Question 96

Pipe A is BEST defined by the Code as a fixture branch.

A fixture branch refers to the piping that connects a plumbing fixture to the drainage system, and in this context, Pipe A serves this specific function in accordance with the Code.

A) waste pipe

A waste pipe is designed to carry wastewater away from fixtures; however, it is not specifically defined to connect a fixture to the drainage system as directly as a fixture branch does. Therefore, while related, this option does not accurately represent the definition of Pipe A.

B) fixture branch

A fixture branch is the correct term for Pipe A, as it specifically refers to the pipe segment that connects a plumbing fixture to the main drainage system. This definition aligns perfectly with the requirements set forth by the Code, making it the best choice.

C) continuous waste

A continuous waste is a type of piping used to connect multiple fixtures to a single waste outlet, but it does not specifically define Pipe A as it is focused on the connection of several fixtures rather than a single fixture's connection to the drainage system.

D) horizontal branch drain

A horizontal branch drain is designed to convey wastewater from vertical stacks to the main drainage system, not specifically for connecting a single fixture. This option does not accurately reflect the specific purpose of Pipe A as defined by the Code.

Conclusion

The designation of Pipe A as a fixture branch is definitive because it specifically describes the role of connecting individual fixtures to the drainage system, complying with the Code's definitions. Other options, while related to waste and drainage systems, do not accurately convey the specific function of Pipe A, confirming that B is the most appropriate choice.
