Any larger submersible powerhead to overcome the head height. I ran a pump into a couple of irrigation drippers. That prevented the pump from pushing too much water into the system too fast. Even if a float switch stuck on, the pump just couldn't push that much water through the drippers.
The pump could be stuck on for days before you begin to notice that the water level is increasing.
