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...

That looks like a sweet simple idea that could sit at the top of a tank or something like it. Do you have a pic of it in place?

I've got my overflow system outside testing and it's been running for 3 days straight. The only problem is the crap that builds up on the ABS pipe, the slits I cut. It captures everything. What can I do to solve that?
