How to deal with rust and leakage in traditional tap water iron pipes

1. If the iron water pipe with a diameter of 2 cm is leaking but there is no embroidery on the iron water pipe and only some parts are damaged, first we should close the main valve of the water pipe, then replace the iron water pipe at that position, and then cut off the water pipe at that position. For the water pipe, we then use a wire-cutting instrument to cut the thread buckles, and finally connect the connectors.

2. If an iron water pipe with a diameter of 2 cm leaks, it is because all the water pipes are corroded. Then we can first close the main valve of the water pipe, and then replace all the water pipes in this section and tighten the screws on both ends.

3. If the iron pipe with a diameter of 20 cm leaks because there is a problem with the connecting joint, then just replace the connecting joint. If the pipe itself is leaking, the only solution is to remove the embroidery on the original pipe itself and then repair it by welding. (It should be noted here that an iron plate that closely fits the water pipe must be embedded at the repair location for reinforcement.
