Why Winterizing Your Sprinkler System Is Important
Winterizing your sprinkler system is crucial to prevent costly damage during the cold season.
Here’s why it’s necessary:
- Prevents Freezing Damage: Any water left in the pipes can freeze and expand, potentially causing cracks, burst lines, or damaged valves. Turning off the water supply at the isolation valve is crucial to ensure proper draining and prevent freezing damage.
- Protects Sprinkler Components: Frozen water in the system can lead to broken sprinkler heads and cracked fittings, resulting in expensive spring repairs.
- Avoids Pressure Issues: Freezing can cause low pressure in your system, reducing performance when you restart it.
- Saves Money on Repairs: A properly winterized system avoids costly fixes in the spring, preserving the health of your irrigation system.
By taking the time to remove all the water from your sprinkler system and protecting vulnerable parts from freezing, you’ll ensure your system is ready to go when the warmer months return.
How to Winterize Your Sprinkler System: Step-by-Step Process
Winterizing your sprinkler system correctly is crucial to avoid damage during the cold months.
Follow these steps to ensure your irrigation system is fully prepared for winter.
Tools and Materials Needed
Before starting, gather these essential items to make the winterizing process smoother:
- Air compressor(40-80 PSI, 30-50 CFM)
- Coupler or quick-connect adapter
- Safety goggles
- Wrench or screwdriver
- Insulation tape or foam covers
1. Turn Off the Water Supply
Locate and close the main shut-off valve to prevent more water from entering the system.
Locate the main valve near the water meter to turn off the water supply to the system, ensuring it is properly drained and protected from freezing temperatures.
Make sure your backflow preventer is shut off as well to avoid potential freezing.
2. Turn Off the Timer or Set It to Rain Mode
Switch your sprinkler system’s automatic timer off or set it to rain mode.
This keeps your programming intact while preventing accidental system activation during the winter.
3. Drain the System
To avoid water freezing in your pipes and valves, you need to drain the system.
There are three main methods.
Please note that the “blow-out method” is the best way to ensure that all water is removed from your system.
However, we also recommend you hire a professional irrigation professional to do this method since it can damage parts of your irrigation system if not implemented correctly.
3.1 Manual Draining
Open the valves at the lowest points of the system to let the water out.
- Once all the water is drained, close the valves to avoid air getting trapped in the system. Follow the link to understand how valves work in irrigation systems.
3.2 Automatic Draining
Some sprinkler systems are equipped with automatic drain outlets that release water when the pressure drops.
- Double-check each zone to ensure that all the water has been properly drained.
3.3 Blow-Out Method
Blowing out sprinklers before winter uses compressed air to force any remaining water out of the system.
- Attach the air compressor to the system with a quick-connect adapter.
- Set the pressure to 40-50 PSI for polyethylene pipes or 80 PSI for PVC pipes.
- Start with the zone farthest from the compressor, then move through each zone until all the water has been cleared.
Pro Tip: Stop blowing air as soon as water stops flowing from the sprinklers to avoid damaging the components.
4. Insulate Exposed Components
Wrap any exposed pipes, valves, or backflow preventers with insulation tape or foam covers to protect them from freezing.
Be sure to leave air vents and drain outlets unblocked.
By following these steps, you’ll ensure your sprinkler system is properly winterized and ready to withstand the Toledo winter.
Common Winterization Mistakes to Avoid
Even when you know how to winterize your sprinkler system, mistakes can happen that lead to costly repairs in the spring.
Here are some common missteps to avoid.
Using Too Much Air Pressure
When using compressed air to blow out your irrigation system, too much pressure can damage pipes and sprinklers.
- Tip: Keep your air compressor set to 40-50 PSI for poly pipes and no more than 80 PSI for PVC pipes. Higher pressure can crack components, leaving you with costly repairs.
Forgetting to Drain the Backflow Preventer
If you leave water trapped in the backflow preventer, it can freeze and crack, resulting in expensive damage.
- Tip: Always fully drain the backflow preventer by opening the ball valve. This ensures no water is left behind to freeze over the winter.
Overheating Sprinkler Components
Running compressed air too long after the water stops flowing can overheat plastic parts in your sprinkler heads, causing damage.
- Tip: Once water has been cleared from a zone, stop the airflow to avoid overheating the sprinklers.
By avoiding these common errors, you’ll ensure your irrigation system stays in great shape through the cold months, saving you time and money when it’s time to start up in the spring.
Cost Comparison: DIY vs. Hiring a Professional
Winterizing your sprinkler system can be done on your own or with professional help.
Understanding the costs and risks of each option will help you make the best decision for your irrigation system.
DIY Winterization
If you choose to handle the winterization yourself, the main cost is renting or using your own air compressor and basic equipment.
- Cost: Minimal, as you’re mainly covering the expense of an air compressor and a few materials like insulation tape.
- Hidden Costs: If the system isn’t properly winterized, water trapped in the pipes can lead to freeze damage, causing cracked lines, valves, and backflow preventers, which may require costly repairs.
- Risk: High, especially if you’re unfamiliar with your sprinkler system’s layout or the correct air pressure needed to properly clear the water from the system. This can increase the likelihood of making mistakes that can hurt your system in the long run.
Professional Winterization
Hiring a professional guarantees that your irrigation system will be properly winterized, protecting it from damage when temperatures drop.
- Cost: Professional services typically cost around $249, depending on the size and complexity of your system.
- Hidden Costs: None. The job is done by experts who know exactly how to drain your system and protect it from freezing, ensuring no water is left behind.
- Peace of Mind: Professionals ensure the job is done correctly, reducing the risk of freeze-related damage to your pipes, valves, and sprinklers. This can be particularly valuable if your system is complex, has multiple zones, or if you’re dealing with more sensitive components like backflow preventers.
Choosing between DIY and professional winterization depends on your confidence in handling the task and the complexity of your irrigation system.
For a small upfront cost, a professional ensures your system is fully protected, avoiding costly spring repairs.
Pro Tips for a Successful Winterization
To ensure your sprinkler system is fully prepared for winter, follow these expert tips.
These steps will help you avoid common issues and keep your irrigation system in great shape during the cold months.
Timing is Key
Start winterizing your system before the first hard freeze.
In Toledo and Northwest Ohio, this usually means late fall.
- Tip: Don’t wait until temperatures drop drastically—preparing your lines early can prevent freeze damage and protect your pipes and valves from cracking.
Don’t Skip Insulation
After draining the system, make sure to insulate any exposed valves, backflow preventers, and water supply lines.
- Tip: Wrap them in insulation tape or foam covers, but make sure not to block any airflow from air vents or drain outlets.
Double Check Everything
Before considering the job done, make sure to double-check that all valves are closed and the main shut-off valve is tightly sealed.
- Tip: Verify that every zone has been drained and no water is left trapped in the system, especially at the lowest point of the lines or near the main valve.
