how to fix a leaky bathtub faucet

To fix a leaky bathtub faucet, the approach depends on whether you have a single-handle or two-handle faucet. Here are the general steps for each type:

Fixing a Two-Handle Bathtub Faucet Leak

1. Identify the Leaking Side
   Determine if the hot or cold side is leaking by feeling the temperature of the dripping water. If unsure, you may need to repair both sides

2. Turn Off the Water Supply
   Shut off the main water supply valve to your home. Open the bathtub faucets to drain any remaining water. Cover the drain to prevent losing small parts

3. Remove Faucet Handle and Escutcheon
   Pry off the handle cap with a flathead screwdriver, unscrew the handle, and remove it. Then remove the decorative escutcheon plate by unscrewing or pulling it off

4. Remove Stem Assembly
   Loosen the brass nut securing the stem assembly with an adjustable wrench and pull the stem out. If stuck, use penetrating oil or a special bath socket wrench

5. Replace the Rubber Washer
   Unscrew and remove the old rubber washer from the back of the stem assembly. Clean the area and install a new washer with screws

6. Inspect and Replace Faucet Seat if Needed
   Check the faucet seat inside the valve opening for corrosion or damage. Use a seat wrench to remove and replace it if faulty

7. Reassemble the Faucet
   Put the stem assembly back, secure it with the brass nut, replace the escutcheon, and reinstall the handle and cap

8. Turn Water Back On and Test
   Open the main water valve slowly and check for leaks

Fixing a Single-Handle Bathtub Faucet Leak

1. Turn Off Water Supply and Drain Faucet
   Shut off water at the main valve and open the faucet to drain remaining water

2. Remove Faucet Handle and Escutcheon
   Pry off the handle cap, remove the screw (using an Allen wrench if needed), and slide off the handle. Remove the escutcheon and a U-shaped retainer clip with needle-nose pliers

3. Remove and Replace Valve Cartridge
   Note the cartridge position, then pull it out with pliers or a cartridge puller tool. Insert the new cartridge in the same orientation and replace the retainer clip

4. Reassemble Faucet and Test
   Replace the escutcheon and handle, tighten screws, turn the water back on, and check for leaks

Additional Tips

• If the handle is stuck, gently heat it with a hair dryer or pour hot water to loosen it

• Use a towel over the drain to avoid losing small parts

• If leaks persist after these repairs, it may be necessary to call a professional plumber

By following these steps carefully, you can fix most common bathtub faucet leaks yourself, saving water and preventing higher utility bills
