-Ensure you have a source of heat in the location where pipes are located.
-If your pipes are located in a crawl space without heat ensure they are properly insulated.
-Have a small heater to use in an emergency if you need to thaw lines.
-Leave your cupboard doors open if your pipes are located on an outside wall.
-Check your pipes during very cold weather. If the pipes freeze, thaw, freeze, thaw they could cause a breakage such as the one in the photos where the pipe was literally broke apart.
-Ensure that you have water shut off valves (such as the one with the blue handle) so that IF you did have a leak or breakage you would not have to shut off all your water to your entire home.
-If you know you are going to be away for an extended period of time OR are without hydro/heat ensure you have some antifreeze on hand to winterize your pipes and prevent any breakage.
