2. Select a '1' or '2' minute drain period.
Note: Where possible it is recommended to design based on a 1 minute drain period. Drain Period is however a convenience factor allowing a more compact (lower capacity interceptor to be used in the calculated application. The trade off is greater frequency of maintenance of that more compact solution.
Formula assumes a 1 minute drain period - For 2 minute enter '2'
