The aerator is a small screen located at the end of your faucet. Its purpose is to mix air with the water to create a steady stream. Over time, sediment and debris can build up in the aerator, causing a blockage and reducing water pressure. To fix this, unscrew the aerator from the faucet and clean it thoroughly with a mixture of vinegar and water. If the aerator is damaged, it may need to be replaced.Clogged Aerator
If the aerator is not the issue, the problem may be with your faucet itself. Over time, the internal parts of a faucet can wear out, causing leaks and reduced water pressure. If you notice any leaks or damage to your faucet, it may be time to replace it.Faulty Faucet
