Two days later the supply chain architect was in awe of the copper artwork nested within the framing by George, the plumber. The kitchen had been an empty shell of a room just hours before. Now it sparkled with hand-wiped solder joints where the copper pipes merged and an occasional piece of shiny black plastic PVC piping. The center island would hold the main sink with a garbage disposal unit. A second sink would be in the countertop along the back wall. The dishwasher would be built into the center island, and the refrigerator required a plumbing hookup for its automatic icemaker. The exposed studs showed additional plumbing runs to the upstairs bath and to a powder room adjacent to the kitchen.
