How to Repair a Faucet Stem
A worn faucet stem is frequently the cause of a leaking faucet. To fix the problem you can replace the leaky faucet with a new one, or you could replace the entire faucet stem with another stem if it is available. However, it is better to repair or rebuild the faucet stem on your existing faucet. Does this Spark an idea?

If it has one, pry the faucet cap off the faucet handle with a thin blade screwdriver. Remove the Phillips-head screw beneath the cap with a Phillips-head screwdriver. Gently pull the handle with a back-and-forth motion until it comes out. Unscrew the packing nut with an adjustable wrench and take out the entire stem assembly by using a pair of needle-nose pliers.

Fasten the new replacement washer (or old washer if reusable) with the new brass screw. Remove the valve seat using a seat wrench and check to see if it is damaged (hole in the center with no slots) and replace if needed. If it's not damaged, seal in the piece with pipe joint compound. Reassemble the unit, reversing the steps used to take it apart.
