As Seattle’s winter rains give way to spring showers, homeowners across the Puget Sound region are preparing their irrigation systems for the growing season. While our area’s unique climate presents specific challenges, a proper spring startup ensures your sprinkler system operates efficiently throughout the warmer months ahead.
From Bellevue’s rolling hills to Redmond’s tech corridors, Advanced Irrigation has helped Puget Sound homeowners protect their sprinkler systems for over 30 years.
Why Timing Matters in the Pacific Northwest
Unlike other regions, Seattle’s spring brings a distinctive pattern of alternating rain and dry spells. The key is timing your system startup when:
- Nighttime temperatures consistently stay above freezing
- The soil has thawed completely
- Spring rain patterns begin to become less frequent
- Early spring plants show signs of active growth
Typically, mid-March to early April provides the ideal window for most Puget Sound neighborhoods, though proper winterization from the previous season gives you more flexibility with timing.
Seattle’s unique spring weather patterns require more than just turning on your water. Proper system startup prevents costly repairs and ensures efficient watering all season long.
Essential Spring Startup Steps
1. Initial System Inspection
Before introducing water to your system, conduct a thorough visual inspection:
- Check for obvious damage to exposed pipes
- Look for shifted or damaged sprinkler heads
- Inspect valve boxes for standing water or debris
- Verify controller functionality
2. Gradual System Pressurization
This critical step prevents damage to your irrigation components:
- Locate your main water valve
- Turn the water on slowly (1/4 turn at a time)
- Allow several minutes between turns
- Listen for unusual sounds that might indicate leaks
Pro Tip: If you hear water hammering or notice any leaks, our guide to detecting irrigation leaks can help you identify and address issues quickly.
3. Zone-by-Zone Evaluation
Test each zone individually:
- Check for proper head rotation
- Verify spray patterns and coverage
- Look for clogged nozzles
- Ensure heads pop up and retract properly
- Adjust spray patterns to avoid hardscapes
4. Smart Controller Programming
Seattle’s spring weather requires strategic programming:
- Start with shorter, less frequent watering cycles
- Gradually increase duration as temperatures rise
- Program different schedules for sunny and shaded zones
- Enable rain sensor functionality (if equipped)
- Consider upgrading to a smart controller for optimal efficiency
Special Considerations for Puget Sound Properties
Backflow Prevention Testing
Spring startup is the perfect time for annual backflow testing. Washington State regulations require annual testing of all backflow prevention devices. Learn more about backflow testing requirements and schedule your inspection early to ensure compliance.
Moss and Growth Issues
Seattle’s damp climate creates unique challenges:
- Check for moss growth around sprinkler heads
- Clear organic debris from spray patterns
- Adjust heads to prevent overwatering mossy areas
- Consider installing pressure-regulated heads in problem areas
Soil Conditions
Our region’s soil characteristics require special attention:
- Test soil moisture levels before programming
- Account for clay content in watering duration
- Adjust spray patterns for sloped areas
- Consider cycle- and soak-programming for better absorption
Professional vs. DIY Considerations
While some homeowners can handle basic startup procedures, choosing a professional irrigation team to set up your system offers several advantages:
- Complete system inspection and diagnostics
- Professional backflow testing and certification
- Updated programming based on current weather patterns
- Early detection of potential issues
- Compliance with local water regulations

Maintenance Tips for the Season Ahead
Monthly Checks
Establish a routine maintenance schedule:
- Monitor head performance and spacing
- Check for leaks or unusual wet spots
- Adjust programming based on weather changes
- Clear debris from heads and nozzles
Water Conservation Strategies
Implement these water-saving techniques:
- Water during early morning hours
- Adjust run times based on precipitation
- Install moisture sensors if needed
- Consider drip irrigation for beds and gardens
Getting Help When Needed
Remember, while this guide covers the basics, every irrigation system is unique. If you encounter any issues during startup or need professional assistance, it’s best to contact certified irrigation specialists who understand Seattle’s specific challenges.
Preparing for Success
A properly executed spring startup sets the foundation for efficient irrigation throughout the growing season. By following these guidelines and staying attentive to your system’s performance, you’ll ensure healthy landscape growth while conserving water and maintaining compliance with local regulations.
Remember to schedule your backflow testing early, as appointments fill quickly during peak spring startup season.
