What is the minimum trap seal required on a Type 1 interceptor?

The minimum trap seal required on a Type 1 interceptor is specified as 8 inches. This dimension is critical for ensuring proper functionality of the interceptor, which is designed to prevent grease and other waste materials from entering the wastewater system. The 8-inch trap seal helps maintain a sufficient barrier to block odors and gases from coming back into the building while still allowing for effective drainage.

The Type 1 interceptor must also comply with plumbing codes and standards that dictate these specifications to ensure the health and safety of the building's water systems. Inadequate trap seals may lead to odor issues and can compromise the effectiveness of the interceptor, hence the reason for the 8-inch requirement.
