A well-functioning irrigation system is one of the most valuable assets a Johnson County homeowner can have. But like any mechanical system, sprinklers wear out, break down, and develop problems over time. Knowing the warning signs of a failing irrigation system can help you catch issues early — before a small repair turns into a costly replacement. Here are the top signs that your sprinkler system needs attention, from Hometown Lawn’s irrigation team in Olathe, KS.
1. Dry or Brown Patches Appearing in Your Lawn
If you’re noticing brown, dry patches in your lawn that don’t respond to rainfall, the most likely culprit is a failing sprinkler head or a zone that isn’t activating properly. A clogged nozzle, a head that’s tilted or sunken below grade, or a zone valve that’s stuck closed can all create dry spots that look like lawn disease but are actually irrigation coverage gaps.
2. Flooding or Standing Water Near Heads
On the opposite end, if you’re seeing soggy areas or standing water near sprinkler heads even when the system isn’t running, you likely have a head that isn’t sealing properly or an underground pipe with a leak. A leaking zone valve can also continuously weep water, creating consistently wet areas that damage turf and waste significant water over a season.
3. Low Water Pressure in a Zone
When you notice that a zone of your sprinkler system seems to be operating at lower pressure than it used to — with heads not popping up fully or rotors not rotating — it often indicates a broken head below the surface, a partially closed valve, or a break in the supply line for that zone. Low pressure dramatically reduces coverage efficiency and leaves parts of your lawn underwatered.
4. Sputtering, Misting, or Uneven Spray
Spray heads should produce a clean, consistent arc of water. If you’re seeing sputtering, misting, or an inconsistent pattern, the nozzle is likely clogged with mineral deposits or debris, or the head itself is damaged. Rotary heads that pause, skip, or rotate incompletely also need attention. These coverage issues waste water and leave portions of your lawn under- or over-irrigated.
5. Your Water Bill Is Unusually High
A sudden spike in your water bill during the growing season — without a change in your watering schedule — is a strong indicator of an irrigation leak. Underground pipe breaks, stuck-open valves, and broken heads can all cause your system to run water continuously or at much higher volumes than intended. Hometown Lawn can perform a full irrigation system audit to find and repair the source of the leak.
