From the City of Raymore:
We’ve got at least another week of freezing temperatures hanging around. Sustained frigid temps can freeze water pipes, which is not only inconvenient, but could lead to burst water pipes and a big, costly mess.
✔️ First, make sure that the cover for the water meter pit in your yard is closed securely. This will help keep cold air from freezing your meter.
✔️ Open cabinet doors under your sinks to get warm air circulating around those pipes, especially if your sink is located on an exterior wall.
✔️ Keep a trickle of cold water running through your faucet. This trickle should be a steady but small stream about the size of the lead in a pencil. Allowing the faucet to be on prevents pressure from building up in the system, which is the cause of burst pipes. (To run a small trickle for 24 hours costs less than 25 cents.)
✔️ Know where your main shut-off valve is located in case of an emergency. This can help you avoid a costly mess if a pipe should burst.
✔️ If a pipe freezes, never use an open flame to thaw it. Use a hair dryer, light bulb or heat tape. When in doubt, call your plumber.
