Key Takeaways
- Turn off the water supply and open the faucet to drain remaining water before beginning repairs.
- Remove the faucet handle by loosening the set screw and gently pulling it off for inspection.
- Inspect the faucet for worn washers, cartridges, or faulty O-rings causing the leak.

Identifying the Source of the Leak
Before you can fix a leaky bathtub faucet, you need to pinpoint exactly where the leak is coming from. Start by turning off the water supply to avoid further dripping. Dry the faucet area thoroughly, then observe closely where the water appears.
Is it dripping from the spout, the handle, or around the base? Each location suggests a different issue. A leak from the spout often means a worn-out washer or cartridge, while drips near the handle could indicate a faulty valve or O-ring.
Check for any visible cracks or corrosion on the faucet parts. Sometimes, water collects and drips slowly, making it tricky to find the source. Taking your time in this step helps guarantee you address the right component, making your repair more effective.
Gathering the Necessary Tools and Materials
Once you’ve figured out where the leak is coming from, the next step is to gather the right tools and materials to fix it. Having everything ready will make the repair faster and easier. You’ll typically need basic plumbing tools and replacement parts specific to your faucet type.
| Tool/Material | Purpose | Notes |
|---|---|---|
| Adjustable wrench | Loosens/tightens nuts | Choose one with a comfortable grip |
| Screwdrivers | Removes screws | Both flathead and Phillips |
| Replacement washers | Seals leaks | Match the size to your faucet |
| Plumber’s tape | Prevents leaks on threads | Wrap around threaded parts |
Make sure to check your faucet model before buying parts to ensure compatibility.
Shutting Off the Water Supply
Before you start fixing your leaky bathtub faucet, you’ll need to shut off the water supply. First, locate the main water valve in your home, usually found near the water meter or where the main line enters the house.
Once you find it, turn the valve clockwise to stop the water flow and prevent any leaks while you work.
Locate Main Water Valve
To stop the water flow and prevent any mess, you’ll need to locate the main water valve in your home. This valve controls the water supply to your entire house, so shutting it off will stop water from reaching your bathtub faucet.
Typically, you’ll find the main water valve near where the water line enters your home. Common locations include the basement, crawl space, garage, or outside near the foundation. Look for a round wheel or a lever handle attached to a pipe.
If you live in a colder climate, the valve might be inside to prevent freezing. Knowing exactly where this valve is before starting repairs will save you time and hassle when you need to stop water flow quickly.
Turn Off Water Supply
After locating the main water valve, the next step is to turn off the water supply to your bathtub faucet. This prevents water from flowing while you work, avoiding mess and potential damage. Typically, you’ll find the main valve near your water meter or where the main water line enters your home.
Turn the valve handle clockwise until it stops, fully shutting off the water. If your home has individual shut-off valves for each fixture, use the one for the bathtub instead. Once you’ve turned off the water, open the bathtub faucet to drain any remaining water in the pipes.
This ensures the faucet is completely dry, making repairs easier and cleaner. Now you’re ready to proceed with fixing the leak safely.
Disassembling the Faucet Handle
Although it might seem tricky at first, disassembling the faucet handle is a straightforward process once you know where to look. Start by locating the set screw, which is often hidden under a decorative cap or on the side of the handle. You’ll need a screwdriver or an Allen wrench to remove it.
Disassembling a faucet handle is simple once you find the hidden set screw under the decorative cap.
Follow these steps:
- Pry off any decorative cap gently with a flathead screwdriver.
- Use the appropriate tool to loosen and remove the set screw.
- Carefully pull the handle straight off; if it’s stuck, wiggle it gently or tap with a rubber mallet.
- Keep all screws and parts organized for easy reassembly.
Now, your faucet handle is ready for the next step of repair.
Replacing the Washer or Cartridge
Now that you’ve taken the handle apart, it’s time to find out if the washer or cartridge is causing the leak. You’ll want to carefully inspect each part to pinpoint the exact source.
Once identified, follow these steps to replace the faulty washer or cartridge and stop the drip for good.
Identifying the Leak Source
Before you can fix a leaky bathtub faucet, you need to pinpoint whether the problem lies with the washer or the cartridge. Here’s how to identify the leak source:
- Check the faucet handle – If water drips when the faucet is off, the cartridge might be worn out.
- Listen for dripping sounds – A steady drip often means the washer is damaged.
- Inspect water flow – Uneven or weak flow can signal a faulty cartridge.
- Look for water around the base – Leaks near the handle base usually indicate cartridge issues, while leaks from the spout often relate to the washer.
Knowing exactly where the leak comes from saves time and guarantees you replace the right part.
Step-by-Step Replacement Guide
Once you’ve pinpointed whether the washer or cartridge is causing the leak, you can move on to replacing the faulty part. First, turn off the water supply and open the faucet to drain any remaining water.
Next, remove the handle using a screwdriver, then carefully extract the valve stem or cartridge. Replace the worn washer or cartridge with an exact match.
Reassemble the faucet, turn the water back on, and check for leaks.
| Step | Action |
|---|---|
| 1 | Turn off water supply |
| 2 | Remove faucet handle |
| 3 | Extract valve stem/cartridge |
| 4 | Replace washer or cartridge |
| 5 | Reassemble & test for leaks |
Reassembling the Faucet and Testing for Leaks
Although reassembling the faucet might seem straightforward, taking care to align all parts correctly guarantees a proper seal and prevents future leaks. Here’s how to do it efficiently:
- Replace washers and O-rings: Ensure they’re seated properly to avoid leaks.
- Align the cartridge or valve stem: Insert it carefully, matching any tabs or grooves.
- Tighten the retaining nuts and screws: Use the right tools to avoid overtightening or stripping.
- Reattach the handle and escutcheon plate: Secure them firmly without forcing.
Once reassembled, turn the water supply back on and test the faucet. Watch closely for drips or moisture around joints.
If you spot leaks, tighten connections as needed or revisit earlier steps. Proper reassembly means your bathtub faucet should now function leak-free and smoothly.
