Garbage disposal installation is a common handyman job when a switched outlet already exists under the sink. The project includes removing the old disposal (or sink drain basket), installing the new mounting assembly with plumber's putty, hanging the disposal unit, connecting the discharge tube to the P-trap, wiring the power cord, and testing the unit. We install disposals from 1/3 HP to 1 HP. If a new electrical outlet or switch is needed, we coordinate with an electrician. The dishwasher drain connection is included if applicable.

Gustine is located in Merced County (San Joaquin Valley). Tiny dairy-farming community with affordable older homes and rural lots. The local utility provider is PG&E.
