I know this is an old subject but I'm trying to tighten up the handle on my mother in laws Water Ridge kitchen faucet, 205674. It just flops around. How do I get to the screw to tighten the handle. She doesn't want to replace the whole thing, and I would be the one doing it and really doesn't want to spend the time under her sink. She is fighting bone cancer right now so we're trying to help her in everyway we can. The faucet was already in the kitchen when she purchased the home. Thanks, TJ
