Is the constant drip, drip, drip of your bathtub faucet driving you crazy? A leaky tub faucet isn’t just annoying—it’s also a major water waster that can lead to higher bills over time. Fortunately, learning how to fix a leaky tub faucet is easier than you might think! With just a few tools and some basic know-how, you can stop the drip and save money. This guide will show you exactly how to fix a leaky bathtub faucet in seven easy steps.
What You’ll Need:
- Flathead and Phillips screwdrivers
- Adjustable wrench or pliers
- Plumber’s grease
- Replacement parts (washer, O-ring, or cartridge, depending on your faucet type)
- Safety gloves
- Towel
1. Turn Off the Water Supply
Before you begin fixing your leaky tub faucet, turn off the water supply. Look for shut-off valves under the sink or near the bathtub. If you can’t locate individual valves, you might need to turn off the main water supply for your home. Once the water is off, turn on the bathtub faucet to drain any remaining water from the pipes.
2. Remove the Faucet Handle
To start repairing your leaky bathtub faucet, use a flathead screwdriver to gently remove the decorative cap on the faucet handle. Underneath, you’ll find a screw that secures the handle to the faucet. Remove this screw with a Phillips screwdriver and carefully pull the handle off the faucet assembly. If the handle is stuck, try wiggling it or gently tapping it with a rubber mallet to loosen it.
3. Inspect the Valve Stem or Cartridge
With the handle removed, you’ll see the valve stem or cartridge. This is the part that controls water flow and is often the source of the leak. Use an adjustable wrench to unscrew and remove the valve stem or cartridge from the faucet body. Carefully inspect the removed parts for any signs of wear, corrosion, or damage.
4. Identify the Problem and Replace Parts
Look closely at the valve stem or cartridge for worn-out washers, O-rings, or any damaged parts. These are common causes of a leaky tub faucet. Take the worn parts with you to the hardware store to find exact replacements.
- Compression Faucets: Usually have rubber washers and O-rings that need replacing.
- Cartridge Faucets: May require replacing the entire cartridge if it shows signs of wear or damage.
5. How to Fix a Leaky Bathtub Faucet with Two Handles
If your bathtub faucet has two handles—one for hot water and one for cold water—the process to fix a leaky bathtub faucet is slightly different but just as straightforward. Here’s how to tackle this specific type of leak:
- Turn Off the Water Supply: As with any plumbing job, start by turning off the water supply to your tub. Ensure both handles are turned to the “off” position, and drain any remaining water from the faucet.
- Remove Both Handles: Use a flathead screwdriver to remove the decorative caps on both handles. Unscrew the screws beneath the caps with a Phillips screwdriver and carefully pull each handle away from the wall.
- Inspect Both Valve Stems or Cartridges: With a two-handle faucet, you’ll need to inspect both valve stems or cartridges. Use an adjustable wrench to remove each valve stem or cartridge. Check for worn washers, O-rings, or other parts that might be causing the leak. It’s often the case that the leak is on the hot water side, but it’s best to check both.
- Replace the Necessary Parts: Depending on your findings, replace any worn-out washers, O-rings, or entire cartridges. Apply plumber’s grease to the new parts for a secure seal, and reinsert them into the faucet body.
- Reattach the Handles: Once the new parts are in place, reattach both handles and secure them with their screws. Replace the decorative caps, ensuring everything is aligned correctly.
- Turn the Water Back On and Test: Turn the water supply back on and test both handles to ensure the leak is fixed. Check that water flows properly from each side and that no drips remain.
Fixing a leaky bathtub faucet with two handles might take a bit more time since you’re working with two separate components, but the process is straightforward. By addressing both handles, you ensure that your bathtub faucet is leak-free and functioning properly.
6. Apply Plumber’s Grease and Reassemble
Before reassembling the faucet, apply a thin layer of plumber’s grease to the new parts. This will ensure a tight seal and prevent future leaks. Insert the new parts or cartridge back into the faucet body and tighten them with the wrench, being careful not to overtighten. Proper tightening is crucial for a leak-free seal.
7. Reattach the Handle
Once the new parts are in place, reattach the faucet handle. Secure it with the screw you removed earlier and replace the decorative cap. Make sure the handle is aligned correctly and moves smoothly.
8. Turn the Water Back On and Test
Turn the water supply back on at the shut-off valves. Slowly open the faucet to test for leaks. If the water flows smoothly and there are no drips, you’ve successfully fixed your leaky bathtub faucet! If you still notice a leak, double-check that all parts are securely installed and tightened properly.
Quick Tips for Fixing a Leaky Bathtub Faucet:
- Match Replacement Parts Exactly: Bring your old parts to the hardware store to ensure you get the correct replacements.
- Use Plumber’s Grease: This helps create a tight seal and prevents future leaks.
- Know Your Faucet Type: Determine if you have a compression, cartridge, ball, or ceramic-disk faucet to find the right replacement parts.
By following these steps on how to fix a leaky tub faucet, you’ve resolved one of the most common plumbing problems. You’ll save water, reduce your utility bills, and enjoy a peaceful, drip-free bathroom.
