Highly effective for clogs caused by hair, grease, paper, and other common debris. Widely applicable for unclogging kitchen sinks, washbasins, bathtubs, floor drains, and toilets in restaurants, hotels, households, and other settings. Does not damage sewage pipes (including PVC pipes) or electroplated surfaces.
If the clog is caused by oil or grease, it is recommended to use boiling water to flush the pipe. Of course, the effect will be better if you can use a professional sewage pipe unclogger. If the blockage is due to a foreign object, you can only rely on special pipe cleaning tools.
Insert a round wood with a diameter close to the inner diameter of the sewage pipe into the pipe. Fill the sink with a certain amount of water, then continuously and quickly pump the round wood up and down. Under the combined action of suction and pressure, the clogged dirt in the pipe will be flushed away.
