1/2 HP vs 3/4 HP by Household, Matching the Mount and the Cord, and the Three Places a Disposal Leaks
5 picks compared · prices, ratings and stock checked October 13, 2026
Our Top Pick
For a like-for-like swap on an existing InSinkErator mount, the InSinkErator Badger 5 1/2 HP Continuous Feed Garbage Disposal. For a household of three or more, or daily prep with peels and trimmings, the InSinkErator Badger 5XP 3/4 HP Continuous Feed Garbage Disposal with Power Cord. Put an under-sink mat and a leak sensor beneath whichever one you fit.
4.6 on Amazon · 20,057 ratings
Quick answer
The best garbage disposal is a 1/2 HP continuous feed unit that fits the mount already under the sink; for an existing InSinkErator, that is the InSinkErator Badger 5 1/2 HP Continuous Feed Garbage Disposal, rated 4.6 stars across 20,057 Amazon ratings. If three or more people eat in most nights, step up to the 3/4 HP InSinkErator Badger 5XP. Buy a corded model if the old unit plugged into an outlet and one without a cord if it was hardwired. First find where the old one leaks: a drip at the flange or dishwasher inlet is a joint to reseal, while a wet base means the body has failed.

Our take
The Badger 5 is the disposal most people are replacing, which is the point of buying it again: the listing says it fits existing InSinkErator hardware, so the sink flange and mounting ring already under your sink can stay and the new body twists onto them. That turns a messy afternoon into a short job. Two things to check before you order. This listing ships without a cord, so it suits a hardwired install; if your old unit plugged into an outlet, you need the corded version or a cord kit. And the grind components are galvanized steel, per the listing, not stainless, which matters in a kitchen where acidic scraps sit in the chamber. Run cold water for a few seconds after every grind so nothing sits there.

Suited to
A household of three or more, or a cook who peels and trims daily, with an outlet under the sink
Our take
Stepping from 1/2 HP to 3/4 HP buys more torque for the loads that stall a smaller motor: a bowl of potato peels, melon rind, the fibrous ends of celery. The 5XP keeps the Badger footprint, 12.63 in high by 6.31 in wide per the listing, so it fits where a Badger 5 did. This listing also states stainless steel grind components, which the plain Badger 5 listing does not, and it ships with the flange and gasket set, so you can replace a tired old flange rather than reuse it. The 4-year warranty is stated outright. It is still a single-stage grinder, so treat it as the same machine with a stronger motor, not a finer grind. Keep the cold tap running the whole time it spins.

Our take
Waste King's L-1001 is the long-running alternative to a Badger for people who want stainless grind parts and a cord without paying for a 3/4 HP motor. The listing names a 2,600 RPM permanent magnet motor; this type comes up to speed almost instantly, and the maker's claim is that the speed clears scraps before they wedge. The trade-off is that the EZ Mount is its own system. If you are replacing an InSinkErator, the old flange comes out and the new one goes in with fresh plumber's putty, which is the fiddly part of any disposal job. Its 5-year in-home warranty is longer than the Badger 5XP's stated four. Read the cabinet height before you buy, because the listing gives no dimensions.

Moen GXP50C 1/2 HP with cord: stated septic-safe with a properly sized tank, on a mount the listing says replaces most brands.

Pros
Cons
Suited to
A home on a septic system, or a kitchen where the old disposal was a different brand
Our take
A disposal on a septic system sends ground food into the tank, where it adds to the solids the tank has to hold between pumpings. That is why most listings say nothing about septic use, and why Moen's wording matters: the GXP50C is stated as safe with a properly sized septic tank, which puts the condition on your tank rather than on the machine. If your tank was sized without a disposal in mind, ask your septic service before adding one, and expect to pump more often. The listing also says the mount replaces most existing disposals, including other brands, which helps when the old unit is a mystery. What it leaves out is the grind material and the dimensions, so check both when it arrives.

