Sqydro,
the point of the float valve contraption being inside another container inside of the res is to control or restrict how fast the rez will top off from the main water supply
When the feed pump turns on, the water in your feed rez is delivered to each of the modules almost emptying your rez containing the nutrient, while waiting for the nutrient to drain from said modules and return to the rez back to it's beginning volume the float valve opens allowing water from you main water source to top off the rez.
If you remember the discussions of the "Air Gap", it is important to maintain that specified space between the surface of the water in the lower bucket and the bottom of the tub in each module. If the water from your main water source is allowed to top off the rez unrestricted, or too fast, then there will be too much water replacing that which is still draining from the modules on it's way back to the rez.
The end result is greater volume than desired in the rez, thus raising the water level and decreasing the "Air gap" that we are trying to maintain. So, the container inside the rez with the drilled holes and float valve is really just slowing the flow of water topping the rez during a feed because we cannot control the speed at which the water is flowing from the float valve itself.
hope this helps. I was in the same boat not so long ago, so many great people here willing to help.
