OK, Thats a good method of priming. They are using a vacuum pump to remove all the air, but there is a check valve in the line so no air can flow back into the system there.

BUT, what he had there still will drain down untill the inlet becomes uncovered. It will not restart after that.

Try what I said with getting the siphon going with cap installed on your T. Then after 15 seconds, remove cap.

And I just remembered, If you put another T in where I drew, your going to have to plug both the inlet and the outlet to the sump in order to prime it. Might be just better to do the remove cap method. Priming and making sure there is no air in the line will be difficult
