Happy is the person who does not have a clogged sewer in the house. And those who have faced such a problem know that clearing the clog is not so easy without special devices. Instead of the usual cables, which must be twisted by hand, you are offered a spring, which will be twisted by your electric drill. The system is simple: you need to stick the end of the spring into the pipe, connect the other end to the drill and press the button. The spring will go inside the pipe and spinning will break through the clog. The length of the spring is 4 meters. It is made of stainless steel, so corrosion is not terrible. The outer diameter of the spring is 16mm. The diameter of the wire is 1mm.
