Should You Turn Off Your Sprinkler System When You Go on Vacation? Ottawa Homeowner’s Guide
Planning a vacation? Don’t forget about your lawn!
Leaving home for several days or weeks doesn’t mean your lawn and garden should be forgotten. During warm weather, your grass, flowers, and shrubs may still need water while you’re away.
An automatic sprinkler system can help maintain your landscaping while you’re travelling. However, leaving your irrigation system running on its normal schedule without checking it first can lead to wasted water, overwatering, or unexpected leaks.
For homeowners in Ottawa and surrounding areas, preparing your sprinkler system before leaving home can help protect your landscaping and provide peace of mind.
In this guide, we’ll explain how to prepare your residential irrigation system before a vacation, what settings to check, and how to avoid common watering problems while you’re away.
1. Should You Turn Off Your Sprinkler System Before Leaving?
The answer depends on the season, the weather forecast, and how long you’ll be away.
If you’re travelling during the growing season, completely shutting off your sprinkler system may leave your lawn without enough water during hot, dry weather.
On the other hand, leaving your normal watering schedule unchanged could waste water if substantial rainfall occurs while you’re away.
Before leaving, consider the following:
* How long will you be away?
* Is hot, dry weather expected?
* Has your lawn received sufficient rainfall?
* Does your irrigation system have a functioning rain sensor?
* Are your plants established or newly planted?
* Is your sprinkler system operating correctly?
For a short trip, your existing watering schedule may be adequate. For a longer vacation, reviewing your irrigation settings is especially important.
The goal is to provide enough water to maintain your landscaping without unnecessary irrigation.
2. Check Your Sprinkler Controller Before You Leave
Your irrigation controller determines when each sprinkler zone operates and how long it runs.
Before leaving home, make sure the controller is programmed correctly.
Check these important settings:
Confirm the Watering Days
Make sure your sprinkler system is scheduled to water on the intended days.
If you’ve recently adjusted your watering schedule, verify that the changes were saved correctly.
Check the Start Times
Some irrigation controllers allow multiple start times each day.
An incorrectly programmed controller can cause zones to run more often than intended.
Check that you haven’t accidentally programmed duplicate start times.
Review the Run Times
Different zones may require different watering durations depending on the sprinkler heads, soil conditions, and landscaping.
Avoid increasing all watering times simply because you’ll be away.
Instead, use a schedule appropriate for your lawn and garden.
Check the Date and Time
A controller with an incorrect clock may run its programmed schedule at the wrong time of day.
Confirm that the date, time, and watering schedule are correct before leaving.
3. Make Sure Your Rain Sensor Is Working
If your irrigation system has a rain sensor, check that it is connected and functioning properly.
A rain sensor can suspend scheduled watering when sufficient rainfall has occurred, helping prevent unnecessary irrigation while you’re away.
However, remember that a rain sensor generally detects rainfall rather than measuring moisture throughout your lawn’s root zone.
A light shower may not provide enough water for your lawn, while heavier rainfall may eliminate the need for additional irrigation.
Before travelling, check that:
* The sensor is properly connected.
* The controller recognizes the sensor.
* The sensor is positioned appropriately.
* The controller’s sensor settings are correct.
* The system responds as expected when the sensor is activated.
If your rain sensor isn’t working, consider having it inspected before leaving.
4. Inspect Your Sprinkler System for Leaks
One of the most important things to do before a vacation is to make sure your irrigation system isn’t leaking.
A small problem that goes unnoticed while you’re home could continue for days while you’re away.
Before leaving, run your sprinkler zones and inspect the system.
Look for:
* Water pooling around sprinkler heads.
* Sprinklers that continue running after their zone shuts off.
* Broken sprinkler heads.
* Water spraying onto driveways or sidewalks.
* Wet areas around valve boxes.
* Unusual changes in sprinkler pressure.
* Water flowing where it shouldn’t.
If you notice a leak or malfunction, arrange for the necessary irrigation repair before your trip.
Don’t assume a small leak will remain small. An irrigation system that operates automatically can continue wasting water until the problem is corrected.
