2. Find a small saw blade, insert it into the broken wire of the water pipe and pull it constantly, then smash the broken wire with a hammer.
3. Use a special broken wire extractor. Screw the broken wire extractor into the broken wire first, so that the broken wire is wound on the extractor, and then screw it out with a wrench.
The water pipe is a water supply pipe. Modern decoration water pipes are built by burying walls. There are three types of water pipes. The first category is metal pipes, such as hot-dip cast iron pipes lined with plastic, copper pipes and stainless steel pipes. The second type is plastic-coated metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes. The third category is plastic pipes, such as PB pipes and PP-R pipes. Concealed engineering is a very important problem. If the water pipe leaks and bursts, it will bring irreparable consequences. In the past, the pipes used for water supply were mainly cast iron pipes. Sand cast iron pipes are mainly used outdoors, and galvanized cast iron pipes are used indoors. However, after several years of use, it is easy to produce a lot of rust and scale, breed bacteria and seriously endanger human health. The state stipulates that from June 1 2000 onwards, sand casting process pipe fittings and cold galvanized cast iron pipes will be eliminated, the use of hot galvanized cast iron pipes will be gradually restricted, and aluminum-plastic composite pipes and new plastic pipes will be popularized. The state also stipulates that all kinds of pipes and fittings involved in drinking water pipelines must be approved by the health department before they can be sold.
