5 Signs Your Sprinkler System Needs Winterization—Now

As the seasons shift from the warmth of summer to the crispness of fall, your lawn care checklist changes with it. One of the most critical tasks to complete before the first hard freeze is winterizing your sprinkler system. Waiting too long can lead to frozen pipes, cracked valves, and expensive repairs come springtime. But how do you know when it’s the right time to act?

Your irrigation system often gives clear signals that it’s time for a professional shutdown! Recognizing these 5 signs can save you from significant damage and ensure your system is ready for another successful season. Here are five key indicators that your sprinkler system needs winterization immediately.

The Calendar and the Thermometer Agree

The most reliable sign is the calendar itself. In Nebraska, the first hard freeze typically occurs in October. Don’t wait for the frost to appear on your lawn! Once nighttime temperatures consistently dip into the 40s, the ground begins to cool, and the risk of a sudden, damaging freeze increases. Proactive scheduling is your best defense. It’s wise to have your system winterized before you even have to think about scraping ice off your windshield.

You Spot Small Puddles or Leaks

Take a walk around your yard and inspect your sprinkler heads and valve boxes. Do you see any small puddles of water or persistent damp spots on the ground, even when the system hasn’t run recently? These can indicate slow leaks in the lines or valves. When temperatures plummet, this trapped water will be the first to freeze and expand, turning a minor drip into a major crack. Addressing it now by having a full system blowout from Sprinkler and Irrigation Services is crucial.

The Weather Forecast Predicts a Freeze

Meteorology has become increasingly accurate, so pay close attention to local weather forecasts! When a meteorologist warns of an impending “hard freeze” (when temperatures drop below 28°F for several hours) the clock is ticking. This is a non-negotiable deadline for winterization. Water left in your pipes, backflow preventer, and sprinkler heads will freeze solid, exerting immense pressure that can burst components. We do our best to accommodate last-minute requests, but it’s always better to schedule ahead!

Your Neighbors Are Winterizing Their Systems

Look around your neighborhood. If you see lawn care trucks and hear the distinct sound of air compressors blowing out sprinkler systems, it’s a strong social cue that you should be doing the same. Your neighbors are acting on the same seasonal timeline, so following their lead is a simple way to stay on track and avoid being the last one on the block to protect your irrigation.

You’ve Completed Your Final Mow of the Season

Your lawn’s need for water diminishes significantly as the grass goes dormant for the winter. Once you’ve done your final mow and cleanup for the year, your sprinkler system’s job is officially over until spring. Letting it sit unused but still full of water is a recipe for disaster. Think of that last mow as the final signal! Once the lawnmower is put away, your next call should be to Sprinkler and Irrigation Services’ winterization pros.

Don’t Wait for a Costly Surprise!

Ignoring these signs is a gamble against mother nature that you don’t want to lose! The cost of a professional winterization service is a small fraction of what it would cost to repair a freeze-damaged system. SIS technicians use commercial-grade equipment to ensure that water is forced out of your lines, protecting your entire system throughout the harsh Nebraska winter.
