While you may be eager to get your lawn back to its pristine green state, it is important to remember that temperatures of 32 degrees Fahrenheit or lower put your sprinkler system at risk of freezing.

When should I worry about sprinkler system freezing?

When temperatures start to fall, it's time to consider winterizing your sprinkler system. Your lines must be drained or blown out using an air compressor before the first hard freeze. A hard freeze is when then outdoor air dips below 0 degrees Fahrenheit.

How do I keep my sprinkler system from freezing?

Shut off the water supply to the irrigation system. The main shut off valve for your irrigation system needs to be protected against freezing. Make sure it is wrapped with insulation (foam insulation tape and a plastic bag) to protect it from harsh winter temperatures and prevent it from freezing.
