The InSinkErator Badger 5 is the best continuous feed garbage disposal for most kitchens, because it pairs a 1/2 hp Dura-Drive induction motor with a compact body that drops into the hardware most homes already have. We went through twelve continuous feed models from seven brands, read the technical sheets, and sorted through thousands of owner reviews to find the ones that actually earn a place under your sink. Last updated October 2026.
What separates the good continuous feed disposals from the disappointing ones rarely comes down to horsepower. It comes down to whether the power cord is in the box, whether the mounting ring will accept your existing sink hardware, whether the grind components are stainless or galvanized, and how long the warranty runs. Those four details decide whether a swap is a twenty-minute job with a screwdriver or a plumber’s afternoon.
If you want the wider picture rather than continuous feed only, our general best garbage disposal roundup covers batch feed models too. This list stays narrow on purpose, because continuous feed is the format most kitchens are searching for and the one where the fit-and-finish details matter most.

1. InSinkErator Badger 5: Best Overall Continuous Feed Disposal
InSinkErator Badger 5 Garbage Disposal, Badger Series 1/2 HP Continuous Feed Food Waste Disposer
- Drops into existing InSinkErator hardware
- Compact 11.5 in body frees cabinet space
- Quiet for a 1/2 hp motor
- Allen wrench jam port included
- 20K+ owners rate it highly
- No power cord in the box
- Instructions vague on unit orientation
- Dishwasher knockout plug must be removed
The Badger 5 is the default pick for a reason, and after reading through owner feedback it is easy to see why. It is a 1/2 hp Dura-Drive induction motor in a 6.31 inch wide body that stands 11.5 inches tall, weighing 13.79 pounds, and the Quick Lock sink mount means it will usually hang on the ring already under your sink.
That induction motor is the quiet part of the story. Permanent magnet motors spin faster and are common on budget disposals, while an induction motor delivers its torque lower and slower, which is a large part of why owners describe this as unusually quiet for its class.
The repeated friction in reviews is electrical rather than mechanical. This disposal does not include a power cord, so if you are replacing a unit that had one you can reuse it, and if you are starting from scratch you need a cord kit or an electrician. Several owners also flagged that the printed instructions do not make it obvious which way the unit should face relative to the drain.
One more trap worth naming: if a dishwasher drains through the disposal, the dishwasher inlet knockout plug has to be removed. Miss it and the dishwasher holds standing water after every cycle, which reads as a dishwasher fault and is not one.
Why the Badger 5 suits a typical kitchen
At 1/2 hp it handles peels, coffee grounds, small vegetable scraps and small bones without drama, which covers the majority of what a two to four person household throws at a sink. It is the unit most plumbers reach for when someone wants a known quantity of motor without a large motor footprint.
Where it falls short
Heavy cooks who process fibrous stalks or frequent bones will outgrow a 1/2 hp chamber, and the 2-year in-home warranty is the shortest cover on any InSinkErator model in this list. Anyone replacing a failed unit with no existing cord should look at the GE GFC525N instead, because the cord and install kit come in the box.
2. Waste King L-2600: Best Continuous Feed Disposal With a Cord in the Box
Moen L-2600 Waste King 1/2 HP Continuous Feed Garbage Disposal with Power Cord
- Pre-installed 36 inch power cord saves an electrician
- Stainless grind ring resists corrosion
- Removable rubber splash guard
- Lights at 7.8 pounds for easy handling
- No Allen wrench jam-release socket
- Cord is awkward to remove for hardwiring
- Plumbers putty not included
The L-2600 is the answer for anyone who wants continuous feed convenience without touching electrical work. A 36 inch power cord is pre-installed, so it plugs into a wall switch and runs, which is exactly what a renter or a first-time installer needs.
It uses a 2,600 RPM permanent magnet motor and an EZ Mount bayonet-style system rather than the three-screw arrangement most disposals use. Owners report removing and reinstalling the whole unit in under ten minutes with basic tools, and the stainless steel grind ring is a real step up from the galvanized rings on the InSinkErator Badger models.
