IRRIGATION BLOWOUT SERVICES

Irrigation Blowout Services in Knoxville, Tennessee:

Essential Maintenance for Your Irrigation SystemAs a homeowner or business owner in Knoxville, Tennessee, maintaining a beautiful landscape is a year-round commitment. With the region's hot, humid summers and the potential for cold, unpredictable winters, it's essential to ensure your irrigation system is in top shape, especially as the seasons change.

One of the most important tasks you can perform to protect your irrigation system is scheduling an irrigation blowout service before the first freeze.

Irrigation blowouts are a critical part of proper seasonal maintenance for sprinkler systems in Knoxville, where freezing temperatures, especially in late fall and winter, can cause severe damage if left unaddressed.

​This service helps prevent costly repairs, extend the lifespan of your system, and ensure your irrigation is ready to go when the warmer months arrive. Below, we’ll dive into what irrigation blowout services are, why they are particularly important for residents of Knoxville, and how they can benefit your irrigation system and property.

What Is an Irrigation Blowout?An irrigation blowout is the process of using compressed air to force the remaining water out of the pipes, valves, and sprinkler heads of your irrigation system. In a region like Knoxville, where winter temperatures can dip below freezing, any residual water left in the pipes can freeze, expand, and cause serious damage to the system. By performing a blowout, you ensure that the pipes are clear of water and that your irrigation system won’t be vulnerable to freezing and bursting during the colder months.

Why Is an Irrigation Blowout Important for Knoxville Homeowners?In Knoxville, the winter weather can be unpredictable. Although average temperatures typically don’t drop as low as other regions of the country, freezing temperatures are not uncommon, particularly in late fall and early winter. Even a few nights of freezing temperatures can cause significant damage to an irrigation system that isn’t properly winterized.
Here are some reasons why Knoxville residents should prioritize an irrigation blowout:
​

1. Prevent Pipe Damage from Freezing: As winter temperatures approach, it's critical to protect your irrigation system from the risk of freezing. If water is left inside the pipes, sprinkler heads, or valves, it can freeze and cause the pipes to crack or burst. A blowout removes all the water from the system, eliminating the risk of freeze-related damage, which could cost thousands in repairs.
2. Knoxville's Cold Winter Nights: While Knoxville generally enjoys mild winters, temperatures often drop below freezing on certain nights in November, December, and January. This makes irrigation blowouts especially necessary in the fall to ensure your system is protected before the freeze hits.
3. Extending the Life of Your Irrigation System: A well-maintained irrigation system will last much longer than one that’s neglected. By scheduling an irrigation blowout each fall, you’re investing in the longevity of your system. This simple task can prevent expensive repairs or replacements due to freeze damage.
4. Prevent Costly Spring Repairs: If your irrigation system isn’t properly winterized, you may find yourself with cracked pipes, damaged sprinkler heads, and non-functioning valves when you try to turn it back on in the spring. These repairs can be costly and time-consuming. Scheduling a blowout service before the winter freeze helps avoid these expensive surprises.
5. Ensuring Efficient Irrigation in the Spring: Once the warmer weather rolls around and it’s time to turn your irrigation system back on, you want to make sure it’s working properly. A blowout ensures that no water has been left in the system, so there will be no lingering issues, and your system will be ready to provide efficient irrigation as soon as the growing season begins.
6. Protecting Your Investment: In Knoxville, where landscaping can be a significant investment, you want to ensure that your irrigation system is working at full capacity. Preventing water wastage and ensuring even coverage can help conserve water and keep your landscape healthy. A properly winterized system will be more efficient in the spring, promoting lush, vibrant lawns and gardens.

How Does an Irrigation Blowout Work?The blowout process involves using compressed air to clear out any remaining water from the pipes, sprinkler heads, and valves in your irrigation system. This is how the process typically works:
1. Shut Off the Water SupplyThe first step is to shut off the main water supply to your irrigation system. This step ensures that no more water enters the system while the blowout is happening.
2. Drain the SystemNext, the system is manually drained as much as possible by opening drain valves to let any excess water flow out. While this helps clear out some water, it does not remove all of it, which is why a blowout is necessary.
3. Connect Compressed AirA high-powered air compressor is connected to the irrigation system at the mainline or backflow preventer. The air is then blown through the system to push any remaining water out of the pipes, sprinkler heads, and valves.
4. Blow Out the LinesThe technician uses the air compressor to blow air through the pipes and sprinkler lines, expelling water from all components. The technician will carefully monitor the air pressure to ensure it is appropriate, as excessive air pressure could damage the system. This step is done zone by zone to ensure thorough removal of water from all parts of the system.
5. Check for Proper DrainageDuring the blowout process, the technician checks the sprinkler heads and valves in each zone to confirm that water is being properly cleared from the system. The system is purged until there’s no more visible water coming out.
6. Close Valves and Finish the ProcessAfter all zones have been purged, the technician will close the valves and disconnect the air compressor. At this point, your irrigation system should be completely drained and ready for the winter months.
7. Final InspectionSome companies will also inspect the system to check for any potential leaks, cracks, or other issues that could cause problems in the future. They may make recommendations for repairs or other maintenance needs to keep your system running efficiently.
When Should Knoxville Homeowners Schedule an Irrigation Blowout?In Knoxville, the ideal time for an irrigation blowout is typically late October to early November. The first frost can happen as early as late October, so scheduling the blowout service before this point is important to prevent any water from freezing inside your irrigation pipes. The key is to have your irrigation system winterized before the temperatures dip below freezing.
If you wait too long and experience an early freeze, you risk leaving water in the system, which could freeze and cause costly damage. Scheduling your blowout service earlier in the fall helps avoid this risk.
Why Hire a Professional for Irrigation Blowout Services in Knoxville?While it may be tempting to attempt a DIY irrigation blowout, it’s always best to hire a professional for the job. Here’s why:

1. Expertise with Local Conditions: A professional irrigation technician in Knoxville will understand the local climate and freezing patterns. They know exactly when the first freeze is likely to occur and will time the blowout accordingly. They also understand the nuances of local irrigation systems and are familiar with the specific needs of Knoxville properties.
2. Proper Equipment: Blowouts require the use of a high-powered air compressor, which is not typically available to homeowners. A professional technician will have the right equipment to do the job safely and efficiently without causing damage to your system.
3. Thoroughness and Safety: Properly performing an irrigation blowout requires careful attention to detail. Using too much air pressure, not fully clearing the system, or failing to check each zone can lead to incomplete winterization or even damage. Professionals ensure that the job is done thoroughly, with all air pressure carefully regulated to avoid harm to your system.
4. Time Savings: Blowouts can take time, especially with larger systems. Hiring a professional allows you to save time and focus on other important fall tasks, knowing that your irrigation system is being properly cared for.
5. Comprehensive Service: In addition to blowing out the system, professionals can also inspect your irrigation system for any potential issues, perform minor repairs, and make recommendations for the coming season. They can also ensure that your backflow preventer is properly winterized, which is important for protecting the health of your water supply.
