used to have a gravity fed system with a float valve that failed once a year. I'd replace it and it would be good for another year. Finally when I set up my most recent tank I decided to look into a float switch. Turns out one came with my controller so I set that up. Its failed on me a couple of times (small brittle stars get into the floating part of the switch and jam it) but my topoff tank is small enough and the main tank large enough that if the whole topoff tank ends up in the sump, its not a huge deal.
