5 Signs Your Sprinkler System Needs Repair

A healthy irrigation system runs quietly in the background and keeps your lawn evenly green. When something goes wrong, the signs are usually there long before a zone stops working entirely. Catching them early keeps repairs small and your landscape healthy. Here are the five most common warning signs we see.

1. Dry or brown patches. If part of your lawn is struggling while the rest looks fine, a head is likely clogged, broken, or misaligned, or a zone isn't getting enough pressure. Uneven coverage is the number-one symptom of a system that needs attention.

2. A spike in your water bill. A sudden jump often means a hidden leak underground or a valve that isn't shutting off completely. Irrigation leaks can waste hundreds of gallons without ever showing at the surface.

3. Heads that mist instead of spray. A fine mist rather than clear droplets usually means the water pressure is too high, which wastes water to evaporation and drift. It's an easy fix that pays for itself.

4. Sputtering, uneven, or weak spray. Air in the lines, partially clogged nozzles, or failing valves all cause weak or inconsistent output. Left alone, these get worse and leave parts of your lawn thirsty.

5. Soggy spots or water pooling. Constant wet areas, especially near valve boxes, point to a leak or a stuck valve. Beyond wasting water, standing water invites disease and damages your turf.

If you've noticed any of these, don't wait for a zone to fail completely. Our repair and maintenance service pinpoints the real cause and gets every zone running efficiently again. Call us for a fast diagnosis and a free estimate.
