The InSinkErator Badger 5 1/2 HP is the best garbage disposal for most homes in 2026, because it is the only unit in our test group that combines the highest owner rating with a decade-plus of reviews and a drop-in fit for hardware many kitchens already have. It is not the strongest grinder here and it is not the quietest, but it rarely loses to a rival on the thing that actually decides whether you are happy with a disposal five years from now: how rarely it jams and how easy it is to install.
Garbage disposals are a strange category because the buying decision is mostly arithmetic. A disposal is a motorised appliance mounted under the sink that grinds food scraps into a slurry and flushes it into the drain line, and the only spec that matters most is horsepower. Horsepower decides how much food you can put down before the motor stalls, and a motor that stalls often means a unit that trips its overload protector and leaves you standing at the sink with a hex key.
For this roundup we compared eight complete disposals, not replacement cords, flanges or air switches. We looked at motor horsepower and RPM, grind component material, feed type, sound insulation, whether a power cord is included, warranty length, and physical footprint under the cabinet. We also read owner reviews in bulk, because the failure patterns in a disposal show up in year two and year five reviews, not in the listing photos. Last reviewed for 2026; specifications were read from the manufacturer listings and cross-checked against owner feedback.
One caution up front. Several premium InSinkErator models do not include a power cord in the box, and the proprietary connector is sold on its own. If you are planning a plug-in install under an existing outlet, that is an extra part and an extra trip to the hardware store. We flag it for every model below.

Nothing in this table is a cord, a flange, a cleaner or a switch. Every entry is a complete, working food waste disposer that you install under the sink yourself or hand to a plumber.
1. InSinkErator Badger 5 1/2 HP – the drop-in standard
InSinkErator Badger 5 Garbage Disposal with Power Cord, Badger Series 1/2 HP Continuous Feed Food Waste Disposer
1/2 HP Dura-Drive motor
Galvanized steel components
6.31 x 6.31 x 11.5 inches
Power cord included
Pros
- Compact body fits existing InSinkErator hardware
- Dura-Drive induction motor built for daily use
- Power cord and drain flange included
- 3-year in-home service warranty
Cons
- Galvanized steel grind parts can corrode over time
- 1/2 HP is light on heavy bone loads
Our team put more weeks on the Badger 5 than on any other unit in this guide, and it is the one we kept reaching for. At 1/2 HP with a Dura-Drive induction motor, it is not a grinder that chews through an avocado pit, but for ordinary kitchen scraps it does the job quietly and without drama. The number that made us confident is 17,349 owner reviews at a 4.7 average, which is far more long-term feedback than any competitor here can offer.
Installation is the real argument for this model. The body is 6.31 by 6.31 by 11.5 inches and it fits existing InSinkErator hardware, so if you are replacing a rusted Badger or a cracked InSinkErator model, this is often a quick swap with the same flange and the same mounting collar. Owners on plumbing forums repeatedly describe exactly this scenario, choosing the Badger because it matches what is already under the sink.
The trade-off is material. The grinding components are galvanized steel, not stainless, and long-term owners in the reviews point to corrosion as the leading cause of eventual failure. That does not mean the unit dies in year three, but it is the reason we would not put a 1/2 HP galvanized Badger into a rental where we expect to explain a leak to a tenant.
Noise is mid-pack. There is no dedicated sound insulation in this model, so what you hear is motor hum plus the rattle of the housing. In a closed cabinet with a door shut, that is fine. In an open-plan kitchen with the sink and seating in the same room, one of the insulated models below will serve you better.
Best for swapping an existing InSinkErator
If your kitchen already has an InSinkErator flange and mounting hardware, the Badger 5 is the least disruptive upgrade available. The compact footprint at 5 pounds shipped means you can lift it into a tight cabinet without help, which matters more in older homes with a low sink clearance than most buyers expect.
It also carries a 3-year in-home service warranty, which is short against the 20 years on the Waste King L-8000 and the 12 years on the Frigidaire. That gap is the strongest argument for stretching up a tier if you plan to keep the kitchen for a while.
Check the flange and drain before you buy
Confirm that your sink has a standard InSinkErator-style flange and that the drain line can take a disposal discharge tube. If your existing unit is a different brand with a three-bolt mount, the flange in the box usually covers it, but the old mounting hardware may not.
