The water pipe is rusty. What should I do?

Secondly, it is suggested that all pipes involved in rust should be replaced locally. Thirdly, the material of sand and gravel is likely to corrode metal pipes, so it is recommended to use plastic pipe products. Products like Wei Xing, Sorbonne, Jinde and Rifeng are all good choices. Finally, it is suggested to use silk fittings at both ends and PPR water pipes in the middle after water supply is stopped. I hope I can help you. Follow-up: Because there is no thread at both ends of the intercepted water pipe. A: There is a special tool to suppress the thread opening. My father made that thing when he was in the machinery factory, but if you dig 1-2 bricks, it will be difficult to press the thread mouth, because the pipe needs to be fixed on the base to press the thread mouth, because it is more powerful. Show the residential property first, or consult the hydropower company. I can't see the construction site, and there are pipes leading out. Only from the experience, the specific operation still needs to be operated.
