Why does my sprinkler head spray farther than it should?
Short answer: Usually because the pressure at the head is too high, or the nozzle throws farther than the area needs. The nozzle and operating pressure affect how far a sprinkler throws water.
A nozzle is rated to throw a certain distance at a certain pressure — for spray nozzles, usually around 30 PSI. When the pressure at the head is well above that, the spray throws farther than designed and starts to break into mist. The extra distance is not useful coverage; it is water landing where it was never meant to go, often on a driveway, sidewalk, or the neighbor’s yard.
The other common cause is simply the wrong nozzle for the space: a 15-foot nozzle on a 10-foot strip of grass will overshoot no matter what the pressure is. That happens when a head is replaced with whatever nozzle was on hand instead of the one the layout calls for.
We check the pressure at the head and the nozzle that is installed. If pressure is the problem, a pressure-regulated head that holds the nozzle at 30 PSI fixes the throw and stops the misting. If the nozzle is wrong for the space, we swap it for the right radius.
What we check in Humble
We measure the pressure at the head and read the nozzle that is installed. If the pressure is running high, we check whether pressure-regulated heads are the right fix for the zone. If the nozzle radius is too long for the area, we replace it with one that matches the space.

Frequently asked questions
Does higher pressure mean better coverage?
No. Above the nozzle’s design pressure the spray throws farther but breaks into mist, so more water is lost to wind and evaporation and the pattern gets uneven. The right pressure beats more pressure.
How far should a spray head throw?
As far as the area it serves — the nozzle radius should match the distance to the next head or the edge of the lawn, not overshoot it onto concrete.
