Replace Bathroom Sink Cartridge - A Step-by-Step Guide

Is your bathroom sink faucet dripping or leaking? If so, you will probably need to replace the sink cartridge. A sink cartridge is a small, cylindrical device that controls the flow of water from the faucet. It is located inside the faucet's handle.

Replacing a sink cartridge is a relatively easy and inexpensive repair that can be done by most do-it-yourselfers. Here are the steps on how to replace a bathroom sink cartridge:

Step 1: Gather Your Tools and Materials

Before you begin, you will need to gather the following tools and materials:

Phillips head screwdriver
Adjustable wrench
Pliers
Bucket
Rags
New sink cartridge

Step 2: Turn Off the Water Supply

The first step is to turn off the water supply to the sink. There is usually a stop valve located under the sink. Turn the valve clockwise to turn off the water.

Step 3: Remove the Faucet Handle

Once the water supply is turned off, you can remove the faucet handle. There is usually a small set screw on the back of the handle. Use the Phillips head screwdriver to remove the set screw. Once the set screw is removed, the handle can be pulled off.

Step 4: Remove the Cartridge Retaining Nut

Once the handle is removed, you will see the cartridge retaining nut. This nut is usually made of plastic or metal. Use the adjustable wrench to loosen the nut and remove it.

Step 5: Remove the Old Cartridge

Once the cartridge retaining nut is removed, you can remove the old cartridge. Use the pliers to grasp the cartridge and pull it out of the faucet body.

Step 6: Install the New Cartridge

Take the new cartridge and insert it into the faucet body. Make sure that the cartridge is properly seated.

Step 7: Replace the Cartridge Retaining Nut

Once the cartridge is installed, replace the cartridge retaining nut. Tighten the nut until it is snug.

Step 8: Reattach the Faucet Handle

Once the cartridge retaining nut is tightened, reattach the faucet handle. Replace the set screw and tighten it until it is snug.

Step 9: Turn On the Water Supply

Once the faucet handle is reattached, turn on the water supply. Check for leaks around the faucet. If there are any leaks, tighten the cartridge retaining nut or adjust the handle until the leak stops.

Conclusion

Replacing a bathroom sink cartridge is a relatively easy and inexpensive repair that can be done by most do-it-yourselfers. By following these steps, you can save yourself the cost of hiring a plumber.
