2. Open the door of the pump hopper, clean the concrete in the hopper, then close the door, fill it with water, insert the cleaning ball into the pipe and draw water until the cleaning ball and clean water flow out.

3. Remove all pipes and rinse with water until clean.

4. Use tools to block the nozzle and then disassemble the connecting elbow, open the air source to let the concrete in the pipeline sprayed out from the end. Then you can add water to the tube or use the accelerator pump to pump the water. At last add a cleaning ball and open the blockage. (this method must make sure that surrounding workers are at a safe distance).
