I'm installing a new sink (Vapsint brand) and stuck trying to figure out wh y I have a leak at the spray hose connection. It's the kind of connection with a plastic piece at the end of the hose (with a button on either side w hich I don't know what the purpose is). The plastic piece connects to a me tal screw on piece at the bottom of the faucet, with a small rubber o-ring in between. The leak seems to be coming out of the top of the connection. I did use pipe thread tape. Any suggestions what I'm doing wrong here?
Thanks!
