How to Remove a Water Restrictor in a Faucet Nozzle

In an effort to conserve water, almost all faucet manufacturers have aerators with water restrictors. If you are getting low water pressure from your faucet, you should remove the water restrictor and clean the sediment that is around the tiny holes. The water restrictor is made up of a flat disc and a mixer. These restrictors reduce the amount of water that comes out of the faucet, thereby reducing water consumption. Removing a water restrictor will only take one tool and a few minutes.

Place a cloth around the aerator to protect the finish. Grip the cloth and the aerator with a pair of pliers.

Rotate the aerator counterclockwise with the pliers until you can unthread the aerator by hand. Unthread the aerator from the faucet and set it on the counter.

Remove the rubber washer that covers the water restrictor. Pull the flat water restrictor off the water mixer restrictor. The flow restrictor is the flat disc that has a hole in the middle with a circle of tiny holes surrounding the centre.

Pull the water mixer restrictor out of the aerator. The mixer is the piece that has many tiny holes all around.


You can remove the collar and screen and clean them as well when cleaning the restrictors. Use a solution of vinegar and water to clean restrictors and screens.


Reassemble the faucet aerator exactly as the aerator is taken apart. Failure to reassemble the aerator correctly could cause poor water pressure.
