auto topoff question

[SPS20]

I always found it odd that Tunze uses a floatie for backup, have you ever wondered about that as well?

 

Well, even with an optical sensor, I suppose it is possible something could go wrong, so the float is just there to force the pump to turn off in the event that the optical sensor fails.

 

However, I have never even heard of an Osmolator's optical sensor failing. (I tried to find complaints online, and the only complaint i found repeated over and over was the badly translated directions. Yes, the instructions are absolutely terrible, but if you can figure them out, its a great system. I actually found it easier to read them in german than in english, and my german isn't all that great.)
