Sewer pipes from buildings can be connected to the main sewer by cutting a hole in the main line and then inserting a pipe. If the drain pipe is put too far into the sewer main, it won’t have the necessary clearance to drain properly. when this happens it is called a protruding tap, or protruding service, and can pose a problem in sewer main cleaning. A protruding tap cutter is a tool with a specially designed cutting bit used to cut through the protruding tap which leaves only a amount of pipe inside of the main. This removes the restriction in the line, allowing it to flow normally. With the main line clear it is possible to use the water jetter to complete the sewer cleaning services as usual.
