What is the requirement for the installation of distribution boxes?

The requirement that distribution boxes must be installed level is crucial for the proper functioning of a septic system. When distribution boxes are level, it ensures that effluent is evenly distributed to the drain field. This balance prevents overloading of specific areas, which could lead to soil saturation and system failure.

If a distribution box is installed at an angle or on an uneven surface, it can cause the effluent to flow unevenly, potentially overwhelming one section of the drain field while leaving others dry. This can lead to inefficient treatment of wastewater and can compromise the overall health of the septic system.

Overall, correct installation level is essential for maintaining proper flow and function, which contributes to the longevity and effectiveness of the septic system as a whole.