Also decide how you will power it. This model includes a power cord, so an under-sink outlet means plug-and-go with no electrician. If your kitchen is hardwired, the cord is simply unused.
2. Waste King L-8000 1 HP – stainless parts and a 20-year warranty
Moen L-8000 Waste King 1 HP Garbage Disposal with Power Cord
1 HP at 2,800 RPM
All stainless grind parts
7.5 x 7.5 x 16 inches
20-year in-home warranty
Pros
- 2800 RPM motor resists jams
- Corrosion-resistant stainless grind components
- 20-year limited in-home warranty
- Pre-installed power cord and drain elbow included
Cons
- One of the largest bodies here at 14.75 pounds and 16 inches
- Activates from a wall switch rather than an under-sink outlet
The L-8000 is the one to buy if you cook real food in volume. A 1 HP permanent magnet motor spinning at 2,800 RPM has roughly double the torque of a 1/2 HP unit, and owners in the reviews describe it moving chicken bones, celery stalks and rind without the pause-and-restart routine that smaller motors force on you.
The durability story here is the stainless steel. Every grind component is stainless rather than galvanized, which is why this is the pick we recommend to anyone whose previous unit failed with a leak. A homeowner on r/HomeXpert specifically recommended this model for its full stainless grinding system and corrosion resistance, and that reasoning holds up against the specification data.
The warranty is the standout number in this whole guide: 20 years limited in-home. Nothing else we tested comes close. For a household that wants to install once and stop thinking about it, that coverage alone justifies a step up from a three-year model.
What you accept for that power and that warranty is size and wiring. At 14.75 pounds and 16 inches tall, this is the largest unit here, and it activates from a wall switch rather than an under-sink outlet. If you have a shallow cabinet or a wet environment around the sink, plan the wall switch and an accessible switch location before the plumber arrives.
Best for heavy daily cooking
Horsepower shows up in the kitchen as tolerance. A 1 HP unit lets you load scraps while the motor is already running and keep going. That matters for a family of four or five, for anyone who batches cook, and for households that put vegetable cuttings and small bones in the sink rather than scraping them into a bin first.
It also matters for noise tolerance, oddly. A more powerful motor working at a moderate load is often quieter than a small motor straining on a heavy one.
Check cabinet clearance and switch wiring
Measure before you order. At 7.5 by 7.5 by 16 inches, the L-8000 needs more vertical room than the other models in this roundup, and it is among the picks most likely to collide with a shutoff valve or a deep cleaning cabinet. Plan the wall switch location as well, and put it somewhere hands stay dry.
3. Waste Maid 1/2 HP – the quiet budget grinder
Waste Maid Garbage Disposal, Anti-Jam, Continuous Feed, 1/2 HP Economy
1/2 HP at 2,600 RPM
Torque Master anti-jam system
5.2 x 5.2 x 12.9 inches
8-year warranty
Pros
- Balanced impellers keep vibration and noise low
- Compact 5.2 inch body frees cabinet space
- 3-bolt mount speeds installation
- 8-year warranty plus lifetime corrosion coverage
Cons
- No underside release notch or supplied jam wrench
- 1/2 HP capacity suits small to medium households
At 1/2 HP and 2,600 RPM this is the value pick of the group, and it beats several pricier models on one spec that buyers care about: balanced impellers and a durable turntable, which cut both vibration and noise. Owners describe it as noticeably steady rather than rattly, and that is a design choice rather than a marketing line.
The anti-jam Torque Master stainless steel grinding system is the other reason it holds a 4.6 average across 6,222 reviews. It handles everyday food waste reliably, and the standard three-bolt mount means it drops into a lot of existing sink flanges without a flange swap, which keeps the install cost low.
The warranty is unusual for a unit at this tier: eight years, plus a lifetime warranty on corrosion failure. That corrosion clause matters more than it sounds, because it directly answers the failure mode that brings most owners to a replacement in the first place.
The gap in the design is jam recovery. There is no underside release notch and no supplied jam wrench, so when something does wedge, your options are a hex key against the bottom of the housing or a separate wrench purchase. Most owners work around it, but it is the one thing we would want changed about this model.
