Justin you used sump pumps right off the shelf from HD or Lowes? I've heard those have oil in them, though maybe not all do? If I was in that situation I think I'd do something similar, though I think I'd get a regular aquarium pump that can handle some head, then set it up with a few float valves. Have a pair to turn the pump on when the water gets too high, one to do that plus a backup, then another and a backup to turn the pump off when the water gets low.
That said, in the event of a power outage you'll still need to make sure the sump can handle all of the water, a good deal above the pump turning on mark since you'll get a lot of extra water.
Correct, I use the sump pumps straight off of the shelf. The oil is of no concern as this is just waste effluent from the drip system. None of this water ever touches a tank again. I thought about going aquarium pumps but am too attracted to a Home Depot run and a 4 minute swap out when the pump dies. I have the spare pump in the shed but have never used it. I have my system dialed in so there are no overflows etc.. but one could easily set it up wrong if they didn't have the experience.
