Rainwater catchment systems conference in KMC

[Scott_S]

Some time ago on the web I seen this device for sale, it include a floating ball and a valve. You tee off between the tank and the gutter install this and a drop leg as long as you want. The drop leg has a hole in it to let it drain slowly. The idea was to catch the first run off, the ball floats up to seal the drop leg, and later the drop leg drains off. I will search the web again to see if I can find it.

first flush system-duh:
