Sprinkler Blowouts - Precision Backflow

Sprinkler Blowouts

Each year before the first freeze, the ritual of winterization for sprinklers, also known as the irrigation system maintenance 'blowout,' becomes a priority for all irrigation systems in areas where frost levels extend below the depth of the installed piping. We offer professional sprinkler blowout services for both residential and commercial customers.

Why Should you have your Sprinklers Blown Out?

In regions where temperatures can dip below freezing for extended periods, proper irrigation system maintenance is crucial. Every exterior lawn sprinkler system must undergo winterization for sprinklers, which includes blowing out the system and shutting it down at the end of the season. This process ensures that the harsh winter and freezing temperatures do not harm the components and piping of your lawn sprinkler system. It is essential that this service is performed by a trained lawn sprinkler technician utilizing specialized equipment.


At Precision Backflow, we are trained in the correct procedures to winterize and blow out any size underground lawn sprinkler, garden, or drip irrigation system. Our equipment is regulated to deliver the precise amount of compressed air per manufacturer specifications, effectively removing residual water from all main lines, lateral lines, manifolds, and solenoid valves. When executed properly, this process prevents damage to the sprinkler heads, solenoid valves, and piping due to excess pressure or friction from an improperly regulated air compressor.


If the winterization process is not performed correctly, you may face damage to the irrigation system, which will become evident when the sprinkler system is restarted in the spring. This highlights the importance of avoiding seasonally advertised “SPECIAL” offers for this service. In the end, you could end up spending more on repairs caused by a “DIY guy” or a handyman who lacks the necessary licensing, insurance, training, or equipment.


When winterized correctly, your lawn sprinkler system will be prepared to handle whatever Mother Nature has in store over the winter season. As spring arrives and temperatures rise, you can count on the friendly and knowledgeable staff at Precision Backflow to be ready to assist with all your irrigation system maintenance needs once again.

What to Expect from the Precision Backflow Team?

1) A Precision Backflow technician, arriving in a trademarked service vehicle, will be at your home within the time window for your scheduled appointment. Equipped with the proper tools and expertise, they will efficiently handle the winterization for sprinklers, ensuring your home's lawn and garden irrigation system is properly shut down and prepared for the cold season.


2) The main water service for your lawn sprinkler system or well supply will be safely disconnected or shut down.


3) A specially regulated air compressor will be connected to your irrigation system, charging it with the appropriate amount of forced air to facilitate irrigation system maintenance.


4) The technician from Precision will meticulously work through each zone, eliminating all residual water from both the main lines and lateral lines. During this process, a light mist or “whistling” sound will emit from the sprinkler heads, indicating that your irrigation lines have been effectively winterized.


5) A tag will be affixed to the main shut-off valve, warning anyone with a clear message of "DO NOT TOUCH"—confirming that the system has undergone winterization for sprinklers.


6) Any booster pumps, well lines, or filters will be drained, and all electrical sources will be shut down or disconnected as part of the irrigation system maintenance.


7) Once this service is completed, your irrigation water supply will be turned off for the season, and the control timer will be switched to the "rest" mode.

What Happens when you Winterize a Sprinkler System?

Winterizing an irrigation system is essential for effective irrigation system maintenance, as it safeguards yard irrigation systems from potential damage during the freezing winter months. Many people may not realize that failing to prepare their sprinklers, valves, and pipes for the harsh winter weather can result in a compromised sprinkler system by the time spring arrives. This oversight could lead to significant repair costs or even necessitate the replacement of the entire irrigation system.


When winterizing your yard sprinkler system, all water is removed from your sprinkler heads, pipes, and valves. This step is crucial because any remaining water can freeze during cold temperatures, leading to damage. When water freezes, it expands, which increases pressure within your sprinkler heads, pipes, and valves, possibly causing them to crack.


By employing winterization for sprinklers, you can prevent such damage from occurring. However, utilizing the blow out method to clear your system is not as straightforward as it might seem. Proper techniques must be followed to effectively clear sprinkler system pipes and heads for winterization, ensuring your system operates seamlessly when spring returns. For this reason, you should rely on professional sprinkler blowout services, such as those offered by Precision Backflow.
