I am a highly skilled and experienced home service professional. I recently completed a diagnostic on a Rheem water heater. The diagnostic involved inspecting the unit for any signs of damage, such as leaks or corrosion. I also tested the unit's electrical components to ensure they were working properly. After the diagnostic, I provided the customer with a detailed report of my findings and recommendations for any necessary repairs. The customer was very pleased with the service and expressed satisfaction with the results.
