Call (310) 845-6027Talk to a Plumber NowShould you repair it or replace it?
This is the first question worth answering, because it changes what you spend. A disposal that is eight years old with a jam is worth clearing. The same unit leaking from its body is not worth touching.
Usually worth repairing
- It hums but will not turn. Something is jammed against the impellers. The motor is fine.
- Nothing happens at all. Often just the reset button, a tripped breaker, or a failed wall switch.
- It drains slowly. Usually a clog in the trap or branch line downstream, not the disposal itself.
- It leaks at a connection. The sink flange, dishwasher hose, or discharge tube can all be resealed or replaced.
Usually worth replacing
- It leaks from the body of the unit. That is an internal seal failure. There is no economical repair — the water is running through the motor housing.
- It trips the reset constantly even on light loads. The motor is failing.
- It has gone quiet-then-dead repeatedly. Windings are on the way out.
- It is past ten to twelve years old and giving you trouble. Most residential units are built for roughly that.
We will tell you honestly which side of that line you are on. If your unit is worth saving, we would rather clear it and keep you as a customer than sell you a disposal you did not need. Call (310) 845-6027 for a Straight Answer
Choosing the right garbage disposal
Four things actually matter. Everything else is marketing.
1. Horsepower
This is the single biggest driver of whether the unit handles your kitchen or fights you.
| Motor | Best for | Notes |
|---|---|---|
| 1/3 HP | One or two people, light cooking | Cheapest, but jams easily. We rarely recommend it. |
| 1/2 HP | Small households, apartments, condos | The realistic entry point for most LA kitchens. |
| 3/4 HP | Families, regular cooking | The sweet spot. Handles fibrous scraps and small bones without complaint. |
| 1 HP+ | Heavy cooking, large households | Quietest under load, longest lived, most expensive. |
2. Continuous feed or batch feed
Continuous feed runs while you push waste in. It is what most homes have and what most people expect.
Batch feed only runs once you seat a stopper in the drain. It is slower, but nothing can fall into a running disposal — worth considering with small children in the house.
3. Motor type
Induction motors turn slower, around 1,725 RPM, but deliver high torque and are less prone to jamming. Permanent magnet motors spin much faster, in the 2,500–2,800 RPM range, and are lighter and cheaper, but with less grunt at the moment of impact. Neither is simply better — it is a trade between torque and cost.
4. Grind chamber and sound insulation
Premium units use stainless steel grind components and a stainless chamber, wrapped in sound insulation. Budget units use stainless grind components in a polymer chamber, which is lighter and will not corrode but transmits far more noise. If your kitchen is open to a living area, insulation is the upgrade you will actually notice every day.
On septic: some hillside and canyon properties around Los Angeles are on septic rather than sewer. A disposal sends a lot of additional solids to the tank, which means more frequent pumping and a tank sized to cope. Tell us if you are on septic and we will talk through whether a disposal makes sense at all.
Garbage disposal brands compared
We install whatever you want, and we will happily install a unit you bought yourself. Here is our honest read on the major brands. Prices below are approximate street prices for the unit only and move around constantly — treat them as a rough anchor, not a quote.
InSinkErator
Roughly $100 (Badger) to $500+ (Evolution)Induction motor with high torque — less likely to jam on tough loads
Evolution series uses stainless grind components and a stainless chamber
Genuinely the quietest units on the market thanks to real sound insulation
The most common brand in LA homes, so parts and replacements are easy
You pay a premium for the name and the insulation
Entry-level Badger models are basic — the reputation comes from Evolution, not Badger
Heavier units, 17–20+ lbs, which matters in a tight cabinet
Waste King
Roughly $80 to $250Typically 30–50% cheaper than InSinkErator at comparable horsepower
Permanent magnet motor spins fast and clears soft waste quickly
Ships with a power cord already attached, which saves time and cost on install
Lighter, with a corrosion-proof polymer chamber
Noticeably louder — less insulation and a higher-RPM motor
Polymer chamber is not as robust as full stainless
Less torque, so it can bog down where an induction motor would grind through
Moen
Roughly $110 to $350GX series is genuinely compact — the one we reach for when cabinet space is tight
Host series uses a permanent magnet motor tuned for more torque
Good middle ground on price, noise, and build
Range concentrates on 1/2 and 3/4 HP — fewer heavy-duty options
Less common in older LA housing stock than InSinkErator
KitchenAid
Roughly $150 to $400Offers both continuous and batch feed — one of the better batch feed options if you want that safety
Solid build quality at the mid-to-high end, mostly 3/4 HP with some 1 HP units
Priced at a premium without always matching InSinkErator on noise
Narrower model range, so fewer choices if you have an unusual constraint
GE and other budget brands
Roughly $63 to $180Cheapest way to get a working disposal in place
Fine for a rental, a flip, or light use
Mostly 1/3 to 1/2 HP — underpowered for a busy kitchen
Shorter warranties and more basic internals
Loud, and typically the first thing to fail in a remodel we get called back to
If you want the short version: for most Los Angeles homes we would put a 3/4 HP insulated unit under the sink and not think about it again for a decade. If budget is the constraint, a 1/2 HP Waste King does the job for less and you accept the noise. Ask Us What Fits Your Kitchen
What garbage disposal installation actually involves
A straightforward swap takes us about an hour. Here is what happens:
- Power off and disconnect. Breaker off, then we disconnect the trap, the dishwasher drain hose, and the electrical.
