Three curved sections of copper pipe connect the spokes. These were made by bending 1/2-inch diameter copper plumbing pipe into 1.5-foot, 3-foot, and 4.5-foot radius 160-degree segments. Seven stepped holes were drilled through each pipe section to attach them to the spokes. Sheet metal screws attach the copper arcs to the EMT spokes. One side of each pipe was double gold leafed.
Structured PEX Plumbing systems make use of the recirculation of hot water. Manifolds in this system will be located near groups of fixtures. For the hot water lines, open ended manifolds are used. By doing this, the hot water return line is created as an extension of the hot water supply line. This system's main benefit is a reduction in the usage of water and energy due to the on demand recirculation.
