Homeowner requested installation of a new kitchen sink and faucet that she had purchased. Upon evaluation, we determined the existing drainage required updates to meet current code requirements and ensure safe, reliable performance; once the work was approved, we removed the existing sink, faucet, and drain piping, cleaned and prepared the installation surface, installed the new sink with proper waterproof sealing, and re-piped the drainage system. After completion, the work area was cleaned and all connections were tested, confirming proper operation with no leaks observed at this time. We diagnosed a leaking lavatory faucet and identified worn hot and cold cartridges as the cause. Replacement cartridges have been ordered, and we will return at a later date to install them and restore reliable, leak-free operation.
