Indirect waste to sanitary waste line maximum developed length is how many feet?

• A. 3 feet
• B. 6 feet
• C. 7 feet
• D. 5 feet

Answer: (D)

Indirect waste piping must stay within a short distance to the sanitary waste line so the system can vent properly and maintain an effective air gap or receptor arrangement. The maximum developed length for this connection is five feet, measured along the actual pipe run from the indirect waste outlet to the point it joins the sanitary waste line. Keeping it to five feet helps prevent issues like siphonage or backflow and ensures the waste discharges into the proper receptacle or drain promptly. If more length were needed, the installation would require a different configuration to preserve venting and the integrity of the waste system.
