1. Tighten the packing nut. This nut is behind the handle of the shutoff valve. Use a pair of groove joint pliers to tighten the nut. Cover the ends of the pliers with masking tape to prevent damage. Turn the nut clockwise one-eighth of a turn. Inspect the line for leaks.
2. Disassemble the plumbing valve. Turn off the water supply to the entire house. Turn on the sink or flush the toilet to remove water remaining in the lines. Unscrew the handle of the valve with a screwdriver. Remove the packing but with a pair of groove joint pliers. Cover the ends of the pliers with masking tape to avoid damaging the nut. Remove the threaded valve stem.
3. Clean the washers. Remove the neoprene washers and use a dry cloth to thoroughly clean them. Bend and flex the washers.
4. Reassemble the plumbing valve. Place the threaded valve system and washers back into place. Use a screwdriver to attach the handle.
5. Inspect the line. Turn the water supply back on and check the valve for leaks. If the valve continues to leak, you will need to replace the plumbing valve.
6. Turn off the main water supply and turn on the sink or flush the toilet to remove the water remaining in the lines. Unscrew the packing nut and remove the entire valve. Place a new valve on the line and tighten the packing nut with a pair of groove joint pliers. Cover the ends with masking tape. Turn the water supply back on and inspect for leaks.
