Maintenance Tips: Changing The Sink Aerator

It is sometimes necessary to change out the sink aerator in the kitchen or bathroom to ensure a steady water flow and avoid unwanted leaking or splashing. It can also save water use. For DIY enthusiasts, this is a great place to get your hands wet with plumbing know-how.

Aerator basics

According to eHow, aerators reduce the water coming through the faucets by mixing it with air. This means the “aerator acts as a sieve, sending a separating a single flow of water into many tiny streams. This introduces the air into the water flow.”

Aerators are inexpensive and come in varying designs that control the flow. eHow estimates aerators can save up to 280 gallons a month.

The aerator you choose can reduce your faucet flow to 2.5 gallons per minutes down to 0.5 gallons per minute (GPM). While the 0.5 GPM will save more money, it will also take you a long time to fill up a sink.

WaterSense for water efficiency and performance

wspromolabel_lookOne of the best ways to reduce water use in the bathroom is to install faucet aerators that have earned the WaterSense label, ensuring water efficiency and performance. WaterSense labeled bathroom sink faucets and accessories using a maximum of 1.5 gallons per minute can reduce a sink’s water flow by 30% or more from the standard flow of 2.2 gallons per minute without sacrificing performance.

According to the EPA, replacing old, inefficient faucets and aerators with WaterSense labeled models can save the average family 700 gallons of water per year, equal to the amount of water needed to take 40 showers. Also, since these water savings reduce demands on water heaters, households will also save enough energy to run a hairdryer 10 minutes a day for a year. Achieving these savings can be as easy as twisting on a WaterSense labeled aerator, which can cost as little as a few dollars.
