Following Plumbing Post & Beam

 Here we see the initial stages of the plumbing going in. The picture to the right shows round bundles which is the type of fresh water lines installed Arbor Custom Homes. This style of tubing is called PEX which is a high density polyethylene. This water system has many advantages over the old CPVC or even copper and galvanized. These materials are flexible and require fewer connection. Connections are typically where water lines will leak. Connections also weaken the lines and can create drops in pressure. The PEX connections do not require glues, so there is less toxicity in the water. The PEX material can also withstand freezing weather. I've been told the lines can freeze and expand without breaking. When it thaws out, it will contract back to its original condition without damaging its structural integrity.

You can see the different sizes of the supply lines weaving through the floor joists. The size depends on the source location.

Notice how the PEX bends nicely, eliminating 90 degree angles, un-needed connections and creating a smoother water flow. The freshwater lines are held up high against the floor trusses so that they will be kept tucked into the floor insulation that goes in later. The black pipes are for waste water.
