How to Fix a Bathroom Tub Faucet Leak

A leaky bathroom tub faucet can be a frustrating and wasteful problem. It can not only drive up your water bill, but also cause damage to your bathroom over time. The good news is that many faucet leaks can be fixed with some basic tools and a little bit of know-how. This article will guide you through the common causes of tub faucet leaks and explain the necessary steps to fix them.

Identifying the Source of the Leak

Before attempting any repairs, it is crucial to locate the source of the leak. This will determine the specific repair method required. Common leak locations include:

Spout: Water dripping from the spout indicates a problem with the spout itself or the cartridge.
Handle: A leak from the handle suggests an issue with the stem or packing nut.
Base: Dripping from the base of the faucet points to a worn-out O-ring or washer problem.

Once you've pinpointed the leak's origin, you can gather the necessary tools and materials for the repair.

Repairing a Leaky Spout

If the leak originates from the spout, you will need to replace either the spout itself or the cartridge. While you can try tightening the spout nut, this is usually a temporary fix.

To replace the spout, follow these steps:

Turn off the water supply to the faucet.
Use pliers or a wrench to loosen and remove the decorative cap on the spout.
Use a wrench to loosen and remove the nut that holds the spout to the faucet body.
Carefully pull the spout out of the faucet body.
Install the new spout, ensuring the threads are properly lined up.
Tighten the nut holding the new spout in place.
Replace the decorative cap and turn the water supply back on.

If replacing the spout doesn't solve the leak, the cartridge may be worn out. Here are the steps to replace a cartridge:

Turn off the water supply to the faucet.
Remove the handle (refer to your faucet's instructions if you have a unique handle design).
Using the correct size wrench, loosen and remove the retaining nut that holds the cartridge in place.
Carefully pull the old cartridge out of the body.
Install the new cartridge, ensuring it is properly seated in the body.
Replace the retaining nut and tighten it securely.
Put the handle back on and turn the water supply back on.

Repairing a Leaky Handle

A leaking handle typically indicates a problem with the stem or packing nut.

To repair a leaking handle, follow these steps:

Turn off the water supply to the faucet.
Remove the handle by removing the screw or nut that holds it in place.
Examine the stem for wear or damage. If the stem is worn, it needs to be replaced.
If the stem is intact, check the packing nut. The packing nut is often made of rubber and tends to wear out over time. Replace the packing nut with a new one.
If the packing nut needs to be replaced, you may need to use a tool called a packing nut wrench to access it.
Once the packing nut or stem is replaced, reinstall the handle and turn the water supply back on.

Repairing a Leaky Base

A leak from the base of the faucet usually indicates a worn-out O-ring or washer. To fix this leak, follow these steps:

Turn off the water supply to the faucet.
Remove the faucet body using a wrench to loosen the nuts that attach it to the tub.
Inspect the O-rings and washer for wear or damage.
Replace the damaged components with new ones.
Reinstall the faucet body and tighten the nuts securely.
Turn the water supply back on and check for leaks.
