The answer to 'sink frozen' is that a frozen sink drain is a common plumbing issue caused by cold temperatures or a blockage. Symptoms include slow or no water drainage, ice buildup around the drain, and potentially a frozen pipe. Solutions can range from DIY methods like pouring hot water down the drain or using a drain snake, to calling a professional plumber if the issue persists or the pipe is completely frozen.
Frozen sinks are typically caused by cold air exposure, such as from a window or open cabinet, or a blockage that prevents water from flowing freely. If the issue is caught early, DIY fixes may work, but if the pipe is fully frozen, it's best to call a plumber to safely thaw the line and address the root cause.
