Question: My 2 handle bathroom faucet is leaking. The faucet is a Delta Bathroom Faucet and it has two knobs or handles. When I turn on the cold water handle, water leaks from under the handle.

If the cold water handle or knob on my bathroom faucet leaks when turned on, what is the easiest way to fix it? I want to fix it without spending much money or buying a new bathroom faucet? Can you tell me how to take it apart and what parts I may need to fix or replace?
