Aerators are installed on plumbing fixtures to do which of the following?

Aerators are installed on plumbing fixtures to achieve water savings. A faucet aerator mixes air into the water stream, reducing the flow rate while maintaining acceptable user performance for handwashing and similar uses. In LEED Water Efficiency, reducing indoor potable water use is achieved by selecting efficient fixtures and fittings, such as low-flow lavatory faucets, showerheads, toilets, urinals, and flow restrictors. Aerators do not pinpoint leaks; leak detection is usually supported by metering, monitoring, inspections, or water management practices. Aerators also do not determine performance by themselves, although fixture flow rates are used in water calculations. Tracking consumption trends is the role of building-level or system-level water meters. Aerators are a simple and effective demand-reduction strategy.
