This any easy task most homeowners can handle. With a few simple tools and only a couple of steps you can repair you leaky hose faucet.
1: Turn off the water to the faucet. If there is no dedicated valve the water supply line, turn off the main water valve for the house. 2: Remove the screw holding the handle with a Phillips screwdriver. Pull the handle off. 3: old the faucet body steady with one pair of adjustable pliers while you use another pair to unscrew the packing nut just under the handle. Remove the nut, then reattach the handle and use it to pull the valve stem straight out. Most frost-free stems are 24 inches long, so keep pulling until it's all the way out. 4: Remove the screw holding the seat washer and take out the washers. If the stem has an O-ring, cut it off with a utility knife. Rub a little plumber's grease on a replacement O-ring and slide it into place. Replace the old seat washer with a new one and tighten the screw back on to hold it. 5: Push the valve stem all the way back into the valve seat. Remove the handle and screw on the packing nut. Tighten it with adjustable pliers while holding the faucet steady with the other pair of pliers. 6: Replace the handle and turn on the water. Open the faucet and then close it to check for leaks.
