I can't get a pump to prime. It is a 1/2 horsepower (Wayne) Sallow Well Pump. I hvae it mounted on a small tank that has a bladder inside. There is water in the well . . . about 5' below surface. The check valve is ok. I even hooked a garden hose to the spigot to make sure it got enough water. Still no dice! The tank has about 15 pounds air pressure. What am I doing wrong.
I await your expert input.
Thanks, Tom
