What must be the water level of outlet pips in an equal flow type distribution box?

The water level of outlet pipes in an equal flow type distribution box must be at the same level to provide equal flow. This is critical because an equal flow distribution box is designed to evenly distribute wastewater among the lateral lines, ensuring that all lines receive the same amount of effluent. If the outlet pipes are not at the same level, it could cause uneven flow, leading to some lateral lines being overloaded while others might be underutilized. This imbalance can contribute to inefficient system performance, potential backups, and localized failure of the septic system. Thus, maintaining an equalized water level in the outlet pipes is essential for the effective operation of the septic system.
