# Replacing Your Leaking Cartridge Faucet

One of the most common repairs in the home is having to replace a leaking cartridge faucet. Despite what many people think, it is not difficult to do a cartridge faucet repair yourself, saving you an expensive plumber’s bill. It does not require any specialized tools. This guide shows you the tools required, and the process to follow in order to replace a leaking cartridge faucet.

### What is a Cartridge Faucet?

The cartridge faucet regulates the water flow that comes out of the tap. It can also control the temperature of the water. If you have a leak in your cartridge faucet, it is usually caused by a small rubber ring wearing out or the faucet itself becoming worn.

### What Tools are Required to Replace a Leaking Cartridge Faucet?

There are only a few main tools that are required when replacing a leaking cartridge faucet. You will need a screwdriver, a utility knife, and a pair of needlepoint pliers. You will also require some water pump pliers and a new cartridge.

### Do You Need to Turn Off the Water Before Replacing a Leaking Cartridge Faucet?

You will definitely need to turn off the water supply before replacing a cartridge faucet. You can choose to either turn the water off under the sink or cut it off at the main water supply.

### How do You Repair a Leaking Cartridge Faucet?

The first step is to remove the handle of the faucet by unscrewing the screws on the handle. The plastic retaining nut is exposed; this needs removing using water pump pliers. The faucet spout is then removed by lifting it straight up. You will see the cartridge faucet with a rubber O-ring around it. If you have not already purchased a replacement cartridge faucet, take the old one with you to the hardware store. This way you can make sure you get the correct one. The O-ring must be removed before you are able to use the pliers to remove the cartridge faucet. Put the new cartridge faucet in place and place the O-ring on the faucet cylinder. You may need to coat the O-ring with grease before you can place it back on. Place the faucet spout back on, put the plastic retaining nut on, and replace the handle. Turn your water back on to check that the leaking has stopped.

Do not be afraid of trying to repair or replace a cartridge faucet yourself. As long as you remember to turn the water off at the mains, you do not need to worry about your kitchen becoming flooded. Make sure you get the correct cartridge faucet as the one you previously had. Otherwise, you may find that it does not fit correctly and you may still have a leak.
