Just an update on my setup. Since I'll be running well water to the system, I need the ability to stop the water supply in the event of a runoff. Our friend Rives pointed me to an auto shut off valve with a water sensor. I'm still waiting on blumat materials, but was able to test the shutoff.
Very simple Chinese device, but was only $150. Cheap insurance. I can connect standard garden hose fittings to and from it. Has an audible alarm and a connection that allows an X-10 device or such to be connected. These other devices can phone you, etc. I will be looking into that also.
Functionally, it looks good. Very sensitive. One drop and it triggers the alarm. Just like in Mission Impossible. Ball valves close and lock until you press the OPEN button. Worst case scenario is the plants dry out after a few days. Better than a flood.
