      Roof Washers & Pre-Filters

      Rain Brothers' roof washers and pre-filters are the first line of defense in any rainwater harvesting system, intercepting debris, sediment, and first-flush contaminants before water ever reaches your tank or cistern.

      • First-Flush Diversion — Automatically diverts the dirtiest initial runoff away from your storage
      • Debris Interception — Screens out leaves, dirt, and particulates at the roofline
      • System Protection — Reduces wear on downstream filters, pumps, and UV systems
      • Potable & Non-Potable — Essential pre-filtration for both drinking water and irrigation systems

      Not sure which pre-filter is right for your roof area or flow rate? Contact us — we'll help you size it correctly.
