An electric water cooler plumbing connection requires a one-half inch domestic cold water supply line equipped with a shut-off valve, union, and water hammer arrestor. The waste piping consists of a one-and-one-half-inch waste line connected through a trap, paired with a one-and-one-half-inch vent line tying into the building drainage system. Both free-standing and wall-mounted configurations are detailed showing the exact arrangement of valves, fittings, and fixture connections against the wall.
