How can you tell if you already have a frozen pipe? If you turn on a faucet and only a few drops come out, you probably have your answer. John Galeotafiore, who oversees Consumer Reports’ testing of home products and power gear, says “If you suspect the pipes are frozen, be careful when thawing them out because if the pipe has already burst, the water will come flowing out and flood your home.”
If you have a broken pipe, turn off the water at the main shutoff valve, which is usually at the water meter or where the main line enters the house. If the water is still running and no pipes have burst, take the following steps.
