KRAUS WasteGuard KWD110-50MBL, 1/2 HP Garbage Disposal Key Features

Design & Build Quality

The KRAUS WasteGuard KWD110-50MBL 1/2 HP is built with longevity and quiet operation in mind. Instead of using cheap metals or thin housing, Kraus equips this model with solid stainless-steel grinding components inside a corrosion-resistant ABS body. That combination makes it both durable and quieter than many basic disposals. The stainless-steel impellers and grind ring resist rust and pitting over time, while the ABS shell helps absorb vibration rather than amplify it. The unit feels sturdy yet remains lightweight enough for easier installation. Its design clearly targets long-term reliability and a cleaner, quieter grind chamber — without sacrificing everyday usability.

Grinding Performance

Powered by a high-speed 3,800 RPM permanent-magnet motor, the WasteGuard delivers far stronger grinding performance than most traditional 1/2 HP induction models that usually top out around 1,700–2,600 RPM. The higher RPM helps pulverize food quickly into finer particles, reducing clogs and speeding up sink cleanup. It handles everyday kitchen waste such as vegetable scraps, soft bones (in moderation), fruit leftovers, cooked food waste, and plate scrapings with ease. While it doesn’t use multi-stage grinding like higher-end premium disposals, the WasteGuard feels responsive, efficient, and confidently capable for daily household needs.

Noise & Vibration

The WasteGuard’s standout feature is right in its name — ultra-quiet performance. Kraus uses an anti-vibration mounting system and a low-decibel motor design to significantly reduce noise and shake under the sink. You can run it while having a conversation in the kitchen without shouting, and it won’t rattle the sink like older disposals often do. While it’s not “silent,” the difference in comfort compared to standard 1/2 HP models is immediately noticeable. Its quieter operation makes it perfect for open kitchens, smaller homes, or late-night cleanup.

Installation & Ease of Use

Installation is one of the easiest parts of owning the WasteGuard. It uses the EZLock-style twist-and-lock mounting system, which fits standard 3½-inch sink openings and requires no special adapters. Kraus includes everything in the box: a factory-installed power cord, mounting flange, rubber gaskets, dishwasher connection, drain fittings, and even a sink stopper/plunger. Since no hardwiring is needed, most homeowners can install it in under an hour with basic tools. Once mounted, everyday operation is just as simple — turn on cold water, flip the switch, feed in scraps gradually, and let it run.

Motor Technology, Safety & Everyday Use

This model doesn’t just grind well — it protects itself, too. The motor-saving auto shut-off system stops operation in case of overload or jamming, preventing motor damage. After clearing the obstruction, a quick press of the reset button restores power. As a continuous-feed disposal, it allows you to add scraps while it runs, perfect for everyday cleanup. Kraus also notes it is septic-safe when used correctly, making it suitable for a wide range of households. An extended tailpiece helps push ground particles through the drain more effectively, reducing build-up in the plumbing and supporting smooth daily use.

Warranty

One of the strongest selling points of the KRAUS WasteGuard 1/2 HP is its impressive 5-year warranty—a level of coverage that rivals or even surpasses many well-known brands in this category. That alone adds peace of mind for long-term use.

But what truly enhances the overall value is what comes with it. This model isn’t just a basic disposer—it offers features that feel closer to a premium mid-range product, such as:

• Durable stainless-steel grinding components
• Quiet operation with sound-reducing design
• Factory-installed power cord (no wiring needed)
• Complete installation kit right out of the box
