Why does my grass die between two working sprinkler heads?
Short answer: Both sprinklers can operate normally while inadequate spacing leaves a coverage gap between them — each head waters its own area, but neither one reaches the strip in the middle.
Sprinklers are designed for head-to-head coverage: each head’s spray should reach the next head, so the areas overlap and the middle gets water from both sides. When heads are spaced too far apart — often after a layout change, a moved head, or a head that was never placed quite right — the middle strip gets little or no water, even though both heads look like they are working fine.
The dead strip between two healthy heads is the classic sign of a spacing problem. The fix is to move a head, add a head in the gap, or change nozzles so the spray reaches head-to-head again. Running the zone longer will not close the gap — it just over-waters the ground the heads already reach.
What we check in Humble
This is a common call in Humble, 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
Why does the gap show up in summer first?
In cooler months the lawn can get by on less water, so a small gap is easy to miss. In summer heat the gap dries out first and turns brown while the rest of the lawn holds up.
Is this the same as a clogged nozzle?
Not usually. A clogged nozzle changes one head’s pattern. A gap between two working heads, with both patterns looking normal, points to spacing.