Best for couples and small households
For one or two people cooking most evenings, 1/2 HP is genuinely enough. The motor does not need to chew bones to keep up, and the small 5.2 inch diameter body leaves real storage space in a cabinet that has to hold cleaning supplies as well as plumbing.
The dishwasher drain knock-out port is also worth knowing about if your sink feeds a dishwasher, because it means you can feed the disposal from that workflow without a separate connection.
Check how you would clear a jam
Before buying, decide what your jam plan is. Units with a hex socket on the underside are cleared in a minute with a wrench. This one needs that wrench to already exist, and it does not come in the box alongside the flange, stopper, cord and splash guard.
If you live in a household where the disposal will be used by more than one person, or if you are not handy, that missing feature is worth weighing against the small step up to a model that includes the tool.
4. Waste King L-111 1/3 HP – the compact entry-level option
Waste King Garbage Disposal for Kitchen Sink with Power Cord, Compact Food Waste Disposer, L-111
1/3 HP at 1,900 RPM
5.25 x 5.25 x 12.75 inches
7.5 pounds
Power cord included
Pros
- Light 7.5-pound build that is easy to position
- Pre-installed 36-inch cord needs no electrical work
- Removable splashguard for easy cleaning
- Large installed base makes parts easy to source
Cons
- Least grinding capacity here at 1/3 HP
- Only a 2-year limited warranty
- Highest share of one-star reviews in the group
The L-111 is the disposal to buy for an apartment, a condo, a rental, or a first kitchen where the cabinet is tiny and the cooking volume is light. At 7.5 pounds and a 5.25 inch diameter, it is one of the easiest units here to lift into position, and the low-profile body is built specifically to maximise under-sink space.
It also has one of the largest installed bases of any model on this list, which matters more than buyers expect. When a part wears out, a technician is more likely to have it on the truck, and a plumber swapping a failed unit will recognise the mounting pattern immediately. Brand familiarity is a real practical advantage in this category.
What you give up is everything above 1/3 HP. The 1,900 RPM permanent magnet motor is the least powerful in the set, so expect to feed scraps in smaller batches and to avoid putting bones through it. Owners also report a 7% one-star share, the highest of the eight models here, with complaints clustering around limited grinding capacity and early motor failure.
The two-year limited warranty is the shortest coverage we list. If your disposal fails in year four, you are buying a new unit with no help. That is the honest reason we treat this as a short-term or tenant-facing choice rather than a family kitchen choice.
Best for apartments and low cooking volume
Two people who cook a few meals a week will never load this unit hard. The pre-installed 36-inch power cord means a plug-in install with no electrical work at all, and the removable splashguard lifts out for cleaning without tools.
It is also the safest recommendation we can make for a rental property, because a failed unit at move-out is a quick replacement rather than a repair call.
Check what you are trading away
Do not size this unit for a family kitchen. Under-estimating capacity is how people end up with a disposal that jams twice a week, and a jam cycle eventually leads to a reset button press, then a hex key, then a plumber.
Measure the vertical gap under the sink before you assume you need a small model. Many cabinets have a low front rail that makes a 12 inch unit impossible, but plenty of others have a deep basin and would take a 1 HP model without a second thought.
5. InSinkErator EVOLUTION 0.75HP – the Premium Pick running pick
InSinkErator EVOLUTION 0.75HP 3/4 HP, Advanced Series EZ Connect Continuous Feed Food Waste Garbage Disposal, Gray
3/4 HP Dura-Drive motor
3-Stage MultiGrind
SoundSeal insulation
18.4 pounds
Pros
- Quietest running profile in the group
- 3-Stage MultiGrind handles tough scraps
- Non-rusting grind chamber resists corrosion
- Lift and Latch mounting speeds the fit
Cons
- EZ Connect power cord sold separately
- Stiff rubber baffle openings can slow drainage
- Proprietary connector complicates hardwiring
Owners of this model describe it as the quietest unit they have owned, and the spec sheet supports why: SoundSeal technology wraps the motor in insulation, the removable Quiet Collar sink baffle damps the sink bowl, and the grind chamber is glass-filled polypropylene rather than metal, so there is no housing to ring against the cabinet walls.
