Wisconsin's cold snap is keeping plumbers busy with temperatures at or below single digits -- water pipes are at risk of freezing.
A plumber at one Wisconsin business says his company got 72 calls yesterday, mostly for frozen pipes. He says, on average, they get 30 calls a day, usually for clogs and other common plumbing problems.
He says as bad as it's been, the worst is yet to come. He warns that as temperatures warm up, the pipes thaw out and start leaking.
