A leaky bathtub faucet is more than just annoying; it wastes water and can lead to higher utility bills. Fortunately, fixing a leaky faucet is often a manageable DIY project. This guide provides a step-by-step approach to tackling this common plumbing problem, saving you money and frustration.
Identifying the Type of Faucet
Before you begin, it's crucial to identify the type of faucet you have. There are several common types, including:
- Compression Faucets: These older faucets use separate hot and cold handles that tighten compression washers to stop water flow. Leaks often originate from worn washers.
- Cartridge Faucets: These faucets have a single handle that controls both temperature and water flow. A cartridge mechanism inside the faucet controls water flow. Leaks often indicate a worn or damaged cartridge.
- Ball Faucets: These faucets also feature a single handle, but they use a ball-shaped mechanism to control water flow. Leaks usually point to a worn O-ring or damaged ball.
Tools You'll Need
Gather these essential tools before you start:
- Screwdrivers (Phillips and flathead): For removing faucet handles and other components.
- Adjustable Wrench: For loosening and tightening nuts and other fittings.
- Pliers: For gripping and turning small parts.
- Basin Wrench: Essential for accessing hard-to-reach nuts under the sink.
- Putty Knife: For removing old putty or sealant.
- Replacement Parts: This depends on your faucet type (washers, cartridges, O-rings, etc.). It's best to take the old parts to a hardware store for a precise match.
- Old Towels or Rags: To protect the sink and absorb any spills.
- Flashlight: To illuminate the work area under the sink.
Step-by-Step Repair Guide (Compression Faucet Example)
This guide focuses on repairing a compression faucet. The process for cartridge and ball faucets is similar but involves different components.
1. Turn Off the Water Supply: Locate the shut-off valves under the sink for both hot and cold water. Turn them clockwise to shut off the water supply completely. This is crucial to prevent further water damage.
2. Remove the Faucet Handles: Use the appropriate screwdriver to remove the handle caps (often decorative). Then, remove the handles themselves. You may need to use pliers or a wrench to loosen stubborn handles.
3. Remove the Packing Nuts and Stems: Locate the packing nuts beneath the handles. Use an adjustable wrench or pliers to loosen and remove them. The stems (also called spindles) should now be easily removed.
4. Inspect and Replace the Washers: Examine the washers at the bottom of each stem. If they are worn, cracked, or damaged, replace them with new ones. Make sure you purchase the correct size washers for your faucet.
5. Reassemble the Faucet: Carefully reassemble the faucet in reverse order of disassembly. Ensure the stems are properly seated and the packing nuts are tightened securely but not overtightened.
6. Turn the Water Supply Back On: Slowly turn the shut-off valves counterclockwise to restore the water supply. Check for any leaks around the faucet handles and connections.
Troubleshooting
If your leak persists after replacing the washers, you might have a more serious problem:
- Worn Stems: Stems can become worn and need replacing.
- Cracked Faucet Body: A crack in the faucet body might require replacing the entire faucet.
- Damaged O-rings (in Cartridge or Ball Faucets): Replace the O-rings to solve leaks in cartridge or ball faucets.
When to Call a Plumber
While fixing a leaky faucet is often a DIY project, some situations require professional help:
- You're uncomfortable working with plumbing.
- You cannot identify the type of faucet.
- The leak persists after attempting repairs.
- The damage is extensive.
By following these steps, you can effectively fix your leaky bathtub faucet and save water and money. Remember safety first, and don't hesitate to call a professional if you encounter any difficulties.
