It may seem a little early to talk about sprinkler winterization with the warm fall we’ve had in Wichita, but Kansas weather can flip fast. That’s exactly why it’s so important to prep your sprinkler systems early. Any water left sitting in an irrigation system when the freeze hits has nowhere to go except to expand… and when that water expands, it can split pipes, damage valves, backflow preventers, and break sprinkler heads.
Winterizing your irrigation system before the winter weather hits prevents all these problems. Scheduling a simple service, like a sprinkler blowout, clears the water out of your system before the cold gets to it. We’ve put together some helpful tips and things to keep in mind when scheduling your winterization service.
One of the most important benefits of winterization is that it extends the lifespan of your entire sprinkler system. It also helps prep your system for spring, so you’re not surprised by leaks or water pressure issues. Some additional benefits of winterization include:
The real payoff comes in the springtime. A properly winterized sprinkler system starts up nice and easy, with no surprises or problems to fix. Winterization is a small, well-timed step that keeps your irrigation system and property safe for years.
Timing is the most important factor to remember when winterizing your sprinklers. Most homeowners either wait too long or miss the winterization window altogether. The goal is to have the system cleared before the first hard freeze, which we define as 28°F or below for at least an hour. In Wichita, that can usually hit as early as mid-to-late fall, around late October to mid-November.
The safest move is to schedule service about a week before the first expected hard freeze. Fall weather here turns quickly, so it's best to schedule an appointment before the cold hits. Remember, earlier is always safer than later: You can never be too early but you will definitely regret being too late.
Winterization is more involved than most homeowners may think. It is not just unscrewing your hose and stowing it away until next summer! With different methods to choose from, it can be difficult to know which one is right for your system. In general, the right method depends on how your specific system was built.
These are designed to release water on their own when pressure drops, but they rarely empty completely. A professional inspection can confirm if the system is actually clear rather than assuming it drained as intended.
In manual drain systems, valves are opened deliberately, and a technician checks the system's low-lying areas where water collects and hides. Missing one trapped pocket of water can cause serious issues throughout the winter.
This is by far the most thorough approach, requiring a trained professional to perform. It uses pressurized air to ensure that every bit of water has been forced out of the lines. This requires using the correct PSI for your irrigation pipes and materials, while protecting the backflow preventer. Too much pressure or the wrong technique can permanently damage the entire system. This is where professional equipment and judgment matter the most– and why a blow-out is not a DIY project we would recommend.
The biggest risk with irrigation winterization isn't that it is overly complicated, it’s that mistakes are invisible until spring, when they will be more expensive to fix. A system that was "mostly" drained is not winterized. A blow-out run at the wrong pressure can crack a line just like a freeze would. Knowing how the system works makes a huge difference when spring rolls around and could even save you hundreds in sprinkler repairs.
Winterization is one half of the cycle. Turning the system back on in spring comes with its own challenges and requirements. A properly winterized system is also much easier and cheaper to start up because there is no freeze damage to find and fix. At Four Star Lawn Care, we address both ends of the cycle and know the local requirements. So when spring hits, you can relax knowing your property is in good hands.
The window to winterize your sprinkler system is short, and it closes with the first hard freeze. If your irrigation system hasn't been cleared for the season, now is the time, before the weather decides for you.
