InSinkErator PRO750, 3/4 HP Pro Series Garbage Disposal Key Features
Design & Build Quality
The InSinkErator PRO750 was engineered to combine power with precision. Its space-saving body makes it ideal for smaller under-sink areas, without compromising performance. The chamber’s stainless steel grind components offer excellent corrosion resistance and long-term durability, while the premium finish gives it a polished, professional look.
This unit’s Quiet Collar Sink Baffle and reinforced sound insulation reflect InSinkErator’s commitment to a quieter kitchen environment. Despite its power, the PRO750 fits comfortably under most sinks, leaving room for cleaning supplies or plumbing connections.
Grinding Power & Everyday Performance
With a 3/4 HP Dura-Drive induction motor, the PRO750 offers robust grinding strength, capable of handling daily kitchen waste with ease. Thanks to 2 stage grinding technology, it grinds food twice first breaking it down, then refining it into smaller particles that easily flush away.
This dual stage system helps prevent jams and clogs, even with more challenging scraps like celery fibers, melon rinds, or small bones. It’s an excellent choice for households that cook frequently but still want an efficient, low-maintenance waste solution.
Noise & Vibration
Where the PRO750 shines is it’s SoundSeal technology, reducing noise by up to 40% compared to standard models. Combined with the Quiet Collar Sink Baffle, it absorbs vibration and prevents sound from echoing through the sink.
While not completely silent, it’s impressively quiet for a 3/4 HP disposer. You can carry on a conversation or run the disposal without disturbing the kitchen’s peace.
Installation & Ease of Use
The InSinkErator PRO750 arrives ready for easy installation, thanks to its included power cord and Quick Lock mount system. Whether you’re replacing an older InSinkErator or installing it from scratch, setup is straightforward.
The unit connects easily to standard plumbing configurations, and its compact design ensures a snug fit under the sink. With its Lift & Latch feature, aligning and securing the disposal is a one person job, and no extra hands required.
Simple Operatrion: Daily operation is simple: run cold water, flip the wall switch, and feed scraps gradually.