The removable rubber splash guard is the sleeper feature. Lift it out and you can clean the sink bowl without fishing food down the throat, and reviewers single it out as the reason they stopped scraping scraps off the disposal rim.
Weight matters here too. At 7.8 pounds this is the lightest disposal we covered, which matters a lot when you are holding a unit upside down under a cabinet with a water line and two supply lines in the way.
Best for a rental or a no-rewire install
If there is no existing cord and no easy outlet, this removes the single most common reason a DIY swap turns into a service call. The five-year warranty is also more generous than the two years on the Badger 5.
Watch out for the cord and the jam port
Two gaps stand out. There is no under-sink Allen wrench access port like InSinkErator units carry, so clearing a jam means working from above. And the attached cord is difficult to remove if you later decide to hardwire, which is the opposite trade-off from a disposal with no cord at all.
3. Waste Maid 1/2 HP Anti-Jam: Best Budget Continuous Feed Disposal
- Longest warranty in the 1/2 hp group
- Flange stopper cord and splash guard included
- Balanced turntable reduces vibration
- Compact 5.2 inch footprint
- No under-sink jam-release crank
- Light duty for large carcasses and fibrous items
- Only 1/2 HP available in this range
The Waste Maid 1/2 HP is the one that keeps surprising people, because a 4.6 average across more than six thousand reviews is not what you expect from the entry of this category. The build is stainless steel throughout rather than a painted housing, and the box includes a chrome sink flange, stopper, power cord and removable splash guard.
Grinding comes from a 1/2 hp 2,600 RPM permanent magnet motor paired with a Torque Master anti-jam stainless grinding system. A balanced turntable and impellers cut vibration, and owners report that the sink does not rattle the way lighter chassis can.
At 5.2 inches wide and 12.9 inches tall this is one of the most compact bodies here, which is why it turns up in apartment kitchens where cabinet space is already spoken for by a water filter.
Mounting is a standard 3-bolt arrangement, so it replaces most three-bolt disposals without adapters. That is the broadest compatibility of the group, just short of a brand-specific bayonet system.
Where the value shows up
An 8-year warranty plus a lifetime corrosion warranty is a better paper promise than anything else at this horsepower, and the included flange, stopper and cord mean one box covers the whole install for most sinks. If your budget is fixed, this is the model that gives you the most on paper.
Where it will not keep up
There is no manual crank or notch for clearing a jam, which owners call a non-issue right up until the first jam. And 1/2 hp is genuinely light duty for a household that grinds bones, corn cobs or large fibrous pieces every day.
4. InSinkErator Badger 5XP: Best Value Upgrade to 3/4 HP
InSinkErator Badger 5XP Garbage Disposal, Badger Series 3/4 HP Continuous Feed Food Waste Disposer
- Step up to 3/4 hp without changing brands
- Drop-in fit with existing InSinkErator mounts
- Compact body saves cabinet space
- Induction motor runs smooth and steady
- Heaviest of the Badger models at 15.23 pounds
- No power cord included
- Warranty is shorter than rival 3/4 HP models
The Badger 5XP exists because a lot of households want more motor than half horsepower without wanting to learn a new mounting system. It is the step-up InSinkErator, using a 3/4 hp Dura-Drive induction motor with galvanized steel grind components, and it drops into the same compact footprint as the smaller Badger models.
Owners consistently describe it as the choice for tougher scraps than the 1/2 HP Badger can take, while keeping the fit they already have. Reddit buyers replacing a failed unit point to this model again and again as the like-for-like upgrade.
At 15.23 pounds it is the heaviest of the Badger line, so plan the lift before you unbolt the old one. Two people under a sink is not a bad idea, particularly if the unit has to be rotated into position under a fixed drain.
The 4-year in-home full service warranty is the one place this model lags. Several 3/4 HP competitors in this roundup carry eight or ten years, so on paper the 5XP gives up cover for compatibility.
Best when you already own InSinkErator hardware
If the unit you are replacing is an InSinkErator, this is the shortest path to more grinding power. No adapter ring, no new flange, and the same wall switch wiring if you are reusing a cord.
