Step 1: Turn Off the Water Supply

The first step to blow out the sprinkler system is turning off the water supply. This is crucial to prevent any more water from entering the system while you work.

Shut Off the Water

Locate the isolation valve for your sprinkler system. This valve is usually found near your main water line. Once you find it, turn it off completely. This action stops any new water from flowing into your irrigation system.

Open Hose Bibs

Next, you need to release any water that’s already in the pipes. Find the hose bib, which is often located outside your house, before the backflow preventer. Place a bucket underneath and open the hose bib. This will let the water drain out.

Tip: Hose bibs can sometimes be found inside, especially in colder regions, so check both indoors and outdoors.

Drain the Water

After opening the hose bib, let the remaining water drain from the main sprinkler line. This step ensures that your system is free of water, reducing the risk of freezing during winter.

Once you’ve completed these tasks, your system is ready for the next steps in the blow-out process. By following these steps, you’re taking the first crucial action towards protecting your sprinkler system from winter damage.

Step 2: Prepare Your Equipment

Before you blow out the sprinkler system, gather the necessary tools and gear to ensure a smooth process. Proper preparation can make all the difference in protecting your irrigation system.

Air Compressor

Choose an air compressor that is powerful enough for the job. You’ll need a model that can produce air at a volume of at least 30 to 50 cubic feet per minute (cfm) and pressures of 40 to 80 PSI. This ensures that the compressor can effectively clear all the water from your pipes without causing damage.

Tip: For PVC piping, do not exceed 80 PSI, and for polyethylene piping, keep it under 50 PSI to prevent any potential damage.

Safety Glasses

Safety first! Wear protective goggles to shield your eyes from debris that might be dislodged during the blow-out process. Compressed air can mobilize dirt, leaves, and other particles, so it’s important to protect your eyes at all times.

Coupler

A coupler is essential for connecting the air compressor to your sprinkler system. Make sure you have the right coupler that fits both your air compressor and the irrigation system. If the fittings don’t match, you may need an adapter to ensure a snug connection.

Pro Tip: An air compressor blow-out adapter, commonly used for winterizing RVs, can be a handy tool for this task.

Once your equipment is ready, you’re all set to move on to the next step, where you’ll connect the air compressor to your irrigation system. This preparation ensures that the blow-out process will be efficient and effective, keeping your sprinkler system safe through the cold months.

Step 3: Connect the Air Compressor

Now that your equipment is ready, it’s time to connect the air compressor to your sprinkler system. This step is crucial for ensuring a successful blow-out.

Attach the Hose

First, attach the air hose to your compressor. Make sure it’s long enough to reach your sprinkler system easily. A flexible hose is best, as it allows for easier maneuvering around your yard.

Check for leaks: Before proceeding, inspect the hose for any cracks or air leaks. A leak can reduce air pressure and make the blow-out less effective.

Use a Blow-Out Adapter

Next, you’ll need a blow-out adapter to connect the air hose to your sprinkler system. This adapter is essential because most sprinkler systems aren’t designed to connect directly to an air compressor.

Tip: If the adapter doesn’t fit snugly, you may need a quick-connect coupling to bridge the gap. This ensures a secure connection and prevents air from escaping.

Ensure a Secure Fit

Once the hose and adapter are in place, double-check the connections. Everything should be tight and secure. A loose connection can lead to air leaks, which will weaken the blow-out process.

Remember: A secure fit is crucial for maintaining the air pressure needed to clear water from the system effectively.

By carefully connecting your air compressor, hose, and adapter, you’re setting the stage for a successful blow-out. This step ensures that your system will be free of water and ready to withstand the winter freeze.

With the connections secure, you’re now ready to move on to the exciting part—blowing out the sprinkler system zone by zone.

Step 4: Blow Out the Sprinkler System

Now that everything is connected, it’s time to blow out the sprinkler system. This part is crucial for removing all the water, protecting your pipes from freezing and cracking during winter.

Gradual Pressure Increase

Start by turning on your air compressor slowly. Gradually increase the pressure until you reach the recommended PSI for your system. This is typically between 40 to 80 PSI, depending on your pipe type. For PVC piping, you can go up to 80 PSI, but for polyethylene, keep it below 50 PSI to avoid damage.

Important: Never exceed these limits. Too much pressure can burst your pipes and cause costly repairs.

Zone-by-Zone Approach

Once the compressor is running, begin with the zone farthest from the mainline. This ensures that all water is pushed out effectively. Open the valves for this zone and watch as the water sprays out. Wait until you see only air coming through before moving to the next zone.

Repeat this process for each zone, working your way closer to the main water line. Each zone should take about two minutes, but it’s crucial to ensure that the spray turns to air before moving on.

Tip: If your system is on uneven terrain, start with the higher zones first. They may require higher pressure to clear out all the water.

Monitor PSI

Keep a close eye on the PSI gauge throughout the process. Monitoring the pressure ensures that it remains within safe limits. If you notice the pressure dropping or rising unexpectedly, pause and check for leaks or blockages.

Remember: Safety first. Always wear safety glasses and keep bystanders away from the area to avoid accidents.

By following these steps, you can effectively blow out each zone, ensuring your sprinkler system is ready for winter. Once you’ve finished with all the zones, it’s time to finalize and inspect your work.

Step 5: Finalize and Inspect

With all zones cleared of water, it’s time to wrap up the process and ensure everything is in order. This final step is essential to confirm your sprinkler system is ready for the winter months.

Release Air Pressure

First, turn off the air compressor. Then, slowly release any lingering air pressure by opening the backflow device valves a couple of times. This helps to avoid any trapped air pockets that might cause issues later on.

Close Valves

Next, close all the valves you opened during the blowout. This includes the shut-off valve on the compressor and any backflow device valves you used. Closing these valves prevents water from accidentally entering the system and freezing during the cold months.

Check for Leaks

Now, take a moment to inspect your system for any leaks. Walk around and visually check the sprinkler heads, pipes, and connections. Look for water drips or any signs of moisture. If you spot a leak, address it promptly to avoid damage.

Quick Tip: If you notice any parts that seem worn or damaged, consider replacing them before spring. This proactive step can save you from headaches when it’s time to reactivate your system.

By finalizing and inspecting your sprinkler system, you ensure it’s thoroughly prepared for winter. This careful attention to detail helps prevent costly repairs and ensures your system will work flawlessly when warmer weather returns.
