How to Fix a Leaking Bathtub Faucet: A Step-by-Step Guide

What Type of Leak in Bathtub Faucet?

Understanding the source of the leak is crucial:

• Dripping from spout: Likely due to a worn washer or cartridge.
• Leaking from handle: Possibly a faulty O-ring.
• Water under handles: Could be a loose valve assembly.

🛠️ Tools Needed

Before you begin, gather the following tools:

• Adjustable wrench
• Phillips/flathead screwdriver
• Replacement parts (washers, O-rings, cartridge)
• Plumber’s tape (Teflon tape)
• Vinegar (for mineral deposits)

⏳ 10-Minute Fix for Most Leaks

1. Turn Off Water Supply

• Locate shutoff valves under the tub or in the basement.
• Turn valves clockwise to stop water flow.
• No valves? Shut off the main house supply.

2. Remove Handle

• Pry off the decorative cap with a screwdriver.
• Unscrew the handle screw (may be hidden under the cap).
• Gently wiggle the handle off; tap with a wrench if stuck.

3. Fix Based on Leak Type

A. Dripping Spout (Worn Washer/Cartridge)

1. Remove the retaining nut with a wrench.
2. Pull out the cartridge/stem assembly.
3. Replace the rubber washer or the entire cartridge if corroded.

B. Leaking Handle (Faulty O-Ring)

1. Locate the O-ring on the valve stem.
2. Pry off the old ring with a screwdriver.
3. Wrap the new O-ring with plumber’s tape.

C. Water Behind Handle (Loose Valve)

1. Tighten the packing nut with a wrench (avoid overtightening).
2. Add plumber’s tape to the threads.

4. Reassemble & Test

• Reinstall parts in reverse order.
• Turn the water back on slowly.
• Check for leaks.

💡 Pro Tips

• Match replacement parts: Bring old parts to the hardware store.
• Soak crusty parts in vinegar: Overnight soaking can remove mineral buildup.
• Upgrade to a ceramic cartridge: For a longer-lasting fix.

⚠️ When to Call a Plumber
