Sprinkler Winterization – Why it Matters for Your Lawn

Oct 5, 2023 | Plumbing

Winter is coming, and along with it comes the task of preparing your lawn for the cold season. One essential task to carry out before winter hits is sprinkler winterization. This process involves draining all the water from your sprinkler system to avoid damage to the pipes and other components during the cold months. Sprinkler winterization plays an essential role in keeping your lawn healthy, green, and beautiful. In this blog post, we’ll delve into why sprinkler winterization matters for your lawn and how to go about it.

Protect Your Sprinkler System from Freezing Temperatures

When the temperature drops below freezing, any water left in your sprinkler system can freeze and expand, leading to damage to the pipes drain valves, fittings, valves, and other components. A frozen sprinkler system can result in cracks, leaks, and broken parts that can be expensive and time-consuming to repair. Sprinkler winterization is the process of removing all water from your sprinkler pipes and components, ensuring that no water is left to freeze and cause damage.

Preserve Your Lawn’s Health and Appearance

Winterization is essential to ensure that your lawn remains healthy and beautiful throughout the cold season. If you don’t winterize your sprinkler, the lines can freeze and make it impossible for the necessary moisture to be delivered to your lawn. Some sprinklers have rain mode which can be very helpful. When your yard is deprived of a water supply, it can dry up, turn brown, and even die. This can lead to expensive repairs, including re-sodding or reseeding large sections of your lawn after the cold is over. To avoid these complications, it is necessary to carry out sprinkler winterization.

Extend the Life of Your Sprinkler System

Protecting your sprinkler system should be a top priority as it enables you to keep your lawn healthy and green. Winterizing your sprinkler components will ensure that they are free of frost and keep your sprinklers in good condition. As a result, your sprinkler system will be in good condition, and you’ll extend its life span, saving you substantial amounts of money in repairs or replacement costs.

Avoid Costly Repairs

The cost of replacing broken sprinkler lines and other sprinkler station components that have been damaged by freezing temps can be staggering. The most common repairs, such as replacing broken pipes and heads, can rack up quite a bill. The good news is that this expense is avoidable by winterizing your sprinkler system. In the long run, it is more cost-effective to winterize your sprinklers than replacing parts due to damages that could have been avoided.

Why You Should Use a Professional for Sprinkler Winterization


Winter is coming, and it’s important to prepare your sprinkler system for the colder weather. Sprinkler winterization is a crucial step in maintaining your system and preventing costly damage. While it may seem easy enough to do on your own, it’s always best to leave it to the professionals. Next, we’ll discuss why you should use a professional for sprinkler winterization.

Proper Drainage

Sprinkler winterization requires proper drainage of the entire system. If there is any remaining water left in the pipes, it can freeze and cause them to burst into the backflow device or backflow isolation valves leading to expensive repairs. Professionals have the knowledge and equipment necessary to ensure all water is successfully drained from the system and the air vents are not blocked.

Inspecting for Damage

During the winterization process, a professional will inspect the entire sprinkler system for any damage or wear and tear. They can identify any issues early on and make necessary repairs. Catching small problems before they turn into bigger ones can save you a lot of money in the long run.

Time and Convenience

Winterizing your sprinkler system yourself can be time-consuming and, in some cases, frustrating. A professional knows exactly what to do, and can complete the job much faster. Using a professional also ensures that the job is done right the first time, reducing the need for repeat visits.

Specialized Tools and Equipment

Professionals come equipped with specialized tools and equipment specifically for sprinkler winterization. They have the tools needed to blow out the entire system, get into hard-to-reach areas, and more. Investing in these tools for one-time use does not make sense, especially when it can be done easily and efficiently by a professional.

Warranty Protection

If you have a warranty on your sprinkler system, it may require professional winterization to stay valid. Neglecting this step could void your warranty, leaving you with costly repairs. Using a professional ensures that your warranty stays intact, keeping your system protected and saving you money in the long run.

As you can see, there are many reasons why you should use a professional for sprinkler winterization. From proper drainage to specialized tools and equipment, professionals have the knowledge and expertise to keep your system running smoothly all year round. Schedule your sprinkler winterization with a professional today and enjoy peace of mind knowing that your system is in good hands.

