With frigid temperatures and wind chills expected in the coming days, the Kentucky Division of Water reminds citizens to protect the water systems in their homes and businesses from freezing.

When water freezes, it expands. When water freezes in a pipe and expands enough, the pipe bursts, water escapes and serious damage results. Pipes in attics, crawl spaces and outside walls are all vulnerable to freezing, especially if there are cracks or openings that allow cold outside air to flow across the pipes.

To keep pipes from freezing, wrap hot and cold water pipes in insulation or layers of newspaper, covering the newspapers with plastic to keep out moisture. Allow a trickle of water to run from a cold faucet that is farthest from the water meter or one that has frozen in the past. This will keep the water moving so that it cannot freeze and will help relieve pressure should ice form in the pipes. Open kitchen and bathroom cabinet doors to allow warm air to circulate around the pipes.

If pipes freeze, remove the insulation, completely open all the faucets and pour hot water over the pipes or wrap them with towels soaked in hot water, starting where they are most exposed to the cold. You may also use a hand-held hair dryer or electric heating pad if there is no standing water. Apply heat until full water pressure is restored.
