Narrative:

It was reported to me by a flight attendant that the aft lavatory sink drain was plugged. I started deferral 3820P. As I was accomplishing the maintenance items to complete the deferral, another flight attendant reported that she thought the water faucet was running too long or sticking open. At that point I decided to inoperative the lavatory using MEL 3830K, so a more thorough inspection could be accomplished. I checked for leaks. None found. I then determined the faucet function was normal and I closed and locked the door and installed a 'do not use' placard. I then left the aircraft to check the MEL to see what maintenance items I had to accomplish to comply with the MEL. When I returned, the plane had been dispatched. I then contacted the line maintenance controller and advised him of the situation. He told me he would contact the crew and have the trip return to the gate. After several mins I called the line maintenance controller for an update and he said the plane was airborne.
