Waste King L-8000, 1 HP Garbage Disposal key Features

Powerful 1 HP High-Speed Motor

The Waste King L-8000 is powered by a robust 1 hp permanent magnet motor that spins at an impressive 2,800 RPM. This high speed motor easily pulverizes tough food waste like vegetable peels and small bones in seconds. Its torque-driven performance prevents jams, ensuring smooth and efficient grinding every time you use it.

Continuous Feed Operation

With its continuous feed design, you can add food scraps while the unit is running no need to pause between loads. This makes it ideal for busy kitchens or large families where meal prep generates plenty of waste. The nonstop operation keeps your sink free flowing and makes cleanup quick and effortless.

Stainless-Steel Grinding System

Built with stainless steel impellers and a corrosion proof grind chamber, the L-8000 delivers long term durability and consistent grinding performance. These materials stay sharp and rust free even after years of daily use, ensuring smooth operation in wet and demanding kitchen environments.

EZ-Mount Twist-Lock Installation

Installation is quick and beginner-friendly, thanks to Waste King’s EZ-Mount twist-and-lock system. It includes a pre-installed 32-inch power cord, so no extra wiring is needed. Homeowners can easily complete setup in under an hour without professional help, making it one of the most convenient units to install.

Performance & Grinding Quality

In real world tests, the L-8000 handled a 90-oz mix of 11 foods in just two minutes, leaving less than 1 percent unprocessed. It easily grinds most waste from vegetable peels to chicken bones without jamming. While it’s a single-stage grinder (not multi-stage like premium models), its speed and power make it an efficient.

Noise Level & Ease of Use

The L-8000 comes with sound insulated housing that keeps noise levels manageable, though some users still find it louder than premium Insinkerator models. Noise depends largely on your sink and countertop material. Operation is simple – flip a switch, add waste, and it does the rest. While there’s no external jam release lever, it can be freed easily using an Allen wrench if needed.

Installation & Maintenance

Installation is straightforward with the EZ-Mount system and included hardware. Even first-time installers report finishing in under 45 minutes. The unit’s 16-inch height means you should check under-sink clearance before buying. The grind chamber is polymer and resists buildup run cold water and ice occasionally for best cleaning. It’s also certified septic safe for homes without city sewer lines.

Durability & Warranty

The L-8000’s stainless-steel grind components and polymer housing ensure long life and no corrosion. Many buyers report 10 years of use without leaks or rust. Its 20-year in-home limited warranty is the longest in its price range a clear sign of Waste King’s confidence in build quality.
