Performed complimentary heat exchanger cleaning on tankless water heater as scheduled. Flushed the water side of the unit, removing a small amount of sediment from the heat exchanger. Disassembled the heat exchanger to clean internal channels. System is now functioning properly with no issues detected. Discussed potential water quality equipment upgrades with homeowners, who will monitor water quality for approximately one year due to recent road construction that may have contributed to sediment.
