Some simple tips can prevent frozen and burst pipes, according to the Kansas City, Kansas, Board of Public Utilities.
By running a pencil-thin stream of water overnight, customers may avoid frozen pipes, according to David Mehlhaff, BPU’s chief communications officer.
“Water expands as it freezes, placing tremendous pressure on whatever is containing it, including metal or plastic pipes,” he said. “Pipes exposed to severe cold, like outdoor hose bibs, water sprinkler lines and water supply pipes in unheated interior areas like basements and crawl spaces, garages or kitchen cabinets freeze most frequently,” he said. “The results can be both a nuisance and costly.”
Running the thin stream of water would use about two gallons of water an evening, which is less expensive than a frozen or burst pipe. Water saved from running a small stream could be used to water indoor plants.
Another tip is to open cabinet doors to expose pipes to warmer room temperatures to help keep them from freezing.
Additionally, eliminate sources of cold air near water lines by repairing broken windows, insulating walls, closing off crawl spaces and eliminating drafts near doors.
Customers should know the location of their main water shut-off valve. If a pipe freezes or bursts, shut the water off immediately.
Wrap exposed pipes with insulation or use electrical heat tracing wire; newspaper or fabric also might work.
If the pipes freeze, shut off the water immediately. Do not attempt to thaw frozen pipes unless the water is shut off. Freezing can often cause unseen cracks in pipes or joints.
Apply heat to the frozen pipe by warming the air around it, or by applying heat directly to a pipe. A hair dryer, space heater or hot water can be used. Do not leave space heaters unattended and avoid the use of kerosene heaters or open flames.
Once the pipes have thawed, turn the water back on slowly and check for cracks and leaks.
BPU advises that subfreezing temperatures may cause aging water mains to break and cause water to cover roadways. If you see a leak, your water service is disrupted, or you experience low pressure, contact the BPU’s water issues line at 913-573-9622 to report an emergency.
