Responded to customer report of a stoppage on the kitchen line. Accessed and snaked the kitchen drain line through the cleanout located on the exterior wall of the kitchen sink. Water was run continuously throughout the snaking process to ensure the line was fully cleared and flowing properly. Verified that the blockage was resolved and that the drain was functioning correctly. Recommendation: Advised customer to consider replacing the existing water heater due to its age and potential risk of failure. See attached estimate for replacement details and pricing.
