Our faucet handle has been leaking and we thought this would be a project we could handle ourselves. We watched some "how to" youtube videos and were able to get the little screw out and thought that the handle should just pull up and off. We also tried spinning the handles clockwise and put WD40 in the little screw holes. We tried putting a flat head screwdriver between the handle and the seat (is that what it is called?), and it does wiggle a tiny bit but is still not budging. They have been there for probably 15+ years. Any help would be greatly appreciated. Thank you!
