I began by ensuring the power to the tankless water heater was turned off to maintain safety. I then accessed the water heater's internal components, carefully removing any sediment or mineral deposits that had accumulated over time. Using a garden hose, I flushed the system thoroughly, ensuring all contaminants were removed. I checked for any leaks or damage during the process and made necessary adjustments. After flushing, I refilled the system with fresh water and turned the power back on. I tested the water heater to confirm it was functioning correctly and provided the customer with detailed instructions on maintaining the system to prevent future buildup.
