Clearing a Blocked Faucet Aerator

  • 01 of 07
    Steve Hallo

    All kitchen and bathroom fixtures are equipped with an aerator located on the end of the faucet. The aerator's purpose is to add air to the water flow. This keeps the flow from spraying at an angle or with too much force. All aerators also contain screens to catch sediment that may be in the water line.


    When the screen gets blocked with sediment or mineral build up, the water pressure from the faucet will become noticeably lower. The spray may also become erratic. Luckily, this is an ease fix....MORE However, if you notice a drop in water pressure in more than one fixture in your home then the problem is in the system.

    Removing the Aerator

    Steve Hallo

    Grip the aerator with your hand and turn it clockwise to loosen it. If it doesn't turn, use a pair of padded pliers or wrap a rag around the aerator and use a pair of channel locks. The rag will act as a buffer to prevent scratching the aerators finish.

    If you have calcium or mineral deposits, soak the pieces in warm vinegar. Microwaving it for 15-30 seconds will warm it enough, it doesn't have to be boiling hot.

    Put the Aerator Back Together

    Steve Hallo
    Reassemble the aerator. Before screwing it back in it isn't a bad idea to run the fixture a little bit. This will clear out any remaining sediment or deposits that may have become loose.
