Flow fixtures are devices that measure the rate of water flow in a plumbing or fixtures system, focusing primarily on how much water is delivered over a specific period. The most common measurement unit for flow fixtures is Gallons per Minute (gpm), which indicates the volume of water flowing through the fixture every minute. This is particularly important for assessing water efficiency in fixtures like faucets, showerheads, and toilets, as it allows for standardized comparisons and evaluations of water usage.

While liters per second, gallons per hour, and liters per week are also potential ways to express water flow or usage, they are not the standard measure typically associated with flow fixtures in the context of plumbing and water efficiency assessments. Gallons per minute provides a clear and direct understanding of immediate water consumption, which is crucial for both designing water-efficient systems and for regulatory compliance in LEED certifications.
