How to Replace the Valve Stem on a Faucet
The valve stem on your faucet is the part that controls the flow of water into the spout. The faucet handle is attached to the valve stem so that when you turn the faucet handle, you also turn the stem. A washer at the bottom of the stem raises or lowers, depending on which way the handle is turned, to cut off the water. These stems can wear out, causing leaks. In that case, you should replace the valve stem on your faucet as soon as you can. Does this Spark an idea?
