Water Heater Service Performed maintenance and repairs on the existing electric water heater. Drained and flushed the tank to remove accumulated sediment and debris. Removed and replaced the upper and lower heating elements and installed a new anode rod to help protect the tank from internal corrosion and extend the service life of the water heater. Refilled the water heater, checked all serviced connections for leaks, restored power, and verified proper operation at the time of service.
