Understand Overflow Functionality

What happens here

For sinks equipped with an overflow, this drain assembly intelligently handles excess water. When the water level rises to the overflow, it will come down a secondary basin channel. From there, it hits the sidewall of the brass body of the drain and flows down through one of the four internal ports. This design ensures that the sink will operate correctly and drain efficiently, whether an overflow feature is present or not, providing reliable water management.

Goal: The video explains how the drain assembly manages overflow water by directing it down a secondary basin and through internal ports, ensuring proper drainage regardless of an overflow presence.
