First you need to turn off water to the faulty valve. Then you need to
remove the valve stem complete with handle preferably. Then take the stem to
the plumbing supply, HD, or hardware store and ask for replacement seals
which match your old ones. The seals get old, dry rot, or become clogged
with rust, preventing them from seating completely.
If the inside of the valve body is crusty, ask for a seating tool which
will match your seat size. If the corrosion isn't bad, just replace the
seals and be done with it. You will need to remove the stem and take it with
you to match the seals with the correct size and shape. Often a piece of
rust will get in there and prevent the seat from seating completely.
