Shutting Down Your Sprinkler System for Winter: A Complete Guide
As temperatures begin to drop, preparing your landscape for winter is just as important as maintaining it throughout the growing season. One often-overlooked task is properly shutting down your sprinkler or irrigation system before freezing temperatures arrive.
Water left inside irrigation pipes, valves, or sprinkler components can freeze, expand, and potentially cause costly damage. Taking the time to winterize your system can help protect your irrigation equipment and ensure it is ready to operate when spring returns.
At 606 Land & Snow, we help homeowners and property managers prepare their landscapes for every season with professional lawn care, landscaping, seasonal cleanup, and snow removal services.
Know When to Shut Down Your Sprinkler System
Timing is important when preparing an irrigation system for winter. Ideally, your sprinkler system should be shut down before the ground begins to freeze and before sustained freezing temperatures arrive.
In Chicago and surrounding suburbs, fall weather can change quickly. Waiting until after a hard freeze may increase the risk of water remaining in exposed irrigation components.
Recommendation: Keep an eye on the seasonal forecast and plan your sprinkler shutdown before temperatures consistently reach freezing overnight.
Turn Off the Main Water Supply
The first step in winterizing most sprinkler systems is shutting off the water supply that feeds the irrigation system.
Locate the irrigation shut-off valve and turn off the water supply. Some systems have a dedicated shut-off valve near the backflow prevention device or where the irrigation line connects to the home's plumbing.
Once the supply is turned off, the system can be prepared for draining.
Important: If you're unsure which valve controls your irrigation system, consult a qualified irrigation professional rather than turning off the wrong water supply.
Drain Water From the Irrigation System
Simply turning off the water isn't always enough. Water can remain trapped inside irrigation pipes, valves, sprinkler heads, and other components.
Depending on the design of your system, water may be removed using one of several methods:
- Manual draining
- Automatic draining
- Compressed-air blowout
- A combination of drainage methods
The appropriate method depends on the type and configuration of the irrigation system.
Be Careful With Compressed Air
A compressed-air blowout can be an effective way to remove water from irrigation lines, but it should be performed carefully.
Using excessive air pressure can potentially damage sprinkler components, pipes, valves, or fittings. Different irrigation systems also have different requirements, so the equipment and pressure used should be appropriate for the system.
Recommendation: If you are not familiar with irrigation blowout procedures, consider having the system winterized by a qualified professional instead of attempting it yourself.
Protect Backflow Prevention Devices
Backflow prevention equipment is another important part of the winterization process.
Depending on the system, the backflow preventer may contain water that needs to be drained or otherwise protected from freezing temperatures.
Because backflow devices can vary significantly by system, homeowners should follow the manufacturer's instructions or have the equipment inspected by a qualified professional.
Shut Down the Irrigation Controller
Once the irrigation system has been properly drained, don't forget about the controller.
Depending on the model, you may be able to place the controller into an OFF, RAIN, or seasonal shutdown mode rather than completely disconnecting it.
This can help preserve programmed settings while preventing the system from activating unnecessarily during the winter.
Recommendation: Check the manufacturer's instructions for your specific controller before changing its settings.
Inspect Sprinkler Heads and Exposed Components
Winter preparation is also a good opportunity to inspect the visible parts of your irrigation system.
Look for:
- Cracked sprinkler heads
- Damaged or leaning heads
- Broken fittings
- Leaking valves
- Exposed pipes
- Damaged covers
- Signs of previous leaks
Addressing these issues before spring can make your system startup much easier.
Don't Forget Your Landscape
Winterizing your irrigation system is only one part of preparing your property for colder weather.
Fall is also an excellent time to take care of other seasonal landscaping tasks, including:
- Leaf and debris cleanup
- Lawn mowing before winter
- Garden bed cleanup
- Trimming and pruning
- Mulching
- Removing annual plants
- Preparing seasonal plantings
- Checking drainage areas
- Preparing outdoor features for winter
A complete fall cleanup can help your property enter winter in better condition and make spring maintenance easier.
Recommendations From 606 Land & Snow
Before temperatures drop, we recommend creating a simple winter preparation checklist for your property.
✔ Plan Ahead
Don't wait for the first major freeze. Schedule irrigation winterization early enough to avoid last-minute problems.
✔ Know Your System
Irrigation systems vary. Understand where your shut-off valves, backflow device, controller, and drainage points are located.
✔ Don't Force Components
If a valve, fitting, or sprinkler head is difficult to operate, avoid forcing it. Damaging the component can create a larger repair.
✔ Consider Professional Winterization
If you're unfamiliar with your irrigation system or compressed-air blowouts, professional assistance can help reduce the risk of accidental damage.
