My Mom's cat - The Cranker - will only drink from the bathroom faucet. Ok, so every now and then he'll concent to the bathtub faucet being turned on, but mostly it's the bathroom sink or nothing.

My mom and dad were going out of town this weekend, and my brother wasn't going to be around either, so my mom said she'd probably have to leave a bowl of water in the sink for the Cranker or he'd have no water.....but it'll be interesting to hear if he actually drank out of the bowl or not.
