Auburn residence WH tune-up complete. 8yr Rheem unit in fair condition. Performed full flush & drain - removed approx 2 gallons sediment (more than expected). Replaced sacrificial anode rod which was severely degraded. Adjusted temp from excessive 140° to safer 125°. Tested pressure relief valve - functioning properly. Inspected burner assembly & gas connections using leak detector - all secure. Advised homeowner unit likely has 2-3yrs remaining life expectancy. Recommended budgeting for replacement within that timeframe. Left information on new efficient models.
