Redundancy and fool proof failsafes are the only way to avoid disaster.

The limiting the amount of water in the reservoir is the safest.

Electronic ato can always fail. Nature of the beast.

Gravity fed can also fail... Something gets stuck on the float, etc.

I've had issues with both methods.

I've only had a near hobby ending experience with my gravity fed. (Mind you it was with a large reservoir going through a kalk reactor)
