At what approximate height should the fittings for a food waste disposer be installed above the finished floor?

6 inches through 9 inches
10 inches through 12 inches
12 inches through 15 inches
16 inches through 18 inches

The correct answer is: 12 inches through 15 inches

The appropriate height for installing fittings for a food waste disposer is typically within the range of 12 inches to 15 inches above the finished floor. This height is recommended to ensure proper drainage and convenience during installation and maintenance. Having the fittings at this height allows for sufficient clearance and accessibility while complying with local plumbing codes related to food waste disposers. Additionally, this range helps prevent potential obstructions that could arise from the flooring or cabinetry situated below the disposer. By adhering to this guideline, plumbers can ensure optimal functionality of the food waste disposer, reducing the likelihood of clogs and other plumbing issues associated with improper installation heights.