Where the value argument weakens
Buyers who are not tied to the InSinkErator mount get more for the same money elsewhere. A corded 3/4 HP model with stainless grind components and an eight or ten year warranty is the alternative worth comparing before you commit.
5. InSinkErator Badger 1: Best Continuous Feed Disposal for Tight Under-Sink Spaces
InSinkErator Badger 1 Garbage Disposal, Badger Series 1/3 HP Continuous Feed Food Waste Disposer
- Short body at 11.38 inches
- Lightweight and easy to position
- Quieter than most 1/3 hp machines
- Direct Badger series replacement
- 1/3 hp struggles with tough food waste
- No power cord included
- Only a 1-year parts and service warranty
The Badger 1 is among the smallest continuous feed disposals in this list, at 11.38 inches tall and 6.31 inches across. If your cabinet has a low shelf, a deep bowl trap, or a dishwasher hose crossing the space, that height difference is the whole reason to choose it.
Power comes from a 1/3 hp Dura-Drive induction motor with galvanized steel grind components and a 30 cfm flow rate. Owners describe it as quiet, unobtrusive and perfectly adequate for peels, leftovers and small bones in a one or two person home.
Installs are routinely reported at 30 to 60 minutes for a competent DIYer, mostly because the body is light enough to hold in one hand while you work the mounting bolts with the other.
The listing is specific that it comes without a power cord, and the warranty is a full 1-year parts and in-home service cover, the shortest in this roundup. It is also listed as 120 V, which matters only if you are outside the United States.
Best for a small kitchen or a small household
Low cooking volume plus tight cabinet space is exactly the situation half horsepower wastes money on. This machine does the same daily work as the Badger 5 while giving back several inches of clearance.
Where it stops coping
Light duty means light duty. Fibrous vegetables and hard scraps will stall the impellers sooner than on a 1/2 HP model, and the one-year warranty offers no protection if a seam starts weeping after year two.
6. Waste King L-3200: Best 3/4 HP Corded Disposal With Stainless Components
- All stainless grind components resist corrosion
- Eight year warranty is unusual at this power
- Cord included so no electrical work
- Sound insulated 2700 RPM motor
- Bundled splash guard is stiff and restrictive
- Bulky upper housing can clash with water lines
- Cord resists removal if you hardwire
The L-3200 is the model to look at if you want 3/4 HP without giving up stainless grind components or a long warranty. It runs a sound insulated 2,700 RPM permanent magnet motor, and the grind chamber is all stainless steel rather than galvanized, which is the difference that shows up after a decade of hard water.
Installation is an EZ Mount system with a removable splash guard and a pre-installed power cord. At 10.8 pounds for the body, owners note it is light enough to hold while you align the mount, which is the part that usually needs three hands.
The recurring negative cluster is installation hardware rather than performance. Reviews mention a stiff splash guard that is hard to push food past, an oversized cushion mount that occasionally resists seating on the flange, and a water line conflict caused by the wider upper housing.
On the plus side, owners report a clean bill of health after a year or more of daily use, and the eight-year limited warranty is longer than almost anything else at this horsepower.
Best for hard water and long service life
Stainless grind rings and shredders resist the corrosion that eventually turns a galvanized ring into a leak source, and this is the model in the 3/4 HP class that pairs that material with an eight-year warranty. For a family grinding daily, that combination is the reason to choose it.
Where installation gets in the way
Measure before you buy. At 7.75 inches in diameter and 13.62 inches long this is a wider body than the Badger models, and under-sink cabinets with a tight turn on the cold water line are where the fit complaints come from.
7. Moen Prep Series PRO GXP50C: Best Compact Continuous Feed Disposal
Moen Prep Series PRO Continuous Feed Compact Garbage Disposal for Kitchen Sink with Power Cord, GXP50C
- Lightweight build is easy to lift and install
- Vortex motor grinds fast with few jams
- Power cord included for a true drop-in swap
- Septic safe on qualifying tanks
- Compact bowl limits batch size per cycle
- Half horsepower is light duty
- Warranty is short against other Moen models
The GXP50C is built around a 2,600 RPM Vortex motor in a body that is 6.34 inches across, 14.76 inches tall and only 9.64 pounds. It is a light 9.64 pound build that is easy to lift into place and position under the cabinet on your own.
