Our PTMT BALL COCK is a system or machine for filling water tanks, for example, those found in flush toilets, while keeping away from flood and (in case of low water weight) reverse. It comprises of a valve associated with an empty fixed buoy by methods for a switch, mounted close to the highest point of the tank. The PTMT BALL COCK is associated with the approaching water supply, and is opened and shut by the switch which has the buoy mounted on the end. At the point the water level ascents, the model ascends with it; when it ascends to a pre-set level, the component powers the switch to deter the valve and close the water stream .
