There is a way to get essentially all of the benefits of AutoPots with zero chance of ever having a flood, and maybe other benefits too. Take full manual control of feeding. Do not use a reservoir, plastic tubing, the AutoValves, etc. -- Simply regularly manually refill each AutoPot's reservoir as you see fit. I did that for multiple grows, and considered the results just as good as using the 'automated' reservoir/tubing/AutoValves system.
Manual AutoPot feeding also allows much more control of feeding, such as I would often add a day without any feed/water, to allow the coco/perlite to dry out a little bit before it gets saturated again.
I also much preferred feeding freshly-mixed feed, with reservoirs always turning nasty on me. I never saw any upsides in feeding days old feed. Freshly-mixed feeding also allows much broader freedom in use of supplements -- organics, even gunky carbohydrates, can be added with no concerns about tubing or valves clogging. And manual feeding allows much more customization for each plant - different feeds; supplements can be added individually, etc.
Otherwise, what clinched, pushed my decision, to go manual feeding was that I found it overall simpler and less work than messing with the reservoir/tubing/AutoValves.
