Tanked water heater maintenance. 1st visit of 3 on service club membership. • Drain water heater • Inspect burner • Verify no gas or CO leaks • Relite pilot light • Verify no water leaks • Purged air from home • Check expansion tank • Clean and reinstall fresh air screens • Cap drain valve • Verify operation of water heater • Purge air from recirculating pump Suggestions: The expansion tanks bladder has ruptured and should be replaced. Average lifespan of an expansion tank is 1-2 years. Service club members get a 1 year warranty on leaks or ruptures. Replace expansion tank today. Due to unit being drained already I could honor the price of a level 3 at $162