What Happens If You Don’t Do Sprinkler Winterization?

Winter is a season of snow, celebration, and beautiful foliage. However, it also brings some challenges, particularly when it comes to preserving your lawn and garden’s irrigation system. Before winter sets in, it is essential to prepare your sprinkler system to avoid any damage from frost, snow, and icy conditions. Sprinkler winterization is a critical component of the maintenance schedule. But what happens if you don’t do sprinkler winterization? Below, we provide you with the answers.

Freezing and Thawing

If you don’t drain the water in your irrigation system before winter sets in, the water in the pipes will freeze during the cold season. This can be done using a manual drain valve or other methods for draining. Since water expands as it freezes, the expanding water can cause the pipes to burst, leading to considerable damage and expenses. When this happens, you’ll need to replace the entire infrastructure that is affected. Replacing the pipes can be quite expensive and may cause further disruptions to the lawn or garden’s infrastructure.

Broken Sprinkler Heads

Sprinkler winterization also involves the removal of water from the sprinkler heads and pipes. When moisture freezes, it can cause the sprinkler heads to crack or break, particularly if the water pressure is high. The freeze-thaw cycle can cause water to seep into the sprinkler head before freezing, thus causing it to expand and damage the head. Alternatively, when the water freezes, it can also cause the entire mechanism to become misaligned, leading to water wastage.

Overworking the Pump

If you don’t do sprinkler winterization, the water left in the pipes can cause the pump to overwork itself trying to push water through the frozen pipes. The extra air pressure also can cause the pump to overheat and lead to motor burnout. If the pump burns out, it will need repair or replacement that can cost you unnecessary expenses.

Decrease in Efficiency

The damage that results from not winterizing your sprinkler system can cause inefficiencies that can result in increased water usage. For example, if the sprinkler head freezes, it may lead to the system overwatering the yard by covering an area twice or three times, resulting in excess water usage. The same may happen when the sprinkler head’s flow is impeded due to damage, leading to even more overwatering. The result is an increased water bill.

Safety Risks

Lastly, not doing sprinkler winterization can pose serious safety risks. Water that freezes under the ground or in pipes can release hazardous gases that can affect your health. The water can also cause slips and falls on slippery surfaces, making the lawn hazardous to walk on.


Sprinkler winterization is necessary to prevent damage and unnecessary expenses. Failing to winterize your sprinkler system can lead to damages such as broken sprinkler heads, burst pipes, overworked pumps, decreased efficiency, and even safety hazards. This winter, be sure to consider the importance of sprinkler winterization to protect your irrigation system and investment. Contact an expert for professional sprinkler winterization services to save you money and time and prevent disastrous consequences.

When to Winterize Your Sprinkler System


As the seasons change from fall to winter, it is important to start preparing your home and garden for the harsh winter weather. One thing that many homeowners may forget is the importance of winterizing their sprinkler systems. With freezing temperatures and snowfall on the horizon, it is essential to ensure that your sprinkler system is protected to avoid costly damages come springtime. Keep reading to find out when is the optimal time to winterize your sprinkler system.

Winterizing your sprinkler system involves removing all water from the pipes and components of the system by blowing compressed air through the lines. Ideally, you want to have your sprinkler system winterized before the first hard freeze of the season. In most cases, this occurs between mid to late October and early November, depending on your region’s climate.

If you live in an area with mild winters, you can wait until November or even the first week of December to winterize your lawn sprinkler system again. However, if you live in an area with harsher winters, it is essential to winterize your sprinkler system earlier to avoid frozen or burst pipes, or no water supply which can be costly to repair.

Another factor to consider is your sprinkler system’s location. If you live in an area with high altitude, you will need to winterize your system earlier than those living at lower elevations. This is because colder air is denser and heavier, and it settles in low areas, meaning pipes and components at lower elevations are more prone to freeze and damage.

Winterizing your sprinkler system is a critical task that shouldn’t be overlooked if you want to maintain the health, beauty, and lifespan of your lawn. It protects your sprinkler system from freezing temperatures, preserves your lawn’s beauty, extends the life of your sprinkler system, and protects you from costly repairs. By following the steps provided in this article, you can easily winterize your sprinkler system, saving you money and time.
