An aerator is an inconspicuous small faucet attachment that is installed at the end of the faucet and performs several valuable functions. Not all faucets have one. If you are unsure of your faucet, be aware of the water flow from the faucet nozzle when you turn it on. Usually it's common in basin faucet. If water flows in a steady, controlled stream filled with bubbles, it may pass through an aerator, but if it spills over a cliff like a mountain stream (or sprays out like a miniature fire hose), then there may be no aerator.

The aerator ensures that all water flows into your cup or anywhere you point to the faucet and that no water is wasted by spraying it onto the sides of the tank or the rear baffle. It also limits water flow and thus helps to protect this valuable resource. An aerator can do this because it contains a fine screen that separates water into hundreds of tiny streams, increasing its exposure to the atmosphere and oxidizing it, which is why it is called an aerator.

The most common problem with aerators is that they collect mineral deposits (scale) and block them, thereby reducing the flow of faucets and interfering with water flow. Many people mistake blocked ventilators for faucets or water pipes and spend money on plumbers when all they need is a pair of pliers and a bowl of vinegar to restore water flow easily. When the water flow from the faucet is less than it should be, you should first check the aerator.

The aerator is screwed to the tap nozzle. It can have either male or female threads, depending on the tap. Long-nosed kitchen faucets usually have external threaded faucets water tap, so the breather fitted on the faucets has internal threads. Bathroom faucets, especially those designed by designers, are more likely to have male and female threads to accept ventilators with male threads.

Either way, it can be removed by unscrewing the aerator. When you do this, you will be able to divide it into several components, which typically include the following:

Housing. This is a metal or plastic housing in which all other parts are mounted. It is part of the aerator and is screwed to the tap.

Inner shell, usually plastic. It slides into the housing.

Screen mounted on the ridge of the housing. This is the main working part of the aerator and the part collecting scale.

Strainer bushing. The plastic part is mounted in the opening of the housing and holds the screen in place.

Washing machine. This rubber ring is located on the top of the bushing and will be sealed on the faucet nozzle when you screw on the aerator and tighten it. Besides, like bathroom shower head, there is no aerator in it.

In addition, many aerators contain two additional components. One is a mixer, which is a disc with several holes to buffer the water flow without damaging the filter screen. The other is a current limiter, which is a single disc with a hole to reduce water flow. Some states, such as California, require flow restrictors.
