Spring startup is the most critical service for your irrigation system's longevity. Improper activation can cause thousands of dollars in damage, while a professional startup ensures your system operates flawlessly all season. Here's everything Long Island homeowners need to know about spring irrigation startup.
When to Schedule Spring Startup on Long Island
The optimal spring startup window for Nassau and Suffolk Counties is mid-April through early May. Here's why timing matters:
- Frost Risk: Ground temperatures must be consistently above 40°F to prevent freeze damage
- System Protection: Residual water from winterization needs to thaw completely
- Lawn Needs: Grass begins active growth and requires supplemental watering
- Service Availability: Schedule early for best appointment times
Warning Signs It's Too Early
- Nighttime temperatures still dropping below 32°F
- Frost on grass in the morning
- Ground feels frozen or extremely hard
- Ice still visible around backflow preventer
The Professional Spring Startup Process
Here's our proven 10-step process developed over 28 years of Long Island irrigation service:
Step 1: Visual System Inspection
Before touching any water valves, we thoroughly inspect the entire system for winter damage:
- Check all visible pipes for cracks or breaks
- Inspect backflow preventer for freeze damage
- Examine valve boxes for water accumulation
- Look for signs of rodent or insect damage
- Check controller battery and programming
Step 2: Backflow Preventer Inspection
The backflow preventer is most vulnerable to freeze damage. We carefully:
- Remove any protective covering or insulation
- Inspect all test cocks and ball valves
- Check for cracks in the brass or plastic housing
- Verify check valves move freely
- Test relief valve functionality
Critical Note: A cracked backflow preventer must be replaced before system activation. Operating with a damaged backflow is illegal and poses health risks to your water supply.
Step 3: Gradual Water Introduction
This is the most critical step. We slowly open the main water valve:
- Open valve 1/4 turn and wait 30 seconds
- Listen for unusual sounds (rushing water, hissing)
- Check for visible leaks around connections
- Gradually open to 1/2, then 3/4, then fully open
- Total process takes 3-5 minutes, never rushed
Why Go Slow? Rapid water introduction creates pressure surges that can rupture weakened pipes, blow apart compression fittings, and damage valve diaphragms. The gradual approach identifies problems before they become catastrophic.
Step 4: Zone-by-Zone Activation
We activate each zone individually, never running multiple zones simultaneously during startup:
- Run each zone for 2-3 minutes
- Watch for geysers indicating pipe breaks
- Look for dry spots indicating clogged heads
- Check for misting indicating damaged nozzles
- Verify proper pop-up and retraction of heads
Step 5: Sprinkler Head Inspection
While each zone runs, we inspect every sprinkler head:
- Clean filters and nozzles of debris
- Adjust spray patterns for proper coverage
- Level heads that settled over winter
- Replace cracked or broken heads
- Ensure proper arc and distance settings
Step 6: Backflow Testing
Suffolk County requires annual backflow testing. We:
- Perform complete backflow preventer test
- Document all pressure readings
- File required county paperwork
- Provide you with compliance documentation
- Make any necessary repairs or adjustments
Step 7: Controller Programming
We program your controller for early-season needs:
- Set appropriate run times for spring weather
- Program for early morning operation (4-8 AM)
- Enable rain sensor functionality
- Set appropriate days per week (typically 2x)
- Verify battery backup functionality
Step 8: System Pressure Check
Proper pressure is critical for system longevity:
- Measure static water pressure
- Check dynamic pressure with zones running
- Verify pressure is 40-65 PSI (optimal range)
- Install pressure regulator if needed
- Adjust pressure reducer on backflow if present
Step 9: Rain Sensor Verification
An essential but often overlooked component:
- Test sensor functionality with water spray
- Verify it halts system operation when wet
- Adjust sensitivity for Long Island rainfall
- Clean sensor contacts of corrosion
- Replace battery if sensor is wireless
Step 10: Complete System Test
Final verification of complete system operation:
- Run complete automatic cycle
- Verify all zones activate in sequence
- Confirm proper zone shut-off
- Check for any leaks under pressure
- Walk entire property for final inspection

DIY vs. Professional Spring Startup
Can You DIY?
Technically yes, if you're comfortable with the process and have time to thoroughly inspect the system. However, consider:
- Knowledge: Do you know what a healthy valve sounds like?
- Experience: Can you spot a failing diaphragm before it fails completely?
- Tools: Do you have a backflow testing kit and proper gauges?
- Liability: Are you prepared to fix problems you might create?
- Time: Proper startup takes 60-90 minutes minimum
Why Choose Professional Service
- Experience: We've started thousands of systems and know every potential issue
- Efficiency: What takes homeowners 3+ hours, we complete in 60-90 minutes
- Equipment: Professional-grade tools and testing equipment
- Certification: Licensed for required backflow testing
- Warranty: Our work is guaranteed; DIY mistakes aren't
- Peace of Mind: Sleep well knowing it's done right
