steelerguy pretty much got it right. It is called the over the top method. Don't need to drill your sump that way. Just have to prime the pipes once and the water stays in them. Think the longest that I've had the main pump off was 4 hours and it started right back up.
You prime it by putting a "T" in the return line with a screw cap fitting (( See picture )). Put a ball valve below it in the sump, close it off and fill with water. When the line is all full of water screw the cap back on. Turn on the pump, open the ball valve and away you go. Sounds more complex then it really is. 2 out of 3 of my sumps are that way, and have been running for 4+ years without issue.
BTW -- it is a T2.
