R/O unit auto shut off

[Madreefer]

With the Vertex the outfeed line goes in to this float valve. When the float valve raises it shuts off the water (filtered water and waste water). The unit than shuts down. It is a really simple system and requires no power. I did put another seperate line a few inches above this float valve in case of a failure but as I said this float valve has not let me down. The line to my resevoir is about 4ft from the unit. I hope I explained this good enough. I guess what i'm saying is the Vertex has a built in auto shut off should the outfeed of filtered water be blocked.
