What type of spray head or nozzle do I have?

The type of spray head, or nozzle, used in a particular zone has one of the biggest impacts on initial watering time. The precipitation rate is the amount of water applied in a given amount of time over a given area (square footage) and is commonly expressed in inches per hour.

How do I edit the precipitation rate?

There are various ways to determine the actual nozzle precipitation rate, but one of the more accurate ways is to use a catch cup test. After determining the actual precipitation rate (inches per hour), you can customize the precipitation rate within the advanced settings of your zones.
