What do you do if your pipes still freeze, despite your best preventative measures? First step: Don’t panic. Just because they’re frozen doesn’t mean they’ve already burst. Here’s what you can do:
If you turn on your faucets and nothing comes out, leave the faucets turned on and call a plumber.
Do not use electrical appliances in areas of standing water: You could be electrocuted.
Keep the doors on the bathroom/kitchen sinks open so that the warmth from the house travels here too.
Never try to thaw a pipe with a torch or other open flame because it could cause a fire hazard. Water damage is preferable to burning down your house!
If your water pipes have already burst, turn off the water at the main shutoff valve in the house; leave the water faucets turned on. Make sure everyone in your family knows where the water shutoff valve is and how to open and close it.
