A leaky faucet can be annoying and waste water, but the good news is that fixing it is usually an easy and inexpensive DIY project. Follow these steps to fix a leaky faucet and save yourself from paying for professional repairs.

Materials Needed

• Adjustable wrench
• Screwdriver (flathead and Phillips)
• Replacement parts (e.g., washers, O-rings, or cartridge, depending on faucet type)
• Plumber’s tape (optional)
• Cloth or rag
• Silicone grease (optional)

Step 1: Turn Off the Water Supply

1. Locate the Shut-Off Valves: Underneath your sink, find the two shut-off valves (one for hot water and one for cold water).
2. Turn Off the Water: Turn both valves clockwise to shut off the water supply to the faucet. If you can’t find the valves under the sink, turn off the main water supply to your home.
3. Open the Faucet: Turn the faucet handle to release any remaining water in the pipes. This will prevent water from spilling out when you disassemble the faucet.

Step 2: Remove the Handle and Trim

1. Locate the Set Screw: The faucet handle is usually held in place by a set screw, which may be hidden under a decorative cap.
2. Remove the Handle: Use a flathead screwdriver to pry off the decorative cap (if applicable). Then, use a screwdriver to remove the set screw and take off the handle.
3. Remove the Trim (If Applicable): Some faucets have additional decorative trim pieces that may need to be removed. Use a wrench or screwdriver to remove these pieces carefully.

Step 3: Identify the Problem

1. Determine Faucet Type: Faucets generally fall into one of three types: compression, ball, cartridge, or ceramic disk. Identifying the type will help you understand which parts need to be replaced.
2. Inspect for Wear: Check the rubber washers, O-rings, and other parts for signs of wear or damage. A worn washer or O-ring is the most common cause of leaks.
3. Take the Parts to the Store: If you’re not sure which part to replace, take the old washer, O-ring, or cartridge to the hardware store to get an exact match.

Step 4: Replace the Damaged Parts

1. Compression Faucets:

   • Remove the valve stem by unscrewing it with an adjustable wrench.
   • Replace the rubber washer at the end of the valve stem with a new one.
   • If the O-ring is worn, replace it as well.

2. Cartridge Faucets:

   • Remove the retaining nut holding the cartridge in place.
   • Pull out the old cartridge and replace it with a new one.
   • Make sure the cartridge is inserted in the correct direction.

3. Ball Faucets:

   • These faucets are a bit more complex. If the leak is coming from a ball faucet, it’s best to replace the entire faucet cartridge.
   • Remove the faucet handle and the ball assembly. Replace the worn-out parts, such as springs, rubber seals, or O-rings.

4. Ceramic Disk Faucets:

   • Remove the handle and the decorative cap.
   • Take out the ceramic disk valve and inspect for cracks or mineral buildup.
   • Clean the valve and replace any damaged parts.

Step 5: Reassemble the Faucet

1. Reinstall the Parts: Once the damaged parts are replaced, reassemble the faucet in reverse order.
2. Tighten the Components: Be sure that all parts are tightened securely but not overly tight, as this can cause damage.

Step 6: Turn the Water Back On

1. Turn On the Shut-Off Valves: Slowly turn the water supply valves back on.
2. Check for Leaks: Turn on the faucet and check for any leaks around the newly installed parts.
3. Test the Faucet: Run both hot and cold water to ensure the faucet is functioning properly and there is no longer any leakage.

Pro Tips

• Use Plumber’s Tape: If you have trouble with fittings that don’t tighten properly, use plumber’s tape to seal the threads.
• Clean the Faucet: While you have the faucet disassembled, clean any mineral buildup or debris from the faucet components using a vinegar solution.
• Take Your Time: Be patient when handling small parts, and don’t rush the installation process to avoid mistakes.

When to Call a Professional

If you’ve replaced the washers, O-rings, or cartridges and the faucet is still leaking, the valve seat or faucet body may be worn out, requiring professional repair or replacement. In such cases, it’s best to call a plumber for assistance.

With these easy steps, you’ll be able to fix a leaky faucet and prevent water wastage. Enjoy a fully functional faucet without the need for a costly repair!
