Flow Rate for the FloPlast Hoppers?

What is the Flow Rate for the FloPlast Hoppers?
The flow rate of FloPlast hoppers varies depending on the model. Below are the flow rates for different hopper sizes, along with the recommended roof area coverage: 
  • RH1 / RHS1: Flow rate of 1.14 lts/sec, suitable for 54.5 sq/m of roof area
  • RH4: Flow rate of 2.18 lts/sec, suitable for 104.5 sq/m of roof area
  • RH5: Flow rate of 2.18 lts/sec, suitable for 104.5 sq/m of roof area
  • RHH1: Flow rate of 1.66 lts/sec, suitable for 79.5 sq/m of roof area
These flow rates are designed to ensure that each hopper can effectively manage the water runoff from the corresponding roof area, providing optimal performance and preventing overflow during heavy rainfall.
