New to this forum and thanks for reading my post. Our catalina 30 tall ship has just come out of winter storage and we are having difficulty purging the air from the water. In other words, the water only spurts out at intervals. You can hear that water has air in it. Water tank is full. And we have cleaned all of it out. It does need a new water filter, we believe. Any ideas how to purge this air from our water would be greatly appreciated. My husband and i have worked on it to no avail for several weekends. thanks so much!