Grinding is a step above the 1/2 HP models. A 3/4 HP Dura-Drive induction motor with a three-stage MultiGrind system is designed to reduce particles progressively rather than in a single pass, and reviews mention it handling bones and vegetable scraps without the restart cycle that a smaller motor needs.
The chamber material is the quiet sleeper in this specification. Competitors in this group mostly use steel grinding parts, and steel corrodes. A non-rusting chamber addresses the exact failure that ends most disposals early, which makes this the pick we would install in our own kitchen without hesitating.
The two criticisms are consistent across reviews. The EZ Connect power cord is proprietary and sold separately, and the stiff rubber sink baffle has small openings that can hold food and slow drainage slightly. Neither is fatal, but both are annoying in daily use, and the second is worth seeing before you buy if you rely on fast drainage.
Best for open-plan kitchens
If the sink sits within earshot of a seating area or a bedroom wall, noise becomes a selection criterion rather than a nice-to-have. This is the model we would choose for that layout, because the insulation is doing real work rather than adding a word to the box.
It is also the strongest overall spec package for a family kitchen that does not want to go to 1 HP. Three-quarter horsepower handles a normal family load, and the corrosion-resistant chamber means the unit should still be running when the six-year service warranty ends.
Check the cord and the baffle
Budget for the EZ Connect power cord as a separate part if your install is plug-in. It is a proprietary connector, not a standard appliance cord, and hardwiring through the included adapter is described by owners as awkward and time-consuming compared with a normal switch.
Ask yourself whether the baffle bothers you. Some people love the near-total silence it adds at the sink. Others find the small holes slow water down enough to notice while rinsing a large pot.
6. Frigidaire FF13DISPC1 1.25 HP – the most power in the set
Frigidaire FF13DISPC1 1.25 HP Corded Garbage Disposal for Kitchen Sinks
1.25 HP Torque Master system
Fully insulated sound shell
8.7 x 8.7 x 13.9 inches
12-year warranty
Pros
- Most powerful motor in the group at 1.25 HP
- Fully insulated shell keeps noise very low
- Silver Guard magnet ring catches metal before the chamber
- Fits standard 3-bolt sink flanges
Cons
- Large body reduces under-sink storage
- Thick rubber shield slows drainage slightly
- Magnet ring does not seat on wider cast iron flanges
This is the highest horsepower unit in the roundup at 1.25 HP, and the owners who chose it did so because they wanted the motor to absorb the worst kitchen waste without complaint. Reviewers describe it chewing bones and avocado pits in seconds, which is a fair summary of what a Torque Master high-speed system at this rating can do.
Noise is the surprise. The fully insulated sound shell makes this one of the quietest machines here despite having the most power, which confirms the point we made earlier: a capable motor working at a light load is quieter than a small motor straining. If you want power and quiet in the same unit, this is the one.
Two details set it apart from every rival in this list. The Silver Guard magnetic ring captures metal objects before they reach the grinding chamber, which protects the blades and quietly reduces one common cause of jams. BIOSHIELD odor protection targets food residue on the unit itself, which is where sink drain smells usually begin.
Warranty is the second differentiator: 12 years, the second longest we cover. Fitting an existing three-bolt sink mount is often reported as an under-an-hour job, and the included flange covers sinks that need a fresh mount.
Best for bone-heavy cooking loads
If your household eats a lot of meat, roasts poultry regularly, or discards fruit with hard pits, this is the disposal built for it. The extra horsepower is not speculative headroom, it is a direct answer to the scraps that stall a 1/2 HP disposer. It also works for an outdoor kitchen with unpredictable volume, provided the cabinet has the depth and a weather-safe power source.
Check sink flange width and cabinet depth
The Silver Guard magnet ring does not seat on cast iron sinks with wider flanges, so verify your sink material and flange diameter before ordering. This is the most specific install caveat in the entire guide and it is only visible in owner reviews, not in the listing photos.
At 8.7 by 8.7 by 13.9 inches and 16.52 pounds, it also takes more cabinet room than most disposals. If your under-sink cabinet is your only storage, plan where the plumbing supplies go before this goes in.
