Stop a faucet stem leak

If a faucet leaks around the handle, you either have a loose packing nut or a bad packing washer. First try tightening the nut with a wrench or pliers. (The size and type of nut varies a bit with faucet styles.) If the nut is tight but the leak persists, shut off the water to the faucet inside the house, remove the faucet handle from the outside faucet and unscrew the nut. You should be able to pull off the old packing washer and take it to a hardware store to find an exact replacement. Older faucets may have a wad of string, called valve packing, instead of a packing washer. If so, pick up new packing (graphite-coated string) at the hardware store, unwind the old packing and wind on the new clockwise. The packing nut should compress it tightly. You may have to wind on one layer, tighten the nut and then repeat the process to fill the space around the stem completely with packing string.
