If the water drains but slowly, the freeze is likely further down the line. If it doesn't drain at all (standing water), the freeze is close. If you have access to a crawlspace or basement, inspect the exposed pipes. Look for frost or a bulging appearance.
Few winter plumbing problems are as frustrating as a frozen drain pipe. Unlike a frozen supply pipe (which brings water into your home), a frozen drain pipe prevents wastewater from leaving . This means sinks, toilets, showers, and washing machines can suddenly back up, creating a messy, unsanitary situation.
For severe or recurring freezes, you can buy a self-regulating pipe heating cable. Wrap it around the frozen pipe according to the manufacturer’s instructions and plug it in. These cables gently warm the pipe over several hours.
Once the water is flowing again, take steps to ensure it doesn't happen twice. Insulate exposed pipes with foam sleeves or fiberglass wrap. During extreme cold, leave your cabinet doors open to allow warm air to circulate around the plumbing. Finally, keeping a tiny, pencil-lead-thin trickle of water running through the pipes can prevent the water from standing still long enough to freeze.
