5 Signs Your Sprinkler System Needs Repair

Most sprinkler system problems do not appear overnight. They develop gradually and often go unnoticed until the lawn starts showing visible damage or the water bill jumps unexpectedly. In Wylie, TX and across the area, the combination of extreme heat, clay soil, and winter freezes means irrigation systems take on a lot of stress over time.

Knowing the early warning signs can help you catch a problem before it becomes an expensive repair or leaves your lawn without water during the hottest months of the year. Here are the five most common signs that your sprinkler system needs professional attention.

1. Dry patches or dead spots in your lawn

If you have areas of your lawn that stay brown or dry even when the rest of the yard looks healthy, the sprinkler system is not covering those spots properly. This is one of the most common signs of a sprinkler problem and one of the easiest to miss because it develops over weeks rather than overnight.

Dry patches can be caused by broken or clogged sprinkler heads, heads that have settled or tilted out of alignment, zones with low water pressure, a valve that is not opening fully, or simply gaps in coverage from a system that needs adjustment. In many cases, the fix is straightforward once the cause is identified.

2. Soggy or waterlogged areas that stay wet

The opposite problem is equally telling. If you have areas in your yard that are always wet, stay soft underfoot, or develop puddles long after the sprinklers have run, you likely have a leak. Common culprits include a sprinkler head that is stuck in the open position, a valve that is not closing completely, a cracked underground pipe, or low-head drainage pulling water downhill to the lowest sprinkler in a zone.

Persistent wet areas near fences, foundations, or sidewalks deserve prompt attention. Extended moisture near your home’s foundation can create bigger problems over time, particularly in the area where foundation movement is already a concern on clay soils.

3. Zones that won’t turn on, or won’t turn off

A zone that refuses to turn on is usually caused by a bad solenoid, a broken wire, a failed valve, a tripped fuse in the controller, or water in the valve box. A zone that won’t turn off is most often a stuck or damaged valve, debris caught in the valve diaphragm, or a solenoid that is holding the valve open electrically.

Both issues should be addressed promptly. A zone that won’t water means part of your lawn is going without irrigation. A zone that won’t stop can waste hundreds of gallons before anyone notices, particularly if it happens overnight.

4. Low water pressure or weak sprinkler coverage

If your sprinklers are barely reaching their normal spray distance, or rotors are moving slowly and not covering the full arc, you have a pressure problem. Low pressure in a single zone usually points to a leak, a partially closed valve, or too many heads on that zone. Low pressure across all zones may indicate a pressure regulator issue, a problem with the backflow device, or a supply line concern.

Weak coverage means parts of your lawn are being underwatered even when the system appears to be running normally. Over the course of a hot Texas summer, that can add up to significant lawn damage.

5. Your water bill has increased unexpectedly

A sudden increase in your water bill without a change in your watering schedule is one of the clearest signs of an underground leak or a zone running longer than it should. Underground leaks in irrigation systems can go undetected for weeks if the leak is slow and the water drains away from the surface.

If you suspect your irrigation system is using more water than it should, a professional system check can identify leaks, misfiring zones, incorrect run times, or programming errors that are driving up consumption. In Wylie and across the area, water rates make undetected leaks genuinely costly over the course of a summer.

What to do if you notice these signs

Most of these problems are repairable, often in a single visit. The key is not to wait. A small leak becomes a bigger one. A dry patch becomes dead turf. A zone that barely reaches its target wastes water while still underperforming.
