What is sprinkler precipitation rate?
Short answer: Precipitation rate describes how quickly an irrigation system applies a depth of water to the landscape — usually measured in inches per hour — and it is what turns a runtime in minutes into an actual amount of water on the lawn.
A spray head might apply water at 1.5 inches per hour while a rotor applies it at 0.4 inches per hour. That means the spray zone reaches a target depth in a fraction of the time the rotor zone needs — and it is why sprays and rotors should not normally share a zone, and why a catch-can test (measuring how much water lands in cups across the zone) is the practical way to find your system’s real rate.
Knowing the precipitation rate is what makes runtimes make sense. If your zone applies half an inch per hour and the lawn needs an inch a week, that zone needs about two hours of total runtime a week, split across waterings — not a guessed number of minutes that may be far too much or far too little.
What we check in Fall Creek
This is a common call in Fall Creek, and it is the kind of problem we test in the yard instead of guessing at from the driveway. We run the system, watch how the water is actually moving, and check the parts that cause this — before anything gets replaced. That is the same approach in the full Sprinkler Installation service page.

Frequently asked questions
How do I measure my precipitation rate?
Set out straight-sided cans across the zone, run it for a set time, measure the depth in each can, and average them. That gives you inches per hour for that zone, in your yard, with your heads.
Why do spray heads and rotors have such different rates?
Sprays throw a fixed pattern quickly over a small area; rotors cover a larger area slowly. Same water, very different speed — which is why mixing them on one zone waters unevenly.
