Drip system - looking for a specific thread

[Clay]

I'm looking for a specific thread on a drip system. The thread had a video and a switch that would close in the event of a power outage. I can't seem to find it, so I was hoping that someone would have a link handy. I'm trying to get all of my project ideas together for the new tank that's going into the wall.

Thanks in advance!
