Faucet Sounds Like Man Moaning [VIDEO]
Turn up the volume.
A faucet, when open, sounds like a man moaning. Now, I am no plumber, thus I don't know what is causing this. Could it be air in the pipe? Perhaps.
However, I'd encourage you to play this video really loud at work and watch what people do. They will never believe that you are watching a faucet being opened and closed.
This is so weird.