It is a genuine drop-in replacement rather than a brand-locked install. The pre-installed power cord means no electrical work, and the box includes a drain elbow, mounting assembly, stopper, sink flange and cord, so most installs need nothing else.
Moen rates it septic safe when used with a properly sized tank, which is worth knowing if you are on a rural system. That claim depends entirely on tank condition and maintenance, not on the disposal label.
Buyer sentiment lands on adequate rather than exceptional. The compact chamber means you grind in smaller increments, and the five-year warranty is noticeably shorter than the eight and ten year covers on other Moen disposals.
Best for quick installs over an existing drain
The combination of a supplied flange, mounting assembly and cord means one box handles a first-time install in a kitchen that has never had a disposal. That is a rarer scenario than it sounds in older homes where the previous unit was removed years ago.
Where capacity becomes the limit
Small bowl, small chamber, small appetite. If you batch a whole dinner’s prep into the sink before switching on, a larger chamber will serve you better, and the 1/2 HP motor will not chase a heavy load.
8. GE Disposall GFC525N: Best Complete Kit for a Corded Install
- Install kit and power cord both in the box
- Anti-clog drain fin directs water at an angle
- Advanced sound reduction for open plans
- 7-year warranty at this tier
- Half horsepower caps heavy cooking households
- Lower review volume than InSinkErator and Moen
The GFC525N solves the problem that annoys people most, which is the missing cord. GE includes the power cord and a full EZ Mount install kit, so a replacement in a kitchen with no existing wiring is a single-box job rather than a parts hunt.
Underneath it is a 1/2 hp motor that spins past 2,600 RPM, with anti-rust stainless steel blades designed to hold their edge longer than coated alternatives, and anti-clog drain fin technology that angles water at the drain to help carry particles away.
It is also one of the smaller bodies here, at 5.19 by 5.5 by 12.69 inches and 8 pounds, with GE listing advanced sound reduction as a design goal. Owners in open-plan kitchens mention it specifically as a quiet change from an older unit.
The 7-year replacement warranty is generous for the segment. The limitation is horsepower, since GE rates this one for two to four person homes, and it is sized for cooked meat, beans and seeds rather than bone-heavy cooking.
Best when nothing is wired and nothing is reusable
Rental, first home, or a kitchen where the old cord was pulled out years ago. Everything you need is in the box, which removes the most common reason people hire an electrician for a disposal swap.
Where it is not the answer
If your household grinds bones, pits or corn cobs daily, half horsepower is the ceiling no matter how good the blades are. Compare it against the 3/4 HP corded models before you settle, and expect a longer install if your old mount is a different pattern.
9. KitchenAid KCDB250G: Best Direct Replacement for an Older KitchenAid
Kitchen Aid (84211643) KCDB250G 1/2 HP Continuous Feed Garbage Disposal
- Near drop-in fit for older KitchenAid mounts
- Sound cover reduces noise versus the old model
- Stainless steel construction
- Power cord and strain relief not included
- Attachment ring is poorly illustrated in the directions
- Louder than the insulated models in this roundup
The KitchenAid KCDB250G is a replacement story more than a shopping story. Most owners are swapping out a decades-old KitchenAid disposal with the same half horsepower model, reusing the existing mount and cord, and rating the result as close to drop-in.
Specs are modest by design: a 1/2 hp motor at 1,725 rpm, a stainless steel body measuring 11.375 inches tall by 6.625 inches wide, and a sound-insulating cover that owners say does reduce noise against the unit it replaces.
The recurring accessory gaps are real. The power cord and cord grip strain relief are not included, and the installation directions do not clearly illustrate the attachment ring, which is exactly the part you need to see for a clean install.
Packaging condition is also a minor complaint, with owners reporting dents from the retail shelf box. Check the corners on arrival before you start, because a dented housing is a leak risk later.
