Spring Start-Up Guide for Your Lawn Irrigation System


Winter has a way of making everybody sort of sluggish. 

Bears hibernate. Your couch is extra popular. Even your sprinkler system is out there lazing around, asleep under its blanket of snow. 

But spring is like a jangling alarm clock. Time to kick things into gear — including irrigation system spring startup.

It’s not exactly raring to go. Remember last fall, when you shut your system down for the winter, blowing out the pipes and turning off the water to protect it from winter damage? It’s been asleep for a few months. The water is off. Heads are probably clogged with debris. Maybe they got bumped by snow plows so they’re pointing the wrong way, or broken. 

Spring sprinkler system startup makes sure everything is working properly and your sleepy sprinkler system is ready to wake up and get started on a new season of efficient watering. It’s a key part of irrigation services in Idaho. 

How to start up an irrigation system in spring?

Let’s take a look.

How to Turn on Your Sprinkler System After Winter

Spring sprinkler system startup is a process, with a few key steps involved:

1. Head to the Main Valve

It’s likely in your basement or crawl space. Make sure it’s in the off position. The handle should be 90 degrees to the pipe.

2. Set the System to Manual

You’ll be testing each zone to make sure it’s working properly, so you need it set to manual, not automatic. 

3. Close the Screws on the Vacuum Breaker

Find your vacuum breaker, outside near your sprinkler control valve. It should have two large valves with rubber handles and two smaller bleeder valves with screw-type shutoffs.

Use a screwdriver to twist the screws until they’re perpendicular to the valve.

4. Open the Large Valves on the Vacuum Breaker

Now open the large valves on the vacuum breaker, turning the handles a quarter turn until they’re parallel to the pipes.

5. Replace the Bleeder Valve Caps

Your vacuum breaker bleeder valves typically have caps over their threads to protect them that are removed over the winter to prevent them from freezing. Now that it’s time for irrigation system spring startup, twist them back down with a pair of pliers.

6. Slowly Open the Main Valve

Head back to the main sprinkler control valve and slowly open it. The key word here is slowly. You want to allow the pipes to fill with water gradually. Water suddenly rushing through your irrigation system can cause damage, breaking fittings, valves, and sprinkler heads. Easy does it.

7. Test Each Zone

Manually activate each irrigation zone from the controller.

Is each head rotating properly? Spraying where it should? Do you see any leaks? 
As you inspect each zone, adjust heads as needed and remove any debris that might be clogging them. 

Does the pressure seem low in any of the heads?  Low pressure can indicate problems, like a leak in your line.

8. Reprogram Your Controller

Remember, you can’t just set your controller and forget it. Watering needs change throughout the seasons, so adjust accordingly.

Better Yet, Leave it to the Pros

Does all this sound like a foreign language? Are you suddenly panicked about water surging through your sprinkler system? Do you have way better things to do with your time, now that spring is finally here? 

You can actually damage your sprinkler system with irrigation system spring start up tasks if you’re not sure what you’re doing out there.

Why not leave it to the pros?
