How to Prevent Your Sprinkler System From Freezing

According to research, 92% of Canadians think a yard adds value to a property.

A lawn sprinkler plays a vital role in keeping a beautiful lawn on your property. However, as temperatures begin to drop, homeowners in Oakville must prepare for winter.

Freezing temperatures can wreak havoc on irrigation systems, leading to costly repairs. Thus, winterizing your sprinkler system is crucial for its longevity and functionality.

Read on and learn how to winterize your sprinkler system.


Shutting Off the Water Supply

Shut off the water supply. This prevents water from entering the system during the freezing months. Ensure the shut-off valve is turned off correctly. This simple step is a critical measure in safeguarding your system against freezing damage.

Drain all water from the pipes, valves, and sprinkler heads. Water left in the system can freeze, expand, and cause cracks or bursts in the pipes. The draining method depends on your system type.

Drain Water


There are mainly three styles of draining water :

1. Manual Drain Systems

These systems require you to manually open the valves to drain water from the pipes. After shutting off the water supply, open these valves to allow water to flow out. This method is usually used in regions with mild winters, where the ground doesn't freeze deeply.

2. Auto Drain Systems

These are designed to automatically expel water from the pipes when the pressure drops below a certain level. Additional manual draining might be necessary if the auto drains don't fully evacuate all water.

3. Blow-Out Systems 

Blow-out systems are ideal for areas with harsh winter conditions. They use an air compressor to blow air through the sprinkler water pipes, pushing out any remaining liquid. It's often recommended to have a professional perform this method, as incorrect air pressure can cause significant damage to the system.


Insulating Components

Any above-ground components, such as valves and backflow preventers, need insulation to protect them from freezing temperatures.

Insulation tape or foam insulating covers are effective ways to shield these components. Proper insulation is vital to prevent any exposed parts from freezing and cracking. A professional irrigation technician can install freeze-resistant pipes, protecting your sprinklers from unexpected cold spells that freeze deep.