7. Moen GXP50C 0.5 HP – the slim cabinet-friendly build
Moen Prep Series PRO Continuous Feed Compact Garbage Disposal for Kitchen Sink with Power Cord, GXP50C
0.5 HP at 2,600 RPM
6.34 x 6.34 x 14.76 inches
9.64 pounds
5-year warranty
Pros
- Slim body frees substantial cabinet space
- Light 9.64-pound build is easy to install
- Universal flange fits most existing disposals
- Septic safe with properly sized tanks
Cons
- Internals are galvanized despite the stainless label
- Startup clank before the motor reaches speed
- No jam wrench included and a restrictive drain boot
The Moen Prep Series is the pick when the cabinet is the constraint. At a 6.34 inch diameter and 9.64 pounds it is slim and light, and at 4.6 stars from 2,947 reviews it is one of the best-rated models in the roundup.
The universal flange is the underrated feature. It fits most existing disposals including non-Moen brands, which means a direct replacement is often possible without removing and replacing the sink flange. In a kitchen built in the last ten years, that single detail can be the difference between a one-afternoon job and a plumber’s visit.
It is also the only model in this roundup that the manufacturer describes as septic safe with properly sized tanks, which gives septic households a defensible option instead of guessing. If that describes your home, this is the pick.
The specification deserves a careful read, though. The stainless label applies to the sink collar, while the internal components are galvanized, which is the same corrosion consideration as the Badger. Owners also note a loud clank on initial startup before the motor reaches full speed, and a drain boot that can be more restrictive than typical.
Best for tight cabinets and septic homes
A 2,600 RPM Vortex motor grinds everyday scraps quickly, and the quiet running owners report makes sense at this motor speed. For a couple, a small family, or a kitchen where cabinet space is genuinely scarce, the trade you are making is power you probably will not use for space you will use every day.
For a septic system, the manufacturer’s guidance is the deciding factor. Follow it, and keep greywater and food waste volume modest. Do not assume a 1 HP unit from a general guide is automatically better on a septic system, because higher flow is not always wanted there.
Check what the stainless label covers
Do not assume stainless internals from the material line in the listing. Owners report galvanized components inside a stainless-labelled unit, so treat this like the Badger on longevity and expect a galvanised-parts service life.
Also check for a jam wrench before the first jam, and consider whether the restrictive drain boot will bother you when you rinse a large pan. Neither issue is serious, but both are easier to live with if you know about them.
8. InSinkErator Power 0.75HP – a corrosion fix for Badger owners
InSinkErator Power .75HP, 3/4 HP Garbage Disposal, Power Series EZ Connect Continuous Feed Food Waste Disposer, Black
3/4 HP Dura-Drive motor
2-Stage MultiGrind
Stainless grind parts
6-year service warranty
Pros
- Stainless grind components resist the corrosion that ends Badger units
- 2-Stage MultiGrind resists clogs
- Removable baffle and external dishwasher inlet plug aid cleaning
- Fits existing InSinkErator mounting collars
Cons
- EZ Connect power cord sold separately and proprietary
- Heavier at 17.9 pounds than a Badger 5
- Some owners report a high-pitched whir once fully spun up
If your current unit is a rusted Badger that started leaking from the bottom, this is the direct answer. The grind components are stainless steel rather than galvanized, so the specific failure that forced you into a replacement is the failure this design removes. Owners buy it for exactly that reason, and it fits existing InSinkErator mounting collars so the swap is fast.
Grinding sits a tier above the Badger 5. A 3/4 HP Dura-Drive induction motor with a two-stage MultiGrind system handles vegetable peels, citrus rinds and small chicken bones without clogging, and the reduced-sound design is noticeably smoother than a typical builder-grade unit.
Two design details make daily use easier. The rubber sink baffle is removable for cleaning, and the dishwasher inlet plug is accessible from outside the unit, so you are not contorting under the sink to deal with a connection you may not have.
The weight is the practical warning. At 17.9 pounds it is the second-heaviest model here, and a couple of the reviews mention a high-pitched whistling or whirring sound that appears once the motor is fully spun up. If you are replacing a working unit, the corrosion argument is what justifies this step, not noise.
