Bathtub Faucet Leaking

How to Fix a Leaking Bathtub faucet

Most leaky bathtub faucet problems can be fixed with replacement part available at any home center or hardware store. There are hundreds of thousands of faucet parts available, so it’s a good idea to bring in your old parts for an exact match. If you notice that the valve is highly corroded, or that the finished is rather worn, you may want to replace your entire faucet set.

  1. Look for access to the bathtub faucet’s shut-off valves and turn off the water supply. If the shut-off valves are not accessible, turn off your home’s main water supply.
  2. Pry the buttons off of your double-handled faucet with a flat-blade screwdriver, exposing the handle’s screws. Remove these screws with a Philips screwdriver. Once removed, pull the handles off to expose the faucet’s stems.
  3. Place the socket over each one of the faucet stems and turn counterclockwise. If the stem appears to be frozen, remove and apply penetrating lubricant spray to each of the threads. Allow 15 to 20 minutes for the lubricant spray to work. Slide the socket back over the stem and turn counterclockwise to remove.
  4. Inset your sear wrench into the remaining opening. Turn counterclockwise to remove the remaining seats. Spray the liquid sealant onto the threads of the new seats. Install with a wrench and tighten clockwise to secure.
  5. Use the Phillips screwdriver to take off the seat washer screws from the ends of the stems. Pry out the old seat washers and install the new ones. Secure the new washer with new seat washer screws.
  6. Use the liquid thread sealant to coat the threads of the stems. Insert the stems back into the opening of the faucet. Tighten the stems clockwise using the shower stem socket.
  7. Cover the stems with your faucet’s handles. Secure the handles with the handle screws. Replace the handle buttons back into place to cover the screws. Test for leaks by turning on the water supply.