- Remove the old unit and mount. The mounting assembly at the sink flange comes out too if we are changing brands or the old one is corroded.
- Set the new sink flange. Sealed properly with plumber’s putty. This is where most DIY installs eventually leak.
- Hang the unit and reconnect. Discharge tube to the trap, dishwasher hose to the inlet, electrical made up. New units need the dishwasher knockout plug removed — forgetting it is the single most common install mistake and it backs the dishwasher up.
- Test under load. We run water and waste through it and check every joint for weeping before we leave.
Things that make an LA install less straightforward
Older homes across Los Angeles — and there are a lot of them — throw up a few recurring complications. Cast iron or galvanized drain lines that are corroded at the connection point and need a section replaced. Drain arms sitting at the wrong height for the new unit’s discharge. No dedicated switch or outlet under the sink, which means an electrical addition. Cabinets too shallow for a full-size premium unit. We check all of it before quoting, so the price we give you is the price you pay.

Call (310) 845-6027Common garbage disposal problems, and what they mean
It hums but does not spin
The motor has power but the impeller plate is jammed. There is a hex socket on the underside of most units for freeing it manually. Do not leave it humming — you will burn the motor out in minutes. Switch it off at the wall and call us.
Completely dead, no sound
Start with the red reset button on the bottom of the unit. If that does nothing, check the breaker. If both are fine, it is the switch, the wiring, or the motor.
Water under the cabinet
Where it leaks from tells you everything. Top, at the sink flange: the seal has failed and can be redone. Side, where the hoses connect: usually a loose or perished connection. Bottom, from the body of the unit itself: the internal seal is gone and the disposal needs replacing.
Suddenly much louder, or rattling
Something hard is loose in the chamber — a bone fragment, a bottle cap, a piece of cutlery. If it is empty and still rattling, a mounting bolt or the impeller itself has come loose.
Drains slowly, or backs up into the other sink
The disposal is usually innocent here. The clog is downstream in the trap or the branch line. If it is backing up into a second basin or the dishwasher, the blockage is past the tee. See drain cleaning in Los Angeles.
Smells, even after running it
Grease and film on the chamber walls and the underside of the splash guard. Ice cubes and cold water scour the chamber; the splash guard needs scrubbing by hand. If the smell persists, there is standing waste further down the line.
What not to put down a garbage disposal
A disposal is not a bin. Most of the jams and clogs we get called out for in Los Angeles come down to the same handful of things:
| Never | Why |
|---|---|
| Cooking grease, oil, bacon fat | Liquid going in, solid inside your pipe twenty feet down. The single most common cause of kitchen line blockages we clear. |
| Coffee grounds | They do not break down. They pack into a dense sludge in the trap. |
| Eggshells | The membrane wraps around the impellers; the shell grinds to sand that settles in the trap. |
| Pasta, rice, oatmeal | Keeps swelling after it is down there. |
| Fibrous vegetables | Celery, artichoke, corn husks, onion skins. The strings wrap the impellers rather than cutting. |
| Bones and fruit pits | Small soft bones are fine on a 3/4 HP unit. Beef bones, peach pits and avocado stones are not. |
| Anything non-food | Twist ties, produce stickers, bottle caps, cutlery. Obvious, and it still happens weekly. |
The habit that prevents most call-outs: run cold water before, during, and for fifteen seconds after. Cold keeps grease solid so it gets ground and flushed rather than coating the pipe. Hot water melts it so it travels further and sets somewhere worse.
Frequently asked questions
How long does a garbage disposal installation take?
A like-for-like replacement is usually under an hour. Add time if the mounting assembly has to change, the drain arm needs reworking, or there is no existing switch and outlet.
Can I supply my own disposal?
Yes. Plenty of our customers buy the unit themselves and have us fit it. We will tell you before you buy whether it will fit your cabinet and drain configuration.
How long should a garbage disposal last?
