Maintenance Tips for Rinnai Tankless Water Heaters
Regular Inspection
Inspect your Rinnai tankless water heater every six months. Check for signs of wear, leaks, or damage. Look at the connections, pipes, and around the unit for moisture. Early identification of issues helps prevent bigger problems.
Cleaning the Filter
Cleaning the water filter keeps your system running smoothly. Turn off the water and power supply. Remove the filter, rinse it under water, and let it dry completely before reinstalling. Perform this maintenance every six months to one year.
Flushing the System
