Mississauga Irrigation Winterizing - What You Need To Know?

The best time to winterize your irrigation system is in the fall, before the first hard frost. Typically, this means October or early November in Mississauga. Don’t wait until it’s freezing cold, as water left in the system can cause damage.

Locate the main water supply valve for your irrigation system and turn it off. This is usually located in a basement or utility room. Make sure to also shut off any secondary shut-off valves or backflow preventers in your system.

To prevent water from freezing in the pipes and causing damage, you need to completely drain the system. You can do this by opening all the drain valves and drain plugs in your irrigation system. This includes any low points in the system where water might collect.

The most effective way to remove all remaining water from the system is by blowing it out with compressed air. This is typically done by hiring a professional irrigation service. They will use an air compressor to force air through the pipes, pushing out any water. This step is crucial to prevent freezing and cracking of the pipes.

If you have above-ground components like backflow preventers, valves, or above-ground piping, it’s a good idea to insulate them. Specialized insulation covers or foam can be used to protect these components from freezing temperatures.

If you have any removable parts, such as sprinkler heads or hoses, remove and store them indoors for the winter. This prevents damage from freezing and extends their lifespan.

Perform routine maintenance checks throughout the year to ensure your system is in good working order. Address any repairs or issues promptly to avoid larger problems down the line.

While some homeowners may attempt winterization themselves, it’s often safer and more effective to hire a professional irrigation service. They have the experience, tools, and knowledge to ensure your system is properly winterized.

Keep records of your winterization activities, including the dates and steps taken. This can help you keep track of maintenance and ensure nothing is overlooked.

Once winter is over, don’t forget to schedule a spring startup for your irrigation system. This involves turning the water supply back on, checking for any damage or leaks, and adjusting the system as needed.
