I made this DIY water sensor with just a couple nails, solder, and some wire. Works great, even with fresh water. It acts as a switch, open when dry, and closed when wet. Then you need a device, like a controller (I use my Apex), that will turn a pump switch off, when this is on. Or you could build a relay that trips a switch on and off. Lots of ways to do it...
