Keeping your sprinkler system in tune with the seasons is key to avoiding costly repairs and keeping your landscape vibrant year-round. In Ontario’s climate, timing is everything when it comes to opening and closing your system. Here’s what you need to know about properly winterizing and reopening your sprinkler system to keep it working properly.
When to Close Your Sprinkler System in Ontario
Winterizing your sprinkler system is a must before the first hard freeze, usually in late fall. In Southern Ontario, temperatures start to dip consistently below freezing by mid-November. Before this is the ideal time to drain the lines, blow out the remaining water, and ensure no trapped moisture remains that could expand and damage pipes when temperatures drop.
To close down your system, follow these steps:
- Turn Off the Water Supply: Shut off the water at the main valve to prevent additional water from entering the system.
- Drain the Lines: Use the manual drain valve or air compressor to clear out any remaining water. It’s crucial to avoid leaving any trapped water that could freeze and expand.
- Insulate Exposed Pipes: Wrap exposed valves or pipes to protect them from freezing temperatures.
When to Reopen Your Sprinkler System in Spring
As spring arrives, it’s time to prepare your sprinkler system for the warmer months. In Ontario, the best time to reopen your system is typically in mid-April, once the risk of frost has passed. Opening your system too early can expose it to late-season freezes, which can cause costly damage.
Steps to Reopen:
- Inspect for Damage: Before turning the water back on, check for any visible damage to pipes, valves, and sprinkler heads that may have occurred over winter.
- Turn on the Water Supply Gradually: Open the main valve slowly to prevent water hammer, which can damage pipes and sprinkler components. Allow the water to flow through each zone to ensure it’s running correctly.
- Run a Test Cycle: Activate each zone manually to verify that all sprinkler heads are functioning and adjusted properly. If you notice any irregular spray patterns or leaks, make repairs before the system goes fully operational.
Tips for Sprinkler Maintenance
- Check System Pressure: Maintaining the correct water pressure is crucial for efficient watering. High pressure can lead to wear and tear on your system, while low pressure may lead to ineffective coverage.
- Adjust for Season: Consider adjusting your system’s timer and spray heads for seasonal needs to avoid over-watering in cooler months.
- Schedule a Professional Inspection: Having a professional check your system annually helps ensure all components are in top condition, saving you from unexpected repairs.
