At first, my keeper was working fine, but for the past few days I've been having difficulties. If I keep it in for more than an hour or so, it rides up so high I can barely reach it to take it out. Even when I do reach it, the suction is so strong that it takes me a good ten minutes to take it out. I'm scared to use it again, it would be horribly embarassing to ask my fiancee to go on a search and rescue mission. What the hell am I doing wrong? Is there something I can do to lessen the suction?
