Aerators: Aerators are a small mesh screen that has air coming through that reduces splashing and controls the flow of water. Dirty aerators can cause low water pressure due to build up of sediments in bathroom sinks, showers, and kitchen sinks. The aerator can be cleaned by removing the screen on the front of the faucet or shower head. Aerators should be cleaned once every 6 months or so to keep the water pressure right. Aerators come in different sizes. You can use coins such as a dime or a nickle to tell the size of aerator you may need, simply by removing the insert and washer and placing a coin on top of the aerator. That will determine the size.
