PROBLEM TO BE SOLVED: To provide a siphon drain construction method for a siphon drain system, especially reducing drain noise due to entrainment of air from the trap side in saving and releasing drainage, and preventing occurrence of sealing water shortage. SOLUTION: In this siphon drain construction method, a drain pipe from a plumbing device expected to discharge a large quantity of drainage at one time such as a kitchen and two horizontal pipes are connected to each other. In the method, a connector is formed of a cylindrical base connected to the drain pipe and two small-diameter pipe bodies extended from the pipe, and a siphon breaker is installed on the pipe body passage side not used in continuous draining. In the drawings, the reference numeral 1 designates a cylindrical base, 2 and 3 designate small-diameter pipe bodies, 4 and 5 designate horizontal pulling pipes, 6 designates a floor slab, 7 designates a drain pipe from the kitchen or the like, and 30 designates the siphon breaker.
