It's not too late to winterize your plumbing.
In many places the winter cold is just getting started. If the busy holiday schedule kept you from preparing your home's plumbing for the cold, this is a good time to do it.
For starters, proper pipe insulation is an easy and cheap way to keep the water from freezing. A little work can help you prevent frozen pipes and the water damage they cause.
Winterizing is just one of the various plumbing maintenance chores that will help you prevent unnecessary plumbing problems.
