Fix a leaky faucet in minutes with this easy-to-follow guide. Learn how to identify the issue and fix common faucet leaks yourself.
Stop wasting water and money by fixing a leaky faucet yourself with these simple steps.
A leaky faucet can be an annoying and wasteful problem, but it’s usually an easy fix with the right tools and techniques. Whether it’s a dripping tap or a slow leak, you can resolve the issue quickly and efficiently. This guide walks you through the steps to identify the cause of a leaky faucet and how to fix it yourself—saving you time and money on professional repairs.
Step 1: Turn Off the Water Supply
Before starting the repair, ensure you shut off the water supply to the faucet.
- Locate the Shutoff Valves: The water supply valves are typically located under the sink. Turn both the hot and cold valves clockwise to shut off the water.
- Turn On the Faucet: Turn the faucet handle to relieve any remaining pressure and drain any water in the pipes.
Step 2: Identify the Type of Faucet
Different faucets require different repair methods. Common types include:
- Compression Faucet: Has two handles (one for hot, one for cold).
- Ball Faucet: Often used in kitchens, these have a single handle.
- Cartridge Faucet: A single-handle faucet commonly found in bathrooms.
- Ceramic Disk Faucet: Uses a ceramic disk to control the flow of water.
Understanding which type of faucet you have will help you know what parts you need and the method for repairing it.
Step 3: Gather the Necessary Tools
You’ll need a few basic tools to get the job done:
- Adjustable Wrench
- Screwdriver (Flathead and Phillips)
- Plumber’s Tape
- Replacement Parts (like washers, O-rings, or cartridges)
- Faucet Repair Kit (if applicable for your type of faucet)
Step 4: Disassemble the Faucet
Once you have the right tools, it’s time to disassemble the faucet.
- Remove the Handle: Use a screwdriver to remove the handle. If there’s a decorative cap, pry it off first to reveal the screw.
- Remove the Retaining Nut: For compression faucets, remove the nut holding the valve stem in place with an adjustable wrench. For ball, cartridge, or ceramic disk faucets, you may need to remove a special nut or collar that holds the internal parts.
- Take Out the Valve or Cartridge: Carefully pull out the valve stem (for compression faucets) or the cartridge (for other types).
Step 5: Inspect the Parts for Wear
Look closely at the parts you’ve removed for any visible signs of wear or damage.
- Washers: Check if the rubber washers are cracked or worn out. These are common causes of leaks, especially in compression faucets.
- O-rings: Inspect O-rings for wear or damage. These are usually found on cartridge or ball faucets.
- Cartridge or Valve Stem: For cartridge or ball faucets, the cartridge may need to be replaced if it’s faulty. Check for cracks or wear.
- Clean Parts: If the parts are not too worn, you can clean them with a cloth to remove any debris or mineral buildup.
Step 6: Replace the Damaged Parts
Once you’ve identified the damaged parts, replace them with new ones.
- Washers/O-rings: Replace old washers or O-rings with new ones of the same size. Make sure they fit properly into their grooves.
- Cartridge/Valve Stem: If the cartridge or valve stem is damaged, replace it with a new one. Ensure the replacement matches the exact model of your faucet.
- Lubricate: Apply a thin layer of plumber’s grease to the O-rings or moving parts to make reassembly easier.
Step 7: Reassemble the Faucet
Once the new parts are in place, carefully reassemble the faucet.
- Insert the New Cartridge or Valve Stem: Slide the new cartridge or valve stem back into place.
- Tighten the Retaining Nut: Use the adjustable wrench to securely tighten the nut that holds the valve or cartridge in place. Be careful not to overtighten.
- Reattach the Handle: Place the handle back onto the faucet and screw it into place.
Step 8: Turn On the Water Supply
Once the faucet is reassembled, turn the water supply back on.
- Turn on the Faucet: Gradually turn on the hot and cold water supplies and test the faucet for leaks.
- Check for Drips: If the faucet still leaks, check that all the parts are correctly installed and that they are tightly secured. If the problem persists, you may need to inspect the faucet further or replace additional parts.
Step 9: Test the Repair
Finally, test the faucet again to ensure the leak is gone.
- Check for Leaks: Run both hot and cold water for a few minutes to ensure the leak has stopped.
- Check for Drips: If the faucet no longer drips or leaks, the repair is complete. If there is still a problem, inspect the new parts again or consider calling a professional.
Bonus Tips for Faucet Maintenance
- Prevent Future Leaks: Regularly clean the faucet’s aerator to prevent mineral buildup.
- Use the Right Tools: Always use the correct size tools to avoid damaging parts.
- Replace Parts Promptly: Don’t wait too long to replace worn parts; this can help prevent further damage.
- Water Pressure: Check the water pressure in your home. High pressure can sometimes cause leaks, and a pressure regulator may be needed.
Conclusion
Fixing a leaky faucet is a simple DIY task that can save you money on your water bill and avoid further damage. By following the steps in this guide, you can quickly identify and replace the worn parts causing the leak.
