grease removal; however, local codes may influence specific installation requirements. The primary function of venting directly impacts the grease trap's ability to efficiently separate fats, oils, and grease from wastewater, making it a vital requirement.
