Winter Plumbing Protection: Tips to Prevent Pipes From Freezing

Every winter, homeowners face the anxiety of potential plumbing disasters caused by dangerously low temperatures. A frozen pipe that bursts can result in severe water damage, massive cleanup efforts, and costly repairs. Securing the home’s plumbing before the cold of winter arrives is the most reliable way to maintain peace of mind. By taking preventive action now, homeowners can help avoid the stress and financial burden of a mid-winter frozen and burst pipe repair. This post will share some simple, effective measures to protect the plumbing during colder temperatures.

Insulate the Pipes

Plumbing lines situated in unheated or semi-heated zones, such as the basement, crawl space, attic, or garage, are vulnerable to freezing when temperatures drop. Pipe insulation creates an insulating layer that helps retain water’s heat and significantly slows the transfer of heat into the surrounding cold air.

This basic yet vital preparation is key to lowering the likelihood of a pipe burst due to freezing, which inevitably results in extensive water damage and expensive remediation. Ensure that all exposed sections of piping are completely covered. Pay special attention to joints and fittings, as these areas are most vulnerable to cold air infiltration. A modest investment of time and money in insulating these critical spots will offer protection throughout the winter months.

Maintain Interior Warmth and Open Cabinets

sinkMaintaining a steady temperature inside the home is one of the easiest ways to keep water flowing freely and prevent frozen pipes. Set the thermostat to at least 55°F during the colder months, even when the house is unoccupied. This will ensure that warm air consistently circulates throughout the home, reaching areas where plumbing may be concealed and serving as a necessary defense, keeping the water in the pipes safely above the freezing point. 

To maximize this protection, remember to open the doors of cabinets located beneath sinks and those housing any water supply lines. Plumbing against exterior walls is highly susceptible to external cold, and opening doors and cabinets allows the warm, circulating air from the heated living space to access and warm the pipes. This can help minimize the risk of frozen pipes and a plumbing crisis during freezing weather.

Winterize Outdoor Faucets

Plumbing fixtures located outside, such as hose bibs and outdoor spigots, must be prepped for winter before cold temperatures settle in. The water in these exterior lines is directly exposed to the cold and, if not properly drained and insulated, can freeze, causing the pipe to burst and leading to serious leaks and damage. Proper outdoor faucet winterization is a quick procedure that offers essential security for the plumbing system during the coldest part of the year.

Begin by detaching garden hoses from the outdoor faucets and completely draining any remaining water from them before storing them away. Next, locate the dedicated shut-off valve for the exterior faucet and turn off the water flow to that specific exterior line. After the water is turned off, open the outdoor spigot to allow any water in the line to drain fully. Finally, secure an insulating cover over the outdoor faucet to prevent freezing air from entering, keeping the pipe dry and protected all winter long.
