I have now been through two Shurflo pumps with the same problem. The literature to which TC Bear linked was helpful, but even more helpful was talking with one of the customer service folks at Pentair/Shurflo, who walked me through an adjustment that lowers the shutoff point. This didn't fix the problem. When I talked with him today, he said that, yes, there's a known problem with the check valve on these pumps, and I should send it back and get another one.
Frustrating. Is there a pump manufacturer I should be considering instead of Pentair/Shurflo? I looked online, and a pump that was recommended as "best choice" seems to have the same problem.
Is it feasible to install a check valve upstream from the pump and not rely on the pump's check valve?

No, not IMO. an external check valve cannot compensate for the internal check valve in the pump head. I would do as stated, return it to the mfgr. for replacement. In the meantime buy a new one from Amazon and try it, their liberal return policy means you can get your money back later.
