Hey, THoc!
Man, sorry I missed your post.
The solution depletes at different rates, depending on what stage the plants are in, conditions, etc... Normally with the plants in full flower, it takes a day or two to deplete the charge.
When the solution depletes, there is a float on the valve that follows the level. When it reaches an empty situation, the float allows the valve to open up and allow in another charge.
If the valve were in a flat bottomed container, it would use up every bit of the solution before allow any more in, However, with the valve sitting in a rounded bottom tube, there is always about another 1/4"-3/8" of solution in the channel just below the valve, in the bottom of the pipe. It never gets completely dry, but close.
When the valve senses the solution is at an empty situation, it opens up and allows the next charge in. There is an additional float on the inside of the valve that flows up with the raising solution level. When the solution is 1" from the bottom of the valve, it stops the flow and waits until empty again.
