I had the same thing happen to my Bosworth brand Y-valve. Unfortunately the whole valve needed to be replaced as a result. Rinse a lot of fresh water through the system including down the tank discharge before you dismantle the current valve. In the future, consider using a small amount of vegetable oil on occasion to lubricate the Y-valve. I dribbled the oil down the tank discharge.
