Filtering Roofwasher

The Filtering Roofwasher collects rain water from downspouts, then filters it before it enters the cistern. The first rain to fall on a roof washes off dirt and debris which has accumulated since the last rain. As this first and dirtiest water enters the roof-washer, the larger debris is removed by screens in the inchleaf-catcher inch compartments. This first water, which never enters the cistern, is collected and held in the bottom inchquiet chamber inch. Once the inchquiet chamber inch fills, additional incoming water begins passing through the filter element and into the cistern. A small inchweep hole inch in the overflow/clean-out pipe discards the dirty and allows the quiet chamber to drain between rains.
