The top of the gravel, gravelless pipe or chamber system should be located how many inches below the invert of the septic tank outlet?

• A. 0.5 Inches
• B. 1 Inch
• C. 2 Inches
• D. 3 Inches

Answer: (B)

The correct answer indicates that the top of the gravel, gravelless pipe, or chamber system must be situated 1 inch below the invert of the septic tank outlet. This specification is crucial for the effective functioning of a private sewage system. Positioning the system at this depth ensures that there is adequate flow of effluent from the septic tank into the distribution system. When the gravel or pipes are set 1 inch below the outlet, it facilitates proper drainage and allows gravity to assist in the distribution of the effluent into the drain field. This depth helps to prevent backflow and maintains consistent flow throughout the system, thereby promoting optimal operation and minimizing the risk of clogs or backups. Understanding the importance of this measurement is essential for anyone involved in the installation or maintenance of septic systems, ensuring compliance with local regulations and promoting system longevity.
