A dripping faucet might seem like a minor annoyance, but that constant drip, drip, drip can quickly add up to wasted water and a hefty bill. Plus, a persistent leak can lead to more significant plumbing problems down the line. This guide provides a step-by-step walkthrough on how to fix a leaky faucet, making this common household repair accessible to everyone, regardless of your DIY experience.
Identifying the Type of Faucet
Before you grab your tools, you need to identify the type of faucet you have. There are three main types:
- Compression Faucets: These older style faucets have separate hot and cold handles that turn to control water flow. They usually feature a separate handle for each temperature.
- Cartridge Faucets: These faucets have a single handle that controls both temperature and water flow. They utilize a cartridge—a single unit containing several internal parts—that needs replacing if the faucet is leaking.
- Ball Faucets: These also feature a single handle, but instead of a cartridge, they use a ball-shaped valve to control water flow. Leaks in ball faucets often indicate a problem with the ball itself or its seals.
Knowing your faucet type is crucial in determining the best repair approach.
Tools You'll Need
Gathering the necessary tools beforehand will streamline the repair process. You'll likely need:
- Screwdrivers: Phillips and flathead screwdrivers in various sizes.
- Adjustable Wrench: For loosening and tightening nuts and fittings.
- Pliers: Needle-nose pliers can be particularly helpful for reaching small parts.
- Basin Wrench: This specialized tool allows you to reach and tighten nuts underneath the sink.
- Replacement Parts: The specific parts you need depend on your faucet type. It's best to take a picture of your faucet or bring a sample of the old parts to a hardware store for assistance.
- Penetrating Oil (optional): This can help loosen stubborn nuts and bolts.
- Container: To catch any leftover water.
- Old Towels: To protect your sink and prevent water damage.
Fixing a Leaky Compression Faucet
This is typically the most straightforward repair.
Step 1: Turn Off the Water Supply
Locate the shut-off valves under the sink for both hot and cold water. Turn them clockwise to stop the water flow.
Step 2: Remove the Handles
Carefully remove the decorative caps on the handles. These are often held in place by small screws. Use the appropriate screwdriver to remove the screws and take off the caps. Next, unscrew the handle itself, typically using a screwdriver or an adjustable wrench.
Step 3: Replace the Washers
Once the handles are off, you'll see the stems. Unscrew the stems and replace the worn washers at the bottom. These are usually small, rubber-like discs.
Step 4: Reassemble
Carefully reassemble the faucet, tightening all parts securely but not too tightly. Turn the water back on and check for leaks.
Fixing a Leaky Cartridge or Ball Faucet
These repairs are slightly more complex and may require replacing the entire cartridge or ball assembly.
Step 1: Turn Off the Water Supply
Again, turn off the water supply under the sink.
Step 2: Remove the Handle
The process for removing the handle varies slightly depending on the faucet model. Often, there’s a retaining clip or screw underneath the handle that needs to be removed first.
Step 3: Remove the Cartridge or Ball
Once the handle is removed, you'll have access to the cartridge or ball assembly. This may require unscrewing a nut or retaining ring. Carefully remove the old cartridge or ball.
Step 4: Install the New Part
Install the new cartridge or ball assembly and reassemble the faucet. Ensure everything is tightened securely.
Step 5: Turn the Water Back On and Check for Leaks
Turn the water back on and carefully check for any leaks.
When to Call a Plumber
While many faucet leaks can be repaired at home, some situations require professional help:
- Persistent Leaks After Repair: If you’ve tried the above steps and the faucet still leaks, a professional plumber might be needed.
- Extensive Water Damage: If a leak has caused significant water damage, call a plumber immediately.
- Complex Faucet Types: If you have an unusually complex or antique faucet, it's best to contact a plumbing professional.
- Lack of Confidence: If you are not comfortable working with plumbing, it's always best to call a qualified plumber.
By following these steps, you can confidently tackle that leaky faucet and save money and water in the process. Remember, safety is paramount, so if you’re unsure about any step, it’s always best to consult a professional.
