The seals
Faucets use washers, O-rings, and cartridges to seal. When one wears, the faucet drips or leaks at the base.
The diagnosis
A spout drip is usually a cartridge or washer; a base leak is an O-ring; a handle leak is a stem seal.
The fix
Shut off the water, open the faucet, and replace the worn seal with the matching part.
