How many zones does this yard need? Start with total flow, not a guess.
Once the heads are placed, add up what they ask for. In Pro Contractor Studio, Irrigation > Total Flow totals every sprinkler on the plan by category. With a water source on the plan, it also suggests a number of zones and a recommended flow per zone.
That number is a starting point. Before you lock in zones, check:
1. Turf and shrub heads are not sharing a zone.
2. Sun and shade areas are split.
3. Slopes are grouped by position, top separate from bottom.
The screenshot shows the Total Flow result for our sample yard next to the zones we actually drew.
Save this for your next layout.
