For Electric & Natural Gas Customers
An aerator is often found at the tip of an indoor water faucet or inside a shower head. Without an aerator, water usually flows out as one or many larger streams. An aerator spreads this stream into a finer spray pattern, which helps increase water pressure while reducing the amount of hot or cold water being used. Using less hot water will reduce the energy used by your natural gas or electric hot water heater. The amount of water passing through the aerator is measured by gallons per minute or (GPM). The lower the GPM, the more water the aerator will conserve.
