What Does a Faucet Aerator Do


Clean water is sent to your home under constant pressure to ensure it makes its way throughout the community ending at your tap which normally contains a faucet aerator that performs a few different important functions that you never realized. What does a faucet aerator do?

Aerators:

  • Add air to H2O for the feeling of high-pressure
  • Control the stream from the faucet
  • Act as a filter to catch sand & debris that accumulates in H2O lines
  • Prevent splashing
  • Shape the H2O stream coming out of the faucet
  • Prevents noise
  • Conserve the amount of overall H2O usage
  • Reduce energy consumption

A Faucet aerator is normally a simple, mesh screen made of metal or plastic that is attached to the end of a faucet with some sort of housing. As water flows through this screen it is divided into many small streams with air in between. This little guy has a big job lowering water consumption, and utility bills and over the long term saving the environment.

What is a Faucet Aerator

A faucet aerator is a small, often cylindrical device attached to the tip of indoor water faucets. Its primary function is to mix air into the water stream, which helps reduce water usage while maintaining the feeling of a high-pressure flow.

By breaking the water into finer droplets, an aerator creates a more consistent and splash-free stream, enhancing the efficiency and comfort of water use in kitchens and bathrooms. Aerators typically consist of a mesh screen that divides the flow of water into multiple small streams, adding air and thus reducing the volume of water coming out without decreasing pressure. This not only conserves water but also aids in reducing energy costs, as less hot water is required.

Faucet aerators come in various sizes and flow rates, allowing users to choose one that best suits their needs. For instance, aerators with lower flow rates are ideal for sinks where conservation is a priority, while higher flow rates might be preferred in scenarios requiring faster filling of containers. Installation and maintenance of aerators are straightforward, often requiring minimal tools, making them a practical solution for households aiming to enhance water efficiency. They also serve as a simple yet effective measure to reduce water bills and support environmental sustainability.

Moreover, aerators can help in filtering out debris and contaminants, improving the overall quality of the water. They can also be customized to fit different types of faucets and to achieve desired water pressures and spray patterns. Over time, however, aerators can become clogged with mineral deposits, necessitating periodic cleaning or replacement to maintain optimal performance. Despite this, their benefits in terms of water conservation, cost savings, and user comfort make them a valuable addition to any home plumbing system.

In essence, a faucet aerator is a small but mighty component that significantly contributes to efficient water usage. Its ability to deliver a steady, aerated stream of water while conserving resources highlights its importance in modern water management practices. For environmentally-conscious individuals and those looking to reduce household expenses, installing faucet aerators is a simple and impactful step toward achieving these goals.

Faucet aerators are screens that screw into the kitchen and bathroom faucets that contain holes in the screens which add air to the water as it streams out of the faucet. Besides adding air to the water and leaving the faucet their job more importantly these aerators:

  • Reduce the amount of water that comes out of a faucet and control the stream.
  • They can catch particles that can make it through your supplier’s service lines. A faucet aerator screen can act as a filter and catch sand and debris that is produced over time or after your water supplier performs hydrant flushing during the year.
  • Prevent splashing
  • Shape the water stream coming out of the faucet spout, to produce a straight and evenly pressured stream regulating the flow
  • Prevent noise
  • Saving water then equates to energy cost reduction

The Environmental Protection Agency (EPA) has developed a program that identifies a water-efficient product that has been independently certified to meet EPA WaterSense criteria for efficiency and performance.

The EPA says that certain recommended faucets and aerators can meet their criteria to reduce the water demand. A little job like switching from an aerator that releases 2.2 gallons per minute to one that releases 1.5 gallons per minute can reduce water use by 30% without reducing performance. wspartner.png

 The organization will certifiy the product identified by the label if it meets the criteria. These products include faucets and faucet aerators that can meet these specifications that the government agency determines will cut costs of water consumption over periods of time, reduceing the demands on households. Achieving these savings can be as easy as twisting on a WaterSense labeled aerator, which can cost as little as a few dollars. When buying one look for this label!

How to Remove Faucet Aerator

FAUCET AERATOR

Some Delta faucets come with recessed aerators, which are hidden and can’t be removed using a wrench. If you don’t have the specific Delta key, you might be able to get a universal key from a hardware store or get a good bite using your fingers it’s most likely it’s only hand tight anyway. If that is not possible use a pair of needle-nose pliers to remove the hidden piece.

Moen faucet aerators have ridges built into them so you can turn them. If you can’t unscrew the piece with your fingers, you might be able to get a better grip with your fingernails or use a butter knife or flathead screwdriver. To remove-Turn the aerator counterclockwise.

On a standard Aerator, try to turn by hand- if it won’t budge then use pliers to turn the outside of the housing protecting the piece with a washcloth. (the rubber washer will normally stick up in the faucet’s opening so you may have to dig it out) Some aerators have male threads others have female threads.

  • If your faucet has threads on the outside, it is male threaded – which means you need to buy a FEMALE threaded aerator to fit over it.
  • If your faucet has threads on the inside, it is female threaded and you’ll need a MALE threaded aerator

Look for the EPA Water Sense logo or seal on the packaging these products offer equivalent or superior performance while helping you protect the environment and potentially save on utility bills. Look for the WaterSense label on our water-efficient products.

Many aerators aren’t very difficult to remove and are normally hand-tightened. Recessed models can be a little more tricky than exterior models because there’s no way to remove them with a wrench or pliers.

If you can’t make it budge then use a hairdryer just run the hot air on the tip of the faucet aerator to warm it up-then turn it counterclockwise. When all else fails call a plumber if you can’t remove it but there is no reason to think you can’t it’s a simple chore.

Cleaning Faucet Aerator

Water pressure has decreased in your faucet, the aerator may be the problem. An aerator can get clogged with silt and debris or the buildup of minerals from the water.
