ROANOKE COUNTY, Va. -

When the temperatures are in the 30s and 40s, you typically don't have to worry about pipes freezing, cracking, or bursting.

But on Monday night, temps are expected to get into the single digits and even below zero in some places.

That's why WDBJ7 called in a maintenance technician for some preps you can do to your home before the freezing temps arrive.

First things first, keep your thermostat to 70 degrees and nothing below. Maintenance Technician at Sunscape Apartments Jack Woomer says this is vital during single digit temperatures. "Many of the exterior walls have plumbing lines inside so you want the heat to permeate the wall and get back to the plumbing," explained Woomer.

If you plan on using a space heater for extra warmth, be sure it stays at least 3-feet away from anything combustible; wallpaper, bedding, clothing, and pets.

Woomer says there are also things you can do in the kitchen and bathrooms. "Leave the faucet on a small drip, not gushing, and open up cabinet doors so that you can get the heat back to these isolated areas."

Experts also suggest you learn how to shut off the main water supply.

In the event a pipe does crack or burst, this will help prevent further damage.

Usually shutoffs are located under the kitchen sinks, bath sinks, and behind the toilet. Woomer explains where the main water shut off is usually located in a house or apartment. "The main water shut off is usually near the water heater. If you can't find it there, trace the cold water line back to where it leaves the home and you'll usually find a gate valve or a ball valve that you can shut off."

Even though turning your thermostat up and letting your sinks drip may cost you a little more money now, it's better than forking out money to repair major damage.

It’s also very important to remember to be safe with space heaters.

About two-thirds of home heating fire deaths are caused by portable or fixed space heaters.
