Daniel Hefner's family has been in the plumbing business for 96 years. Hefner says when the temperature dips below freezing, there are a few simple things homeowners can do to prevent their pipes from freezing and then splitting.
"What should they do if they've got parts of their home that they don't normally keep heated? Open the doors [to] introduce heat," says Hefner.
This goes for pipes under the sink as well. Opening cabinet doors can allow heat to access to the pipes.
Hefner says when it gets cold, like the weather expected in the Charlotte area, his company gets 10 to 20 calls a day about frozen pipes. He says the repairs can be quite costly.
Opening your cabinet doors, or letting your faucets drip instead of shutting them off completely will usually do the trick, but if you're unsure, Hefner is happy to walk his customers through the prevention process over the phone.
