MADISON (WKOW) -- When the temperature drops below zero, water pipes in your home are in danger of freezing.
Experts at Action Plumbing in Sun Prairie say one way to avoid freezing is to insulate your pipes.
You can also open cabinet doors or use a fan to allow warm air to get to them if they're tucked away.
Another thing that's important is to know where your main shut offs are and make sure they work.
Experts say when ice builds up in your pipes, it can expand and lead to cracks.
"If you turn on a faucet and you have no water, the best thing to do is to open up the faucet a little bit. That will relieve the pressure off the faucet and in turn allow that ice to expand and the pipes won't split," advises Curt Johnson of Action Plumbing.
Johnson says you should also keep your garage door closed because many homes have plumbing for the laundry room or a nearby bathroom in the garage wall.
