When installing a food waste disposal onto a double bowl sink, the disposal should be installed with a 'baffle tee' to direct waste in which direction?

• A. Direct waste upward
• B. Direct waste to the left
• C. Direct waste to the disposal
• D. Direct waste downward

Answer: (D)

The main idea is that the garbage disposal sits below the sink, so waste must be directed downward into the drain system. A baffle tee is used to route the flow from the sink into the disposal and then down toward the trap, ensuring gravity helps move the waste and preventing backflow into the other basin. Directing waste in any other direction would fight gravity and increase the risk of leaks or backups, so this setup requires the waste to go downward.
