When to Open Your Sprinklers and How to Prep for Spring in Denver

As the cold weather fades and spring begins to bloom in Denver, homeowners start thinking about yard maintenance, including when to open their sprinkler systems. Properly de-winterizing and prepping your irrigation system ensures a healthy lawn and prevents costly plumbing repairs. Here’s a step-by-step guide on when and how to safely open your sprinklers this spring.

When Should I open my Sprinklers in Denver?

The best time to open your sprinkler system depends on the local climate. In Denver, we typically experience the last frost between mid-March and early April. To avoid potential pipe damage from unexpected freezes, it’s recommended to wait until temperatures consistently stay above 32°F, usually by mid-to-late April.

If you open your system too early, lingering cold snaps could cause pipes to freeze and crack. On the other hand, waiting too long can lead to dry patches on your lawn as the growing season begins. The key is to monitor the forecast and aim for a stretch of warm, frost-free nights before calling to get your sprinklers opened.

Steps to Safely Open Your Sprinkler System

1. Inspect the System for Damage

   • Before turning on the water, walk around your yard and inspect the sprinkler heads, valves, and exposed pipes. Look for any cracks, leaks, or damage caused by winter weather. If you notice any issues, contact us for irrigation help.

2. Slowly Turn On the Main Water Supply

   • Locate the main shutoff valve for your sprinkler system and turn it on slowly. This gradual process helps prevent sudden pressure surges that can cause pipes to burst.

3. Check for Leaks and Proper Water Flow

   • Run a test cycle and examine each sprinkler zone. Look for any signs of leaking, pooling water, or weak pressure. If you notice inconsistent watering, you may have a clog or broken valve that needs fixing.

4. Adjust Sprinkler Heads

   • Ensure each sprinkler head is properly aligned and distributing water evenly across your lawn. Misaligned or clogged heads can waste water and create dry spots.

5. Set Your Irrigation Schedule

   • In Denver, spring rainfall can vary, so adjust your watering schedule based on weather conditions. A good starting point is to water your lawn two to three times a week in the early morning to prevent evaporation.

   
   

Spring Lawn Prep Tips for a Healthy Yard

Beyond opening your sprinklers, here are a few additional steps to prepare your lawn and plumbing system for the warmer months:

• Clear Debris: Rake up leftover leaves, twigs, and winter debris to prevent clogs in drainage areas and irrigation lines.

• Aerate Your Lawn: This allows water and nutrients to reach the grass roots more effectively.

• Check Outdoor Faucets & Hoses: Inspect your hose bibs and outdoor spigots for winter damage, as frozen pipes can lead to leaks.

• Inspect Your Home’s Plumbing: Spring is a great time to check for any leaks, slow drains, or plumbing issues that may have developed over winter.
