Quick Answer
A First Flush Diverter can be adapted for larger roof areas by using larger or multiple diverters, and considering factors like roof slope, gutters, and water volume.
Choosing the Right Diverter Size
When selecting a First Flush Diverter for a larger roof area, it’s essential to consider the flow rate of the diverter. A standard 1-inch diverter can handle roof areas up to 1,000 square feet, with a flow rate of around 2-3 gallons per minute (GPM). For larger areas, a 1.5-inch or 2-inch diverter may be necessary, with flow rates of 3-5 GPM and 5-7 GPM, respectively.
Installing Multiple Diverters
If a single diverter is not sufficient for the larger roof area, multiple diverters can be installed to handle the increased water volume. This can be done by installing multiple diverters in series or in parallel, depending on the roof layout and water flow requirements. For example, two 1-inch diverters can be installed in series to handle a roof area of 2,000 square feet, with a total flow rate of 4-6 GPM.
Considerations for Large Roof Areas
When installing a First Flush Diverter on a large roof area, it’s crucial to consider the roof slope, gutter size, and water volume. A steeper roof slope may require a larger diverter to handle the increased water flow, while a smaller gutter size may require a more frequent cleaning schedule to prevent debris buildup. Additionally, the water volume from a large roof area may require a larger storage tank to accommodate the increased water supply.