Best for a rusty Badger replacement
A leak from the bottom of a disposal almost always means the seals have failed, and that is a replacement, not a repair. Plumbing forum advice converges on this point, and it is the single most common reason owners end up shopping in this category. Once you are replacing anyway, paying up for stainless grind parts costs less than buying the same cheap unit twice.
The 6-year service warranty is mid-range, shorter than the Frigidaire and the L-8000 and longer than the Badger. It is a reasonable middle for an upgrade bought for longevity.
Check weight and cord cost
Lift it with two hands, or get help. At 17.9 pounds, this is not a one-person-under-the-sink job in a tight cabinet, and the manufacturer lift and latch mounting is designed to make the connection simple once the unit is in position.
Add the proprietary EZ Connect cord to your install list if you are going plug-in. It is a separate purchase, and owners name it as the single most common complaint about this model.
How to Choose a Garbage Disposal in 2026
A disposal is a cheap appliance attached to an expensive problem. Once you account for a plumber’s visit, a new flange, and a new drain line, the difference between a budget unit and a premium unit is a small share of the total. That is why we would rather see you buy one mid-range unit that suits your cooking volume than two budget models over a decade.
How much horsepower do you actually need?
Horsepower is torque, not speed, and torque decides whether the motor stalls on a hard scrap. Sizing it to your cooking volume is the single most useful thing you can do, because an undersized unit is the leading cause of the complaints in every set of reviews we read.
Use 1/3 HP for one or two people cooking lightly, an apartment, or a rental. Use 1/2 HP for a couple or a small family, which covers most kitchens. Move to 3/4 HP for a family of four or five, or for anyone who cooks most days. Choose 1 HP when you cook heavily, batch meals, or discard bones and pits regularly. Go above that only for near-commercial volume.
Motor type is the second half of the power question. Induction motors such as the Dura-Drive used in the InSinkErator models and the permanent magnet motors used by Waste King, Waste Maid, Frigidaire and Moen both deliver strong grinding, and in practice the difference in your kitchen is far smaller than the difference between a 1/2 HP and a 1 HP motor.
Continuous feed or batch feed?
Continuous feed lets you add food while the motor runs, which is faster and what most kitchens want. Batch feed requires the motor to be off while you load, which is a small safety margin and a common choice in commercial settings. All eight models in this roundup are continuous feed, and for a home kitchen that is the right default.
The safety argument for batch feed is real but narrow. If young children are around the sink while food is being scraped in, continuous feed with a splash guard and a switch you can reach is fine, as long as hands stay out of the drain opening.
How much does noise matter?
Sound comes from two places: the motor and the housing vibrating against the cabinet, and the sink bowl itself ringing as food hits metal. The fix is a sound-insulated shell and a removable sink baffle, which is exactly what the EVOLUTION 0.75HP and the Frigidaire FF13DISPC1 provide.
Do not expect silence. No disposal in any price range is quiet, because a motor spinning a steel impeller at 2,600 RPM makes noise. What you can realistically expect from an insulated model is a low hum you can talk over, versus a rattling you cannot.
Does the power cord come with the unit?
Sometimes, and this is the most common hidden cost in the category. Corded models such as the Badger 5, the Waste King L-8000, the Waste Maid, the L-111, the Moen GXP50C and the Frigidaire include a cord or are corded by design. The InSinkErator EVOLUTION 0.75HP and Power 0.75HP use a proprietary EZ Connect cord that is sold on its own.
Check the included components list before you buy, not the headline. A plug-in install needs an outlet under the sink, and a hardwired install needs a switch on a wall. Deciding this first eliminates the most common install surprise.
How long do garbage disposals last?
A well-made unit that is not overloaded typically runs for many years, and the biggest determinant of lifespan is not the brand, it is whether you feed it things it can grind. Corroded steel components, burned motors and cracked housings are the three common failure modes, and all three trace back to overload, water exposure, or age.
Repair versus replace is a simple rule. A jammed unit that trips its reset button is a repair. A unit that leaks from the bottom, hums without turning, or smells burnt has a failed seal, motor or bearing, and replacement is the only sensible path. Check the warranty first, because in-home coverage can remove the cost question entirely.
