Severe storms in Orillia and across Simcoe County can roll in fast — and when they do, most homeowners are focused on getting inside safely.
But while you’re watching the sky, your underground and above-ground irrigation system is quietly vulnerable to a range of storm-related damage that can cost hundreds, or even thousands, of dollars to repair. Every homeowner should know how to protect your sprinkler system during severe storms.
Don’t Let the Next Storm Destroy Your Sprinkler System
The good news? A little preparation goes a long way. Whether you’re dealing with a heavy thunderstorm, flash flooding, or the increasingly common severe wind events that sweep through Central Ontario, knowing exactly what to do before, during, and after a storm can protect your irrigation investment and keep your system running smoothly all season long.
At Clearwater Irrigation, we’ve helped Orillia homeowners maintain and protect their sprinkler systems for years. Here’s our complete guide to storm-proofing your system.
Why Severe Storms Are a Real Threat to Irrigation Systems
Most people don’t think of their sprinkler system as storm-vulnerable — after all, it’s mostly underground. But modern irrigation systems have several exposed and sensitive components that severe weather can damage quickly.
What’s Actually at Risk
- Above-ground sprinkler heads can be snapped off or cracked by flying debris, hail, or fallen branches.
- Backflow preventers are typically mounted above ground and are highly exposed to wind, debris impact, and flooding.
- Control panels and timers (often mounted on exterior walls or in garages) can be damaged by power surges, water infiltration, or physical impact.
- Underground pipes and fittings can shift or crack when soil becomes heavily saturated and unstable during flash flooding.
- Electrical components and wiring are vulnerable to lightning strikes, power surges, and water damage.
In tornado-risk situations — which are more common in Ontario than many residents realize — the risks multiply dramatically. Even an EF0 or EF1 tornado passing nearby can uproot landscaping, hurl debris across your yard, and compromise your entire irrigation layout.
Before the Storm: Proactive Steps to Protect Your Sprinkler System
The most effective storm protection happens before the clouds arrive. Here’s what to do when severe weather is in the forecast.
1. Shut Off Your Irrigation Controller
This is the single most important step. When a storm is approaching, manually turn off your irrigation controller or switch it to “rain mode” if your system supports it. Running your system during a storm is not only wasteful — it can cause pressure issues and leave your system exposed to electrical surges if lightning strikes nearby.
Pro tip: Many modern smart irrigation controllers (like Rachio or Hunter Hydrawise) have automatic weather-sensing features that pause watering during rain events. If your system doesn’t have this, it’s a worthwhile upgrade — ask the Clearwater Irrigation team about smart controller options.
2. Turn Off the Water Supply to Your Irrigation System
Locate your irrigation shut-off valve (usually near your main water supply or in your basement) and close it before a major storm. This protects against pressure surges and prevents water from being forced backward through your system if flooding occurs near your outdoor connections.
3. Protect Your Backflow Preventer
Your backflow preventer is one of the most exposed and expensive components of your system. Before a severe storm:
- Wrap it with an insulated cover or foam pipe insulation if hail is expected.
- Ensure the area around it is clear of loose objects that could become projectiles.
- If a tornado warning is issued, consider whether temporary physical shielding (like a weighted tarp or board) is feasible without creating a hazard.
4. Clear Debris From Your Yard
Loose patio furniture, garden tools, decorative stones, and planters become dangerous projectiles in high winds. Clearing your yard protects not just your sprinkler heads but your entire property.
5. Document Your System’s Current Condition
Take a quick walk around your yard and photograph your sprinkler heads, backflow preventer, and control panel. This takes five minutes and can be invaluable if you need to file an insurance claim after storm damage.

During the Storm: What You Should (and Shouldn’t) Do
Once a severe storm or tornado warning is active, your priority is personal safety — not your sprinkler system. However, there are a few things to keep in mind.
