Garbage Disposal Installation in Atlanta

The plumber starts with a site visit to inspect the disposal, test the drain, check the electrical supply (for new installations), and measure the space under the sink. They will take photos or notes to confirm the model, capacity and access, then provide a written, itemized quote that breaks down the service call fee, labor hours, disposal unit cost, any electrical work, permits, and disposal of the old unit.

Once you approve the quote, the plumber schedules the installation. On the day of the job, they turn off the power at the breaker, drain the trap, disconnect the old disposal (if replacing), and remove the mounting hardware. They install the new disposal by securing the flange under the sink, inserting the disposal motor and collar, tightening the locking ring, and reconnecting the P-trap and dishwasher drain line (if fitted). They verify the knock-out plug is removed and test the dishwasher connection.

The plumber then fills the sink with a few inches of water and runs the disposal to check for leaks around the drain flange, P-trap and dishwasher port. They restore power, test the disposal again, and check that it grinds smoothly and drains without backing up. They provide you with the warranty documents, user manual and care instructions. Typical cleanup takes 15–30 minutes.

Garbage disposals are rated by motor horsepower and design type. A 0.5 hp continuous-feed disposal is adequate for a single person or couple with light use; a 0.75–1 hp disposal suits a family or moderate daily use; a 1.5 hp disposal is ideal for heavy use, large households or if you want quiet operation and faster grinding. Continuous-feed models (the most common) run while you feed waste down; batch-feed models have a lid that you close before the motor starts, making them safer but slower. InSinkErator, Waste King and Moen are widely available brands with good reliability and parts support.

Access matters: if the disposal is mounted under a pedestal sink or in a tight corner, ensure the plumber has room to install and remove the unit. Noise is important too—larger motors and sound-dampened housings cost more but run quieter. If you have a septic system, check the disposal manufacturer's guidance; some septic systems struggle with disposals. If your kitchen has an island or unusual plumbing, ask the plumber whether a disposal is feasible. Most disposals come with a 5–7 year warranty; some offer lifetime warranties on the motor housing. Ask the plumber to compare options and warranties within your budget.
