## Tools and Materials Needed Before starting the repair, gather these essential items: - Adjustable wrench - Phillips and flathead screwdrivers - Replacement parts (washers, O-rings, or cartridge) - Plumber's tape - Plumber's grease - Clean rags - White vinegar - Allen wrench (if needed) - Penetrating oil (optional) ## Preparation Steps 1. Turn off the water supply to your bathtub (usually at the main water valve) 2. Cover the drain with a rag to prevent losing small parts 3. Remove any decorative caps on the faucet handles ## Diagnosing the Problem Before starting repairs, identify your faucet type - most modern faucets use either a **cartridge system** or traditional **compression stems**.

Common causes of leaks include: - Worn rubber washers - Damaged O-rings - Corroded valve seats - Cracked cartridges - Mineral buildup ## Step-by-Step Repair Process ### 1. Remove the Faucet Handle - Locate the mounting screw (often hidden under a decorative cap) - Use a flathead screwdriver to remove the cap - Unscrew the handle using a Phillips screwdriver or Allen wrench - Carefully pull off the handle ### 2. Access the Stem or Cartridge - Remove the escutcheon plate (decorative plate behind handle) - Unscrew the packing nut with an adjustable wrench - Extract the stem or cartridge - Apply penetrating oil if stuck ### 3. Replace Damaged Parts For cartridge faucets: ``` 1. Pull the cartridge straight out 2. Note its orientation 3. Insert new cartridge in exactly the same position 4. Ensure proper alignment before tightening ``` For compression faucets: ``` 1. Unscrew the stem assembly 2. Replace washers and O-rings 3. Clean valve seat with vinegar 4. Apply plumber's grease to new parts ``` ### 4. Reassemble the Faucet 1. Reinsert stem or cartridge 2. Tighten the packing nut 3. Reattach escutcheon plate and handle 4. Turn water supply back on 5. Test for leaks ## Tips for Success * Take photos during disassembly * Organize parts in removal order * Use plumber's tape on threads * Don't overtighten components * Clean all parts thoroughly * Consider replacing both handles' components > Regular maintenance can prevent future leaks and extend your faucet's life.
