Slow sand filter float valve flow control device in filter 3
The pvc pipe is 1/2 inch. There are .040 inch holes drilled on the bottom of the pipe to allow the water to disperse without disturbing the sand surface.
The float valve limits the volume of the flow of input water so it matches the volume of the flow of water through the filter. As the filter "ripens" its flow rate will slow down. The float valve will, by its nature of operation, slow the flow of water down equally.
