Preventing busted pipes during this deep freeze is a reality every homeowner is hit with right now.
To keep the water flowing "inside" pipes experts recommend insulating.
If it's too late for that right now, they say keep a "trickle" of warm water dripping overnight from a faucet on an outside wall.
Set your thermostat at the same temperature around the clock and open cabinet doors so heat can reach uninsulated pipes under sinks and appliances near exterior walls.
It's a situation plumber Scott Dugan knows all too well.
"My phones have been ringing off the hook. But I can't do nothing for them," he says. "A lot of these are frozen underground. Just make sure you know where your main valve is to shut your water off."
Dugan says it's either going to be at the meter, out towards the street or even in the house.
But knowing the location of your main shut-off valve is key so you don't flood your house.