Ten to twelve years is a fair expectation for a decent unit in a normal household. Cheap units in heavy use can be half that. Hard use with grease and fibrous waste shortens it considerably.
Do I need a plumber, or is this a DIY job?
Mechanically it is within reach for a confident DIYer. The two things that go wrong are the flange seal, which leaks slowly and rots the cabinet base before you notice, and the dishwasher knockout plug, which backs the dishwasher up. If there is electrical work involved, get a professional.
Which garbage disposal is quietest?
Insulated stainless-chamber units with induction motors, InSinkErator’s Evolution line being the reference point. If your kitchen opens onto a living space, it is worth the difference.
Do you install garbage disposals across Los Angeles?
Yes — the Westside, Beverly Hills, Culver City, Santa Monica, Silver Lake, Hollywood and the surrounding neighborhoods. Our shop is on Beethoven Street in Los Angeles.

Call (310) 845-6027Book OnlineGarbage Disposal Installation: Common Questions
What horsepower do I actually need?
For one or two people who mostly rinse plates, 1/3 or 1/2 horsepower is enough. A household that cooks daily does better with 3/4 horsepower, which carries more torque and jams less on fibrous scraps. One horsepower suits large families and heavy vegetable prep. Higher horsepower usually also means a heavier induction motor and better sound insulation, not just more grinding force at the plate.
What genuinely must never go down a disposal?
Grease and cooking oil lead the list, since they leave the sink as liquid and set solid in the 1-1/2 inch kitchen branch. Then coffee grounds and eggshells, which pack into sludge; pasta and rice, which swell; celery, artichoke, and corn husks, which wrap the impellers; bones and fruit pits; and anything non-food. Run cold water while grinding, because hot water melts fat and carries it deeper.
Why do some buildings not allow a disposal at all?
Condo and HOA rules often prohibit them because the building's kitchen stack is old shared cast iron, and the added solids cause backups that flood the lowest unit. Check the recorded CC&Rs before buying a unit. Commercial kitchens have a separate reason: food waste grinders are generally not permitted to discharge into a grease interceptor without approval from LA County Public Works.
My dishwasher drains into it. What is the knockout plug?
New disposals ship with a cast plug sealing the dishwasher inlet. It has to be driven out with a punch or screwdriver and the loose slug retrieved from inside the grinding chamber before the hose goes on. Leaving it in place is the most common reason a dishwasher will not drain after installation. California also requires the dishwasher drain to be protected by an air gap or an approved high loop.
What are the electrical requirements?
A disposal is an appliance load and should sit on its own branch circuit, typically 15 or 20 amps, not shared with the dishwasher. It can be hardwired or cord-and-plug connected, and NEC 422.16(B)(1) governs cords for in-sink waste disposers, requiring a grounding-type plug into a receptacle that stays accessible in the cabinet. The wall switch belongs above the counter, within sight, so power drops before anyone reaches into the sink.
Do I need a permit just to swap a disposal?
A like-for-like replacement on the existing circuit and existing drain connection is ordinarily maintenance, not permitted work. It becomes permitted work when an electrician runs a new circuit or adds a receptacle, or when the drain, trap arm, or vent is altered. LADBS issues plumbing permits for modification of drainage and vent systems and electrical permits for new circuits. We tell you which applies before installing.
I am on a septic system. Is a disposal a bad idea?
It adds solids and organic load, so the tank fills faster, needs pumping more often, and the leach field takes more strain. Some onsite systems permitted through LA County Environmental Health were sized without a grinder in the calculation. If you install one, plan a shorter pumping interval and use it sparingly. A batch-feed unit with a good strainer is the more conservative setup.
It hums but does not spin. What is wrong?
The motor has power but the impeller plate is jammed, usually by a bone, a fruit pit, or a piece of metal. Switch it off and shut the breaker off first. Most units accept a 1/4 inch hex wrench in the socket on the underside; work it back and forth to free the plate, then lift the object out with tongs, never a hand. Press the reset button underneath.
Will a new disposal fix my slow kitchen drain?
Usually not. A slow kitchen line is nearly always the 1-1/2 or 2 inch branch past the trap, coated with grease and, in older Los Angeles homes, scaled galvanized or cast iron. A new unit grinds finer but the pipe is still narrowed. A camera down the kitchen line shows the diameter that is left. Cleaning or replacing that branch is the actual fix.
What changes the price of an installation?
The unit itself, where horsepower, motor type, and sound insulation drive most of the difference, plus whatever the existing setup needs. Adding a dedicated circuit or a switch brings in an electrician. A corroded cast iron or galvanized trap arm has to be replaced rather than reused. Sink flange condition, mounting compatibility, and cabinet clearance all add or remove time. We quote firmly after looking under the sink.
