Hi Guys! I have a small leak under my bathroom sink vanity. The leak is so minute that I can't tell where the leak is coming from just by looking but it is enough to prevent the use of the base cabinet as storage for such things as toilet paper. (I've had to pull everything out from under the sink & put it all in a box until I can fix the problem.) I wiped down all of the pipes & looked later to see if any were wet. They weren't so I'm fairly certain that the leak isn't coming from one of the pipes or the joints. I've looked for green corrosion but there is none. I think it may be coming from one of the water lines that connects to the faucet handles or even the lift rod, if that's possible, but I just don't know. And, I don't know how I can determine where that darn leak is coming from so I need your HELP & ADVICE PLEASE to find this leak!! P.S. Just in case you couldn't tell by my description of my problem, I'm a do-it-yourself female that can't afford a plumber. Thanks guys for your time & consideration.
