Why Your Bathtub Faucet Drips And How To Fix It
What To Know
- The washer, a small rubber or plastic seal, sits between the faucet handle and the stem.

- If the stem becomes damaged or corroded, it can prevent the faucet from closing properly, resulting in a drip.
A dripping bathtub faucet is more than just an annoyance; it can waste hundreds of gallons of water per year and increase your utility bills. Understanding the causes of a dripping faucet is crucial for finding an effective solution. In this comprehensive guide, we will delve into the reasons why bathtub faucets drip and provide expert advice on how to fix them.
Causes of a Dripping Bathtub Faucet
1. Worn-Out Washer
The washer, a small rubber or plastic seal, sits between the faucet handle and the stem. Over time, the washer can wear out, crack, or become dislodged, allowing water to leak through.
2. Loose Handle Screw
The handle screw connects the handle to the stem. If the screw becomes loose, it can cause the handle to wobble, which in turn can damage the washer or cause the faucet to drip.
3. Damaged Stem
The stem is the part of the faucet that controls the flow of water. If the stem becomes damaged or corroded, it can prevent the faucet from closing properly, resulting in a drip.
4. Faulty Cartridge
Some faucets use a cartridge instead of a washer and stem. A faulty cartridge can cause a leak if it becomes worn or clogged with debris.
5. Mineral Buildup
Hard water can leave mineral deposits on the faucet’s parts, which can interfere with the proper functioning of the washer or cartridge.
6. Corroded Valve Seat
The valve seat is the surface that the washer or cartridge seals against. If the valve seat becomes corroded or damaged, it can prevent the faucet from closing completely.
7. High Water Pressure
Excessive water pressure can put strain on the faucet’s components, causing them to leak or fail prematurely.
How to Fix a Dripping Bathtub Faucet
1. Check the Handle Screw
First, try tightening the handle screw. If the screw is loose, it may be enough to stop the leak.
2. Replace the Washer
If tightening the handle screw doesn‘t work, you may need to replace the washer. This is a relatively simple repair that can be done with a few basic tools.
3. Replace the Stem
If the washer is not the culprit, the problem may be with the stem. Replacing the stem is a more complex repair, but it is still possible for a DIYer with some plumbing experience.
4. Replace the Cartridge
If your faucet uses a cartridge, you may need to replace it. This is a more involved repair, but it is still possible to do it yourself if you are comfortable working with plumbing.
5. Clean the Mineral Buildup
If mineral buildup is causing the leak, you can try cleaning it with a vinegar solution. Soak the affected parts in vinegar for a few hours, then scrub them clean with a soft brush.
6. Repair the Corroded Valve Seat
If the valve seat is corroded, you may be able to repair it with a valve seat wrench. This is a specialized tool that is used to grind down the corroded surface and restore its sealing ability.
7. Reduce Water Pressure
If the water pressure is too high, you may need to install a water pressure regulator. This device will reduce the water pressure throughout your home, which can help prevent leaks and other plumbing problems.
How to Prevent Bathtub Faucet Drips
1. Use a Soft Touch
Avoid turning the faucet handle too tightly. Excessive force can damage the washer or other components.
2. Clean the Faucet Regularly
Cleaning the faucet regularly will help remove mineral buildup and other debris that can cause leaks.
3. Check the Water Pressure
Have your water pressure checked periodically. High water pressure can put strain on your plumbing system and lead to leaks.
4. Install a Water Softener
If you have hard water, installing a water softener can help reduce mineral buildup and extend the life of your faucets.
