Ok, ok I know you’re all about sick of my preaching on this subject of #winterizingyourirrigationsystem BUT here’s what happens when you don’t:

When water freezes and changes to ice, it expands. This expansion is the real problem. If the depth of the frost reaches the sprinkler system components, the expanding ice may cause cracks in various parts of the sprinkler system.

If your #irrigationsystem was properly installed in Georgia at the recommended depth it is less likely that your pipes will experience breaks due to this cold. But ‘less likely’ doesn’t mean it can’t and won’t happen, as the ground gets hard and cold anything can happen with that pressure then expansion with warm up. Remember, your sprinkler heads are exposed. Your valves are hopefully in valve boxes but still exposed when the temperatures get this cold and the connection points are particularly vulnerable to these frigid temps as are all the connection points from irrigation lines to sprinkler heads.

Some sprinkler systems do have above ground parts that readily break when frozen. This includes both galvanized and PVC pipes and fittings. These are common repairs come spring time. Winterizing your sprinkler system annually will almost certainly save you money.
