Based on some conversations at the meeting today in Marlboro and the unfortunate flooding that has happened to others, here are links to very inexpensive water alarms
They are sold by both Lowes and Home Depot. Lowes carry multiple versions and at less than $12 a pop there isn't excuse to some piece of mind. Either case they are 100 deceble alarms so you can't miss them even if you sleep like a rock. They are also EXTREMELY sensitive, with as little as a few drops of water detected. Place one under your tank, on the floor under your sump, and any lower point where water can flow. Hang it in your RO water container while you fill it to remind you when it got to the top before you did, etc..
