Before You Begin
Place your hand under the drip from the faucet.
If the water is warm, the leak is most likely on the hot side of the faucet.
If the water is cold, the leak is most likely on the cold side.

No matter which valve wears out quicker, many people choose to replace both valves at the same time.
The valve may have a small football-shaped handle or a lever or knob.
Turn the handle clockwise until it stops.

Remove the Stem
Note the position of the stem before removing it.
You must reinstall it in exactly the same position for the faucet to work properly.
It might be helpful to take a photo of the stem for reference.
The Spruce / Kevin Norris
Remove the stem by pulling it straight up and out of its housing.
Use pliers, if necessary, gripping just the spindle at the top of the stem.
The valve seat is a small, black, rubber cap with a hole in the top.

Sitting inside and below the seat is a small metal spring.
Note the spring’s orientation inside the valve seat.
You must set up the new spring and seat with the same orientation.

Use the screwdriver or wrench to guide the spring and seat into the hole in the stem housing.
They must fit all the way down into the hole.
Remove the screwdriver or wrench and confirm the valve seat is positioned properly.

Fit the stem into its housing, aligning the tabs on the stem with the slots in the housing.
Push the stem all the way down until it stops.
Reinstall the bonnet nut and tighten it carefully with pliers or an adjustable wrench.

Check for leaks around the faucet stem.
