In this Pool Care Basics video, we discuss how to prime a pool pump. When a pump is priming, it is purging all the air from the system. A fully primed pump is essential in order for the pool system to work properly.
A pump that is not primed will create a host of problems. The heat caused by too much air and not enough water can damage the pump and other equipment. Damaged equipment will prevent the water from circulating and a green pool would quickly follow.
