Calculate your quantity
Sketch positions only. A complete system needs a pressure and flow check.
How this estimate works
A rectangular sketch uses one position at each end and divides the spans by the entered maximum spacing.
The arithmetic describes a planning volume or sketch. Local climate, plant needs, pressure, flow, rainfall, and equipment ratings determine actual irrigation design.
Before you order
- Check local weather and plant water needs.
- Confirm equipment pressure, flow, and manufacturer coverage.
- Check local water rules and the site drainage path.
Planning estimates can differ from delivered or installed quantities.
