NIST 1772 (7788038864) - A room filled with lots of pipes and wires

The manifold system that is used to distribute hot and cold water to fixtures within the facility. The blue tubing supplies the cold water and the insulated lines on the left supply hot water to each fixture. A manual valve on each supply line allows the water supply to be easily shut off to each individual fixture without affecting the operation of the other water fixtures within the house. The heat pump water heater is shown in the left of the picture.
