2. The water rises upward and antlers the boiler return trap, filling it and raising the float which operates the valve mechanism. 3. When the trap is full, the weights that operate the valve mechanism are tripped, vent valve is closed and steam valve is opened, admitting steam that is at boiler pressure to the trap.
