Fixing a Leaking Bathtub Faucet: DIY Repair

Fixing a leaking bathtub faucet can be a frustrating and costly problem if left unattended. Not only does it waste water, but it can also lead to water damage and higher utility bills. However, with a little DIY know-how, you can easily repair a leaking bathtub faucet on your own. In this comprehensive guide, we will walk you through the step-by-step process of fixing a leaking bathtub faucet, from identifying the problem to completing the repair. So, grab your tools and let’s get started!

1. Identify the Type of Faucet

The first step in fixing a leaking bathtub faucet is to identify the type of faucet you have. There are four common types of bathtub faucets: compression faucets, ball faucets, cartridge faucets, and disc faucets. Each type requires a slightly different repair approach, so it’s important to know which one you’re dealing with.

To identify the type of faucet, start by turning off the water supply to the bathtub. Then, remove the handle of the faucet by unscrewing the screw or nut holding it in place. Once the handle is removed, you should be able to see the inner workings of the faucet and determine its type.

For example, if you see a central valve stem with a rubber washer at the bottom, you have a compression faucet. If you see a single lever controlling both the temperature and flow of water, you have a ball faucet. If you see a cartridge that can be pulled out, you have a cartridge faucet. And if you see a flat, circular disc with holes, you have a disc faucet.

2. Gather the Necessary Tools and Materials

Before you start the repair process, it’s important to gather all the necessary tools and materials. Having everything on hand will save you time and frustration during the repair. Here are some common tools and materials you may need:

  • Adjustable wrench
  • Screwdriver (flathead or Phillips, depending on the faucet type)
  • Replacement parts (such as washers, O-rings, cartridges, or discs)
  • Plumber’s tape
  • Bucket or towel to catch any water

Make sure to check the specific requirements for your faucet type and have any additional tools or materials ready.

3. Turn Off the Water Supply

Before you begin disassembling the faucet, it’s crucial to turn off the water supply to prevent any accidents or further leakage. Locate the shut-off valves for the bathtub and turn them clockwise until they are fully closed. If you can’t find the shut-off valves, you may need to shut off the main water supply to your house.

Once the water supply is turned off, open the faucet to release any remaining water pressure. This will help prevent any water from spraying when you start working on the faucet.

4. Disassemble the Faucet

Now that the water supply is turned off, it’s time to disassemble the faucet and access the internal components. Follow these steps to disassemble the most common types of bathtub faucets:

Compression Faucet

  1. Remove the handle by unscrewing the screw or nut holding it in place.
  2. Use an adjustable wrench to unscrew the packing nut located just below the handle.
  3. Once the packing nut is removed, you should see the valve stem. Use a wrench to unscrew the valve stem in a counterclockwise direction.
  4. Inspect the rubber washer at the bottom of the valve stem. If it’s worn or damaged, replace it with a new one.
  5. Check the seat inside the faucet body for any signs of damage or corrosion. If necessary, use a seat wrench to remove and replace the seat.

Ball Faucet

  1. Remove the handle by unscrewing the screw or nut holding it in place.
  2. Use pliers to unscrew the cap and collar assembly located just below the handle.
  3. Once the cap and collar assembly is removed, you should see the ball and cam assembly. Lift it out of the faucet body.
  4. Inspect the rubber O-rings around the ball and replace them if they are worn or damaged.
  5. Check the springs and seats inside the faucet body for any signs of damage. If necessary, replace them with new ones.

  2. Use pliers to remove the retaining clip or nut that holds the cartridge in place.
  3. Once the retaining clip or nut is removed, you can pull the cartridge straight out of the faucet body.
  4. Inspect the cartridge for any signs of damage or wear. If necessary, replace it with a new one.

Disc Faucet

  1. Remove the handle by unscrewing the screw or nut holding it in place.
  2. Use pliers to unscrew the cap and collar assembly located just below the handle.
  3. Once the cap and collar assembly is removed, you should see the disc cartridge. Lift it out of the faucet body.
  4. Inspect the cartridge for any signs of damage or wear. If necessary, replace it with a new one.

5. Replace Faulty Components

Now that you have disassembled the faucet and identified the faulty components, it’s time to replace them with new ones. Here are some common components that may need to be replaced:

  • Washers: Compression faucets have rubber washers that can wear out over time. Replace them with new ones of the same size.
  • O-rings: Ball and cartridge faucets have rubber O-rings that can become worn or damaged. Replace them with new ones of the same size.
  • Cartridges: Cartridge and disc faucets have cartridges that control the flow and temperature of water. Replace them with new ones that match the old cartridge.
  • Seats: Compression faucets have seats that can become corroded or damaged. Replace them with new ones of the same size.