Best for a like-for-like swap
If the unit dying under your sink is an older KitchenAid of the same size, this is the shortest job on the list. Reuse the mount, reuse the cord, and the drain connection stays as it is.
Where it is the wrong pick
The 1,725 rpm figure is the slowest in this roundup, and the disposal is louder than the sound-deadened models here. If you are not replacing a KitchenAid specifically, a 2,600 to 2,800 RPM motor will feel noticeably better on fibrous scraps.
10. Whirlpool GC2000XE: Best Match for Older Whirlpool and Matag Mounts
- Exact size match for older Whirlpool and Matag mounts
- 25 to 30 minute swap reusing the old cord
- Low power draw and quiet
- Manual reset protector is simple to service
- Power cord and connector clamp not included
- Galvanized rather than stainless components
- Professional plumbing often needed
The GC2000XE exists for one job, and it does that job extremely well. If the disposal you are removing is an older Whirlpool or a compatible Matag unit, the dimensions are close enough that the existing drain pipes still line up and the install becomes a half-hour swap.
It is a 1/2 hp continuous feed machine with a stainless steel sink flange, a one-piece plastic stopper, a galvanized steel grinding wheel and shredder ring, and an overload protector with a manual reset that owners describe as straightforward to service.
Reusing the original power cord and sink drain is what keeps installs inside 30 minutes, and buyers report repeat purchases after ten to twelve years of service, which is a reasonable expectation for a machine of this type.
Be realistic about the electrical side. The power cord and connector clamp are not included, and owners frequently mention hiring a plumber and occasionally an electrician, especially where the old cord is brittle or the outlet is undersized.
Best for a like-for-like Whirlpool replacement
Nobody should pay to redo drain plumbing when a matching body exists. If your old unit is a Whirlpool of this generation, the geometry, flange and drain all line up and the savings are immediate.
Where it falls behind the field
Galvanized grind components are the main compromise, and on hard water that is the part that eventually fails. The 1/2 HP motor also has no headroom for bone-heavy cooking, so heavy households should step up rather than work around it.
11. Moen Chef Series GX100C: Best for Large Families and Heavy Cooking
Moen GX100C Chef Series 1 HP Continuous Feed Garbage Disposal with Sound Reduction, Disposer Power Cord Included
- Full 1 hp motor chews through the toughest scraps
- SoundSHIELD insulation tames a big motor
- Cord included and fits most existing assemblies
- 10-year warranty is among the longest here
- Tallest body in the list at 16 inches and a hefty 13 pounds
- Costs the most of the twelve
- Overpowered for small kitchens
The GX100C is the heavy cooking pick. A 1 hp Vortex motor spinning at 2,800 RPM has the torque headroom to take fibrous stalks, small bones and larger scraps that stall a half horsepower machine, and reviewers describe jams as rare rather than absent.
What makes it interesting is the noise treatment. SoundSHIELD sound-deadening insulation is fitted specifically to keep a one horsepower motor tolerable, which is the usual objection to buying this much power in the first place.
Installation is the easier half of the story. Moen states it fits most existing assemblies including other brands, and the disposer power cord is pre-installed, so a first-time install does not need an electrician.
The 10-year limited warranty with in-home service is one of the longest covers in this roundup, and the unit is listed as septic safe when the tank is properly sized.
Best for a family that actually cooks
Four or more people cooking most nights, or one person who grinds bones, pits and corn cobs routinely. This is the machine that stops you thinking about what the disposal can handle and lets you cook normally.
Where it is more machine than you need
At 16 inches tall and 13 pounds it is the tallest body in this roundup, so measure the cabinet before you commit. It also carries the highest cost of the twelve, and in a small kitchen a well-built 3/4 HP model will deliver nearly all of the benefit for far less money and far less space.
