How to Fix a Bathtub Faucet Leak: Step-by-Step Guide

A leaky bathtub faucet can be a nuisance and waste water, leading to increased water bills and potential damage to your bathroom. If you're facing a leaky faucet, here's a comprehensive step-by-step guide to help you fix it:

1. Gather Necessary Tools and Materials:

- Adjustable wrench - Phillips head screwdriver - Flat head screwdriver - Pliers - New faucet cartridge (if required) - New faucet washer (if required) - Teflon tape - Plumber's putty - Rag or towel

2. Turn Off the Water Supply:

- Locate the water supply valves for your bathtub faucet. These valves are usually located under the sink or behind the faucet. - Turn the valves clockwise to shut off the water supply completely.

3. Remove the Faucet Handle:

- Use the Phillips head screwdriver to remove the screws holding the faucet handle in place. - Once the screws are removed, pull the faucet handle straight up to detach it from the faucet body.

4. Remove the Faucet Stem:

- Locate the faucet stem, which is the cylindrical part of the faucet that connects the handle to the cartridge. - Use the adjustable wrench to loosen the packing nut that holds the faucet stem in place. - Once the packing nut is loose, remove the faucet stem by turning it counterclockwise.

5. Inspect the Faucet Cartridge:

- Examine the faucet cartridge for any signs of damage or wear. If the cartridge is damaged or worn, it needs to be replaced. - To remove the cartridge, use the pliers to grasp the cartridge and turn it counterclockwise until it comes out.

6. Install a New Faucet Cartridge (if Required):

- If you're replacing the faucet cartridge, insert the new cartridge into the faucet body. - Turn the cartridge clockwise until it is snug. - Apply a small amount of plumber's putty around the base of the cartridge to help seal it.

7. Replace the Faucet Stem:

- Insert the faucet stem back into the faucet body. - Hand-tighten the packing nut until it is snug. - Use the adjustable wrench to tighten the packing nut further, but do not overtighten it.

8. Reattach the Faucet Handle:

- Position the faucet handle back onto the faucet stem. - Secure the faucet handle with the screws that you removed earlier.

9. Test the Faucet:

- Turn on the water supply valves to allow water to flow through the faucet. - Check for any leaks around the faucet handle or the base of the faucet. - If there are no leaks, the repair is successful.

10. Clean Up:

- Use the rag or towel to wipe away any excess water or debris from the faucet and surrounding area.

Remember:

- If you're unsure about any step in the process or encounter unexpected issues, it's always best to consult a qualified plumber for assistance. - Make sure to use the correct tools and materials for the specific type of faucet you have. - Always turn off the water supply before attempting any repairs to avoid water damage.
