Zusammenfassung:	PROBLEM TO BE SOLVED: To provide potable domestic water that prevents scale from being deposited on piping, a method for preventing scale deposition, and a hot water supply system.SOLUTION: This potable domestic water has a sulfate ion concentration adjusted within a range from 2,000 to 5,000 ppm, and pH of 6.5 to 7.8. The method for preventing scale deposition that allows circulation of potable domestic water having pH of 6.5 to 7.8 is configured to adjust the concentration of sulfate ion in the domestic water within a range from 2,000 to 5,000 ppm.
