What does fixture supply refer to?

Fixture supply refers specifically to the pipe that delivers water to a plumbing fixture from either a branch or a main supply line. This component is essential because it ensures that fixtures such as sinks, showers, or toilets receive the necessary water to function properly.

Understanding the role of fixture supply is crucial in plumbing design and installation, as it impacts water pressure and accessibility for maintenance. The sizing and installation of these lines must adhere to local plumbing codes to ensure efficiency and compliance with safety standards.

The other options relate to different aspects of plumbing systems: the pipe leading to the sewage system pertains to waste removal, the fitting connecting a fixture to drainage deals with how waste is expelled from a fixture, and the pipe removing waste from a fixture focuses on waste management rather than the supply of water.
