Why Winterizing Is Essential

Don't Let Long Island Winters Crack Your Irrigation System

When Long Island temperatures drop below freezing, water left inside your pipes, valves, and backflow preventers expands. This leads to cracked manifolds, burst lines, and thousands of dollars in spring repairs.

  • Prevent Frozen & Burst Pipes: We use commercial-grade high-volume air compressors to ensure 100% of residual water is removed.
  • Stay NYS Compliant: Combined backflow testing ensures your water supply is safe and meets local water district regulations.
  • Hassle-Free Spring Start-Up: Preparing your lawn system correctly now guarantees a seamless spring activation.

Sprinkler Winterization FAQs

When should I winterize my sprinkler system on Long Island?

What does the Rate-Lock Guarantee mean?

  • Answer: When you service your system with us this fall, you get priority scheduling and guaranteed lowest rates on your spring start-up and seasonal maintenance for next year.
