A PEX manifold diagram is a schematic representation of a PEX (Cross-Linked Polyethylene) plumbing system. This diagram serves as a roadmap, guiding the installation and understanding of the plumbing system.

PEX Manifold: This is the central hub of the system. It usually includes separate sections for hot and cold water. Each section has multiple ports where PEX tubing is connected.

PEX Tubing: These are lines extending from the manifold to various water outlets. They are represented as lines on the diagram, each leading to a specific fixture.

Water Source: This shows the point of entry for the water into the manifold. It’s typically represented as a line coming into the manifold from the edge of the diagram.

Fixtures: These are the end points of the PEX tubing – sinks, toilets, showers, etc. They are usually represented by symbols indicating their type.

Shutoff Valves: These are located at the manifold for each PEX tubing line. They allow for easy control and maintenance of individual lines without disrupting the entire system.

Labels: The diagram should have clear labels for each component and line, indicating their purpose and destination.
