InSinkErator Power .75 HP Garbage Disposal Review (3/4 HP)

InSinkErator Power .75 HP (3/4 HP) Garbage Disposal Review

Quick take: The InSinkErator Power .75 HP, Power Series EZ Connect garbage disposal hits a really nice sweet spot – noticeably quieter and smoother than the old-school Badger units, with more torque for tough scraps, but without the price tag of a premium Evolution model. If you want a modern 3/4 HP workhorse that’s easy to install and still fits under most sinks, this is the Power Series model to beat.

Amazon shows strong recent sales and a solid customer score around 4.6 out of 5 stars from hundreds of ratings, with most owners praising how quiet, powerful, and easy to install it is.

Why homeowners like the Power .75 HP

• Quieter than the “old clunkers”: Several buyers upgrading from 10–20 year old Badger-style units are surprised at how much quieter this Power model is, even when grinding tougher scraps.
• Fits modern kitchens: The compact 12" height and slimmer body make it easier to tuck into tight under-sink spaces, including slide-out cabinet setups and busy IKEA-style kitchens.
• Serious grinding power: The 3/4 HP Dura-Drive motor and 2-stage MultiGrind system are designed to power through tougher items – owners mention handling things like peach pits and everyday hard scraps without drama.
• EZ Connect install: Lift & Latch mounting, the hardwire adapter, and the removable dishwasher inlet plug are all designed to make DIY installs achievable for confident homeowners.
• Septic-friendly option: It’s rated safe for properly maintained septic systems, which is important if you’re upgrading an older septic-compatible unit.

2-Stage MultiGrind – how it actually helps

One of the biggest upgrades over basic disposals is the 2-stage MultiGrind® system. Instead of a single grind pass, the Power .75 HP uses:

• Stage 1 – Grind: The MultiGrind ring tackles everyday food scraps, breaking them into small, drain-friendly pieces.
• Stage 2 – Shear: A second GrindShear® stage sends food through shearing windows to break it down even finer, which helps reduce the chance of clogs in the line.

That second shear stage is a big part of why this unit is marketed as “designed to prevent clogs compared to standard one-stage grinders.” It’s especially useful if your household regularly runs fibrous or slightly tougher scraps (within InSinkErator’s recommended food types).

Noise and day-to-day use

Owners repeatedly describe this unit as quiet and powerful. One customer who replaced a long-serving 3/4 HP Badger commented that the Power model is not only quieter, but also smoother and easier to live with day to day. Another reviewer who runs it daily noted that it grinds quickly without the rattling or harsh noise they were used to.

Is it whisper-silent like a top-end Evolution model with full sound insulation? No. But for the price bracket, the Power .75 HP is impressively refined – especially if you’re upgrading from an older builder-grade disposal.

Real owner feedback (summarised)

• Long-term InSinkErator loyalty: One buyer replaced a 12-year-old Badger 3/4 HP with this model and felt confident choosing InSinkErator again because the old unit lasted so long.
• Noticeably quieter: That same owner reported that the new Power unit is clearly quieter than the Badger it replaced, with smoother operation.
• Easy DIY install: Multiple reviewers mention swapping out their old unit in a short evening – no major plumbing changes required, and the Lift & Latch mount helps hold the weight while tightening.
• Great under-sink fit: One reviewer specifically mentioned it fitting into a slide-out IKEA sink cabinet where other disposers interfered with the pull-out tray.
• Solid build quality: Users frequently describe it as sturdy and well built, feeling like a step up from older “thin” disposals.

On the flip side, some owners wished the unit included a power cord in the box rather than requiring a separate purchase, and a few reported confusion around the electrical connection if they weren’t comfortable wiring appliances.

What we like about the Power .75 HP

• Excellent power-to-price ratio: 3/4 HP with 2-stage grinding and stainless components is a very strong spec sheet at this price.
• Compact and kitchen-friendly: 8.25" x 12" footprint leaves more room under the sink for bins, filters, or slide-out storage.
• Modern EZ Connect design: Lift & Latch, hardwire adapter and removable dishwasher inlet plug make replacement installs simpler.
• Rust-resistant stainless steel grinding parts: Designed for long-term durability even with regular use.
• Septic safe and USA-assembled: Good box-tickers for environmentally conscious and “buy local” households.
• Strong warranty: 6-year in-home “We Come To You” service coverage adds real peace of mind.

Things to consider before you buy

• Cord usually sold separately: In most listings this Power Series model does not come with a pre-attached cord. If you want a plug-in install, budget for an InSinkErator power cord kit or plan to hard-wire it.
• Heavy for one-handed installs: A few owners mention that, because it’s a solid unit, you may appreciate a helper or a support stack under the sink while mounting.
• Not the quietest in the lineup: If you’re extremely noise-sensitive, consider stepping up to an Evolution series model with full sound insulation.
• Follow food guidelines: MultiGrind helps with tough scraps, but you should still avoid non-food items and use common-sense food waste practices.

Who is the Power .75 HP best suited for?

This model is an excellent fit for:

• Busy family kitchens that want a strong mid-range disposer to handle daily food scraps without sounding like a jet engine.
• Upgrades from older 1/2 HP or basic builder units where you’ll really notice the jump in power and refinement.
• Homes with limited cabinet space that still want 3/4 HP performance without a giant canister under the sink.
• Existing InSinkErator owners looking for a modern replacement that keeps the familiar mounting style.

If your household tends to cook a lot, deals with heavier scraps, or you just want a little extra overhead, also take a look at the InSinkErator Power 1 HP. For pros and remodelers, the Contractor 1000 1 HP (hardwire) and Contractor 1000 1 HP with cord give you heavier-duty 1 HP options in the same broader family.

Installation tips and accessories

If you’re replacing an existing InSinkErator unit, you may be able to reuse the sink flange and mounting collar if they’re in good condition, but many homeowners take the opportunity to refresh all visible parts for a clean look.

• Power cord: For plug-in installs, match this disposer with an official InSinkErator cord kit (see our Power Cord Kit Guide).
• Dishwasher connection: If you plan to connect a dishwasher, the EZ removable dishwasher inlet plug makes the job easier. For more detail, see our Dishwasher Connector Kit Guide.
• Sink baffle upgrade: Want even better splash control and a bit more noise reduction? Check out our Sink Baffle & Stopper Guide for compatible upgrades.

Basic DIY install flow (summary)

1. Turn off power at the breaker and unplug or disconnect the old disposal.
2. Remove the existing unit and mounting assembly, clean the sink opening, and install the new sink flange if needed.
3. Wire the Power .75 HP via the EZ Connect hardwire adapter or attach an approved power cord kit.
4. Lift the unit into place using the Lift & Latch system to hold it while you rotate the mounting ring to lock.
5. Attach the discharge tube to the P-trap, connect the dishwasher hose if applicable, and check all joints.
6. Restore power, run water, and test for leaks and smooth operation.

If you’re not comfortable with electrical work or plumbing, it’s always best to hire a licensed professional – the cost is usually modest compared to the lifespan of the unit.

Seth’s verdict on the InSinkErator Power .75 HP

If I had to pick one Power Series model to feature as a “go-to” recommendation for most households, this would be it. You’re getting:

• 3/4 HP torque with 2-stage MultiGrind
• Quieter, smoother operation than standard disposers
• A compact footprint that plays nicely with modern cabinetry
• Stainless steel grinding components and a generous 6-year in-home warranty

The main caveats are the separate power cord and the usual weight of a solid 3/4 HP disposer during install. If you’re okay with those, the InSinkErator Power .75 HP is a fantastic upgrade for a busy, modern kitchen and a strong flagship for the Power Series line.
