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.

Shop Wrenches and Shop Screwdrivers

Step by Step Instructions

Step 1:

Pop out the button that covers the screw.

Step 2:

Use your screwdriver or Allen wrench to loosen the screw. You'll need to remove the bonnet and handle to expose the inside.

Step 3:

The cartridge will be exposed, so look for the sediment or hard water, both of which can cause blockage.

Step 4:

Some cartridges have a nub that lines up with a slot on the faucet. Replace the cartridge.

Step 5:

Replace the retaining nut, but don’t overtighten. Also replace the bonnet, faucet handle, screw, and button.
