A dripping bathtub faucet is more than just an annoying sound—it’s a sign that something isn’t quite right with your plumbing. The constant drip not only wastes water but can also lead to higher utility bills over time. If you’re wondering, “Why is my bathtub faucet dripping?”
There are several reasons why this might be happening, and in many cases, it’s something you can fix yourself.
In this article, we’ll explore the common causes of a leaking bathtub faucet, from worn-out washers to damaged cartridges.
We’ll also guide you through the steps to repair it, helping you save money and prevent further damage. So, let’s dive in and find out what might be causing that persistent drip!
Common Causes of a Dripping Bathtub Faucet
Before diving into repairs, it’s essential to understand the underlying causes of a dripping bathtub faucet. By identifying the issue early on, you can prevent further damage and avoid expensive repairs.
- Worn Out Washers
A cracked or worn washer in the stem is one of the most common reasons for a bathtub faucet to drip. Every time the water is turned on, the washer is pushed against the valve, which causes friction. Over time, this friction wears down the rubber, leading to leaks. - Faulty Faucet Cartridge
If your faucet uses a cartridge system, this could be the culprit. The cartridge is responsible for controlling the water flow, and when it wears out or gets damaged, it may fail to completely block the water from flowing, leading to a drip. - Damaged Faucet Handles
If the faucet handle is old or damaged, it may not fully close, allowing water to leak out. Rust and corrosion can also weaken the handle over time. - Cracked Valve or Pipe
In some cases, the issue may be more severe, with a cracked valve or a leaking pipe behind the faucet. If this is the case, a more in-depth repair will be necessary.
How to Fix a Dripping Bathtub Faucet
Now that we’ve covered the most common causes, let’s move on to the steps to fix a dripping bathtub faucet. You don’t need to be a professional plumber to solve this issue yourself. With a few tools and a bit of patience, you can restore your faucet to its original condition.
Step 1: Turn Off the Water Supply
Before beginning any repair work, the first thing you need to do is shut off the water supply to your home. This step is critical in ensuring you don’t cause any additional leaks or accidents.
- Where to Find the Shut-Off Valve: Typically, the shut-off valve can be found near your water heater or the water meter. In some homes, it may be installed outside, near the municipal meter. Use a wrench to turn it off, especially if it hasn’t been used in a while.
- Drain the Remaining Water: Once the water is off, turn the faucet to the “on” position to drain any remaining water from the pipes.
Step 2: Remove the Faucet Handle
The next step is to remove the faucet handle to access the internal components.
- Tools Needed: Use an Allen wrench or screwdriver to remove the screws securing the handle. Be sure to carefully pull the handle off once the screws are removed.
Step 3: Check the Faucet Cartridge and Washer
Now that the handle is off, it’s time to inspect the cartridge and washer. These parts are typically where the problem lies.
- Cartridge Replacement: If the cartridge is damaged, it’s best to replace it. Use a wrench to carefully remove the old cartridge. Be sure to apply plumber’s grease to the new one before installing it.
- Washer Replacement: If the washer appears worn out or cracked, replace it with a new one. You may need to use a socket wrench to loosen any screws holding it in place.
Step 4: Reassemble the Faucet
Once you’ve replaced the damaged parts, it’s time to put the faucet back together.
- Reinstall the Cartridge and Handle: Slide the new cartridge or washer back into place and secure it with the retaining clip. Reattach the handle and tighten the screws.
- Turn the Water Supply Back On: Once everything is reassembled, turn the water supply back on and test the faucet. Run water for a few minutes to ensure that the leak is gone and everything is functioning properly.
Tips for Preventing Future Leaks
Once you’ve successfully fixed your bathtub faucet, you’ll want to take some steps to ensure that the problem doesn’t return:
- Regular Maintenance: Periodically check your faucet parts for signs of wear and tear, especially the washer and cartridge. Replacing these parts at the first sign of damage can prevent more serious leaks from developing.
- Use Plumber’s Tape: When replacing faucet parts, apply plumber’s tape or Teflon tape to the threads to ensure a tight seal and prevent future leaks.
- Handle with Care: Be gentle when turning the faucet handle. Over-tightening or using excessive force can damage the internal parts, leading to leaks.
Conclusion

By understanding the common causes and following the steps above, you can repair your faucet yourself and save money. If the issue persists, don’t hesitate to contact a professional plumber to resolve the problem. With regular maintenance and the right tools, your bathtub faucet will stay leak-free for years to come!
