Winterizing Your Sprinkler System Without Blowout: An Effective Alternative Approach

When the fall season arrives, winterizing sprinkler systems becomes a crucial task to prevent potential damage caused by freezing temperatures. While the traditional method often involves a blowout using an air compressor, there's an alternative approach that can be just as effective.

In this article, we will explore the process of winterizing your sprinkler system without blowout, offering valuable insights and steps to protect your irrigation system during the winter months.

The Alternative Approach: Winterizing Sprinkler Systems without Blowout

Winterizing your sprinkler system without a blowout can be a viable option for certain setups. If your winterization requirements align with specific criteria, this approach might be an ideal solution. By considering this alternative, you can avoid the need for an air compressor blowout while still safeguarding your system.

Steps to Winterize Without Blowout

  1. Turn Off the Water Supply

The first step in winterizing your sprinkler system without blowout is to locate and shut off the main water supply valve. This ensures that no additional water enters the system during the winterization process.

  1. Open Drain Valves

For this method to be effective, open the drain valves at the end of each zone on your sprinkler system. Allowing the water to drain out through these valves helps minimize the risk of freezing and potential pipe damage.

  1. Safeguard the System

To provide extra protection, properly insulate exposed pipes with pipe insulation. This acts as a barrier, retaining heat and reducing the chances of freezing during winter.

  1. Cover Backflow Preventer and Sprinkler Heads

The backflow preventer is a vital component that requires special attention. Make sure to insulate it using a commercial cover or foam pipe insulation. Additionally, cover sprinkler heads with protective covers or use towels and burlap sacks to shield them from debris and freezing temperatures.

  1. Store Hoses and Mark the System's Location

Disconnect hoses and store them in a dry and sheltered place for the winter to prevent damage. For systems buried underground, it's essential to mark their location to avoid accidental damage during winter activities.

Why the Blowout Method Remains Popular

Although winterizing sprinkler systems without blowout can be effective for some setups, it may not fully remove all water from the pipes. That's why many experts still recommend the blowout method using an air compressor as the most reliable way to ensure the system is clear of any water. A thorough blowout significantly reduces the chances of frozen pipes and potential damage.


As you embark on winterizing your sprinkler system for the colder months, consider the most suitable method for your specific setup. While winterization without blowout may be suitable for certain systems, it might not be as comprehensive as a full blowout using an air compressor. However, by following the alternative approach outlined in this article, you can effectively protect your sprinkler system during winter. Whether you choose the blowout method or the alternative approach, proper winterization ensures your irrigation system remains in top shape and ready to perform optimally when spring arrives.
