Please help. I have most of a bottom mounted faucet deinstalled but I can't figure out how to remove the handles to get to the eschucheon. I've tried pulling, unscrewing, there are no screws visible and it's all one piece. Since the faucet is old and doesn't work properly (I'm throwing it away) can I cut the stem pipe (looks like it's copper)? If so, which tool should I use?
