Stop chasing brown spots and mystery puddles
What “sprinkler repair” usually means (and why it matters)
The big clue: is it one head, one zone, or the whole system?
Did you know? Quick sprinkler facts that save lawns
- A clogged nozzle or filter screen is one of the most common reasons for weak or uneven spray patterns.
- If several heads in the same zone won’t pop up, the issue is often pressure loss (leak, partially closed valve, or flow demand too high)—not “bad heads.”
- A “geyser” or constant bubbling around a head usually means a broken head or cracked fitting/pipe—and it can drop pressure enough to ruin coverage nearby.
- In the Treasure Valley, sprinkler systems should be winterized (blown out) before the first hard freeze to reduce freeze-related damage to exposed irrigation components.
Common sprinkler problems in Caldwell (and what to check first)
1) Dry spots or “striping” in the lawn
Fast check: run the zone and watch each head. Look for a head spraying pavement, hitting a fence, or creating a “donut” pattern close to the head. If the spray is uneven, remove and rinse the nozzle and any filter screen (if your model uses one).
2) Heads not popping up (or only halfway)
Fast check: if it’s just one head, clean/replace it. If it’s multiple heads in the same zone, stop replacing parts and look for pressure loss—soft, soggy areas or an unusually green patch can indicate a buried leak.
3) One zone won’t turn on
Fast check: try running the zone manually from the controller first (to isolate schedule problems). If the zone is still dead, it’s time for valve/solenoid diagnostics—especially if other zones work normally.
4) A zone won’t shut off
Fast check: shut off irrigation at the main if needed to prevent flooding, then plan for a valve inspection. This is one of those issues where a quick professional fix can prevent serious water waste and landscape damage.
5) Random wet spots, sinking soil, or unusually fast water bills
Fast check: run zones one at a time and watch for pooling or bubbling. Leaks that bleed pressure can also create dry spots at the far end of the same zone—so you may see both “too wet” and “too dry” symptoms at once.
