Manifold
A manifold is a central plumbing component that connects multiple pipes into one system, like a hub or distribution center for water, gas, or other fluids. Think of it like a traffic controller that directs water or gas to different parts of a building. It's commonly used in modern plumbing systems to efficiently manage water flow to different areas, such as bathroom fixtures, heating systems, or industrial equipment. When plumbers mention manifolds, they're usually talking about these distribution systems that help organize and control the flow of water or gas throughout a building.

Example Interview Questions
Senior Level Questions
Q: How would you design a manifold system for a large commercial building?
Expected Answer: A senior plumber should explain the planning process, considering factors like water pressure, number of outlets needed, and system maintenance access. They should mention calculations for proper sizing and pressure requirements.
Q: What considerations do you take into account when troubleshooting a problematic manifold system?
Expected Answer: Should discuss systematic approach to identifying issues like pressure problems, leaks, or balance issues, and explain how to test each branch of the system efficiently.
Mid Level Questions
Q: What are the different types of manifolds and their applications?
Expected Answer: Should be able to explain common types like copper, brass, and plastic manifolds, and when each is most appropriate to use in different plumbing scenarios.
Q: How do you ensure proper pressure balance in a manifold system?
Expected Answer: Should explain basic pressure testing procedures, using pressure gauges, and how to adjust flow rates for different branches of the system.
Junior Level Questions
Q: What is a manifold and what is its basic function in plumbing?
Expected Answer: Should be able to explain that a manifold is a central distribution point that takes one main water line and splits it into multiple lines for different fixtures or areas.
Q: What are the basic safety considerations when working with manifolds?
Expected Answer: Should discuss proper shutdown procedures, pressure release methods, and basic safety equipment needed when working on manifold systems.
