A dictionary defines water as a "compound of oxygen and hydrogen. he molecular formula is H2O Pure water is free of color, taste, or smell and in a liquid state at room temperature, boils at 99.974°C under one bar, has its maximum concentration at 4°C, and freezes at 0°C."This is the definition of pure water, somewhat different from the water we drink every day.

Your requirements are based on the level of risk for your property. See below a general backflow requirements guide of risk level.
