WELL IT'S JUST A DRAIN. IT WORKS. HOWEVER, IT WOULD BE REALLY REALLY NICE IF PLUMBERS OR SELLERS OF FAUCETS WOULD TELL TO BUY THESE ALONG WITH THE FAUCET. ME- I FOUND OUT THE HARD WAY AND IT HAS DELAYED THE COMPLETION OF MY BATHROOM. I ALSO YELLED AT THE RECEPTIONIST AT THE PLUMBING SHOP I USED BECUASE OF THIS. I AM NOT PROUD.
