Outdoor pipeline cleaning: connect the cleaning equipment at the water source, connect the drain pipe at the end opening of the main pipeline, close the isolation valves of all branches along the line, and start the cleaning equipment for cleaning until it is clean. When cleaning the branch line, you can clean it separately or use the main line with the branch line. If the line is too long, it can be cleaned in sections.

Indoor pipeline cleaning: Connect the cleaning equipment to the outdoor household pipeline isolation valve, take the household faucet as the sewage discharge point, and clean it in units until all users finish cleaning.
