I looked up the patent description of the sensor to see how it is supposed to work.

The opening at the bottom of the clear tube is immersed in the reservoir and as the water rises, it compresses the air in the tube, until eventually this closes a diaphragm at the top and shuts the water off.
I have to presume that Earthbox manufactured the system properly so that this will happen. I am going to try immersing my filler arrangement in a pot of water so I can watch it work.
Something is very very wrong here. I have two of them and they both do the same thing.
I have another serious gripe: It took hours for me to get the large tubing over the ends of the fittings, especially the end fitting at the end. Especially that one! I had to use all kinds of wrenches and clamps, practically destroying the tube in the process, and I drew blood from my hand when everything slipped and I got scraped.
I used vaseline. That only made everything slippery and harder to grip.
Again, something is very very wrong here. Although I have had two great seasons with growing plants in my two Earthboxes, this day in the hot sun trying to get the watering system to work or even to fit together destroyed all the goodwill I have for this company!
