When installing a food waste disposal system in a double sink, using a directional tee is important for proper drainage. The directional tee is designed to manage the flow of wastewater effectively. It allows for the waste to flow from the disposal into the drain line while simultaneously preventing waste water from being pushed back into the other sink compartment when the disposal is in use. This is crucial because if waste from one sink backs up into the other, it can lead to unpleasant odors, clogs, and hygiene issues.

The directional tee helps to direct the flow of water in a specific direction, facilitating smooth drainage without the cross-contamination of waste between the sink compartments. This setup ensures that each compartment functions properly, maintaining effective drainage and hygiene in the kitchen environment.
