Clean the Faucet Aerator — Inspect and Clean the Faucet Cartridge
Part of project
How to Fix Low Water Pressure in a Single Faucet · Step 3 of 4
In this video
Locate the aerator at the very end of the faucet spout. Unscrew it by hand or with pliers if it's tight. Be careful not to scratch the finish. Once removed, you may see visible debris. Tap the aerator on a hard surface to dislodge larger particles. Separate the screen from the housing and the rubber washer. Rinse all parts thoroughly under running water to remove any remaining sediment. Turn the faucet on for a moment without the aerator to flush out any debris in the spout itself. Reassemble the aerator and screw it back onto the faucet, hand-tightening it.
Goal: Remove and clean any debris from the faucet aerator.
- Briefly run the water with the aerator removed to flush out any loose debris from inside the faucet body.

FAQs
What are the essential tools and materials I'll need for this project to avoid unnecessary purchases?
You'll primarily need basic hand tools like an adjustable wrench, Phillips head and slotted screwdrivers, and tongue-and-groove pliers to disassemble the faucet. For cleaning, white vinegar, a soft scrub brush, rags, and a bucket are crucial. Don't worry about items like dining sets or shower drains listed; they are not required for this specific faucet repair.
Is it always necessary to shut off the main water supply to my house, or can I just use the shut-off valves under the sink?
For a single faucet repair, shutting off the water supply directly at the angle stop valves under the sink is usually sufficient. Only resort to shutting off the main water supply to the house if your under-sink valves are absent, faulty, or if you suspect a deeper issue that requires the entire water system to be off.
What should I do if cleaning the aerator doesn't improve the water pressure at all?
If cleaning the aerator doesn't help, the next step is to inspect and clean the faucet cartridge. Mineral buildup or debris in the cartridge is a common cause of low water pressure. Carefully remove the cartridge according to your faucet's specific instructions and soak it in vinegar to dissolve any mineral deposits.
After cleaning both the aerator and cartridge, my water pressure is still low. What could be the next culprit?
If the problem persists, you should check the hot and cold supply lines leading to the faucet. They might be kinked, corroded, or partially blocked by sediment. Disconnect them and flush them out into a bucket. If the problem affects multiple fixtures, it might indicate a whole-house issue.
