I still use on one of my sump's the first float valve I ever bought for a tank more than ten years ago. It's been in continuous use as an ATO in the last ten years without a single failure. Best $8 I ever spent in the hobby. I bet most $200 switch and pump style ATO's cannot claim that kind of uptime yet. Sometimes simplicity is just fine.
