5 Signs You Have a Hidden Irrigation Leak

June 02, 2025 Mike Johnson Troubleshooting

Irrigation leaks often go unnoticed until you get a massive water bill. Here are five signs to watch out for in your yard.

1. Unexplained Wet Spots

If you find muddy areas when the system hasn't run recently, you likely have a weeping valve or a broken pipe underground.

2. Low Water Pressure

If your sprinkler heads aren't popping up fully or are just misting, water is escaping somewhere else in the line.

3. Hissing Sounds

Walk near your valve box. A constant hissing sound when the system is off usually indicates a valve that isn't closing sealing properly.

4. Unusually Green Patches

One area of grass growing much faster and greener than the rest? It's getting extra water from a leak.

5. High Water Bill

The most obvious sign. Compare your usage to the same month last year. A sudden spike is a red flag.
