Diagnosing the Leak

Before starting the repair, it is essential to identify the source of the leak. Here are some common causes of a leaky single-handle bathtub faucet:

Worn or damaged cartridge
Loose handle
Cracked or broken seals
Faulty aerator

To determine the source of the leak, you can:

Check the handle: If the handle is loose or wobbly, it may indicate a loose cartridge or handle set.
Examine the aerator: A clogged or damaged aerator can cause the water to spray or leak.
Remove the faucet handle: Once the handle is removed, you can check the cartridge and seals for damage or wear.

Tools and Materials Required

Once you have diagnosed the leak, gather the necessary tools and materials for the repair:

Adjustable wrench
Allen wrench or hex key
Phillips head screwdriver
New cartridge or handle set (if needed)
Plumber's tape
Replacement seals (if needed)

Turn off the water supply: Locate the water supply valves beneath the sink and turn off both the hot and cold water valves.
Remove the faucet handle: Using an Allen wrench or hex key, loosen and remove the screw holding the handle in place. Then, gently pull the handle straight up to remove it.
Remove the cartridge: Once the handle is removed, you will see the cartridge. Use an adjustable wrench to loosen and remove the cartridge from the faucet body.
