As the summer heat approaches, ensuring your lawn and landscape stay healthy becomes a top priority. An efficient irrigation system is the backbone of maintaining lush grass, vibrant flower beds, and productive gardens. However, before the hottest months set in, your system needs a thorough check and fine-tuning to avoid water waste, uneven coverage, and unexpected breakdowns.
Here’s a step-by-step guide on how to prepare your irrigation system for peak summer performance.
1. Inspect the Entire System
Start with a full inspection of your irrigation system. Look for:
-
Broken or cracked sprinkler heads
-
Leaky valves or pipes
-
Clogged nozzles or emitters
-
Dry spots in your lawn or garden
Even small leaks can result in hundreds of gallons of wasted water over the summer, not to mention higher utility bills.
2. Test Water Pressure
Excessively high or low water pressure can reduce system efficiency. High pressure can damage sprinkler heads, while low pressure may lead to insufficient watering. Use a pressure gauge at the system’s spigot or backflow preventer. Ideal residential irrigation systems typically operate between 30–50 PSI.
If pressure is off, you may need to adjust the pressure regulator or consult a professional for further diagnosis.
3. Clean and Adjust Sprinkler Heads
Sprinkler heads often accumulate dirt, lawn clippings, or mineral deposits. Clean them with a soft brush and water. After cleaning, adjust the direction and arc of the spray to ensure it’s targeting the right areas—grass and plants only, not sidewalks or driveways.
This step maximizes watering efficiency and reduces waste.
4. Check the Timer and Programming
Review the irrigation controller to ensure it’s properly programmed for summer watering needs. Consider:
-
Watering early in the morning or late evening to minimize evaporation
-
Short, multiple cycles to allow better soil absorption
-
Adjusting frequency based on plant types (e.g., lawns need more water than drought-tolerant shrubs)
Smart controllers that adapt based on weather forecasts and soil moisture levels can further optimize water usage.
5. Replace Worn or Inefficient Components
If your system includes older spray heads, consider upgrading to more efficient options like rotary nozzles or drip irrigation. These technologies provide more uniform coverage and reduce runoff.
Modern systems can also be enhanced with soil moisture sensors, rain shut-off devices, and Wi-Fi controllers for even greater efficiency.
6. Perform a Test Run
Once you’ve made all repairs and adjustments, run the system zone by zone. Look for:
-
Consistent water coverage
-
Sprinklers turning on and off correctly
-
Any pooling or overspray
-
Audible signs of pressure issues or air in the lines
This dry run helps you spot lingering problems before your landscape depends on the system during peak summer heat.
7. Schedule Regular Maintenance
A one-time summer prep isn’t enough. Build a seasonal maintenance plan that includes:
-
Monthly sprinkler head inspections
-
Mid-season system tune-ups
-
Adjustments after heavy rain or drought periods
These proactive steps will extend the life of your irrigation system and keep your landscape in peak condition.
8. Consider Professional Help
If you’re unsure about handling these tasks or want to ensure everything is calibrated correctly, hiring professional irrigation system services can save time and prevent costly errors. Experts can perform detailed diagnostics, make complex repairs, and suggest upgrades that suit your landscape’s unique needs.
Preparing your irrigation system for summer is a smart move for both your landscape and your wallet. A well-maintained system uses water efficiently, supports healthy plant growth, and minimizes the risk of mid-season breakdowns. Whether you’re doing it yourself or calling in the pros, early preparation pays off when the temperature starts to climb.
Keep your system running at its best—because a green, thriving yard is one of summer’s greatest rewards.
