How to use irrigation sprinkler compressor for blowout?

Using an irrigation sprinkler compressor for blowout in the GTA and Toronto is required, in order to prevent freeze damage in the winter, because Toronto winters can be hard, with freezing temperatures. To blow out your irrigation system, connect an air compressor (minimum 50 CFM at 80-100 PSI) to the system’s blowout port. Start by shutting off the water valve, then gradually introduce air through the zones, beginning with the furthest one. Continue until only air exits the sprinklers. To avoid the common mistakes  let’s discuss it.

How to chose the right sprinkler compressor for blowout?

To choose the right compressor for proper blow out of your irrigation system, you’ll need a high-quality air compressor with a minimum output of 50 cubic feet per minute  at a pressure range of 80-100 pounds per square inch. This ensures that there is plenty of air volume to efficiently clear water from the lines without causing any damage!. Along with the compressor, you’ll need the appropriate fittings and adaptors to connect it securely to your system’s blowout port, typically involving a quick-connect coupling or threaded adaptor depend on your system’s design. Don’t forget about safety is also important during this process! Always wear safety goggles to protect your eyes from debris and gloves to handle equipment safely. Additionally, hearing protection is advisable since compressors can be quite loud. Having the right tools and equipment will make the blowout process efficient and safe, preventing any water from remaining in the system and causing freeze damage during winter.

Common mistakes to avoid during irrigation system blowout

When performing an irrigation system blowout, avoiding common mistakes is crucial for a successful winterization. One of the biggest mistakes is using incorrect pressure—too high PSI can damage pipes and sprinkler heads, while too low PSI won’t effectively clear the water, leaving your system vulnerable to freezing. Another common mistake is not fully draining the system; any remaining water can expand when it freezes, leading to cracked pipes and costly repairs. It’s also essential to address every zone during the blowout. Skipping zones might seem like a time-saver, but it can leave parts of your system at risk of freezing. Make sure to use the right pressure, fully drain the system, and cover all zones to keep your irrigation system safe during winter. This way, it’ll be good to go once the weather gets warmer!
