If a pump at a whirlpool bathtub is located more than 2 feet from the access opening, what is the minimum size opening that should be installed?

• A. 12 x 12 inches
• B. 18 x 18 inches
• C. 24 x 24 inches
• D. 30 x 30 inches

Answer: (B)

The correct choice is based on the requirement for sufficient access to perform maintenance and repairs on a pump located more than 2 feet away from the access opening. When dealing with components such as pumps in a whirlpool bathtub, it's essential to ensure that they are easily accessible to service personnel. An 18 x 18-inch opening provides adequate space for an individual to maneuver easily while working on or around the pump, ensuring that necessary repairs or inspections can be carried out safely and efficiently. This size strikes a balance between accessibility and the structural integrity of the surrounding area. Larger opening sizes might be more than necessary, leading to potentially higher costs and requiring more extensive modifications to structures, while smaller openings could hinder access and complicate any work needed, making the 18 x 18-inch dimension the standard minimum requirement in most plumbing codes.
