Winterize Sprinklers Long Island – Protect Your System Before the Freeze

As temperatures drop on Long Island, one thing is certain: if your irrigation system isn’t properly shut down before the first hard freeze, you’re likely to face repairs come spring. Water left inside pipes can expand, crack fittings, burst underground lines, or damage valves and backflow preventers.

That’s why smart homeowners and property managers turn to RN Lawns for professional sprinkler winterization services every fall.

🧊 Why Winterizing Your Sprinklers Is So Important

Your sprinkler system is an investment. Like any outdoor system in New York’s climate, it needs seasonal care. Winterization isn’t just a nice-to-have—it’s a must.

Here’s what happens if you skip it:

• Pipes and fittings freeze, expand, and break underground
• Cracked sprinkler heads and valves lead to leaks in spring
• Backflow preventers can fail and become costly to replace
• Startup in spring becomes dangerous or unpredictable

RN Lawns helps you avoid all of that with a reliable, thorough winter shutdown.

✅ What’s Included in a Sprinkler Winterization Service?

Our winterization process is designed to completely remove water from your irrigation system and prevent freeze damage:

• System shut-off at the main valve
• Air compressor blowout of all zones and lateral lines
• Inspection of sprinkler heads for leaks or damage
• Draining of backflow preventers and filters
• Controller shutdown or adjustment to winter mode

We use commercial-grade equipment to ensure every drop of water is pushed out of your system safely.
