Irrigation winterization FAQs

When to winterize a sprinkler system

Winterizing a sprinkler system between August and November before the first big freeze of the year is the best way to avoid damage.

When to open and de-winterize a sprinkler system

Opening and de-winterizing a sprinkler system is weather-dependent. The first irrigating of the year should start after all risk of frost has passed in the spring. Water freezing inside the lines from de-winterizing too early causes many damages.

How do I winterize a sprinkler system myself?

Winterizing a sprinkler system yourself requires an air compressor, air hose, blowout fitting or adapter, safety glasses, and a water shut-off key.

Steps to winterizing a sprinkler system yourself include:

  1. Shut off water supply to the system.

  2. Drain the backflow valve / backflow preventer (if there is one). Then close it.

  3. Connect the air compressor hose to the irrigation system.

  4. Blow the compressed air through each zone to remove water from each line.

  5. Seal all open water lines to prevent debris from getting inside.

  6. Shut off the sprinkler controller.

What happens if I don't winterize my sprinkler system?

If you don’t winterize your sprinkler system, water might freeze, expand, and break the system components. Replacing a sprinkler system costs $1,800 to $5,200 on average, plus $50 to $100 per hour for removing the old system first.
