Hi All,
Hypothetically, is it possible that a maxijet powerhead that has run dry could start a fire?

I would be running a maxijet 400 or 600 with a timed topoff. I will be using a digital timer to run the powerhead for one minute each night. Worst case scenario, if the pump ran dry for 2 days what would happen? Just a dead powerhead? Thanks alot for your thoughts!
Bud
