Just completed a garbage disposal installation for a customer in College Park. The previous unit had completely seized up after 8+ years of service. Customer opted for the InSinkErator Evolution Excel 1HP model with sound insulation. Removed the old unit, thoroughly cleaned the sink flange area, and installed the new mounting assembly with fresh plumber's putty. Connected to existing drain lines with minor modifications for proper alignment. Added a new dedicated GFCI outlet under the sink for safety compliance. Tested the unit thoroughly - running smoothly with no leaks or unusual vibration. Also tightened loose connections on the sink's faucet as a courtesy. Left the area clean and provided customer with operation instructions and maintenance tips. They were very pleased with the quieter operation of the new unit compared to their old one.
