I agree if it depends on a pump like an aqualifter to restart siphon.
I its a utube overflow, you should not have failure for any reason.
Going on 4 years with my current DIY overflow never, ever failing.
People who say it's an accident waiting to happen are just ignorant on this subject...likely from lack of experience.
What kind of external overflow did you use?
If it happened once, it will happen again if you dont figure out why and how.