What should you never put down a disposal?
The list is short and worth memorising. Never put grease, cooking oil, or fat down the drain, because they congeal in the pipe rather than the disposer. Avoid whole bones, shrimp shells, and oyster shells. Skip fibrous strings such as celery, asparagus, and corn husks, and avoid large fruit pits. Do not put coffee grounds in large amounts, and never put glass, metal, or plastic into the chamber.
Eggshells are the most argued-over item. Some plumbing sources warn that the membrane wraps around the impeller and causes jams, while others point out that ground eggshell acts as useful scouring. Crushed shells in small amounts are fine; whole shells loaded carelessly are a bad bet. The safe answer is to break them up and add them slowly with the water running.
Cold water should run while the disposal works and for a short time after. It carries the slurry into the drain line instead of leaving solids settled in the elbow, which is the other half of preventing clogs.
Do you need a plumber to install it?
Swapping an existing unit is a straightforward job for anyone comfortable with a wrench, and a corded model under an existing outlet needs no electrical work at all. The parts that catch people are flange compatibility, a drain line that does not reach, and hardwiring, which does need an electrician in most jurisdictions.
Call a plumber when you are cutting into existing drain pipe, when the cabinet has no room for the discharge tube, when you need a new switch run, or when the sink flange is cast iron and incompatible.
Frequently Asked Questions
What is the best garbage disposal?
For most homes, the InSinkErator Badger 5 1/2 HP is the best garbage disposal because it pairs a 4.7 owner rating across more than 17000 reviews with a compact body that fits existing InSinkErator hardware, making it the easiest swap in the category. Choose the Waste King L-8000 1 HP instead if you cook heavily or want a 20-year warranty.
Should I get a 1/2 or 3/4 HP garbage disposal?
A 1/2 HP disposer handles a couple or a light-cooking household comfortably, while 3/4 HP is the right call for a family of four or five or anyone who cooks most days. The jump matters because horsepower is torque, and a motor that stalls on ordinary vegetable scraps needs a reset and a hex key. Buy the larger unit if your cooking volume is growing.
What’s the average lifespan of a garbage disposal?
Lifespan depends far more on use than on brand. A unit that is fed grease, large bones and fibrous vegetables will fail early, while a correctly sized motor on ordinary food waste runs for many years. The three common failure modes are corroded steel grinding components, a burned motor from overloading, and cracked housings. All three mean replacement rather than repair.
What should you never put in a garbage disposal?
Never put grease, cooking oil, whole bones, shrimp shells, oyster shells, fibrous strings such as celery and corn husks, large fruit pits, glass, metal or plastic into a disposal. Run cold water while the unit works and briefly afterwards. Eggshells are safe when crushed and added slowly, but whole shells can catch around the impeller.
What is the best continuous feed garbage disposal?
The InSinkErator EVOLUTION 0.75HP is the strongest continuous feed pick in this roundup, combining a 3/4 HP Dura-Drive motor with three-stage MultiGrind and SoundSeal insulation, which owners describe as the quietest running unit they have owned. If maximum grinding power matters more than noise, the Frigidaire FF13DISPC1 at 1.25 HP is the alternative.
Which Garbage Disposal Should You Buy?
Start with your cooking volume, not the brand name. A couple or a light-cooking apartment is best served by the InSinkErator Badger 5 1/2 HP, our editor’s choice, or the Moen GXP50C 0.5 HP if cabinet space is tight. A family of four or five should step up to the InSinkErator EVOLUTION 0.75HP, which is also the quietest unit here and the one we would pick in an open-plan kitchen.
If you cook heavily, discard bones and pits regularly, or simply do not want to think about this appliance again, the Waste King L-8000 1 HP pairs stainless grinding components with a 20-year warranty, and the Frigidaire FF13DISPC1 1.25 HP takes that further with the most power and a 12-year warranty. Tight budgets have a real answer too: the Waste Maid 1/2 HP is quiet, compact and backed for eight years.
Whichever of these best garbage disposals you choose, measure your cabinet clearance, confirm whether a power cord is included, and check your sink flange material before the box arrives. Those three checks prevent nearly every install problem we found in owner reviews.
