Winterizing fire sprinkler systems


Last winter I was in Florida when we were hit at home by snowzilla. There were reports of extended power outages nearby so I sweated
it out by calling neighbors and in the middle of the nite by calling my answering machine to see if the power was out for any extended time.
I was concerned with the damage that could be done by a frozen fire sprinkler system. I assume it will freeze and burst, is that correct?
Any idea how long it would take? In my previous house, I would just turn the HWH and water supply off before I left. I think I recall that
my house insurance requires me to keep the water supply on for the sprinkler system. Can anyone provide advise as to what I should do.
We pretty much spend 2-4 weeks down south during every jan/feb.
thanks

Where in Florida are you located? Not many parts of Fl stay cold enough long enough to freeze pipes.

I was in Florida on Vacation. I'm a snow bird. It freezes pretty good in northern MD.

A simple solution is to install a stand-by power generator.

It keeps the power on to run the heat for your MD. home, when and if the Grid goes down.

I wouldn't call that simple.

You can have antifreeze installed in the system.

The residential sprinkler systems I saw used a special plastic tubing in place of pipe and I would be averse to putting any type of antifreeze in it. Probably best to consult the company that installed the system. The thing I would never want to fool with an insurance policy.
