rodi automatic shut off

[pirate]

As I study the picture I had the previous one hooked up that way and no luck either, at least it looked that way without the pressure tank. |I had the most amount of luck when I had the shut off hooked up to the waste line,I had it pulsing but that was it. But if i don't have the water pressure to shutoff the solonide where can I buy just a plain shut off valve like the one pictured?

Well I've continued playing with it. And I hooked up the waste line to the float switch and it still will not shut off. And the pressure gauge reads 52-54 i don't have any leaks that I can find but I hear a sound like air/water rushing past something, and it's an internal type of noise so I think I might have an air issue. Any other things I should look at?
