My first year owning an in ground sprinkler system. We live on the Gulf Coast. Anything I need to do before the first freeze? (I realize our ground doesn't freeze during the winter) Do I need I need to drain the sprinkler system?
Thanks!
Thanks!

I live in Tupelo & all I do is turn the rainbird controller to off. I did have to replace one fitting that froze & cracked two winters ago. We didn't get above freezing for 5 days. Cost me $1 for the fitting & maybe 20 minutes to fix.

I've never winterized my irrigation and seems to be fine.

The underground lines are fine like previously stated but you should protect all above ground PVC and backflow preventer

Make sure to drain your irrigation pump if expecting a hard freeze, that’s about it for irrigation.

Turn water off at the back flow and drain that. Put a insulated bag on it and you should be good to go

If your valves are exposed to freezing temperatures, shut off supply and manually open the valve outflow. Water freezing in a closed valve may rupture the diaphragm. Replacement is an easy fix.

Block in and drain your vacuum breaker. Should be sufficient.
After freezes we would repair lots of vacuum breakers, it was a good stream of income in the winter.

They suck when they bust. Ironically, mine busted when it was 28F, but not when it was 7F

Go ahead and order a backflow preventer or two ahead of time, you'll need it eventually. Put covers on all your hose bibs, and an insulating "bag" over the backflow preventer assembly. And if you have a heated pool, drain the heater. That was the only freeze casualty I had in 15 years.