Pros
Cons
Suited to
An open-plan kitchen where the disposal runs during conversation, or a home with a long drain run that clogs
Our take
The Evolution is the pick when noise or a slow drain, not motor size, is the complaint. The listing describes three grind stages, with the aim of grinding scraps finer, and a finer grind matters most on a long horizontal drain run under a kitchen floor, where coarse pieces settle and build up. The sound claims are stated without a decibel figure, so the honest reading is quieter than a standard InSinkErator, not a number. It is 8.25 in wide per the listing, about 2 in wider than the Badger 5XP, so measure between the trap and the cabinet side. The removable dishwasher inlet plug saves a common mistake: a knocked-out disc dropping into the chamber, or a plug left in place so the dishwasher cannot drain.

What to know before you buy.
Dry the unit with a towel, lay paper on the cabinet floor, and run the sink. Water at the rim where the disposal meets the sink is the flange: the plumber's putty under it has dried out or the mounting ring has loosened, and resealing it costs an hour, not a disposal. Water at the side, timed with the dishwasher draining or the sink emptying, is the dishwasher inlet hose or the drain elbow, both fixed with a clamp or a gasket. Water beading at the base plate or the reset button, with everything dry above it, is the internal seal between the grinding chamber and the motor. On most residential disposals that seal is not a part you can buy and fit, and by the time it shows the housing is usually corroding, so the answer is a new unit. Whichever leak you find, press the cabinet floor with a thumb before you buy anything.
Horsepower on a disposal box is a nameplate figure. Two listings read for this page, Waste Maid and American Standard, print the same disclaimer: horsepower claimed on the package does not indicate motor output or the power applied to grinding. So compare motors, not just the number. InSinkErator's Badger and Evolution lines use a Dura-Drive induction motor; Waste King, Moen and Waste Maid name permanent magnet motors at 2,600 to 2,700 RPM, which reach full speed almost at once. As a sizing rule, 1/2 HP serves one or two people and light cooking, and GE's own listing for its 1/2 HP Disposall recommends it for 2 to 4 person homes. Three or more people eating in most nights, a cook who peels and trims daily, or a double-bowl sink in steady use points to 3/4 HP, which is where the Badger 5XP and the Evolution sit. A 1 HP unit suits a large household or a drain that has clogged before, and none made the list.
The mounting assembly decides whether the swap takes twenty minutes or an afternoon. InSinkErator units use a twist-on mount the listings call Quick Lock, and the Badger 5 listing says it fits existing InSinkErator hardware: leave the old flange and ring in place, twist the old body off, twist the new one on. Waste Maid's listing describes a standard 3-bolt mount as a direct replacement for most brands that use 3-bolt mounting. Waste King and Moen name an EZ Mount, and Moen's listing says it replaces most existing disposals including other brands, which means the new flange goes in. Crossing families means pulling the old flange, pressing fresh plumber's putty under the new one, and tightening the ring from below. Every pick here that lists its box contents includes the flange, gaskets and bolts. Measure the height from the sink bottom to the cabinet floor and the width beside the trap before you order; the Evolution is 8.25 in wide per its listing, the Badger 5XP 6.31 in.
If the old disposal plugs into an outlet, buy a corded unit and the swap needs no electrical work; the Waste King, Moen and Badger 5XP picks ship with the cord fitted. If a cable runs straight into the old unit's base, it is hardwired, and the plain Badger 5 and the Evolution are built for that, the Evolution with an EZ Connect hardwire adapter in the box. Switch the breaker off and test that the wires are dead before you open the junction box. Adding a new outlet or switch is electrical work that many local codes treat as a permit job for a licensed electrician. The other connection people forget is the dishwasher inlet. If a dishwasher drains through the disposal, the plug inside that inlet has to come out before installation, or the dishwasher fills its own tub on the first cycle. The Evolution listing describes a removable plug; on most units you knock it out and fish the disc from the chamber.
