How to Start Irrigation System in Spring: Big Tips for Success
As winter fades away and warmer days arrive, it’s time to bring your landscape back to life. One of the most important tasks for a healthy lawn and garden is starting your irrigation system in spring. A properly functioning irrigation system ensures that your plants get the right amount of water while preventing waste.
If you’re unsure about the correct process, this guide will walk you through step-by-step instructions on how to start an irrigation system in spring. By following these steps, you can prevent costly repairs and ensure efficient watering for your lawn and garden.

Why Spring is the Best Time to Start Your Irrigation System
Spring is the ideal time to restart your sprinkler system because:
- The ground has thawed, preventing water lines from freezing.
- Plants and grass need consistent watering to recover from winter.
- Detecting damage early can save costly repairs later.
Step-by-Step Guide on How to Start Irrigation System in Spring
1. Inspect the System for Damage
Before turning on your sprinkler system, inspect it carefully. During winter, pipes may freeze, crack, or develop leaks. Walk around your yard and look for:
- Broken or misaligned sprinkler heads.
- Visible cracks in pipes and connections.
- Water pooling, which may indicate an underground leak.
2. Check for Leaks in Pipes
Leaks in your irrigation system can cause water waste and increase your water bill. If you notice any leaks, make sure to seal them immediately. Learn how to fix common leaks with this guide: Fix Small PVC Pipe Leak.
3. Slowly Turn on the Water Supply
It’s crucial to turn the water back on slowly. If you rush this step, the sudden surge of water pressure can cause burst pipes and damage to the system.
Follow these steps:
- Locate the main water supply valve.
- Turn the valve slowly to allow water to flow gradually.
- Listen for unusual noises that may indicate leaks or air pockets.
4. Adjust and Clean Sprinkler Heads
Over time, dirt and debris can clog your sprinkler heads. Cleaning them ensures proper water distribution.
Steps to clean sprinkler heads:
- Remove each sprinkler head carefully.
- Use a soft brush and water to remove dirt and residue.
- Reattach and align them to spray in the right direction.
5. Test Each Zone
Most irrigation systems have multiple zones, each covering different areas of your lawn. Run a test cycle for each zone and observe:
- Are all sprinklers working correctly?
- Is water reaching the intended areas?
- Are there any unusual puddles that may indicate leaks?
6. Program the Sprinkler Timer
A well-programmed timer ensures water efficiency and prevents overwatering. In spring, you may need to adjust settings according to weather conditions.
Generally, watering your lawn in the early morning is best to prevent evaporation and fungal diseases.
7. Monitor Water Usage
Keeping an eye on water consumption helps in conservation efforts and reduces costs. Find out how much water irrigation systems use in this guide: Water Usage Guide.

Common Problems When Starting an Irrigation System in Spring
Pressure Issues
If some sprinklers have weak water flow while others are overly strong, you may have a pressure imbalance. Check for partially closed valves or blockages.
Leaking Pipes
Leaks can cause serious water waste. If you need help fixing a pipeline leak, read this guide: Fix Pipe Leaks.
Clogged Nozzles
Clogged nozzles prevent sprinklers from spraying evenly. Cleaning them regularly prevents performance issues.
Conclusion
Taking the time to carefully restart your irrigation system in spring ensures a healthy, green lawn and efficient water use. Regular maintenance will prevent costly issues and water wastage in the long run.
