A leaky bathtub faucet is more than just an annoyance—it can lead to increased water bills and potential water damage over time. If you have a bathtub faucet with two handles that is constantly dripping, it likely means that the washers or seats inside the valve are worn out. The good news is that fixing a leaky bathtub faucet is a straightforward process that you can do yourself with a few basic tools. In this comprehensive guide, we’ll walk you through each step to stop that irritating drip and save water.
Why Is Your Bathtub Faucet Leaking?
Before diving into the repair process, it’s essential to understand why your bathtub faucet with two handles is leaking. Here are the most common causes:
- Worn-out washers: Over time, the rubber washers inside the faucet handles can degrade, leading to leaks.
- Damaged valve seats: The valve seats create a seal between the spout and the water supply. Corrosion or debris can prevent a proper seal.
- Loose or damaged stems: If the faucet stem assembly is loose or has worn-out components, water can seep through.
- Mineral buildup: Hard water can cause mineral deposits to form on the faucet parts, preventing a proper seal.
Tools and Materials You’ll Need
Before starting the repair, gather the necessary tools and materials:
- Adjustable wrench
- Phillips and flathead screwdrivers
- Plumber’s grease
- Replacement washers and O-rings
- Replacement valve seats (if needed)
- Plumber’s tape (Teflon tape)
- Needle-nose pliers
- White vinegar (for cleaning mineral deposits)
- Bucket or towel (to catch excess water)
How to Fix a Leaky Bathtub Faucet with Two Handles?
Step 1: Turn Off the Water Supply
Before you start working on the faucet, turn off the water supply to your bathtub. Most homes have a shutoff valve near the tub, but if you can’t find one, turn off the main water supply to your home.
Step 2: Drain the Faucet and Cover the Drain
Once the water is off, open both handles on your bathtub faucet to drain any remaining water. Place a towel or bucket underneath the faucet to catch drips, and cover the bathtub drain with a cloth to prevent losing small parts.
Step 3: Remove the Faucet Handles
Use a flathead screwdriver to pry off the decorative cap on each handle. Underneath, you’ll see a screw securing the handle in place. Use a Phillips screwdriver to remove it. Once the screw is out, gently pull the handle straight off. If the handle is stuck due to mineral buildup, use a handle puller or wiggle it loose gently.
Step 4: Remove the Stem Assembly
With the handle removed, you’ll see the packing nut that holds the stem in place. Use an adjustable wrench to loosen and remove this nut. Once the nut is off, carefully pull out the entire stem assembly using pliers.
Step 5: Inspect and Replace Washers and O-Rings
Examine the stem assembly for signs of wear, such as cracked rubber washers or worn-out O-rings. Replace the washer at the bottom of the stem with a new one that matches the size. If the O-ring is worn, replace it as well.
Apply plumber’s grease to the new washers and O-rings to ensure a tight seal.
Step 6: Check and Replace the Valve Seat (If Necessary)
If replacing the washers doesn’t stop the leak, the valve seat inside the faucet body may be damaged. Use a seat wrench to remove the old valve seat and install a new one.
Step 7: Reassemble the Faucet
Reinsert the stem assembly into the faucet body and tighten the packing nut securely. Reattach the handles and tighten the screws. Snap the decorative caps back into place.
Step 8: Turn On the Water Supply and Test
Turn the water supply back on and test the faucet. Check for any leaks by turning the handles on and off. If there’s no dripping, you’ve successfully fixed your leaky bathtub faucet with two handles!
Preventative Maintenance Tips
To extend the life of your bathtub faucet and prevent future leaks, follow these maintenance tips:
- Regularly inspect washers and O-rings: Check them every few years and replace them as needed.
- Clean mineral deposits: Use white vinegar to remove hard water buildup from faucet parts.
- Avoid overtightening the handles: Turning the handles too forcefully can wear out the washers faster.
- Use high-quality replacement parts: Cheap washers and O-rings may degrade quickly, so opt for durable replacements.
