Learn how to winterize your irrigation system ll The Home Depot Garden Club



One of the last tasks you need to do before winter is to prepare your garden irrigation system for cold weather. Depending on the size of your yard, it won’t take too much time and the effort protects your investment down the road.
Most steps are easy enough to do yourself, but when in doubt, contact a licensed irrigation company to winterize your system. Whichever way you choose, it is time and money well spent.

Winterize Your Irrigation System:

  1. Shut off main water supply to all irrigation systems and outdoor faucets.
  2. Turn off controller or timer on automatic systems.
  3. Disconnect soaker hoses from the water source and remove end caps. Drain water completely. You can remove and store the hoses for the winter, which prolongs their lives, but it’s not necessary.
  4. Drain pipes to avoid breakage from freezing water. Use a manual drain valve, automatic drain valve or a compressed air blow-out method. An air compressor comes with safety risks, so we recommend contacting an irrigation specialist if you choose this method.
  5. Wrap the main shut-off valve, above-ground pipes, valves and backflow preventers with foam insulation tape and plastic bags.


If you have questions about your system, don’t take chances. Contact the company that installed it, the manufacturer or a licensed irrigation company for assistance.