✔ Combine Seasonal Services
Fall is an ideal time to address multiple outdoor maintenance needs at once. Pair irrigation preparation with lawn care, trimming, garden cleanup, and other seasonal landscaping services.
Why Winter Preparation Matters
Properly preparing your sprinkler system can help reduce the possibility of freeze-related damage and make your irrigation system easier to restart in the spring.
A little preparation before winter can potentially save you from dealing with cracked components, leaks, unexpected repairs, and delayed spring landscaping.

What does "Mulch" mean?
Mulch is any material spread over the ground in a landscape setting. It is beneficial at any time of year. Still, it is helpful in the winter when cold winds and icy rains can damage your garden. This guide shows you how to prepare your plants for cold weather by mulching them with the best materials.
Why should you mulch for the winter season?
Getting your garden ready for winter means minimizing damage to plants by making them more resistant to cold. Mulch does this by putting a layer of insulation over your flower beds and vegetable garden.
Winter is the best time to mulch because your garden has fewer plants and weeds. It's the end of the growing season for many flowers and vegetables, so now is the perfect time to protect and improve the soil in your garden for next spring.
Tools for Winter Mulch
The Clemson Home & Garden Information Center suggests the following things to use as organic mulch:
- Wood chips - Wood chips are a good choice for gardeners on a budget because they are a cheap mulching material that keeps the soil moist and weeds from growing.
- Shredded hardwood - Try shreds of hardwood for a dense mulch that keeps weeds from growing and the soil warm. This material breaks down slowly, so it can keep the temperature stable for a long time.
- Leaf mold - This compost is unique because of its decomposing leaves. It brings good microbes and worms into your garden, which can help improve the structure and airflow of the soil.
- Pine bark - This mulch makes a nice, thick layer that is great for keeping weeds down in your winter landscape. Depending on your garden needs, you can buy various sizes.
- Grass clippings - Grass is a natural mulching material that you can quickly get from your lawn. After you mow it, please put it in a bag and let it dry before spreading it on your winter beds.
Steps to Winter Mulching
Now that you know all about mulch, it's time for step-by-step instructions on how to use it in your garden. The process only has a few steps. Here's how to do it.
Clear up your garden
Before you put mulch on your flower beds, you need to get rid of old trash and dead plants. After you get rid of the old plants, pull out any weeds. The best thing to do is get rid of weeds in your garden before putting down mulch. If you want to add new mulch to a natural area near your home, remove the old mulch and edge the garden to make a clear line between the grass and the garden bed.
Distribute the Mulch
Now is the time to put new mulch in your garden. We recommend placing the mulch in a wheelbarrow so it is easy to move to different parts of your garden. Then you can shovel the mulch out of the wheelbarrow and into small piles around the beds.
Spread the mulch out evenly across the ground with your hands. Keep adding the material until your garden beds have a 2- to 3-inch layer of mulch.
Your garden is now ready for the winter. The mulch gives your landscape what it needs to survive the winter and grow well in the spring.
Clean Up for Spring
Remember to do the same thing with your garden when you get rid of your winter clothes in the spring. Take away some of the mulch. Add it to your compost pile to keep the cycle going of making healthy organic fertilizer for your plants.
Gutter Cleaning
Rain gutters protect your home's landscaping. They also keep the foundation of your home from getting damaged. But when leaves, sticks, and other things get stuck in gutters, it can cause clogs that let water seep under the roof and into the foundation.
Ice dams are one of the most common dangers of heavy snowstorms. When water builds up behind the ice dam and seeps under the roofing materials, it can cause leaks and other costly damage.
That's why cleaning your gutters and keeping them clean all year is essential.
How to Clean Gutters
- Make sure you have a good, stable ladder that can extend. You can use a ladder stabilizer to keep yourself safe and keep the gutters from getting damaged. Also, it's best to have a helper nearby if you drop something or need help with the ladder.
- Dress for the work. Wear a shirt with long sleeves, work pants, and rubber gloves. It's a dirty job to clean gutters.
- Gather the appropriate tools like spades, shovels, garden hose, leaf blower, lawn mower, tarp, ladder, rake, telescopic gutter cleaner, wheelbarrow, trash cans, trash bags, and a helper for safety.
- Spread a tarp under your workspace to catch all the dirt and protect your lawn and landscaping.
- Once you've cleaned the gutters, you can use a water hose to flush the gutters and downspouts and eliminate any leftover debris.
- Once the gutters are clean, fix any metal that has sagged. Installing a gutter hanger is one way to do this. It's common to do DIY projects for gutter repairs.
- Now that you know the steps to clean your gutter put it on your to-do list at least once a year.
- If winter is coming, you should do what you need to do to get your gutters ready.
