However, most sprinkler contractors recommend homeowners in freezing climates have their systems blown out for the best protection.<\/p>    <p class=\"wp-block-paragraph\"><strong>Caveat:<\/strong> Every system is slightly different, but the basic winterizing principles are the same. You want to shut off the water to the irrigation system, expel water from the pipes and <a href=\"https:\/\/lawnlove.com\/blog\/types-of-sprinkler-heads\/\">sprinkler heads<\/a>, and drain water from the backflow preventer. Then, shut down the controller for the winter.<\/p>    <h3 id=\"1-shut-off-the-water\" class=\"wp-block-heading\"><span id=\"shut-off-the-water\">Shut off the water<\/span><\/h3>    <figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/lawnlove.com\/blog\/wp-content\/uploads\/2024\/08\/Water-Valves.jpeg\" alt=\"a person shutting off water valves\"\/><figcaption class=\"wp-element-caption\">The first step in winterizing your sprinkler system is cutting off the water supply at the main shutoff valve.

Sometimes the shutoff is in the basement, a crawl space, or a valve box close to the water meter or main water line.<\/p>    <p class=\"wp-block-paragraph\">For systems with backflow preventers, you need to shut them off, too. In most cases, two valves feed into the backflow device, and both need to be shut off.<\/p>    <h3 id=\"2-turn-off-the-watering-programs\" class=\"wp-block-heading\"><span id=\"turn-off-the-watering-programs\">Turn off the watering programs<\/span><\/h3>    <p class=\"wp-block-paragraph\">After shutting off the water, turn off all scheduled programs on the controller, but don&#8217;t shut it off completely.

The exact timing depends on your local climate. Keep sprinklers running until your grass stops growing, then winterize before your area starts getting consistent hard freezes at night or consecutive days with below-freezing temperatures.<\/p>    <p class=\"wp-block-paragraph\">Most systems are winterized in early to mid-fall, ahead of the first hard freeze, in line with expert <a rel=\"noreferrer noopener\" href=\"https:\/\/www.landscapemanagement.net\/how-and-when-to-winterize-your-irrigation-system\/\">winterization timing<\/a> guidance.<\/p>    <p class=\"wp-block-paragraph\"><strong>Some things to consider with timing:<\/strong><\/p>    <ul class=\"wp-block-list\"> <li><p>Colder climates see seasonal frosts earlier, so systems should be winterized sooner than in more temperate zones.<\/p><\/li>    <li><p>Systems with above-ground components should be winterized earlier to avoid damage to exposed pipes or a backflow preventer.<\/p><\/li>    <li><p>Systems with only underground components can wait longer because the soil helps insulate everything.<\/p><\/li> <\/ul>    <h2 id=\"10-what-happens-if-you-dont-winterize-your-sprinkler-system\" class=\"wp-block-heading\"><span id=\"what-happens-if-you-dont-winterize-your-sprinkler-system\">What happens if you don&#8217;t winterize your sprinkler system<\/span><\/h2>    <p class=\"wp-block-paragraph\">If you don&#8217;t winterize your system, any water left in the lines, valves, or heads can freeze and expand. Like a can of soda left in the freezer, that expanding ice can cause components to crack, bend, or burst.<\/p>    <p class=\"wp-block-paragraph\">Freeze damage can lead to costly repairs, especially if your backflow preventer is damaged. Frozen water in sprinkler heads can expand and harm the internal pieces, rendering the heads useless or ineffective.<\/p>    <p class=\"wp-block-paragraph\">Mike Marlow, co-founder and owner at Heroes Lawn Care in Omaha, Nebraska, puts it simply: &#8220;Water freezes, it expands, and that can crack your pipes.&#8221;<\/p>    <p class=\"wp-block-paragraph\">What if an early freeze hits before you&#8217;ve winterized? You don&#8217;t have to panic. The season&#8217;s first freeze usually isn&#8217;t enough to damage underground components because the soil acts as an insulator until the ground freezes.<\/p>    <p class=\"wp-block-paragraph\">An early freeze can still damage exposed pipes or backflow devices, so cover above-ground components with blankets or old towels until you can winterize the system.<\/p>    <h2 id=\"11-how-much-does-sprinkler-winterization-cost\" class=\"wp-block-heading\"><span id=\"how-much-does-sprinkler-winterization-cost\">How much does sprinkler winterization cost<\/span><\/h2>    <p class=\"wp-block-paragraph\">A professional <a href=\"https:\/\/lawnlove.com\/blog\/winterize-sprinkler-system-cost\/\">sprinkler winterization costs<\/a> $60 to $145, with an average winterization cost of about $85 for most homes. Your price depends on the number of zones and the draining method you choose.<\/p>    <p class=\"wp-block-paragraph\">Doing it yourself costs little beyond insulation supplies, usually under $25, if you already own an adequately sized air compressor.<\/p>    <h2 id=\"12-faqs\" class=\"wp-block-heading\"><span id=\"faqs\">FAQs<\/span><\/h2>    <div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1789669759162886\"><strong class=\"schema-faq-question\">How do I turn my sprinkler system back on in spring?<\/strong> <p class=\"schema-faq-answer\">Reopen the backflow valves and main shutoff slowly to avoid a pressure surge, then restore power and reprogram the controller if needed.

