That's essentially what I do, very low risk, easy to use, and not many parts.
To cause a flood the solenoid would need to fail on AND the float valve would need to fail at the same time. That would still only cause a 15 minute fail, the timer would need to fail as well to lengthen that.
Cycling my RO system just means a few extra automatic membrane rises per day.
