The answer to 'how does drain cleaning work' is that drain cleaning is the process of removing debris, buildup, and blockages from residential or commercial plumbing systems. This is typically done using specialized tools and techniques to clear clogged drains and restore proper water flow.
Drain cleaning often involves using a plumber's snake or auger to physically break up and remove the clog, or using high-pressure water jets to flush out the pipes. In some cases, chemical drain cleaners may be used to dissolve organic matter and clear the blockage. Professional plumbers also have access to more advanced tools like video inspection cameras to identify the location and nature of the clog.