12. GE Disposall GFC720N: Best Corded-Ready 3/4 HP With a Large Chamber
- 32 ounce grind chamber
- larger than the other units listed
- Reaches full speed fast for a fine grind
- Includes 3-bolt adapter and flange kits
- 10-year replacement warranty
- Non-corded version needs electrical work
- Lowest average rating in the group
- Fewer customer reviews than the others
The GFC720N is chosen for two reasons: a 32 ounce grind chamber, larger than any other capacity figure in the spec sheets we reviewed, and a 3/4 hp motor that passes 2,700 RPM. That combination means you can put a real quantity of peelings and small bones in at once and still get a fine grind.
The box includes a 3-bolt easy-mount adapter kit and a sink flange kit, so replacing a standard three-bolt unit is straightforward. The anti-jam design is intended to push more of the waste down the drain instead of wrapping it around the impeller.
This is the non-corded version, which means it is built to be hardwired. In a kitchen that is being renovated and already has an electrician on site that is a sensible choice, and the 10-year replacement warranty is among the longest available.
In a kitchen with no existing wiring it is the wrong pick, because an outlet has to be added first. It also carries the lowest average rating in this group at 4.3 stars, on the thinnest review base at 270 reviews, so treat the number as less predictive than the others here.
Best for batch prep and permanent installations
Cooking for a crowd on a weekend, or a kitchen where a new disposal is being hardwired as part of a remodel. The large chamber means fewer switch cycles and less standing water in the bowl.
Where the rating reflects real friction
Installation is the problem, not the grinding. Non-corded means an electrician, and a thinner user base means fewer of the small fit problems that come with a design that has been in the wild for a decade are already solved.
How to Choose a Continuous Feed Disposal
We read the technical sheets and the owner feedback for all twelve, and the same pattern kept surfacing.
Horsepower is the first question and the least interesting one. A 1/3 HP handles peels, coffee grounds and small scraps for one or two people. A 1/2 HP covers a two to four person household, which is where most homes sit. A 3/4 HP is for frequent meat and bone scraps or a family of four or five, and 1 HP is for heavy cooking and large households.
More horsepower is not automatically better. A larger motor draws more current, needs more under-sink clearance, and makes more noise unless it is properly insulated, and Consumer Reports testing has previously shown that high price alone does not guarantee strong performance. Buy the smallest motor that handles your real cooking load.
Motor type matters more than most buyers realise. Induction motors, used across the InSinkErator range, deliver torque at lower speeds and run noticeably quieter. Permanent magnet motors spin faster, typically between 2,600 and 2,800 RPM, and grind finer but louder.
The cord question saves real money and frustration. Roughly half the disposals in this roundup arrive with a pre-installed power cord and half do not. If you are replacing a unit that still has a working cord, a cordless model is fine. If nothing is wired, buy a corded one and skip the electrician.
Material is the difference you will feel in year ten. Stainless steel grind components resist corrosion, and galvanized rings eventually weep from the inside out. On hard water, stainless is worth paying for; the Waste King L-3200 and the GE GFC525N both pair it with a long warranty.
Warranty length is the least glamorous and most useful signal. A 1-year cover on a disposal is thin, and several units in this list run eight to ten years with in-home service. Longer cover usually tracks better sealing and heavier components, though it is not a guarantee.
For a broader look at noise, our quiet garbage disposal roundup covers sound treatment in more depth. For general guidance across all formats, see our best garbage disposal picks.
Expected service life is around 12 years for a typical unit. You can stretch that considerably by running cold water during and after every use, avoiding fibrous and starchy loads, and treating a jam early rather than forcing the motor.
Mounts, Switches and Electrical Setup
Most disposals hang from a three-bolt mounting assembly that stays on the sink when you swap the motor unit. That is why a like-for-like replacement is fast and a brand change is not. The Badger models use a Quick Lock sink mount, the Waste King, Moen and GE models use an EZ Mount style bayonet or quick-release system, and the standard three-bolt arrangement is the fallback that fits the widest range of older units.
If you are changing brands, budget for the possibility that the existing flange or mounting ring will not seat correctly. Several units in this roundup include a three-bolt adapter, so a brand change is not a plumbing job.
