Also, if the float switch in the reservoir fails, you have freshwater all over your main floor. Neither scenario would please your wife or you.
I really like Reef Pilot's setup for failsafe, foolproof ATO system, cause having it timed (5 min every 6 hours) will really minimize any excessive RODI water dumpage, either into the display/sump or your floors.

With my set up, both the solenoid (in the open position) and the float valve would have to fail before I could have an overflow. While theoretically possible, the mathematical probability of that is very, very minuscule. Especially, since the solenoid is spring loaded to close, and needs power to open. The much more likely failure is for the solenoid failing to open, which of course can't produce a flood.
