A Complete Seasonal Check
What Is Included in a Spring Sprinkler Startup?
A professional sprinkler startup should do more than simply turn the water supply back on. During your spring activation, Outdoor Legacy can:
Inspect the Backflow / Vacuum Breaker Assembly
We inspect exposed irrigation backflow components for visible leaks, damage, and operating problems that may have developed through the winter.
Test the System Zone by Zone
Each irrigation zone is operated so we can see how the system is functioning rather than assuming everything survived winter correctly.
Check Sprinkler Heads & Water Flow
We look for broken or damaged sprinkler heads, poor spray patterns, low pressure, leaks, or other obvious performance issues.
Check Valves
Sprinkler valves are checked to make sure zones are opening and closing as expected.
Check the Controller
The irrigation controller is turned back on, checked for proper operation, and programmed for the beginning of the watering season as appropriate.
Identify Needed Repairs
If we find cracked lines, damaged heads, malfunctioning valves, controller issues, wiring problems, or winter-related damage, we’ll explain what we found and what repair is recommended.
Find Problems Before Regular Watering
Why Have Your Sprinkler System Professionally Activated?
Your irrigation system has been sitting unused through months of freezing temperatures, snow, soil movement, and changing weather conditions.
Even when a sprinkler system was properly winterized, spring is a good time to confirm that everything is still operating correctly.
Finding problems during startup is much better than discovering them after your lawn begins drying out—or after a leak has been running unnoticed.
- Cracked or damaged sprinkler lines
- Broken sprinkler heads
- Leaking valves
- Backflow-related problems
- Controller issues
- Zones that won’t turn on
- Zones that won’t shut off
- Low water pressure
- Uneven sprinkler coverage
- Winter-related damage
- Heads that shifted or became misaligned
Colorado Spring Timing
When Should You Turn Your Sprinklers On in Colorado?
Colorado spring weather can be unpredictable.
Outdoor Legacy generally recommends waiting until overnight temperatures are consistently above freezing before activating your irrigation system.
Late April into May is often the typical window.
For the Centennial and South Denver area, timing depends on the year’s weather. Turning the system on too early can expose irrigation components to additional freeze risk if temperatures drop again.
You can schedule ahead of time even if the weather isn’t quite ready yet. Spring appointments can fill quickly once temperatures begin warming consistently.
Startup and Repair Are Separate
What If You Find a Sprinkler Problem During Startup?
Spring startup is often when irrigation problems that developed during winter first become visible.
The spring activation and sprinkler repair are separate services. If a repair is needed, we’ll identify the problem and explain the recommended repair rather than simply adding unexpected work to the seasonal service.
Many common repairs can be addressed during the same visit when time, parts, and scope allow. Larger line repairs, electrical issues, or backflow work may require a separate repair scope or appropriately qualified service.
- Cracked irrigation lines
- Broken sprinkler heads
- Damaged nozzles
- Failed sprinkler valves
- Controller problems
- Wiring issues
- Backflow-related damage
- Poor coverage
- Low pressure

Spring Startup + Fall Winterization
Colorado sprinkler systems need attention at both ends of the watering season.
Spring Startup
Carefully bring the irrigation system back online, test operation, identify problems, and prepare for watering season.
Fall Blowout
Remove water from the irrigation system before freezing temperatures can damage pipes and components.
Careful Seasonal Service
More Than Just Turning the Water On
With 35+ years of irrigation and landscaping experience, Outdoor Legacy approaches spring startup as an opportunity to make sure your system is actually ready for the season.
We’re not interested in simply turning on the water, seeing sprinklers come up, and moving to the next property.
The system should be checked so potential problems can be identified before they turn into wasted water, damaged landscaping, or larger repair issues.
Careful seasonal maintenance now can prevent surprises later in the watering season.What to Expect

Helpful Answers
Spring Sprinkler Startup FAQs
When should I turn my sprinklers on in Colorado?
Wait until overnight temperatures are reliably above freezing. In Centennial and the South Denver metro, that is commonly late April into May, although weather varies from year to year.
What is included in a sprinkler startup?
Outdoor Legacy activates the water supply, checks the irrigation system, operates the zones, inspects sprinkler components, checks controls, and identifies problems that may require repair.
Do you test every sprinkler zone?
Yes. Each irrigation zone should be operated during startup so problems can be identified before the system begins regular seasonal watering.
Can I turn my sprinkler system on myself?
Homeowners can activate many systems themselves. However, a professional startup also provides an opportunity to inspect the system for leaks, damaged components, valve problems, coverage issues, and other conditions that may not be obvious simply from turning the controller on.
What if you find a leak?
If a leak or other sprinkler problem is discovered during activation, we’ll identify the issue and explain what repair is recommended. Repair charges are separate from the startup service.
Can sprinkler repairs be completed during the same visit?
Many common sprinkler-head, nozzle, valve, and adjustment repairs can often be completed after the issue is identified when time, parts, and scope allow. Larger pipe, wiring, or backflow-related repairs may require additional work or a separate scope.
What happens if it freezes after my sprinkler system has been activated?
Colorado weather can change quickly. If freezing temperatures are forecast after activation, follow appropriate freeze-protection steps for your irrigation system and exposed components.
Do you service different sprinkler brands?
Yes. Outdoor Legacy services all major irrigation brands.
How much does spring sprinkler startup cost?
Outdoor Legacy’s spring sprinkler startup and activation service is $95 for up to 8 zones, plus $5 per additional zone. Repairs discovered during the startup are separate.
Do you also winterize sprinkler systems?
Yes. Outdoor Legacy provides fall sprinkler blowout and winterization services to help protect irrigation systems before freezing weather arrives.
