Winterizing to Prevent Winter Damage
There are many things to think about when Winterizing your Irrigation system.
Do I have a Automatic or Manual Drain Valve to empty the water out of my system, or will I have to use an Air Compressor to blow out my lines.
Should I turn my controller off for the winter or just restrict the winter months from watering?
These are important considerations when it comes to water Freezing/Mildewing in pipes.
Draining Irrigation Pipes of Water
Turn the Water Source that feeds the Irrigation System off. Some systems have a Automatic/Manual Drain that releases excess water in the lines when not in use.
If this is not present, many people use the "Blow Out Method".
This is where you Turn Off the Water to your Irrigation system and enable the Valve/Zone closest to the Water Main and run an Compressed Air through the lines for no longer then 2 minutes a zone. This is important since you would not want to Stress the valve any more then needed. Once you have completed 2 minutes on the first zone, you then move to the next closest at 2 minutes each until you have completed all your zones.
To power down or not to power down, that is the question.
This can be handled different ways, and each has its own benefits. By leaving it powered on and restricting the winter months you do not want to water can allow the unit to continue to calculate based on the weather, and allow it to receive updates. View more on Restrictions here.
