Garbage Disposal Repair & Installation in Federal Way, WA
Most disposal calls are one of three faults, and one of them you can usually clear yourself in five minutes. The more interesting question is what the disposal has been doing to the drain line behind it, because that is where the real bill hides.
Humming, silent, or leaking
A unit that hums but does not turn is jammed, and the motor is drawing current without moving. Switch it off at the wall, and do not keep flipping it on, because that is how a jam becomes a burned out motor. Most units have a hex socket underneath that lets you free the plate by hand with the supplied key, and there is a reset button on the base that usually needs pressing afterwards.
A unit that is completely silent is an electrical problem rather than a mechanical one. Check the reset button first, then the breaker, then the switch. If all three are fine, the motor has gone and the unit is a replacement rather than a repair.
A leaking unit depends entirely on where the water is coming from. A leak at the sink flange on top is a reseating job. A leak at the dishwasher inlet or the discharge tube is a connection. A leak from the body of the unit itself means the housing has corroded through and nothing can be done for it.
What a disposal does to the pipe downstream
This is the part that matters more than the appliance. A disposal grinds food fine enough to leave the sink, and people take that as evidence the food has left the building. It has not. It has entered a horizontal drain line at low velocity along with warm water and whatever fat came with it.
Fat cools within a short run of pipe and coats the wall. Fine food particles stick to that coating. Over years the line narrows, which is exactly the mechanism behind the kitchen grease blockages that make up a large share of our drain cleaning work in this city.
So a house with a disposal that has been used heavily for a decade has a kitchen line worth thinking about, and the fix when it eventually blocks is usually jetting rather than cabling, because the deposit is on the wall rather than in the middle.
| What it does | Likely cause | Can you fix it |
|---|---|---|
| Hums, does not turn | Jam at the impeller plate | Usually yes, hex key and reset button |
| Completely silent | Reset tripped, breaker or switch | Check all three, then call |
| Silent after all three checked | Motor has failed | No, replace the unit |
| Leaks at the top of the sink | Flange seal | Repair job, reseat it |
| Leaks from the body | Housing corroded through | No, replace the unit |
| Drains slowly after grinding | Build up in the line, not the unit | Clean the line, not the disposal |
Try the hex key underneath
Most hums are a jam you can free yourself in five minutes. If that does not do it, (253) 478-2671 picks up.
The rules that actually matter
Grease and cooking fat should never go in, disposal or not. Pour it into a container and bin it. This is dull advice and it is genuinely the single highest value thing on this page.
Fibrous material such as celery, artichoke, corn husks and onion skins wraps around the impellers rather than being cut. Starchy volumes such as pasta, rice and potato peel expand and form a paste that is very good at coating a pipe. Coffee grounds settle and accumulate. Bones and fruit stones are simply harder than the unit.
Run cold water rather than hot while grinding and for a good while afterward. Cold keeps fats solid so they get cut and carried out rather than melting and redepositing further along, which is the opposite of what most people assume.
Repairing versus replacing
Repair is right for a jam, a tripped reset, a failed switch, a leaking flange or a leaking connection. All of those are cheap and none of them means the unit is finished.
Replacement is right when the housing itself leaks, when the motor has failed, or when the unit is old, underpowered and jamming repeatedly on ordinary use. A modestly better unit installed properly is usually the better spend at that point than a third repair.
Installation is another place where the surrounding parts matter more than the appliance. The shutoff under the sink, the trap arm and the dishwasher connection all get disturbed during the work, and in a house of this age a valve that has not moved in twenty years does not always survive being asked to. Having those checked while the cabinet is open is the cheap version of that conversation.
The line the disposal empties into
The appliance is rarely the interesting part. A slow sink behind a working disposal is a drain problem, years of accumulated coating usually calls for jetting rather than cabling, and if several fixtures are misbehaving together the fault is in the main line and has nothing to do with the kitchen at all.
We fit and repair units the same way in Kent and Des Moines.
QUESTIONS
Garbage disposal questions in Federal Way
Hot or cold water while the disposal runs?
Cold, and keep it running for a while after the noise stops. Cold water keeps fats and oils solid so they get chopped and carried out of the house with the flow.
Hot water melts them, which feels like it is helping and simply moves the problem further down the pipe where it cools and sticks to the wall. That is the mechanism behind a large share of the kitchen blockages we clear.
Can I use a chemical cleaner to unclog the sink under a disposal?
We would strongly rather you did not. Caustic cleaner sitting in a chamber with metal impellers and a rubber splash guard is unkind to both, and it rarely reaches a blockage that sits in the horizontal run beyond the trap.
It also means the next person to open that connection meets a chamber of chemical, which is a genuine hazard rather than an inconvenience.
My disposal is fine but the sink drains slowly. What is that?
Almost always the drain line rather than the appliance, and in a house where a disposal has been used regularly for years it is usually a coating of fat and food fines on the pipe wall rather than a discrete clog.
That responds to jetting rather than to anything done at the unit. Replacing the disposal in that situation is a common and completely wasted expense.
The unit is rarely the problem
A slow sink behind a working disposal is the line, not the appliance. Call before replacing anything.