Stay Inside and Away From Windows
Do not go outside to check on your irrigation system during a storm. No sprinkler head is worth your safety. If a tornado warning has been issued for the Orillia area, move to your basement or an interior room on the lowest floor of your home.
Avoid Touching Electrical Components
If you didn’t shut off your controller before the storm started, do not attempt to access it during active lightning. Wait until the storm has fully passed.
Monitor for Flooding Near Your Meter and Shut-Off
If you notice water rising near your home’s foundation or utility connections, and it’s safe to do so, shutting off your main water supply (not just irrigation) may be appropriate. This is a judgment call based on the severity of flooding.
After the Storm: Your Post-Storm Inspection Checklist
Once the storm has passed and it’s safe to go outside, a thorough inspection of your irrigation system is essential. Catching damage early prevents small issues from becoming expensive repairs.
Post-Storm Irrigation Inspection Checklist
Sprinkler Heads
- Walk the full perimeter of your irrigation zones and visually inspect each head.
- Look for cracked, broken, or missing heads — these are common after hail or debris impact.
- Check for heads that are no longer flush with the ground, which can indicate soil shifting.
Backflow Preventer
- Inspect for cracks, dents, or physical damage.
- Check that all valves are still properly aligned and haven’t been knocked out of position.
- Look for signs of leaking or water pooling around the unit.
Control Panel and Wiring
- Check your controller for error messages or blank screens, which can indicate a power surge or water infiltration.
- Inspect visible wiring for damage, especially any that runs along exterior walls or through conduit near ground level.
- Reset your controller if needed and run a manual test cycle to verify all zones are functioning.
Underground Lines
- After heavy rain or flooding, run each zone briefly and walk the area while it’s running.
- Look for unusually wet patches, sinkholes, or areas where water is bubbling up — these can indicate a broken underground line.
- Soft or sunken soil along your irrigation line path is another warning sign.
Drainage and Pooling
- Ensure your system’s drainage is functioning properly and that water isn’t pooling near your backflow preventer or controller.

Special Considerations for Tornado Warnings in Ontario
Many Ontario residents are surprised to learn that tornadoes are a genuine risk in this region. Environment Canada issues tornado watches and warnings for Simcoe County and the surrounding area multiple times each summer season. Here’s what makes tornado preparedness different from standard storm prep for your irrigation system.
Expect the Unexpected
A tornado doesn’t just bring wind — it brings airborne debris, soil displacement, uprooted trees, and in severe cases, structural damage to outbuildings and fences that sit directly above or beside your irrigation lines. After a tornado event:
- Assume your system has damage until you’ve completed a full inspection.
- Don’t run your system until you’ve verified that all zones are intact — a broken line underground can erode your landscaping and waste enormous amounts of water undetected.
- Call a professional for a comprehensive post-tornado assessment. This isn’t a DIY situation after a significant event.
Insurance Documentation
After tornado damage, your homeowner’s insurance may cover irrigation system repairs depending on your policy. The photos you took before the storm (as recommended above) will be critical. Ask your insurance provider specifically about irrigation and landscaping coverage.
Long-Term Storm Protection: Upgrades Worth Considering
If your irrigation system has been through a few rough seasons, it may be time to consider some upgrades that offer built-in storm resilience.
Smart Controllers With Weather Integration
Modern smart irrigation controllers automatically pause or adjust watering schedules based on real-time weather data. They can detect incoming storms and shut down your system automatically — even if you’re not home.
Surge Protection for Your Controller
An inexpensive surge protector installed at your irrigation controller can prevent costly electrical damage from nearby lightning strikes. This is one of the most cost-effective upgrades available.
Backflow Preventer Covers and Enclosures
Insulated, lockable enclosures for backflow preventers protect against both physical impact and temperature extremes. They’re especially valuable in a region like Orillia where weather swings can be dramatic.
Pressure Regulation Upgrades
Storm-related pressure surges can damage your system from the inside. Pressure-regulating heads and valves help buffer against these spikes.
