What size garbage disposal should I install?

The right size depends on household size and usage patterns. A 1/2 horsepower disposal works for small households, 3/4 horsepower handles typical families, and 1 horsepower is appropriate for larger households or homes that put significant volume through the disposal. Our team helps homeowners pick the right size rather than oversizing or undersizing for the actual use, since both create problems.

Which disposal brand does Roland Black recommend?

InSinkErator and Waste King are both reliable choices and dominate the residential disposal market for good reasons. Within each brand, the differences come down to grinding stages, sound insulation, and warranty length. Our plumbers walk through the trade-offs based on your specific household needs and budget rather than pushing a default brand.

How long does disposal installation take?

Most straightforward disposal replacements are completed in 1 to 2 hours, including removal of the old unit, mounting hardware updates as needed, electrical connection, and dishwasher inlet hookup. New installs in homes that don't currently have a disposal can take longer because of the additional work required to add electrical and dishwasher connections.

Can I install a disposal in a kitchen that doesn't currently have one?

Yes, though the install is more involved because of the electrical and dishwasher work required. Our licensed plumbers coordinate any needed electrical work alongside the plumbing modifications for the dishwasher inlet. The complete install is more involved than a replacement, but it's straightforward work for a properly equipped team.

Are quieter disposals worth the extra cost?

For households where the kitchen is open to a living space or shared with bedrooms above, the quieter premium models can be worth the upgrade. Sound insulation on premium disposals significantly reduces operating noise, and the difference is noticeable in everyday use. We walk through whether the upgrade makes sense for your specific situation rather than universally recommending the most expensive option.

Garbage Disposal Sizing Matters-Here’s Why

Sizing matters because an undersized motor strains on tougher scraps and jams repeatedly, while an oversized unit draws more electricity than the task requires. A properly sized disposal also fits into a broader waste-reduction habit-composting, reducing, and disposing thoughtfully together, seamlessly managing food waste at home. Our team helps homeowners pick the right size rather than defaulting to whichever model is on sale.

Disposal Installation Problems We Help You Avoid

Disposal installs done badly create leaks, electrical issues, and units that don’t perform as advertised. Here are the three most common installation problems we see when we see when we’re out in the field.

The sink flange seats the disposal to the bottom of the sink, and a poor seal at this connection leaks water under the cabinet with every use. Proper installation requires fresh plumber’s putty or the manufacturer’s specified gasket, plus proper torque on the mounting hardware. Our installs use the right sealing material and proper procedure to keep the connection watertight for the disposal’s full service life.

A disposal that doesn’t align cleanly with the existing P-trap creates strain on the drain connections and can cause slow drainage or back-pitched runs. Our plumbers verify drain alignment before final hookup and modify the drain configuration as needed. A properly aligned drain assembly is one of the things that makes a disposal install last.

Higher-horsepower disposals pull more current at startup, and an existing electrical supply that worked fine for the old unit may not handle the new one cleanly. We verify the electrical supply matches the new disposal’s specifications and update the connection as needed, including switch upgrades when the existing switch isn’t rated for the new amperage.

Roland Black handles every part of a disposal installation across Gastonia and Gaston County, from sizing through final testing.

Standard disposal replacements update the existing unit with a properly sized new disposal.
New disposal installs in homes without one include the additional electrical and dishwasher work.
InSinkErator, Waste King, Moen, and other major brand installations are handled with brand-specific procedures.
Mounting hardware updates ensure the new disposal seats properly to the sink flange.
Dishwasher inlet connections are made or updated as part of the install.
Electrical connections are made by appropriately qualified team members, with switch updates when needed.
Drain alignment is verified and corrected so the disposal discharges cleanly into the P-trap.

Several situations point to disposal replacement as the smarter move rather than another round of repairs.

The disposal has been jamming, leaking, or making unusual sounds on a recurring basis despite repair.
The unit body has visible cracks or signs of leaking from the housing itself.
The motor has burned out and replacement is more expensive than a new unit.
The disposal is more than 10 years old and showing multiple problems at once.
You want a quieter or more powerful unit than the existing model can deliver.
The disposal isn’t grinding food properly anymore, even after impeller cleaning.
You’re updating the kitchen and want a fresh disposal to match the new design.

Any of these reasons makes replacement worth pricing. Our team is happy to walk through the options with you when we’re with you on-site.
