Rough-in plumbing - supply & waste lines, w/PEX - Branched

This line item refers to rough-in plumbing that utilizes PEX (cross-linked polyethylene) tubing for the supply and waste lines in a branched configuration. PEX is a flexible, durable material that is increasingly used in modern plumbing due to its ease of installation and resistance to corrosion. A branched system involves running separate lines from a central manifold to each fixture, allowing for more precise control and efficient water distribution. This setup is particularly beneficial for reducing pressure drops and ensuring consistent water flow throughout the building.
