Performance and Reliability
Waste King residential units utilize motors between 1/3 and 1 horsepower and are meant for standard household use. While InSinkErator residential disposers offer the same horsepower range, commercial units can grind virtually any food product, offering motors with up to 10 horsepower. Residential InSinkErators come with MultiGrind® technology that reduces food scraps to small particles to lessen the chance of drain clogs, and optional LEDefense emits lighting in a spectrum that kills 99 percent of odor-producing bacteria.1
Design and Ease of Use
Waste King disposals come with easy-installation rings and are pre-wired for quick setup. Whirlaway units' lightweight and compact construction fits well in small sink areas, though they offer less sound protection. InSinkErator residential models also come with lift-and-latch technology for easy-installation. Likewise, commercial disposers are built with auto-reverse motors to prevent jams, enabling frequent and heavy use. Stainless steel and chrome-plated exteriors and leg supports help maintain sanitation and stability.
Maintenance and Durability
Waste King EZ Mount disposals use durable plastic mounting devices with galvanized steel grinding chambers. InSinkErator units primarily use stainless steel mounts and grinding chambers with cast nickel chrome cutting elements. While InSinkErator units typically require detailed installation, commercial units come with paint-free metal exteriors for simple cleaning and maintenance.
Cost and Value
Waste King garbage disposals are less costly than InSinkErator residential models. InSinkErator commercial appliances are much more expensive than both residential brands due to their stronger motors and extra-durable designs.