The exact timing depends on your local climate. Keep sprinklers running until your grass stops growing, then winterize before your area starts getting consistent hard freezes at night or consecutive days with below-freezing temperatures.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Most systems are winterized in early to mid-fall, ahead of the first hard freeze, in line with expert <a rel=\"noreferrer noopener\" href=\"https:\/\/www.landscapemanagement.net\/how-and-when-to-winterize-your-irrigation-system\/\">winterization timing<\/a> guidance.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p><strong>Some things to consider with timing:<\/strong><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:list -->\n<ul class=\"wp-block-list\"><!-- wp:list-item -->\n<li><p>Colder climates see seasonal frosts earlier, so systems should be winterized sooner than in more temperate zones.<\/p><\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><p>Systems with above-ground components should be winterized earlier to avoid damage to exposed pipes or a backflow preventer.<\/p><\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><p>Systems with only underground components can wait longer because the soil helps insulate everything.<\/p><\/li>\n<!-- \/wp:list-item --><\/ul>\n<!-- \/wp:list -->\n\n<!-- wp:heading {\"anchor\":\"10-what-happens-if-you-dont-winterize-your-sprinkler-system\"} -->\n<h2 id=\"10-what-happens-if-you-dont-winterize-your-sprinkler-system\" class=\"wp-block-heading\">What happens if you don't winterize your sprinkler system<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>If you don't winterize your system, any water left in the lines, valves, or heads can freeze and expand. Like a can of soda left in the freezer, that expanding ice can cause components to crack, bend, or burst.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Freeze damage can lead to costly repairs, especially if your backflow preventer is damaged. Frozen water in sprinkler heads can expand and harm the internal pieces, rendering the heads useless or ineffective.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>Mike Marlow, co-founder and owner at Heroes Lawn Care in Omaha, Nebraska, puts it simply: \"Water freezes, it expands, and that can crack your pipes.\"<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>What if an early freeze hits before you've winterized? You don't have to panic. The season's first freeze usually isn't enough to damage underground components because the soil acts as an insulator until the ground freezes.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph -->\n<p>An early freeze can still damage exposed pipes or backflow devices, so cover above-ground components with blankets or old towels until you can winterize the system.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading {\"anchor\":\"11-how-much-does-sprinkler-winterization-cost\"} -->\n<h2 id=\"11-how-much-does-sprinkler-winterization-cost\" class=\"wp-block-heading\">How much does sprinkler winterization cost<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph -->\n<p>A professional <a href=\"https:\/\/lawnlove.com\/blog\/winterize-sprinkler-system-cost\/\">sprinkler winterization costs<\/a> $60 to $145, with an average winterization cost of about $85 for most homes.
