How do I stop my sprinkler pipes from freezing?
To keep the water inside the pipes of a wet fire sprinkler system from freezing in areas where the temperature may drop below 50 degrees, an antifreeze loop is added. By adding antifreeze to the water in the fire sprinkler pipes, the freezing point is much lower, reducing the risk of the pipes freezing.
What temperature should I winterize my sprinkler system?
To avoid any possibility of damage, sprinkler lines need to be drained prior to temperatures dipping below 32 degrees Fahrenheit. Failing to winterize a sprinkler system before a hard freeze (air temperature is below 0 degrees Fahrenheit) can lead to expensive and time-consuming repair costs.

What is the best time to turn on sprinklers?

Reinstall main valve bleeder cap (as needed). Slowly open the main valve. Test the system. Recheck the vacuum breaker and valves.
How do I know if my sprinklers are self draining?
Depending on the type of drain valve your system utilizes, draining could be truly automatic, or it could be manual, requiring that you pull a few levers to get things moving. One way to tell if your system is manual-draining is if your sprinkler heads have check valves on them.
How big of an air compressor do I need to winterize sprinklers?
You need a compressor that has either enough volume or large enough motor to fill your system with pressurized air. A compressor size of 4-6 gallons should be enough.
Should you winterize sprinkler system?

What is considered a hard freeze?
Hard freeze occurs when the temperature reaches 28°-or-lower for at least a few hours. It usually means that many types of plants and most seasonal vegetation will be destroyed.
