How to Repair a Leaky Compression Faucet
Most faucets in the home are compression faucets. The handles open the water supply by releasing compression on a rubber washer and stop the flow of water by compressing the washer. When the washer is defective, the faucet will leak. To repair a leaky compression faucet you will need to replace the washer and possibly dress the faucet seat. Does this Spark an idea?

Unscrew the packing nut that attaches to the faucet stem with a pair of pliers. Place the handle back on the faucet stem and unscrew the stem from the faucet body. Turn the stem upside down and examine the washer on the end of the stem. The washer will probably have dry rot, cracks or other damage.

Remove the brass screw that secures the washer to the stem with a Phillips screwdriver. Take the washer with you to a hardware store and purchase a replacement that matches the current washer exactly. It is a good idea to replace the washers on both handles at the same time. If you do not already own one, purchase a valve seat dresser as well.
