Piping connections for a heating water, domestic hot water, and industrial hot water skid provided by the HVAC contractor. The domestic cold water line is sized at two inches and includes a pressure gauge, check valve, and a three-quarter-inch branch serving expansion tank ET-1 with the expansion tank set to cold water pressure. The hot water supply line is two inches at one hundred twenty degrees Fahrenheit with a recirculation pump designated RP-1, three-quarter-inch hot water return line, and a one-and-one-quarter-inch hot water line. A similar arrangement serves the industrial hot water loop with expansion tank ET-2, recirculation pump RP-2, three-quarter-inch industrial hot water return, and one-and-one-quarter-inch industrial cold water line. Each recirculation pump is powered by a one-hundred-fifteen-volt alternating current switched circuit. All pipes connect to the skid utilizing typical connection points.
