Hello,

Forgive me if this has been answered. I’ve been digging through the support community info for a couple of hours and have just become more confused on this as I go.

I have all fixed-spray head nozzles in my yard.

My question is, when I configure a zone and I choose a ‘Fixed Spray Head’ (1.5 in/hr) as the primary nozzle type for a zone, do the watering calculations assume there is ‘1’ spray head in the zone?

If I understand correctly, if I have a zone with 6 spray-heads, this would deliver 9 in/hr (1.5in/hr x 6 spray heads) and would lead to a smaller watering time.

Should I create a custom nozzle with 9 in/hr to account for multiple spray heads in a zone?

I understand the Precip rate formula PR = (96.25 x GPM)/ square feet

I understand that the GPM calculation here includes the GPM of all heads in the zone (so, for example, 1 GPM per head x 6 heads would be 6 GPM in the PR formula).

But I don’t understand if the Iro is assuming one head or some default number of heads or what in each zone (or do the number of heads somehow not matter in the calculation)?

Thanks,
