How to Fix a Leaky Faucet
You can typically fix a leaky faucet by simply replacing the cartridge. This is a fairly simple fix that you can do yourself following these five steps.
Tools/Materials:Crescent wrench or channel locks, knife, Phillips screwdriver or an assortment of Allen wrenches.
Step by Step Instructions
Pop out the button that covers the screw.
Use your screwdriver or Allen wrench to loosen the screw. You'll need to remove the bonnet and handle to expose the inside.
The cartridge will be exposed, so look for the sediment or hard water, both of which can cause blockage.
Some cartridges have a nub that lines up with a slot on the faucet. Replace the cartridge.
Replace the retaining nut, but don’t overtighten. Also replace the bonnet, faucet handle, screw, and button.
