Watering in October? Read This First.

Some homeowners choose to continue watering into October. In certain conditions, this can be beneficial—but it requires caution as freezing temperatures become more likely.

If you plan to water late into the season:

• Wrap the backflow preventer with insulation and cover it with a plastic bag secured with tape.
• Remember that this provides limited protection and does not guarantee against freeze damage.

The safest approach is to schedule your sprinkler winterization and blowout before freezing temperatures arrive.

Why Professional Winterization Matters

An improper sprinkler blowout—or skipping winterization altogether—can lead to:

• Cracked pipes underground

• Damaged valves and fittings

• Broken sprinkler heads

• Costly and avoidable spring repairs

Our team winterizes thousands of systems each year and understands how Colorado’s climate impacts irrigation equipment. The goal is simple: protect your system so it’s ready to perform next season.
