Short answer
For most kitchens the pick is the InSinkErator Evolution 0.75HP: InSinkErator’s product page lists a 3/4 HP Dura-Drive induction motor at 1725 rpm, 3-stage MultiGrind, Quiet SoundSeal insulation, stainless steel grind components and a 9-year in-home limited warranty. The budget pick is the InSinkErator Badger 5, the same maker’s 1/2 HP induction motor with a single grind stage, galvanized steel grind components and a 5-year warranty. The heavy-use pick is the Evolution 1.0HP at 4 grind stages and 10 years. Every InSinkErator tier this page checked names the same Dura-Drive induction motor, so the extra money buys grind stages, stainless parts, sound insulation and warranty years, not motor technology. Skip all of them if the house is on a septic system until you have read EPA’s advice to eliminate or limit a disposal, and choose a batch-feed unit such as the Evolution Cover Control, which runs only with its cover on, if small children reach the sink.
The picks
Most kitchens: wants quieter than a Badger without paying for the 1 HP
InSinkErator Evolution 0.75HP (Advanced Series)
InSinkErator's page: 3/4 HP Dura-Drive induction motor, 1725 rpm, 3-stage MultiGrind, Quiet SoundSeal, stainless steel grind components, 12.25 in tall, continuous feed, 9-year in-home limited warranty; page prints Cord Included: No
Replacing a Badger and wants the cheapest same-maker unit
InSinkErator Badger 5, 1/2 HP (no cord)
InSinkErator's page: 1/2 HP Dura-Drive induction motor, single grind stage, galvanized steel grind components, Quick Lock mount, 11-1/2 in tall, 6.3 A, continuous feed, 5-year in-home limited warranty; this listing is the no-cord version
A large household that runs the disposal after every meal
InSinkErator Evolution 1.0HP (Advanced Series)
InSinkErator's page: 1 HP Dura-Drive induction motor, 1725 rpm, 4-stage MultiGrind, Quietest SoundSeal tier on the chart, stainless steel grind components, 12.25 in tall, Lift and Latch, continuous feed, 10-year in-home limited warranty; page prints Cord Included: No
Wants 1 HP with the cord in the box from a second maker
Waste King L-8000, 1 HP (listed under Moen)
Amazon listing title only: 1 HP, power cord included; Waste King's site was down and no maker spec sheet was readable this session, so motor type, sound claims and warranty are not printed here
A rarely used sink or a tight cabinet where price decides
Waste King L-111 compact
Amazon listing title only: compact food waste disposer with power cord; no horsepower, motor type or warranty figure was readable from Waste King this session
Wants a batch-feed unit that only runs with the cover on
Moen GXB75C Host Series, 3/4 HP batch feed
Amazon listing title only: 3/4 HP, batch feed with control activation, power cord included, sound reduction claimed by the seller; Moen's site returned no readable product content this session
If the disposal under your sink hums and will not spin, this is the wrong page: a 1/4 inch Allen wrench and the red reset button fix that for nothing, so read the humming, not spinning guide first.
How was this shortlist built?
Every figure is a manufacturer-published specification read on 2026-09-27 from the page named beside it. Nothing was installed, run or listened to by this site. Listings were shortlisted from current Amazon listings, kept or rejected on the published spec, and confirmed in stock the same day.
Units were compared on horsepower, grind stages, motor type as the maker words it, sound insulation as the maker’s own tier name, warranty years, feed type, mount wording and whether the page prints a cord as included. No page read prints a decibel figure, so no decibel figure appears here.
The comparison is honest only for InSinkErator. Waste King’s site returned a server error on every page tried, and Moen’s product pages returned no readable content, so the Waste King and Moen units below carry only what their Amazon listing titles state: horsepower, feed type and cord. Their motor type, sound claims and warranty are gaps, not omissions.
A grind stage is one set of cutting or shredding elements the waste passes through before it leaves the chamber. An induction motor is the AC motor type InSinkErator names on its pages; no page read this session names a permanent magnet motor for any unit here.
How do the units compare on paper?
Manufacturer figures where a maker page was readable. “Not readable” means the maker’s page could not be opened this session and the cell is a gap.

Grind stages, sound tier, feed type and warranty for every InSinkErator row come from InSinkErator’s comparison chart; motor, rpm, cord and mount wording come from each product page.
InSinkErator Evolution 0.75HP: buy it or skip it?
Buy it if you want less noise than a Badger and a warranty that outlasts the cabinet. InSinkErator’s product page lists a 3/4 HP Dura-Drive induction motor at 1725 rpm, 3-stage MultiGrind, Quiet SoundSeal, stainless steel grind components, a 12.25 in height, continuous feed and a 9-year “We Come to You” limited warranty.
