Filtering Roofwasher For Rain Water Cisterns

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 ''leaf-catcher'' compartments. This first water which never enters the cistern is collected and held in the bottom ''quiet chamber''. Once the ''quiet chamber'' fills additional incoming water begins passing through the filter element and into the cistern. A small ''weep hole'' in the overflow/clean-out pipe discards the dirty and allows the quiet chamber to drain between rains.
