Fall Sprinkler Blowout: Protect Your System from Costly Freeze Damage

26+ Years of Experience Winterizing Colorado Irrigation Systems

Winter is coming and you know your sprinkler system needs winterization, but you're not sure when to schedule it. Wait too long and an early freeze destroys your pipes. Act too early and you'll need to water your lawn manually for weeks. You've heard nightmare stories about burst pipes flooding basements and repair bills exceeding thousands of dollars.

At Sunlight Sprinkler, we take the guesswork out of fall winterization with professional blowout services timed perfectly for Denver's climate. Our certified technicians use proper equipment and techniques to remove all water from your system, protecting it from freeze damage. With over 26 years of Colorado irrigation expertise, we know exactly when and how to winterize for maximum protection.

The Devastating Cost of Skipping Winterization

Water expands when it freezes. That's basic physics, but the damage it causes to irrigation systems is anything but simple. Water trapped in pipes, valves, and backflow preventers expands with incredible force, cracking PVC pipes, shattering brass fittings, and destroying expensive components. A single night below freezing can cause thousands in damage.

The repair bills are staggering.

Burst pipes require excavation to locate and replace. Cracked backflow preventers cost $400-$800 to replace. Damaged valves and manifolds run hundreds more. Freeze damage often affects multiple areas simultaneously, compounding repair costs. Worst of all, you won't discover the damage until spring activation when water gushes from cracks throughout your system. The modest cost of professional winterization seems trivial compared to these repair bills.

What Professional Winterization Includes

Proper sprinkler winterization requires specialized equipment and expertise. Here's what we do during every blowout service:

• Complete System Inspection — Check for existing damage, leaks, or problems that should be addressed before winter
• Controller Programming — Set controller to "rain" or "off" mode to prevent accidental activation during winter
• Water Supply Shutdown — Close and drain the main shut-off valve to prevent water from entering the system
• Zone-by-Zone Blowout — Use high-volume, low-pressure compressed air to evacuate water from each zone individually
• Multiple Air Cycles — Run each zone multiple times to ensure complete water removal from all components
• Backflow Preventer Drainage — Drain and secure backflow preventers, which are particularly vulnerable to freeze damage
• Valve Box Inspection — Check valve boxes for proper drainage to prevent water accumulation and freezing
• Above-Ground Component Protection — Insulate or protect exposed components as needed
• Final System Verification — Confirm all zones are completely evacuated and system is winter-ready
• Spring Service Recommendations — Document any concerns to address during spring activation

Why DIY Blowout Fails

Inadequate Air Compressor Size

Home air compressors lack the volume needed for proper winterization. While they might clear some water, they can't generate the sustained high-volume airflow required to evacuate all moisture. Water remains trapped in low spots, valves, and pipes, waiting to freeze and cause damage.

Dangerous High Pressure

Some homeowners think higher pressure means better results. Wrong. Excessive pressure damages sprinkler heads, cracks pipes, and blows apart fittings. Professional winterization uses high volume at safe pressures (typically 50-80 PSI) to push water out without causing damage.

Incomplete Water Removal

Without proper technique and equipment, water remains in low spots, check valves, and backflow preventers. These trapped pockets freeze and cause the exact damage you're trying to prevent. Professional service ensures complete evacuation.

Damaged Components

Improper blowout technique can crack heads, damage seals, and destroy diaphragms. Repair costs from bad DIY winterization often exceed what professional service would have cost.

Our Proven Winterization Process

Step 1: System Assessment

We inspect your system for existing problems that should be addressed before winter. Finding issues now prevents discovering them as expensive failures next spring.

Step 2: Proper Setup and Connection

We connect professional-grade compressors at the correct location using proper fittings. Our equipment delivers the high volume, controlled pressure needed for effective winterization.

Step 3: Zone-by-Zone Evacuation

Each zone runs separately through multiple air cycles. We monitor air pressure and flow, watching for the spray pattern changes that indicate complete water removal.

Step 4: Critical Component Protection

Special attention goes to backflow preventers, valves, and low spots where water tends to collect. These vulnerable areas receive thorough evacuation and proper drainage.

Step 5: Controller Shutdown

We set your controller to rain mode or off position, preventing accidental activation during winter. Battery backup systems are noted for spring service.

Step 6: Final Verification

We verify complete water removal, document service performed, and provide recommendations for spring activation. You receive peace of mind knowing your system is protected.

When Should You Schedule Fall Blowout?

The Perfect Timing Window

In Denver, we typically winterize systems from mid-October through early November. The goal is timing your blowout after you've finished watering for the season but before the first hard freeze. Scheduling too early means manually watering dry fall weather. Waiting too long risks freeze damage.

Watch Weather Forecasts

The first hard freeze (sustained temperatures below 28°F) triggers mass panic and appointment requests. By then, irrigation companies are overwhelmed and can't accommodate everyone quickly. Proactive scheduling in early October ensures you're protected before that first freeze hits.

Book Early for Best Availability

October and November are our busiest months. Waiting until you see the first frost forecast means competing with hundreds of other homeowners for limited appointment slots. Book in September or early October for your preferred time and guaranteed protection.

Consider Your Landscape's Water Needs

If fall weather stays warm and dry, your landscape may need water into late October. We'll work with you to time winterization appropriately, ensuring your plants get needed moisture before we shut down the system.

What Happens If You Skip Winterization

Cracked Pipes and Fittings

Frozen water expands with tremendous force, cracking PVC pipes and shattering fittings. Underground damage remains hidden until spring, when activation floods your yard and reveals extensive repairs needed throughout your system.

Destroyed Backflow Preventers

These expensive devices ($400-$800 to replace) contain brass and copper components that crack when internal water freezes. Damage often isn't repairable, requiring complete replacement.

Failed Valves and Manifolds

Water trapped in valve diaphragms and manifold chambers freezes and damages these critical components. Valve repair or replacement runs $150-$300 per valve, and systems typically have 4-8 valves.

Damaged Sprinkler Heads

Heads with trapped water crack from freeze expansion. While individual head replacement is relatively cheap ($20-$40), finding and replacing dozens of damaged heads adds up quickly in labor costs.

Controller and Wiring Damage

Moisture intrusion during winter can damage controllers and corrode wiring connections. These electrical issues cause frustrating problems during spring activation.