The flaw is the cord: the same page prints Cord Included: No, and the lineup page says the EZ Connect cord is sold separately. If the old unit was plugged in rather than hardwired, budget for the cord or the swap stops at the outlet.
Skip it if you are replacing a Badger and want a like-for-like drop-in: the Badger pages print a Quick Lock mount and the Evolution pages print Lift and Latch, and no InSinkErator page read states that one fits the other’s ring. The InSinkErator model cross-reference lays out the mount and height differences by model.
InSinkErator Badger 5: buy it or skip it?
Buy it if the kitchen is small, the budget is tight, or a Badger is what is coming out. InSinkErator’s Badger 5 page lists a 1/2 HP single-phase Dura-Drive induction motor, a single grind stage, galvanized steel grind components, a twist-on Quick Lock mount, 11-1/2 in height, 6.3 A, continuous feed and a 5-year in-home limited warranty.
The flaw is what the chart places it under: Standard Sound, the lowest of InSinkErator’s four tiers, and galvanized rather than stainless grind components. The Badger 5XP on the Badger Series page keeps the 1-stage grind but moves to 3/4 HP, stainless components and 6 years.
Skip it if the listing title does not say “with cord” and your old unit was plugged in. The Badger 5 page sells the unit both ways, and the listing linked here is the version without.
InSinkErator Evolution 1.0HP: buy it or skip it?
Buy it if the disposal runs after every meal in a large household. InSinkErator’s product page lists a 1 HP Dura-Drive induction motor at 1725 rpm, 4-stage MultiGrind, SoundSeal technology the chart files under Quietest SoundSeal, stainless steel grind components, Lift and Latch, 12.25 in height and a 10-year in-home limited warranty.
The flaw is that the step from 0.75HP to 1.0HP buys exactly one grind stage, one sound tier and one warranty year on the maker’s own chart, at the same 1725 rpm and the same 12.25 in height. A two-person kitchen pays for capacity it never fills.
Skip it if the cabinet is shallow: check the flange to cabinet floor clearance against the 12.25 in height before ordering.
Waste King L-8000 and L-111: buy them or skip them?
Buy the L-8000 if you want 1 HP with the cord in the box and are willing to accept a shorter spec sheet from this page. Amazon lists it as “Moen L-8000 Waste King 1 HP Garbage Disposal with Power Cord”, and the L-111 as a compact food waste disposer with a power cord. That is the whole of what this page can confirm.
The flaw is the missing maker page. Waste King’s site returned a server error on every path tried on 2026-09-27, so its motor type, sound insulation claim and warranty years are not printed here, and the “Moen” prefix in the listing title is not confirmed by any Moen or Waste King statement this page could open.
Skip both if a warranty figure is what you are comparing on. InSinkErator prints 5 to 10 years on its chart; for Waste King, this page has no number to put beside it.
Moen GXB75C Host Series: buy it or skip it?
Buy it if you want a batch-feed unit and the InSinkErator Cover Control’s Cord Included: No is a problem. Amazon’s listing title states 3/4 HP, batch feed control activation, a power cord and sound reduction. Batch feed means the unit runs only when its cover is in place, which is why it is the class to choose where children reach the sink.
The flaw is the same as Waste King’s: Moen’s product pages returned no readable content this session, so motor type, warranty years and the substance behind “sound reduction” are gaps.
Skip it if you would rather have the maker-documented batch-feed unit: InSinkErator’s Cover Control page lists a 3/4 HP Dura-Drive induction motor, 3-stage MultiGrind, a magnetic CoverStart switch for covered-only operation and a 9-year warranty, with the cord bought separately.
Read the old unit's label before you buy
Do not order a disposal until you know three things about the one coming out: whether it is plugged in or hardwired, which mounting ring is on the sink, and the height from the flange to the cabinet floor. The model cross-reference gives the InSinkErator mount wording and heights, and if the old unit only hums, the reset guide may end the shopping trip.
Who should skip a garbage disposal altogether?
Homes on a septic system, until two sources agree. EPA’s septic care page says to “eliminate or limit the use of a garbage disposal”, that this “will significantly reduce the amount of fats, grease, and solids that enter your septic tank”, and that if you must use one “your tank will need to be pumped more frequently” than the typical three to five years. InSinkErator’s pages say every unit here is safe for properly maintained septic tanks, that food scraps are 60-95 percent water, and cite a 2019 University of Minnesota study finding no more frequent pumping. The university page itself was not readable this session, so this page reports the maker’s citation, not the study. Ask the local health department and the pumper who knows the tank.
