Tools and Materials You Will Need:
- Adjustable wrench
- New mixer cartridge
- Plumber’s grease
- Rag or towel
Step 1: Prepare the Work Area
Before you begin, make sure to shut off the water supply to your faucet. Look under the sink for the water shut-off valve and turn it clockwise until it is fully closed. This will prevent any water from flowing while you work.
Step 2: Remove the Handle
Using an adjustable wrench, carefully loosen and remove the handle of your faucet. Set it aside in a safe place. If your handle has a decorative cap, gently pry it off with a flathead screwdriver before removing the handle.
Step 3: Remove the Cartridge Retaining Clip
Locate the cartridge retaining clip, which holds the cartridge in place. Using your fingers or a pair of pliers, gently pull the clip towards you to remove it. Be careful as the clip may be under tension and could pop out. Set the clip aside.
Step 4: Remove the Old Cartridge
Gently pull the old cartridge straight out of its housing. You may need to wiggle it slightly to loosen it. If it’s difficult to remove, you can use a cartridge puller tool for assistance. Once the old cartridge is out, inspect it for any damage or signs of wear.
Step 5: Install the New Cartridge
Apply a thin layer of plumber’s grease onto the O-rings of the new cartridge. This will help create a watertight seal. Insert the new cartridge into the housing, making sure it is aligned properly. Push it in firmly until it sits flush.
Step 6: Replace the Cartridge Retaining Clip
Take the cartridge retaining clip you removed earlier and slide it back into place over the new cartridge. Ensure that it locks securely into the housing to hold the cartridge in place.
Step 7: Reassemble the Handle
Carefully reattach the handle to the faucet stem, ensuring it aligns correctly. Tighten it with an adjustable wrench until it is snug, but be careful not to overtighten as it could damage the faucet.
Step 8: Turn on the Water and Test
Once everything is reassembled, turn on the water supply by rotating the shut-off valve counterclockwise. Check for any leaks around the faucet. If there are no leaks, congratulations! You have successfully changed the mixer cartridge in your faucet.
By following these easy steps, you can save money and address a leaky faucet caused by a faulty mixer cartridge. Remember to consult the manufacturer’s instructions for any specific details regarding your faucet model. Happy fixing!
