PROBLEM TO BE SOLVED: To make water drained from a safety valve flow into a stool surface safely even when high water pressure is applied to the upstream side of the safety valve, and to prevent the trouble of a sanitary flushing device due to the splash and scatter of waterdrops and the stain of a floor/a wall or the like for a toilet. SOLUTION: Since a drain path 5k for the safety valve 5 installed to a water supply system 11 for supplying a heat exchanger 6 for the sanitary flushing device 1 with water from a branch cock 2b for water supply piping 2a is converged to an outflow opening 12a for a water supply source (a low tank) 12 and water is drained to a stool 15, the trouble of the sanitary flushing device 1 and the stain of a floor/a wall or the like for a toilet due to the splash and scatter of waterdrops can be prevented even when high water pressure is applied to the upstream side of the safety valve 5.
