How To Fix a Dripping Bathtub Faucet: A DIY Guide
A dripping bathtub faucet is more than just annoying; it wastes water and can drive up your utility bills. Luckily, fixing a dripping faucet is often a manageable DIY project, saving you the cost of a plumber. This guide will walk you through the common causes and solutions, empowering you to tackle this common household problem.
Identifying the Problem: What Type of Faucet Do You Have?
Before you begin, it's crucial to identify the type of faucet you have. There are several common types, each requiring slightly different approaches to repair:
- Compression Faucets: These older faucets use separate hot and cold handles that tighten a compression washer to stop the water flow. Dripping is often due to a worn washer.
- Cartridge Faucets: These faucets have a single handle that controls both temperature and flow. A cartridge is a single unit containing all the internal mechanisms. Dripping usually indicates a worn or damaged cartridge.
- Ball Faucets: Similar to cartridge faucets, these have a single handle but utilize a ball-shaped mechanism. Dripping typically points towards a worn-out ball or O-rings.
- Ceramic Disc Faucets: These faucets use two ceramic discs to control water flow. Dripping usually signals a problem with the discs themselves.
Tools You'll Need:
Before you start, gather the necessary tools. This will make the repair process smoother and more efficient. You'll likely need:
- Screwdrivers (Phillips and Flathead): For removing faucet handles and other components.
- Adjustable Wrench: To loosen and tighten nuts and other fittings.
- Basin Wrench: A specialized wrench for accessing hard-to-reach nuts under the sink.
- Pliers: For gripping and turning small parts.
- Putty Knife: For removing old caulk or sealant.
- Replacement Parts: This is crucial! You'll need to find replacement parts specific to your faucet type (washers, cartridges, O-rings, etc.). Take a picture of your faucet's internal components before disassembling to help with matching parts at the hardware store.
- Container: To catch any remaining water in the pipes.
- Old towels: To protect your sink and floor.
Step-by-Step Guide (Compression Faucet Example):
This example focuses on a compression faucet, one of the more common types. Remember, procedures will vary slightly depending on your faucet type. Always turn off the water supply to the faucet before beginning any repairs.
1. Turn Off the Water Supply
Locate the shut-off valves under your sink for both hot and cold water lines. Turn them clockwise to completely shut off the water flow.
2. Remove the Handles
Carefully remove the decorative caps on the faucet handles. You'll usually find small screws underneath; use the appropriate screwdriver to remove them. Then, unscrew the handles themselves.
3. Remove the Packing Nuts
Once the handles are off, you'll see packing nuts. Use an adjustable wrench or basin wrench to carefully loosen and remove these nuts. This will expose the stems and the worn washers.
4. Replace the Washers
Carefully remove the old washers. Compare them to the new ones to ensure a proper fit. Install the new washers onto the stems, ensuring they are properly seated.
5. Reassemble the Faucet
Reassemble the faucet in reverse order, tightening all nuts and screws securely. Don't overtighten, as this can damage the parts.
6. Turn the Water Supply Back On
Slowly turn the water supply valves counterclockwise to turn the water back on. Check for any leaks. If the dripping persists, you might need to repeat the process or consider a different issue.
Troubleshooting and Other Faucet Types
If your faucet is still dripping after replacing the washers (or cartridge, etc.), here are some troubleshooting tips:
- Inspect the Stems: Look for any signs of damage or wear on the stems themselves. These might need replacing as well.
- Check O-rings: O-rings are crucial for creating watertight seals. If they're cracked or worn, replace them.
- Consider the Cartridge/Ball: For cartridge and ball faucets, the entire cartridge or ball assembly may need to be replaced.
- Professional Help: If you're uncomfortable working on plumbing, or if the problem persists after trying these steps, it's always best to call a qualified plumber.
Fixing a dripping bathtub faucet can be a rewarding DIY project. By following these steps and understanding your faucet type, you can save money and water while gaining valuable home maintenance skills. Remember safety first, and don't hesitate to seek professional help when needed.
