What is the purpose of a distribution box in a plumbing system?

The purpose of a distribution box in a plumbing system is to allow for even distribution of liquid to drain. This component is typically used in septic systems or similar setups where wastewater needs to be properly managed. The distribution box receives effluent from the septic tank and then disperses it evenly into multiple drain fields or leach lines. This ensures that the wastewater is spread out evenly across the ground, preventing the saturation of any one area and allowing for better absorption into the soil. Even distribution is essential for the system to function properly and to minimize the risk of backup or system failure.

In contrast, filtering out solids refers to different types of filtration systems, measuring water usage involves metering devices, and trapping gases is typically associated with traps in drainage systems, which are not the primary functions of a distribution box.
