A21.The valve has a special pushpin inside. This pushpin has two positions, both up and down. When it is pressed in the down position, air will escape. If you turn the pushpin in any direction it will pop up. This will lock air inside and prevent it from escaping through the valve. Before inserting the air pump tube into the valve, please make sure that the pushpin is in the upper, popped up position. Once the pin is in the "popped up" position, insert the air pump tube into the valve and inflate the boat until it becomes hard. Once you remove the air pump, air will seal the valve and will no longer escape. If you would like to deflate the boat later on, press down on the pushpin and turn it in any direction until it stays in the pressed down position. Air will immediately escape from the tubes through the valve.
