re: Leaky Bath Faucet - Attempt to Repair or Call a Plumber?

Pretty easy to do but does require a few specialty tools to pull the valve stems out and either change out the parts or simply buy new stems and replace the old ones. It takes a pretty deep socket type tool to reach into the faucet body to access the stems and any big box store will have that set of stem remover tools.

Depending on what faucet you have, you may be able to find new stems at a big box store, but it is best to take the stems to a real plumbing supply place so you can get exactly what you need.

First things first is to turn off the water coming into the house or once you remove the stems you're shooting water everywhere.
