Apply heating tape
If you have a pipe you are really concerned about or if you have a frozen pipe,
you will want to
have some heat tape (Electric Water Pipe Heat Cable) handy. Heat tape is easy to install. You can put it on the pipe like you see in the picture. You can tape it or zip tie it onto the pipe. If it is a bigger pipe, you will want to wrap it around.
In a weather situation where a lot of people are going to have frozen pipes, heat tape will go fast in stores. You don't want to be in a situation where you need it, and they are out of stock locally. If you anticipate that you may have an issue, buy it and have it on hand early. Even if you end up not needing to use it, you might be able to help a friend in need.
In the video, Chris discusses a property in Massachusetts that had pipes freeze during temperatures of -20 degrees. Heat tape and heaters in the area helped get the situation under control, and they insulated the pipes to prevent future issues.
Prevention is key. If you think you are going to have an issue, follow all the prevention steps to reduce the chance of having frozen pipes in your property.
Water shutoff valve
You want to be able to shut off any water source or pipe that is going out to the exterior spigots. If you don't have a water shutoff valve, you might consider having one installed. After you shut off the water going to the exterior spigots, make sure it is empty. Turn on the spigots and run out any water in the pipe.
Don't forget to insulate the main shut-off valve pipe as well.