5. Adjust Watering for Ottawa’s Weather
Ottawa weather can change considerably throughout the growing season.
A watering schedule that works during a hot, dry period may provide too much water during cooler or rainy conditions.
Before leaving, consider the expected weather and the current condition of your lawn.
If rain is forecast, a functioning rain sensor or suitable controller adjustment may reduce unnecessary watering.
If hot, dry weather is expected, your lawn may need its normal watering schedule to continue.
Avoid making major changes based only on the forecast. Weather predictions can change, and different parts of your property may have different watering requirements.
The best approach is to start with an appropriate watering schedule and use available weather information to make sensible adjustments.
6. Don’t Forget Your Garden Beds and Newly Planted Shrubs
Your lawn isn’t necessarily the only part of your property that needs attention.
Flower beds, shrubs, vegetable gardens, and newly planted trees may have different watering requirements from established grass.
For example, newly planted shrubs may need closer attention during hot weather because their root systems haven’t fully established.
Before leaving, consider whether your existing irrigation system provides appropriate coverage for these areas.
If you use drip irrigation for garden beds, inspect the tubing and emitters to make sure water is reaching the intended plants.
Avoid assuming that watering your lawn automatically provides sufficient moisture to every garden bed.
7. Should You Leave Your Sprinkler System Running While You’re Away for Weeks?
For an extended vacation during the growing season, an automatic irrigation system can be useful.
However, the longer you’re away, the more important it becomes to ensure the system is operating correctly.
Before leaving for several weeks:
1. Run and inspect every irrigation zone.
2. Check the controller programming.
3. Confirm that the rain sensor is working.
4. Inspect exposed pipes, fittings, and valve boxes for leaks.
5. Make sure sprinkler heads are distributing water properly.
6. Review the watering schedule for the expected weather.
7. Consider asking someone to check the property periodically.
If you have a smart irrigation controller, you may also be able to monitor or adjust the schedule remotely, depending on the model and its features.
Remote access is helpful, but it doesn’t replace checking the system for physical leaks or damaged components.
8. What If You’re Leaving Ottawa in the Fall or Winter?
Seasonal timing makes a significant difference.
During the growing season, your sprinkler system may need to continue watering your lawn while you’re away.
However, Ottawa homeowners must also prepare their irrigation systems for freezing temperatures in the fall.
If you’re leaving for an extended period during the fall, don’t rely on your normal watering schedule without considering the weather.
Before sustained freezing conditions arrive, your underground irrigation system should be properly winterized.
Once the system has been winterized, don’t restart it simply because the weather becomes temporarily warmer. Water remaining in the system can create problems if freezing temperatures return.
If you’re travelling during the fall and haven’t arranged winterization, consider scheduling the service before you leave.
Planning ahead can help prevent freeze damage and the possibility of unexpected repairs when spring arrives.
9. What to Do When You Return Home
After returning from vacation, take a few minutes to inspect your lawn and irrigation system.
Look for dry patches, unusually wet areas, damaged sprinkler heads, or other signs that the system may not have operated as expected.
If your controller has a watering history or system alerts, review them if available.
You may also want to run the affected zones to confirm that the system is still working correctly.
If you notice poor coverage, leaking components, or zones that aren’t operating properly, have the problem investigated before making major changes to your watering schedule.
Common Mistakes to Avoid Before Going on Vacation
A little preparation can help prevent unnecessary irrigation problems.
Avoid these common mistakes:
Turning off the system without considering the weather: Your lawn may still need water during a hot, dry period.
Leaving the controller unchecked: Incorrect start times or run durations can cause unnecessary watering.
Ignoring a malfunctioning rain sensor: Your system may continue watering after substantial rainfall.
Overwatering as a precaution: Increasing watering times unnecessarily can waste water and leave the lawn too wet.
Ignoring small leaks: A damaged sprinkler head or leaking valve can continue wasting water while you’re away.
Forgetting fall winterization: An irrigation system that hasn’t been properly prepared for freezing weather may suffer costly damage.
Taking these precautions before leaving can help keep your irrigation system working as intended.
