Abstract
A toilet fill valve having a mechanism for preventing leakage from a tank of the toilet between flush cycles. The mechanism includes links that are normally locked to prevent the fill valve from opening. The links are operatively connected to a handle of the toilet such that the links are unlocked and allow the fill valve to open only when the handle of the toilet is purposely operated to initiate a flush cycle. Otherwise, the links do not allow the fill valve to open even if water leaks from the tank and causes a float of the fill valve to be lowered.
