Why Is My Bathtub Faucet Leaking? Causes & Quick Fixes

Noticing your bathtub faucet leaking? Don’t panic — this is a common issue in many bathrooms. The good news is that most leaks can be fixed without replacing the entire faucet. In this guide, we’ll explain why leaks happen and how to fix a bathtub faucet quickly.

A leaking faucet isn’t just annoying — it also wastes water and increases your utility bill. With the right tools and knowledge, you can stop the drip and extend the life of your faucet. Let’s dive into the causes and quick fixes.

Common Causes of a Bathtub Faucet Leak

There are several reasons why your faucet may be leaking:

- Worn-out washers or O-rings: These small parts often degrade over time and cause drips.
- Corroded valve seat: When the valve seat becomes damaged, it prevents a proper seal.
- Loose parts: Nuts, screws, or cartridges may loosen with daily use.
- High water pressure: Excessive pressure can force water through even small gaps.
- Damaged cartridge or diverter: Especially common in single-handle faucets.

Tools You’ll Need to Fix a Bathtub Faucet

Before starting your repair, prepare these tools:

- Adjustable wrench
- Screwdriver set
- Replacement washers or cartridge
- Plumber’s (Teflon) tape
- Cleaning cloths and bucket

Step-by-Step Guide: How to Fix a Bathtub Faucet Leak

1. Turn off the water supply. Use the bathroom shut-off valve or main water line.

2. Drain remaining water. Open the faucet to release any pressure.

3. Disassemble the faucet. Remove the handle and access the cartridge or washers.

4. Inspect components. Look for worn washers, O-rings, or damaged cartridges.

5. Replace faulty parts. Insert new washers, O-rings, or a replacement cartridge.

6. Reassemble and test. Tighten connections, turn the water back on, and check for leaks.

DIY Tips for Preventing Future Leaks

- Don’t over-tighten handles — it wears out washers faster.
- Clean mineral buildup around the faucet regularly.
- Replace small parts (washers, cartridges) every few years.
- If leaks continue, consider a full faucet replacement.
