Leak is occurring around the handle that turns the water on and off.

If the leak's coming from the nut under the handle and leaking out past the stem then turn the faucet on until the leak starts. Now tighten the nut ( It's called "The Bonnet Packing Nut") down until the leak stops. CAREFUL! Don't over tighten. Stop tightening when the leak stops. Did that fix it? Good luck. Tom
