Abstract
A major water leak prevention apparatus for a water inlet valve, in which a water receptacle tray is mounted on a water inlet valve body and includes an overflow port. The water receptacle tray has a bottom in which an opening is formed. A counterweight float is mounted on the water inlet valve body and includes a water compartment and a buoyance compartment arranged at a lower end of the water inlet valve body. The bottom opening of the water receptacle tray is connected via a passageway pipe to the counterweight float. The water compartment selectively blocks a lower end opening of the passageway pipe or opens the lower end opening of the passageway pipe. This arrangement helps stop water ingress through the water inlet valve when major water leakage occurs in a water tank.
