How can debris be flushed from a newly installed ground loop?

To flush debris from a newly installed ground loop, first, connect a clean water source to the system and ensure all valves are open. Then, run water through the loop at a high flow rate to dislodge and carry away any debris. Monitor the water flow until it runs clear, indicating that the flushing process is complete. Finally, close all valves and check for any remaining contaminants before proceeding with the system's operation.
