   Faucets that meet energy efficiency standards for WaterSense mustn’t use more than 1.5 gpm, a 32% decrease in flow rate over the federal requirement. [10] Reduced flow faucets often make use of flow restrictors or faucet aerators to reduce the flowrate of the water. Using a faucet with an aerator results in an average 42% reduction in water ...
