Steps to properly blow out a sprinkler system

When it comes to blowout a sprinkler system, there are few steps to follow. These steps are to prevent damage during the winter months. Here is a 3-step guide to help you:

  1. Prepare the Compressor: First, turn off the water supply and disconnect hoses/attachments. Then, locate the air intake valve and attach a hose. Make sure pressure is set for your system.
  2. Blow Out Each Zone: Close all valves except one zone. Turn on the compressor and let pressure build. Open one zone valve and observe the sprinkler heads. When no water is coming out, close the zone valve and move onto the next.

Don’t let a frozen sprinkler ruin your spring – winterize your system right! To help, here are key points to remember:

  1. Time it just right – don’t blow out too early or too late. Early could cause damage from frozen water, late may lead to frozen pipes and costly repairs.
  2. Disconnect all hoses and irrigation lines. Otherwise, water may accumulate and cause leaks and damage.
  3. Adjust air pressure carefully. Too much and pipes/heads could rupture, too little and water may remain.
  4. Don’t forget to drain all valves and cover all areas of the system. This way, you won’t get any surprises come spring.

Winterization tips to prevent sprinkler system damage

Winterizing your sprinkler system is a must to stop harm caused by freezing temps. Follow these 3 simple tips to ensure protection of the system during winter:

  1. Locate the main valve that supplies water to the system, and turn it off. This will stop any new water from entering.
  2. Open all drain valves and let the water fully leave the sprinkler lines. It’s important to remove all excess water, or it could freeze and cause damage.
  3. Use an air compressor or blower tool to remove trapped water in the pipes. Connect the tool to the sprinkler lines and blow out the left-over water. Make sure there are no clogs or obstructions.

You must also pay attention to details that may vary for your system. These include checking for leaks and cracks in pipes, insulating above-ground components, and protecting exposed outdoor valves from the cold.

Take action before temps drop below freezing or when you predict big temperature changes. Neglecting proper winterization could lead to costly repairs, or even irreparable harm to your sprinkler system.

Beat winter’s wrath by taking proactive measures now. Secure your investment and have peace of mind knowing your sprinkler system is safe against winter conditions. Don’t let winter catch you off guard!


When should you blow out your sprinkler system? It depends on factors like climate, type of irrigation system, and temps in your area. Consider these to prevent damage in winter.

Once temps stay below freezing, it’s critical to remove water from pipes. This is especially important in cold areas. Freezing water can burst pipes and cause costly repairs.

So, keep an eye on the weather forecast. Blow out your system when temps reach 32° F or lower. Follow the manufacturer’s guidelines, too. They may have different procedures or timings for winterizing. Consult a pro or read the owner’s manual for specific instructions. FYI: According to The Spruce website, blow out your sprinkler system before the first hard freeze.
