Washington DC Plumbing Question: What is a Faucet Aerator?

A tap aerator or faucet aerator is located on the tip of water faucets which are used indoors such as kitchen and bathroom sink faucets.  Their purpose is to spread the water stream into a number of smaller streams, in essence adding air to the water stream.  This saves the amount of water which comes out of the tap at one time while also reducing the amount of backsplash which occurs when the faucet is turned on.

Utilizing faucet aerators can be one of the most inexpensive ways to save money on water consumption and save energy.

There are two main types of faucet aerators, some which use metal or plastic screens to separate the water, and some which do not use screens. One advantage to those without screens is that they eliminate problematic clogging which occurs on screen aerators due to sediment buildup.  There are also aerators with off-valves and swivel aerators which allow users to direct flow to wherever the water spray is needed.

There are three main flow-types seen today. The needle method creates a circular pattern of small, single streams of water with no water-flow in the very center.  The aerated method created a tubular flow with air mixed into the water, creating a single stream of bubbly water.  The laminar method has no air mixed in which makes for a single stream of water with no bubbles.

Many aerators are designed as more economical low-flow aerators which optimize the water flow while still providing optimal water-flow performance.  In kitchens these low-flow options decrease flow from 2.2 gallons per minute to 1.5 gpm or 1.0 gpm, saving anywhere from 32% to 54% of water-usage.  On bathroom faucets the water-flow is decreased from 2.2 gpm to 1.0 gpm or even 0.5 gpm saving from 77% to 84% of water usage.  When engineered properly, low-flow or economic aerators can provide increased perceived water pressure while in actuality helping to save water.

When purchasing new faucet aerators, ensure that you find the proper type (male or female) and the proper size (regular or small).  There are dual-thread options for those who do not know whether a male or female aerator is necessary.  Also, look at the tap aerator’s price in conjunction with how much savings it can provide in water usage annually and see how little must be spent on each faucet in order to save hundreds of dollars.
