A bathtub faucet leaking from the spout is a common household problem that can lead to wasted water, higher utility bills, and potential damage to your bathroom fixtures. If you’ve noticed your bathtub faucet dripping even when turned off, it’s time to take action.
In this comprehensive guide, we’ll discuss the common causes of a bathtub faucet leaking from the spout, step-by-step solutions to fix it, and tips to prevent future leaks.
Why Is My Bathtub Faucet Leaking from the Spout?
Several factors can cause a bathtub faucet to leak. Understanding the root cause can help you determine the right fix.
1. Worn-Out Washers
The most common reason for a leaking bathtub faucet is a worn-out washer. Over time, washers can deteriorate due to constant exposure to water pressure, leading to leaks.
2. Faulty Cartridge or Valve
Modern bathtub faucets often use a cartridge or valve system to control water flow. If the cartridge inside the faucet handle is damaged, it can cause continuous dripping.
3. Corroded or Damaged Faucet Seat
The faucet seat connects the faucet and the plumbing system. Corrosion or mineral buildup can prevent the washer from sealing properly, leading to a leak.
4. High Water Pressure
Excessive water pressure can cause leaks by putting stress on the faucet’s internal components. If your water pressure is too high, it might cause water to leak even when the faucet is turned off.
5. Loose or Faulty Faucet Handles
If the faucet handles are loose, they may not completely shut off the water supply, resulting in dripping water.
How to Fix a Bathtub Faucet Leaking from the Spout
Step 1: Turn Off the Water Supply
Before making any repairs, turn off the water supply to avoid flooding or water damage. You can usually find the shut-off valve under the sink or in a utility room.
Step 2: Remove the Faucet Handle
Use a screwdriver or wrench to remove the faucet handle. If it’s stuck, you might need a handle puller to remove it without damaging the fixture.
Step 3: Inspect and Replace the Washer
- Take out the old washer and inspect it for signs of wear.
- If it’s damaged, replace it with a new one of the same size.
- Apply plumber’s grease before reassembling the faucet.
Step 4: Check and Replace the Cartridge
- If your bathtub faucet uses a cartridge system, remove the old cartridge and install a new one.
- Ensure it fits correctly before securing it in place.
Step 5: Clean or Replace the Faucet Seat
- Inspect the faucet seat for any buildup or corrosion.
- Use a seat wrench to remove and replace the seat if necessary.
- If there’s only minor debris, clean it using vinegar or a cleaning solution.
Step 6: Reassemble the Faucet and Turn On the Water
- Once all parts are replaced and secured, reattach the faucet handle.
- Turn the water supply back on and check for leaks.
Preventing Future Bathtub Faucet Leaks
Once you’ve fixed the issue, taking preventive measures can help you avoid future leaks.
1. Regular Maintenance
- Inspect your faucet washers and cartridges regularly.
- Replace any worn-out parts before they cause a leak.
2. Monitor Water Pressure
- High water pressure can damage plumbing fixtures over time.
- Install a pressure regulator to keep water pressure at a safe level.
3. Keep Your Faucet Clean
- Regularly clean your faucet to prevent mineral deposits from accumulating.
- Use vinegar or a mild cleaning solution to remove hard water stains and debris.
4. Fix Small Leaks Immediately
- A minor leak can quickly turn into a bigger issue.
- Address any dripping faucets as soon as you notice them.
When to Call a Professional Plumber
While DIY repairs can fix most bathtub faucet leaks, some situations may require professional assistance. Call a plumber if:
- The leak persists even after replacing the washer and cartridge.
- You notice water damage around the faucet or walls.
- There are underlying plumbing issues, such as pipe corrosion or hidden leaks.
