Assess Existing Dishwasher Drain Setup

What happens here

The video shows the underside of a kitchen sink with a garbage disposal and a P-trap. The dishwasher drain hose is visible running horizontally at a low point, which is incorrect as it allows potential backflow. Additionally, the garbage disposal itself is noted to be loosely installed, which could lead to leaks or detachment over time. The primary focus of this step is to understand these existing deficiencies before correction.

Goal: The presenter identifies two primary issues with the current dishwasher drain setup: an improperly low drain hose and a loose garbage disposal mounting.
