Preparing your plumbing for winter is a critical way to stop it from being harmed during the year's coldest months. One of the most vital factors to consider is that of pipe insulation. Making sure all your exposed pipes are well insulated can mean the difference between won and lost plumbing come spring thaw.
Pay particular heed to pipes that are in unheated areas. Basements, attics—even tiny crawlspaces—can be frigid. Piping in those abominable places needs attention. If you have any kind of plumbing in an unheated garage, you should insulate those pipes as well.
Insulation of any kind that's not wet is good. Beyond that, you're free to use any kind of heat tape or even incandescent lightbulbs to warm up the plumbing systems in these potentially arctic places.
Another vital aspect of getting your plumbing ready for winter is making certain that the temperature inside your home is adequate. It is advisable to maintain the thermostat at a minimum of 55 degrees Fahrenheit, even when you are away from home. Many homeowners think that saving on heating costs necessitates some real ingenuity, but in our experience, that isn't true. If you try to cool down your indoor space to save on energy bills, the risk of having your plumbing freeze and then burst far outweighs whatever savings you achieved on your last utility bill. And by the way, opening up your cabinets is another energy-saving measure!
Letting heated air flow around the copper pipes that are part of your sink and faucet assembly is a great way to keep those parts from freezing, especially if they are located on an exterior wall.
Ultimately, the winter plumbing problem of water pipes bursting can be avoided by the simple step of keeping the plumbing system well maintained and always in optimal shape. The most prudent thing seems to be regular inspections of the plumbing, including scrutiny of the water lines that travel outside—in the parts of the plumbing that are most susceptible to freezing. The wise homeowner is also sure to check for leaks in the warm months, since the little drips of water that might seem insignificant also provide the kind of moisture that encourages mold and mildew to grow inside walls and under floors. And then there's the matter of outdoor fixtures.
