Sprinkler systems are a helpful way to keep your yard green & healthy in O’Fallon, IL. It is important to know that sprinklers can run into problems. Knowing the signs of early issues can help prevent major issues with costly repairs. Whether you’re a homeowner or manage a commercial property, here are some of the most common issues you may encounter—and what you can do about them.
Clogged Sprinkler Heads
The head of the sprinkler can be clogged. Dirt, grass clippings, and other debris can block the nozzle, preventing water from spraying correctly or at all. You might see some dry patches which could indicate an uneven watering pattern. Cleaning the heads with a soft brush and rinsing them can usually fix this problem. In areas with hard water, mineral buildup can also be a culprit, and in those cases, soaking the head in vinegar may help.
Leaking Sprinkler Lines
Leaks in the sprinkler lines—either underground or near a sprinkler head—can waste significant amounts of water and cause soggy spots in your yard. These leaks are often caused by cracks in the pipe, worn-out seals, or shifting soil. Spotting them early is key. If your water bill suddenly spikes or you see unusually wet or muddy areas, it might be time to inspect the system or call in a professional.
Broken or Damaged Sprinkler Heads
Sprinkler heads can be easily damaged by anything from lawn mowers, pets, or anything else in your yard. A broken head might not pop up properly or could shoot water in the wrong direction. If you see water pooling or shooting up erratically, inspect the head and replace it if it’s cracked or severely worn.
Low Water Pressure
Sprinkler system efficiency can be hindered by low water pressure. This issue might stem from a partially closed valve, a leak in the line, or buildup in the pipes. It could also be related to municipal water supply issues. If all your heads are underperforming, it’s best to check the pressure regulator and consult a professional if the problem persists.
Zones Not Activating
Most sprinkler systems in O’Fallon, IL are divided into zones to cover different areas of the lawn. If one or more zones aren’t turning on, the issue could be electrical. Common culprits include faulty solenoids, broken wires, or a malfunctioning controller. Double-check the timer and controller settings first. If those look good, the issue might require a deeper electrical inspection.

Incorrect Sprinkler Head Placement
Improper spacing or placement of sprinkler heads can lead to uneven watering, with some areas receiving too much water while others remain dry. DIY installations are notorious for this issue. By repositioning and adjusting the spray patter, you can improve coverage and overall water efficiency.
