What is the minimum water seal depth required for a grease interceptor?

The minimum water seal depth required for a grease interceptor is 2 inches. This specification is crucial because the water seal serves to create a barrier that prevents odors and gases from escaping the interceptor into the surrounding environment. A sufficient water seal depth ensures that the grease interceptor operates effectively by creating an adequate trap for grease and other solids while allowing wastewater to flow through.

If the water seal depth were less than 2 inches, it could lead to an increased risk of odor problems and could compromise the functioning of the interceptor, as it might not effectively trap the grease and solids. Further, maintaining the correct water seal depth is essential for compliance with plumbing codes, which are designed to ensure proper sanitation and functionality in wastewater management systems.
