Specific gravity in plumbing refers to the ratio of the weight of a specific volume of liquid compared to the weight of the same volume of water at a given temperature. It is an important parameter for understanding the density of fluids used in plumbing systems, such as wastewater, fuel, or antifreeze solutions. Specific gravity helps determine flow rates, pressure requirements, and compatibility with pumps and other components. Accurate measurement of specific gravity ensures efficient system design, prevents equipment damage, and maintains safety in plumbing systems that handle fluids other than water.
