I really like my XP 2 except for one problem..I have a heck of a time priming it if it looses it's prime. I have to have hubby help me, and one of us pours the water in the tubing at the cap on the intake, and the other works the pump. After much wailing, gnashing of teeth and pulling of hair..on my part..it finally goes. He's pretty calm about it..lol. It drives me nuts. Any hints..tips..something I'm missing?