Anywhere the local code or utility restricts disposals. Plumbing codes are adopted locally and some jurisdictions limit or prohibit food waste disposers. No primary source naming a specific city was readable this session, so no city is named here: check with the building department before buying, not after.
Anyone without a disposal circuit. InSinkErator’s pages assume a switched outlet or a hardwire connection already exists. Adding a circuit is electrician and permit work.
What goes wrong?
It jams and hums. InSinkErator’s jam page: switch off, work a 1/4 inch Allen wrench in the bottom socket until it turns freely, let it cool, press the red reset button. That is maintenance, not replacement.
The new unit does not fit the old ring. The Badger pages print Quick Lock and the Evolution pages print Lift and Latch. Buying across the families without checking the mount is how a quick swap ends with a second order.
The cord is missing. Three of the Evolution product pages print Cord Included: No. A plugged-in kitchen needs the EZ Connect cord in the same order.
The septic tank fills faster. EPA says a disposal means more frequent pumping. Budget for it or skip the unit.
Frequently asked questions
Is a 1 HP garbage disposal worth it over 3/4 HP?
On InSinkErator's chart the step from the Evolution 0.75HP to the Evolution 1.0HP adds one grind stage (3 to 4), moves the sound tier from Quiet SoundSeal to Quietest SoundSeal and adds a year of warranty (9 to 10). Both product pages list a Dura-Drive induction motor at 1725 rpm. Pay for it if the disposal runs after every meal; a two-person kitchen does not need it.
What is the difference between continuous feed and batch feed?
InSinkErator's lineup page defines it: a continuous feed disposal is powered by a wall or air switch and runs until all food is fed through, while a batch feed disposal has the switch in its cover, so it runs only when the cover is on. The Evolution Cover Control is InSinkErator's batch-feed model; the Moen GXB75C Host Series is listed as batch feed.
Can I use a garbage disposal on a septic system?
EPA's septic care page says to eliminate or limit the use of a garbage disposal, and that if you must use one the tank will need pumping more often than the typical three to five years. InSinkErator's pages say its units are safe for properly maintained septic tanks and cite a 2019 University of Minnesota study. Ask your local health department and your pumper before buying.
Does a new InSinkErator come with a power cord?
It depends on the model. InSinkErator's Badger 5 page offers the unit with or without a factory-installed cord, which is why the listing title matters. The Evolution .75HP, Evolution 1.0HP and Evolution Cover Control pages print Cord Included: No, and the lineup page says the EZ Connect cord is sold separately. The Septic Guard page lists an EZ Connect power cord and hardwire adapter.
Do I need a new disposal if mine hums but will not spin?
Usually not. InSinkErator's jam page says to switch off, work a 1/4 inch Allen wrench in the socket on the bottom until it turns freely both ways, let the unit cool, then press the red reset button. That costs nothing and takes minutes. Buy a replacement only if the housing leaks or the overload trips repeatedly after a clear.
Fact sheet and how to cite this page
- Answer
- The pick for most kitchens is the InSinkErator Evolution 0.75HP: InSinkErator’s product page lists a 3/4 HP Dura-Drive induction motor, 3-stage MultiGrind, Quiet SoundSeal and a 9-year in-home limited warranty. The Badger 5 is the budget pick at 1/2 HP, 1 grind stage and 5 years; the Evolution 1.0HP is the heavy-use pick at 4 stages and 10 years. All three name the same induction motor family.
- Comparison basis
- InSinkErator’s garbage disposal comparison chart and its Badger 5, Evolution .75HP, Evolution 1.0HP, Evolution Cover Control and Evolution Septic Guard product pages for horsepower, motor type, grind stages, sound tier, feed type, mount, cord line and warranty; Amazon listing titles only for the Waste King and Moen units, because neither maker’s site was readable this session.
- Assumptions
- The sink already has a disposal circuit or a switched outlet; a new circuit is electrician and permit work
- The reader is on a municipal sewer, or has read the septic section and EPA’s advice before choosing any unit
- Sound insulation is compared only as the maker’s own tier names (Standard Sound, Reduced Sound, Quiet SoundSeal, Quietest SoundSeal); no decibel figure is printed on any page read
- Method
- OwnerSpec compared manufacturer-published specifications read on 2026-09-27 and confirmed each listing in stock the same day; it did not install, run or listen to any disposal, and it prints only the specs the cited page states.
