How To Fix A Leaky Single Handle Bathtub Faucet: A Step-by-Step Guide

A leaky single-handle bathtub faucet can be a real nuisance. Not only does it waste water, but it can also cause damage to your bathroom fixtures and floors. If you're facing this problem, don't despair! With a few simple tools and a little know-how, you can fix the leak yourself. ### Tools and Materials You'll Need: - Adjustable wrench - Phillips head screwdriver - Flat head screwdriver - Pliers - Replacement cartridge (if necessary) - Plumber's putty (if necessary) - Teflon tape - Rags ### Step-by-Step Guide: #### 1. Turn Off the Water Supply: Before you start working on the faucet, you need to turn off the water supply to prevent flooding. There should be two shut-off valves under your sink, one for the hot water and one for the cold water. Turn both valves clockwise until they are completely closed. #### 2. Remove the Faucet Handle: Once the water supply is turned off, you can remove the faucet handle. On most single-handle faucets, there is a small set screw on the side of the handle. Use the Phillips head screwdriver to loosen the set screw and remove it. Once the set screw is removed, you can pull the handle off of the faucet. #### 3. Remove the Cartridge: With the handle removed, you will see the cartridge. The cartridge is a cylindrical-shaped component that controls the flow of water. To remove the cartridge, use the adjustable wrench to loosen the retaining nut that holds it in place. Once the retaining nut is loose, you can pull the cartridge out of the faucet body. #### 4. Inspect the Cartridge: Once you have removed the cartridge, inspect it carefully for any damage. Look for cracks, chips, or other signs of wear and tear. If the cartridge is damaged, it will need to be replaced. #### 5. Clean the Faucet Body: While the cartridge is out, take the opportunity to clean the faucet body. Use the rags and plumber's putty to remove any dirt, grime, or mineral deposits that have built up. This will help ensure that the new cartridge fits properly and functions correctly. #### 6. Apply Teflon Tape: Before installing the new cartridge or the old one if it's in good condition, wrap the threads of the cartridge with Teflon tape. This will help create a watertight seal and prevent leaks. #### 7. Install the New Cartridge (if necessary): If you are replacing the cartridge, insert the new cartridge into the faucet body. Hand-tighten the retaining nut until it is snug. Do not over-tighten the nut, as this could damage the cartridge. #### 8. Reinstall the Faucet Handle: Once the cartridge is installed, you can reinstall the faucet handle. Align the handle with the stem on the cartridge and push it into place. Tighten the set screw until it is snug. #### 9. Turn On the Water Supply: Once the faucet handle is reinstalled, turn on the water supply. Check for leaks around the faucet. If you see any leaks, tighten the retaining nut or the set screw until the leak stops. #### 10. Test the Faucet: Turn on the faucet and let it run for a few minutes. Check for leaks around the faucet and make sure that the water temperature and pressure are correct. If everything is working properly, you have successfully fixed your leaky single-handle bathtub faucet!
