After you have the stems out you should be able to find the washer on the "inside" end. If it is nicked, torn or brittle it is likely the cause of your drip. Even if it looks brand new, go ahead and replace it. You've already come this far. You can get replacement washers at almost any hardware store. Sometimes you may want to replace the whole stem, especially if the handle end is stripped out. It's best to just take the stem with you to the store and see if you can match it up.

Here are some general cautions. Do not begin jobs on holidays, weekends, or at times when plumbers raise their rates or are difficult to reach. Do start early leaving plenty of daylight to call a plumber if something goes wrong. Study the situation carefully. Think about what might happen if something suddenly broke and what the effects would be. Old corroded copper tubing might break in the wall when you are wrenching an angle stop that supplies the water line repair to your toilet. A flood in the wall could be costly. If the angle stop, on the other hand, is new and shuts off easily and you have another toilet in the house then it might make sense to repair the toilet yourself. Be honest, too. Are you handy with tools? Did you do well in shop classes in school?
