When to Blow Out Sprinklers in Denver?

In Denver, it’s crucial to blow out your sprinkler system to prevent freezing and potential damage as temperatures drop. Generally, the best time to schedule sprinkler blowout in Denver is between mid-September and late October, before the first hard freeze of the season.

Failing to properly winterize your sprinkler system can lead to cracked pipes, broken sprinkler heads, and costly repairs.

Why Blow Out Your Sprinklers in Denver?

Denver’s climate is characterized by significant temperature fluctuations and freezing temperatures during the winter months. Water left in sprinkler lines can freeze and expand, causing pipes to burst and damage sprinkler heads. A professional blowout removes this water, protecting your system from costly repairs.

Determining the Right Time

Several factors influence the best time to blow out your sprinklers:

Monitor the Weather Forecast

Pay close attention to long-range weather forecasts. Look for consistent overnight temperatures dropping below freezing (32°F or 0°C). Don’t wait until the first freeze is already upon you.

Consider Elevation and Microclimates

Denver’s elevation and varied topography can create microclimates. Areas at higher elevations or those prone to colder temperatures may need to be winterized earlier than lower-lying areas.

Check Your Sprinkler System Type

Some sprinkler systems are more susceptible to freeze damage than others. Systems with shallow pipes or those lacking proper insulation should be blown out earlier in the season. You can learn more about sprinkler irrigation on Wikipedia.

The Blowout Process

A professional sprinkler blowout typically involves using a high-powered air compressor to force water out of the pipes. This process requires specialized equipment and knowledge to avoid damaging the system. Attempting a DIY blowout without the proper tools and expertise can be risky.

What Happens If I Wait Too Long?

Delaying the blowout can lead to significant damage. If water freezes in the pipes, it can cause cracks and breaks that require costly repairs in the spring. You may also experience issues with sprinkler heads that are cracked and will need to be replaced.

FAQs

When is the absolute latest I can blow out my sprinklers?

While ideally done before, you might be able to get away with a blowout in early November, *if* temperatures haven’t been consistently freezing. However, this is risky and not recommended.

Can I blow out my sprinklers myself?

Yes, but only if you have the correct type of air compressor and know what you are doing. Sprinkler systems can be damaged if incorrect procedures are followed.

How much does it cost to blow out sprinklers in Denver?

The cost varies depending on the size of your system and the contractor, but expect to pay between $75 and $200.

What happens if I don’t blow out my sprinklers?

You risk frozen and burst pipes, damaged sprinkler heads, and costly repairs in the spring.

Besides blowing them out, what else can I do to winterize my sprinkler system?

Insulating exposed pipes and sprinkler heads can provide extra protection. Also, consider turning off the main water supply to your sprinkler system.

Summary

Winterizing your sprinkler system is a necessary task for Denver homeowners. By scheduling a blowout between mid-September and late October, and by monitoring weather conditions, you can protect your irrigation system from freeze damage and ensure it’s ready to use again in the spring.
