Step-by-Step Guide

   Step 1: Purchase a replacement parts kit from a reputable hardware store

   The kit Home Depot sells is comprehensive in that it includes all of the washers and gaskets, springs, a new ball, and the plastic inset piece for the top of the assembly.

   Step 2: such as Home Depot.

   I say carefully because these are some of the least used valves in your home and they could be corroded making them difficult to turn.
   
   NEVER use excessive force, the valves are likely made of brass and brass is softer than steel.
   
   Turn on the faucet and make sure the water is turned off. , Lift the handle off of the faucet assemble and set aside. , This threaded ring has four slots cut in it.
   
   Push in a notch with a screwdriver to relieve the force on the internal parts.
   
   You may need to tap the screwdriver gently with a hammer to get things moving. , You may need to use Channel-Lock pliers to get things moving.
   
   Set aside. , This disc should lift off with a black rubber gasket.
   
   This gasket is what keeps the faucet from leaking around the top chrome-dome when the water is turned on. , Please note the orientation of the ball, cut into one side of the ball is a slot that rides on a stud inside the socket. , These are the washers that keep the water from leaking when the faucet is off.
   
   These can be removed by gently prying them out with a small, flat-tipped screwdriver.
   
   Also, be sure to remove the spring. , The large end of springs go in first and the seats (the rubber things) slip down over the spring.
   
   You should press firmly to seat the washer almost flush with the bottom of the socket.
   
   Wipe a small amount of silicon grease onto the rubber washer.
   
   This will help keep things lubricated through the life of the washer. ,,, These should be removed and replaced with the corresponding washers from the parts kit.
   
   Again, apply a small amount of silicon grease to keep things rotating smoothly. , Be sure to keep the cylinder upright at the beginning, this makes it easier to get it started. , You shouldn't have to force the ball into the socket. , Keep in mind that the disc is keyed with a slot on the left side of the upright cylinder. , This will make it moderately easier to re-install the chrome-dome. , This should prove to be the most difficult part of the procedure.
   
   Remember that all of the washers, gaskets and springs are new and there is a lot less leeway in the fit of things.
   
   You may have to press down on the plastic disc with a pair of needle-nosed pliers to get enough room to get the chrome-dome threads started. , Remember that you can loosen the plastic ring inset if you need to get that last 1/4 turn. , If you get things too tight you will cause things to wear quicker than normal and you'll need to do this whole procedure again sooner than not. ,,, Start out with the water on cold and on with about half the maximum pressure.
   
   If things look OK with the half pressure then turn the cold water on all the way.
   
   Again, check for leaks.
   
   Once you're sure things are OK, turn on the hot water. ,
