Is that constant drip, drip, drip from your bathtub faucet driving you crazy and inflating your water bill? A leaky faucet is a common household problem, but thankfully, it's often a repair you can tackle yourself. This guide will walk you through how to fix a leaky bathtub faucet, saving you money and the hassle of calling a plumber.

Identifying the Faucet Type

Before you grab your tools, it's crucial to identify what type of faucet you're dealing with. Bathtub faucets generally fall into a few categories:

  • Compression Faucets: These are the oldest type, with separate hot and cold handles. You'll usually need to tighten them firmly to stop the water flow.
  • Cartridge Faucets: These have a single lever that controls both temperature and water flow. They're known for their smooth operation.
  • Ball Faucets: Similar to cartridge faucets, ball faucets also use a single lever but have a more complex internal mechanism.
  • Ceramic Disc Faucets: These are the most modern type, also using a single lever and offering precise temperature and flow control. They're known for their durability.

Tools You'll Need

Gathering the right tools beforehand will make the repair process much smoother. Here’s a basic list:

  • Screwdrivers (both flathead and Phillips head)
  • Adjustable wrench
  • Pliers
  • Penetrating oil
  • New faucet parts (O-rings, washers, cartridge – depending on the faucet type)
  • Cloth or towel to protect the tub finish

Step-by-Step Repair Guide

Important Safety First: Before starting any plumbing work, always turn off the water supply to the bathtub. You'll usually find shut-off valves under the sink or in the basement. If you can't locate them, turn off the main water supply to your house.

1. Compression Faucet

  • Remove the Handle: Typically, there's a screw under a decorative cap on the handle. Remove the cap, unscrew the screw, and gently pull off the handle.
  • Loosen the Packing Nut: Use an adjustable wrench to loosen the packing nut that holds the stem in place.
  • Remove the Stem: Carefully remove the stem, which will likely have a rubber washer at the end. This washer is often the culprit for leaks.
  • Replace the Washer: Replace the old washer with a new one of the same size and shape. You might also want to replace the O-ring on the stem.
  • Reassemble the Faucet: Put the stem back in, tighten the packing nut, and reattach the handle.

2. Cartridge Faucet

  • Remove the Handle: Similar to compression faucets, there's usually a screw holding the handle in place. Remove the screw and handle.
  • Remove the Retaining Clip: You'll find a retaining clip that holds the cartridge in place. Use pliers to carefully remove it.
  • Pull Out the Cartridge: The cartridge might be stiff, so use pliers and wiggle it gently to pull it straight out.
  • Replace the Cartridge: Install the new cartridge, making sure it's aligned correctly. Replace the retaining clip.
  • Reassemble the Faucet: Reattach the handle and tighten the screw.

3. Ball Faucet

  • Loosen the Setscrew: Locate the setscrew on the side of the handle and loosen it with an Allen wrench.
  • Remove the Handle: Pull off the handle.
  • Loosen the Cap and Collar: Use a spanner wrench or adjustable wrench to loosen the cap and collar.
  • Remove the Ball and Seats: Carefully lift out the ball. Underneath, you'll find the seats and springs. Inspect these for wear and replace if necessary.
  • Replace O-rings and Springs: Replace any worn O-rings and springs.
  • Reassemble the Faucet: Reassemble the faucet in reverse order, making sure everything is tightened properly.

4. Ceramic Disc Faucet

  • Remove the Handle: As with other faucets, remove the handle by loosening the screw.
  • Remove the Escutcheon Cap: You might need to unscrew or pry off the escutcheon cap.
  • Remove the Ceramic Cylinder: Carefully lift out the ceramic cylinder.
  • Inspect and Clean: Inspect the cylinder and the valve body for any debris or mineral deposits. Clean if necessary.
  • Replace Seals: Replace any worn seals or O-rings.
  • Reassemble the Faucet: Reassemble the faucet in reverse order.

Testing and Final Checks

Once you've reassembled the faucet, turn the water supply back on slowly. Check for leaks around the handle and spout. If you still see leaks, double-check that all connections are tight and that you've replaced all the worn parts.

When to Call a Plumber

If you've tried these steps and the faucet is still leaking, or if you're uncomfortable performing the repairs yourself, it's best to call a qualified plumber. They have the expertise and tools to diagnose and fix more complex plumbing problems.
