With weather getting colder than your local infrastructure was really meant to handle, there's going to be more pipes freezing and bursting as time goes on. So from the front desk of a mitigation company:
Find out how to turn off the water in your house in case a pipe bursts and floods.
If you live in an apartment or multi-housing building, you will probably need your landlord or property manager's help, if you can do it at all (they will probably have to do it for you). Find the best number to call if something happens say, in the middle of the night, if something happens.
For the rest of you, you'll need to find the main water valve. Sometimes it's not even inside your house! Sometimes you have to go all the way to the street to find the little hidden box that contains the main water shut-off! And if you think you know but aren't sure, run a test! (Obviously coordinate with whoever owns the building if that's not you.)
The easiest way to keep a single-room flood from turning into a whole-housing flood is to turn off the water as fast as humanely possible. Even just a minute can make a difference when a pipe bursts!
By the time a home is hitting about 20 years old, you should be really starting to prepare for pipes breaking. The longer they go without breaking, the more likely it is every year that something will go wrong. Note the places you can see pipes or are certain pipes are, such as under your sink, behind the toilet, behind the refrigerator and washing machines, etc., and try to make game plans for if something goes wrong with each one. If any of those are on floors above ground level (or a basement), those repairs get even more costly because that damages both the floor and the ceiling below it-and could mean having to remove everything between the two layers, like subflooring and insulation because if insulation gets wet, it gets moldy.
Our company literally just had a job earlier today involving a poor distraught woman who couldn't do anything as her basement flooded with 2 inches of water because she had no idea where the water shut-off valve was; her husband had always taken care of things like that, and her husband passed away two years ago, and she never learned where the shut-off was. She had to call the fire department to help her out, because in addition to the water, her basement was full of electronic things and outlets, meaning it was an electrical hazard down there that only the fire department could even take care of. Even stepping foot in the basement to help her out could have risked the safety of our own guys.
Knowledge is power. Weather is getting more dangerous, so understanding the building you live in is going to be more crucial these days. Prepare for the worst, hope for the best!
