Most of us know we can save water if we turn off the tap while brushing our teeth (as much as 3,000 gallons per year!), but did you know that there are products that will help save water when you turn on the tap too? WaterSense labeled faucets and faucet accessories (such as aerators) are high–performing, water–efficient fixtures that will help you reduce water use in your home and save money on water bills. By retrofitting your entire bathroom with WaterSense labeled fixtures, you can save even more. WaterSense labeled bathroom sink faucets and accessories that use a maximum of 1.5 gallons per minute can reduce a sink's water flow by 30 percent or more from the standard flow of 2.2 gallons per minute without sacrificing performance. We could save billions of gallons nationwide each year by retrofitting bathroom sink faucets with models that have earned the WaterSense label. All products bearing the WaterSense label complete an independent certification process to ensure they meet EPA criteria.

Faucets and faucet accessories—products that can be attached easily to existing faucets to save water—that obtain the WaterSense label have demonstrated both water efficiency and the ability to provide ample flow. 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. If every home in the United States replaced existing faucets and aerators with WaterSense labeled models, we could save nearly $1.2 billion in water and energy costs and 64 billion gallons of water across the country annually - equivalent to the annual household water needs of more than 680,000 American homes. Whether replacing an older, inefficient faucet that's wasting water and money, or simply looking for options to reduce water use in your home, choose a WaterSense labeled bathroom sink faucet or aerator. WaterSense labeled models are available at a wide variety of price points and a broad range of styles and in many areas, utilities offer rebates and vouchers that can lower the price even further.

The next time you wash your hands or brush your teeth, you'll know that you're doing your part to help protect our precious water resources.

A faucet aerator (or tap aerator) is often found at the tip of modern indoor water faucets. Aerators can be simply screwed onto the faucet head, creating a no-splashing stream and often delivering a mixture of water and air. An aerator serves the following purposes: When a single stream of water hits a surface the water must go somewhere, and because the stream is uniform the water will tend to go mostly in the same direction. If a single stream hits a surface which is curved, then the stream will conform to the shape and be easily redirected with the force of the volume of water falling.

Adding the aerator does two things; reduces the volume of falling water which reduces the splash distance, and creates multiple "mini-streams" within the main stream. Each mini-stream, if it were falling by itself would splash or flow in a unique and different way when it hit the surface, as compared to the other mini-streams. Because they are all falling at the same time, the streams will splash in their own way but end up hitting other splash streams.

In the case of hot water, because less water is used, less heat energy is used. The perception of water pressure is actually the speed of the water as it hits a surface, (the hands, in the case of hand washing). When an aerator is added to the faucet (or fluid stream), there is a region of high pressure created behind the aerator. Because of the higher pressure behind the aerator and the low pressure in front of it (outside the faucet), due to Bernoulli's Principle there is an increase in velocity of the fluid flow. Aeration occurs in two basic steps:[2][1] Three major components of an aerator are: housing, insert and rubber washer. A faucet aerator can be classified on the basis of its flow rate and the type of water stream (aerated, non-aerated, spray) it produces. In general, standard-sized aerators are available with female (M22x1) or male threading (M24x1). Bathtub spouts often have a bigger diameter with a male M28x1 thread. The United States use different thread sizes: 15/16"-27 for standard-sized male and 55/64"-27 for standard-sized female threads.

Using faucet aerators may help meet local regulations and construction standards such as ASME A112.18.1, U.S. Leadership in Energy and Environmental Design (LEED) certifications[3][] or WELS (Australia/New Zealand). In Europe, European standard EN246 "Sanitary tapware - General specifications for flow rate regulators" defines the flow rate and noise reduction requirements. ^ a b A US patent 4789103 A, Gottfried Ruhnke, "Faucet aerator" ^ A US patent 2541854 A, "Water aerating device" ^ LEED for Homes Rating SystemI Cannot Remove the Aerator From My Kohler Faucet If your Kohler faucet aerator is stuck and will not come off, there are a few tricks and techniques to employ before giving up. Removing and replacing the aerator is a smart idea if debris is caught in the aerator or you want to install an on-the-faucet filter. Due to Kohler's unusual aerator design, this chore is harder than it is on other faucets. Attempt to remove the aerator on your Kohler faucet with your hands.

If this does not work, use a rag or another item like a towel to provide more grip to your aerator. Since the aerator on Kohler chrome faucets has a shiny metal exterior, gripping it is difficult. Once additional grip is in place, twist in a counter-clockwise motion with short, hard jerks. This frees the aerator of built-up sediment and eventually loosens it. Grip down toward the end of the aerator, since Kohler spouts overlap the aerators. This provides maximum leverage on the aerator and not the spout itself. If using a towel or cloth to grip the aerator does not work, employ the use of vice grip pliers, or regular, adjustable pliers, often called plumber's pliers. These pliers provide an adjustable gripping device with an extension arm to provide leverage. The additional grip and leverage of these devices makes easy work of most Kohler aerators. To avoid scratching the surface of the aerator, wrap electrical tape around the pliers. This prevents damaging scratching to the aerator and spout, since Kohler aerators are mounted at an angle with part of the spout overlapping the edge.

If pliers do not work for your aerator, use a sediment dissolving cleaner to loosen the aerator. A cleaner designed to remove lime scale, rust and mineral deposits is useful here. Spray the cleaner around the aerator, near the base of the spout, so it soaks into the threaded portion of the aerator. Allow several minutes for the cleaner to work. Wipe the cleaner off the aerator and try loosening it with your pliers once again. Leverage is important on a Kohler aerator. Remember that the aerator is set at a slight angle to the base of the faucet and the spout. It is, therefore, important to twist the aerator in a rotation parallel to this angle. Otherwise, the aerator will not come off. This is true when using your hands or pliers. Angle the rotation of the pliers by lifting the handle up and pushing the clamp section down while the pliers are facing toward the faucet. Kohler aerators angle downward into the sink basin toward the back of the faucet. Creative Homeowner: Projects Online: Cleaning a Faucet Aerator