Continuous feed needs a control. A wall switch beside the sink is the standard, and a replacement with a pre-installed cord usually plugs into the existing switch box. If you have no switch, or you are in a rental where drilling into a wall is not allowed, an air switch mounted on the sink deck or countertop is the alternative and costs far less than running new electrical work.
If a dishwasher drains through the disposal, remove the dishwasher inlet knockout plug from the disposal’s side inlet. It is there to stop water escaping when the dishwasher is not connected, and leaving it in means standing water in the dishwasher after every cycle.
What Not to Put Down a Continuous Feed Disposal
The defining risk of a continuous feed unit is that the opening stays live while the motor runs. Plumbers writing in forum discussions about disposals are blunt about the food side, and about the physical side too. Keep hands, utensils and fingers out of the throat while the unit is running, and only ever use the reset button or a hex wrench with the power off at the wall switch.
Whole large bones, pork chops and similar dense cuts are the food that generates service calls. They do not grind, they wedge, and they can bend an impeller. Break them down or put them in the bin.
Fibrous and stringy material is the other repeat offender. Celery stalks, corn cobs, artichoke cores, asparagus ends and onion skins wrap around the impeller rather than cutting. Starchy foods such as potato peels and large amounts of pasta build a paste in the chamber that eventually blocks the drain.
Also keep out of the sink: grease and cooking oil, which congeal in the trap, and non-food items including cigarette butts, paper towel, dish rag and packaging. A magnet ring in the bowl catches cutlery before it reaches the blades, and it is worth installing if the disposal you own does not have one.
Frequently Asked Questions
Is continuous feed garbage disposal better?
A continuous feed disposal is better for most kitchens because you can grind scraps as you cook instead of one batch at a time, and it is the most common type with the widest range of horsepower. A batch feed disposal is quieter and safer where small children are involved, because it only runs while a stopper covers the opening.
Should I get a 1/2 or 3/4 HP garbage disposal?
A 1/2 HP model suits a two to four person household doing routine cooking. Step up to 3/4 HP if you regularly grind small bones, corn cobs or fibrous vegetables, or if five or more people use the kitchen. More horsepower is not automatically better, because a larger motor draws more current, needs more clearance and is louder unless it is insulated.
Do continuous feed garbage disposals come with a cord?
It varies. In this roundup the InSinkErator Badger 5, Badger 5XP, Badger 1, KitchenAid KCDB250G and Whirlpool GC2000XE arrive without a power cord, while the Waste King L-2600 and L-3200, Moen GXP50C and GX100C, Waste Maid 1/2 HP and GE GFC525N include one. The GE GFC720N is a non-corded hardwired model.
Will a new garbage disposal fit my old mount?
Usually, if you stay with the same mounting style. A three-bolt mount is the most universal and replaces most older three-bolt disposals, while InSinkErator Quick Lock and the EZ Mount systems on Waste King, Moen and GE models are brand-specific. If you change brands, check that the existing flange and mounting ring will seat before you order.
How many years do garbage disposals last?
A typical garbage disposal lasts around 12 years. Lifespan is extended by running cold water during and after every use, keeping grease, large bones and fibrous vegetables out of the chamber, and fixing a jam early rather than forcing the motor. Stainless steel grind components generally outlast galvanized ones in hard water areas.
Does a dishwasher need an air gap if you have a garbage disposal?
When a dishwasher drains through the disposal, you must remove the dishwasher inlet knockout plug from the disposal side inlet, otherwise the dishwasher holds standing water after every cycle. An air gap is a separate plumbing fixture and is a local code question rather than a disposal feature, so check your local requirements.
The Bottom Line on Continuous Feed Disposals
The InSinkErator Badger 5 is the best continuous feed garbage disposal for most kitchens, because it drops into the hardware most homes already have, runs quietly for its class, and costs little in cabinet space. Pick the Waste King L-2600 if you need a cord in the box, the Waste King L-3200 if you want 3/4 HP with stainless grind components, and the Moen GX100C if your household grinds heavy loads daily.
Check the cord, check the mount, and check the warranty before you buy. Those three details decide whether the install takes twenty minutes or most of a weekend.
