The answer to 'sewer camera inspection frozen' is that a frozen sewer camera inspection is often caused by extremely cold temperatures. The camera and cable can become stiff and unresponsive when exposed to freezing conditions, making it difficult or impossible to perform the inspection. This is a common issue during the winter months in colder climates.
If your sewer camera inspection is frozen, the best solution is to wait for the equipment to warm up to room temperature before attempting to use it again. Bringing the camera and cable indoors to a heated space can help thaw them out. You may also want to insulate the equipment or use a portable heater to keep it warm during the inspection. If the problem persists, it's best to call a professional plumber who can properly diagnose and address the issue.
