We all know how frustrating a leaky faucet can be. Most of the time, the cartridge of your faucet causes this issue. Fortunately, the expert plumbers here at Service Pros Plumbers can help you stop that incessant drip, drip! Just follow these easy steps:

Tools You’ll Need:

Hex key or Allen Wrench
Crescent wrench
Faucet lube or Grease
A new cartridge (We’ll teach you how to identify your cartridge and get a replacement in the instructions!)

Instructions

Shut the water off. Be sure to verify that it’s off by testing the hot and cold water from your faucet.
Take your Allen wrench, loosen the set screw on the handle, then pull the handle off.
Remove the bonnet nut by loosening it with the crescent wrench. This will give you access to the cartridge.
Remove your cartridge, and replace it with a new one. If you have never replaced your cartridge before, that’s ok. Here’s what our team at Service Pros Plumbers does: take a picture of the cartridge and the faucet and head to the hardware store. They will be able to get the correct cartridge to you for installation. Unfortunately, if your faucet has a leaking cartridge, the most common fix is simply replacing it with a new one rather than repairing the cartridge itself.
Put a bit of faucet lube on the new cartridge and the bonnet nut.
Carefully align the new cartridge and replace it. Most cartridges have bumps that must be lined up correctly with the faucet. You should be able to feel these click-in. Check out our video above for an easy visual guide to this step.
Put the bonnet back on and tighten it.

This is an excellent point to test that the water is coming out correctly. Turn the water back on and try both the hot and cold.
Replace the handle and then tighten.
