Shut Off Water Supply
Locate the water valves under the sink. These control hot and cold water flow. Turn both valves clockwise to close them. This stops water from reaching the faucet.
Check if the water is off by turning on the faucet. No water should come out. If water still flows, look for the main water shut-off in the house. Turn it off to stop water completely.
Place a bucket or towel under the pipes. This catches any water left in the lines. It helps keep the area dry while fixing the faucet.
Remove Faucet Handle
First, locate the set screwon the faucet handle. It is usually hidden under a small cap or on the side of the handle. Use a flathead screwdriver or an Allen wrench to remove the screw carefully. This screw holds the handle tightly in place.
Once the set screw is removed, lift the handle offthe faucet. Sometimes the handle may be stuck due to mineral buildup. Gently wiggle it up and down while pulling upwards. Avoid using too much force to prevent damage.
If the handle does not come off easily, applying a little bit of lubricantaround the base can help loosen it.

Cleaning the cartridge can fix many faucet problems. Use a soft brush and vinegarto remove mineral buildup. Avoid harsh chemicals that may harm the cartridge material.
