Most irrigation problems don’t announce themselves. A system doesn’t fail all at once — it degrades quietly, one head or one zone at a time, until the signs are obvious enough that the fix costs more than it would have a month earlier. Here’s what to actually watch for, and why Lafayette’s clay soil makes some of these signs show up later than you’d expect.
Uneven Coverage Is Usually the First Sign
If parts of the lawn are noticeably greener or browner than the rest in a consistent pattern, that’s not a watering problem you fix by running the system longer — it’s usually a clogged, broken, or misaligned head serving that specific area. Patchy coverage in the same spots every summer is a strong signal something in that zone needs a physical fix, not a scheduling change.
Standing Water or Runoff Onto Hardscape
Water pooling in a bed, or runoff reaching a driveway or walkway during a cycle, usually points to a broken head, a zone running longer than the soil can absorb, or pressure issues in that line. On Acadiana’s clay soil, this shows up faster than it would in sandier soil elsewhere — clay doesn’t absorb water quickly, so a minor overrun becomes visible runoff sooner.
A Water Bill That Doesn’t Match Your Usage
An unexplained jump in your water bill, with no corresponding change in weather or watering schedule, is one of the more reliable signs of an underground leak. That said, South Louisiana’s summer heat and drought stretches — typically July through September — naturally drive water bills up on their own, so a spike during those months isn’t necessarily a red flag. Outside of that window, though, a significant jump is usually worth having the system checked.
Mushy Spots That Never Fully Dry Out
An area that stays soft or spongy well after a watering cycle, even during a dry stretch, usually indicates a broken line or a valve that isn’t fully closing. This is different from a low spot that holds rainwater — it’s specifically an area that stays wet regardless of recent weather.
A Controller Nobody Has Touched Since Installation
If your irrigation controller is still running the schedule it had on day one, regardless of season, that’s worth a second look even if nothing looks obviously wrong yet. A schedule that made sense during installation often doesn’t match what the landscape needs even six months later, especially as plants mature and weather patterns change.
Plants or Turf Stressed Despite “Enough” Water
If certain areas look stressed even though the system is running on schedule, the problem often isn’t the amount of water — it’s whether that zone’s coverage actually matches what’s planted there. A zone designed for turf doesn’t necessarily deliver the right coverage pattern for a dense planting bed nearby, and stress in one area while the rest of the property looks fine is a sign of a design mismatch, not a watering failure.
Visible Equipment Issues
Heads that don’t pop up fully, visibly cracked components, or exposed pipe are the most obvious signs on this list — and also the easiest to ignore because they may not look urgent. A head that isn’t popping up fully is usually still running, just inefficiently, which means it’s using water without delivering the coverage it’s supposed to.
Why Catching This Early Matters More Here
A lot of the signs above show up later than when the actual damage started. By the time a leak surfaces or a dry patch becomes obvious, the inefficiency has usually been running for a while. A seasonal system check catches most of these before they show up as a symptom you can see from the driveway.
What a Seasonal Check Actually Catches
Most of the signs above have a common thread: by the time they’re visible, some amount of water, plant health, or turf quality has already been lost. A seasonal walk-through — checking each zone, watching heads cycle, and looking at pressure and coverage while the system is actually running — catches a misaligned head or a developing leak while it’s still a small, inexpensive fix. Waiting for a sign on this list to become obvious usually means waiting until the fix is bigger than it needed to be.
The One Thing Worth Doing Now
If it’s been a while since anyone looked at your system beyond the annual startup and shutdown, that’s usually reason enough to have someone check it out. Don’t hesitate to contact us if you’d like to schedule a technician to come take a look at your system.
