What is the minimum water seal required for interceptors designed for heavy solids?

The minimum water seal required for interceptors designed for heavy solids is typically 6 inches. This dimension is important because it ensures that there is sufficient water barrier to effectively trap heavy solids and prevent them from passing into the drainage system. A deeper water seal can also enhance the interception of grease and solids, reducing the risk of blockages and ensuring that the interceptor functions properly.

In systems dealing with heavy solids, having a 6-inch water seal helps mitigate the risk of the solids floating or bypassing the trap, which could lead to inefficiencies and potential plumbing issues. The larger water seal depth provides added insurance against the movement of particulates and ensures that the interceptor remains effective in separating and containing contaminants before they enter the public sewer system or treatment facility.
