Sorry to hear about your trouble. A "drip" doesn't cause your pump to kick on 3X an hour....that's a sizable leak. Some of the Grundfos pumps have built in cycle protection and you have to leave the power off for a number of minutes before it will reset. I don't deal with them often so I can't really remember the details.
Is that a filter between the pump and tank? Hard to tell from your pic. Never put a filter between the pump and tank.
Good Luck, I hope your well guy makes it right if the pump failed prematurely.
