Full Answer

The bottom opening of the valve should first be screwed on to the kayak. The top valve is opened and used to pump air inside the desired object. Once the boat or mattress is filled with the correct amount of air, the upper valve is then closed. Air can be released from the object by unscrewing the bottom or base valve.