Every disposal on this page is continuous feed: it runs from a wall switch and takes scraps while it is spinning, which suits cleanup after cooking. A batch-feed disposal only runs when its stopper is seated in the opening, so nothing can fall or be dropped in while it turns; it is the usual choice where no switch is wired near the sink or where small children reach it. No batch-feed unit was among the listings read for this page, so if that is what you need, shop that type by name. Septic is the other condition to settle first. Ground food adds to the solids a septic tank has to hold, and most listings say nothing about it. Two do: Moen's GXP50C is stated as safe with a properly sized septic tank, and GE's Disposall listing calls itself septic safe. Treat that as the maker's statement, ask your septic service whether your tank was sized for a disposal, and plan on more frequent pumping if it was not.
Do not buy a disposal because the old one drips at the flange or the dishwasher inlet; those are seals and clamps to redo. Do not buy one to fix a sink that drains slowly or backs up, because a disposal grinds food finer but does nothing for a line clogged past the trap; snake the drain first. Call a licensed plumber when the drain stub is corroded into the wall, when the trap arm has to be moved, when the leak is behind the cabinet back rather than under the unit, or when local code wants a permit for the work. A cabinet floor that is already soft or dark is a drying job before it is a plumbing job: the EPA's mold guide says to dry water-damaged areas within 24 to 48 hours to prevent mold growth, and swollen particle board rarely dries on its own. The restoration line on this site reaches a water damage company for that drying, not a plumber for the disposal.
YesFor a household of one or two people with ordinary scraps, and GE's own 1/2 HP listing goes further, recommending it for 2 to 4 person homes.
The limit shows up with fibrous waste, peels in bulk, and anything you would hesitate to put down the sink anyway. If the household is three or more and someone cooks from scratch most nights, 3/4 HP spares you the jams. Remember that the box figure is a nameplate, not grinding output, as the Waste Maid listing itself says.
It is worth it when the extra torque will actually be used: three or more people, daily prep with peels and trimmings, or a double sink in steady use. Among the picks, the Badger 5XP gives the stronger motor in the same body as the Badger 5, and the Evolution pairs it with three grind stages.
For one or two people with a 1/2 HP unit that has never jammed, the step up buys little, and the Evolution at 8.25 in wide may not fit the cabinet the Badger did.
A like-for-like swap on the same mount with a corded unit is a home job: unplug, support the body, twist it off, twist the new one on, reconnect the drain elbow and the dishwasher hose, then run water and check every joint with a paper towel.
Hardwired units add a junction box, which means breaker off and a tester before you touch a wire. Call a plumber when the drain stub into the wall is corroded, the trap has to be rebuilt, or your local code requires a permit; call an electrician for a new outlet or switch.
Only with a tank sized for one, and only the maker's word says so for a given model. Ground food is extra solids the tank must hold, so a disposal on an undersized tank means more frequent pumping or, over time, a clogged drain field.
Of the picks here, Moen's GXP50C states it is safe with a properly sized septic tank; the InSinkErator and Waste King listings say nothing either way. Ask the septic service that pumps your tank before adding one.
A continuous feed disposal runs from a wall switch and accepts scraps while it turns; a batch feed disposal runs only when its stopper is seated in the sink opening, so the chamber is covered whenever the motor is on.
Batch feed is the safer type around small children and the practical one where no switch is wired near the sink. All five picks on this page are continuous feed, because no batch feed unit was among the listings read for it.
Longer than the warranties stated on these listings, which run 4 to 5 years; many units go well past them. The end usually shows one of two ways: water beading at the base, which is the internal seal and means replacement, or a motor that hums, trips its reset button and stops.
Cold water during and after every grind, no grease, and no fibrous waste in bulk are what stretch the years. A unit that has started leaking from the base is replaced, not repaired.

An under sink mat is a silicone or plastic tray that keeps drips and spilled cleaners off the cabinet floor, but it holds only what its raised edge allows and can hide a slow leak. These picks are compared on size, stated edge height, trimming and cleaning, with the capacity math, the monthly check and the leak sensor a mat still needs.
