How to Prepare Irrigation System for Winter: Big Tips & Technology
Winter is a tough season for many outdoor systems, including irrigation systems. If you dont take the right steps to winterize your system, you might end up with frozen pipes, broken valves, and costly repairs in the spring.
In this guide, well cover everything you need to know about how to prepare your irrigation system for winter. Follow these steps to make sure your system stays in top shape when warm weather returns.
Why Winterizing Your Irrigation System is Essential
When temperatures drop below freezing, any water left inside your irrigation pipes can expand and cause cracks or breaks. This can lead to costly repairs and wasted water. Proper winterization will help:
- Prevent pipes from freezing and bursting.
- Save money on repairs.
- Extend the life of your system.
- Ensure a smooth restart in spring.
Step-by-Step Guide on How to Prepare Your Irrigation System for Winter
Step 1: Turn Off the Water Supply
The first thing to do is shut off the water supply to your irrigation system. This prevents additional water from entering the pipes and freezing.
Step 2: Drain All Remaining Water
Even after turning off the water supply, some water may remain inside the pipes, sprinklers, and valves. To remove this, you can use one of three methods:
- Manual Drain Method: Open the drain valves to let the remaining water out.
- Automatic Drain Method: Some systems have automatic drain valves that release water when the pressure drops.
- Blowout Method: Use an air compressor to blow water out of the pipes.
Step 3: Protect Your Backflow Preventer
The backflow preventer is a key part of your irrigation system. To protect it, wrap it with insulation or remove it if possible. If you’re unsure how to do this, learn more about irrigation freeze protection.
Step 4: Remove and Store Hoses and Accessories
Detach any hoses, sprinkler heads, or other accessories and store them in a dry place for the winter.
Step 5: Check for Leaks and Repairs
Before winter arrives, check for any leaks or damages. If you find a PVC pipe issue, heres how to fix a PVC leak.

Common Mistakes to Avoid
