The quick answer

Silent, humming, jammed, leaking and smelling are five different faults. Silence is a power problem, a hum is a seized flywheel, and a leak from the shell means the unit is finished. Which one it is also decides who is supposed to pay for it.

Go straight to the one that sounds like yours:

Four symptoms cover nearly every disposal fault, and they barely overlap. One question comes before all of them: whose machine is it.

What this site is

SinkGrind is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We carry out no work, we sell no equipment, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

First, whose disposal is it

In an owner-occupied house the disposal is your appliance on your drain line. In a rented apartment it is usually the building's fixture, the landlord's to repair, and the drain it empties into is shared with other kitchens. Calling a contractor yourself in the second case can leave you with a bill you did not owe.

We hold the housing mix for 4,387 towns across 38 states. Find yours on the coverage page.

Then the symptom, which is unusually decisive

Complete silence is a power fault: the reset button, the breaker, or the switch. A hum with no rotation is a jam, and it is the most common call there is. Water in the cabinet depends entirely on where it starts. A smell is residue, not a fault at all.

And the thing that prevents most of these

Grease, fibrous vegetables, coffee grounds and bones cause more disposal failures than age does. EPA is blunt about the first one: never pour cooking oil or grease down the drain. The full list explains what each one actually does.

When not to call at all

A tripped reset costs nothing to push. A jam is often freed in ten minutes with a hex key. A smell is a cleaning job. Routing those to a contractor wastes your money and their time, so we say so rather than take the call.

Where we route calls

What happens when you call

No form, no quote tool, no waiting for an email.

  1. You tell us what the water is doingOne short conversation. If it turns out to be something you can fix in five minutes, we will say so.
  2. We route the callWe match your ZIP code to an independent contractor who already covers your area — not a call center three states away.
  3. They quote, you decideWe do not set prices and we never charge you. The contractor pays us for the introduction.

What to do first

Four things worth doing first. They cost nothing and they can keep a small problem small.

  1. Shut off the water closest to the problemUnder a sink or behind a toilet there is usually a small valve on the supply line. Turning it clockwise stops that fixture without shutting off the rest of the house.
  2. If you cannot find it, use the mainUsually where the supply enters the building — a basement wall, a crawl space, or a covered box near the street. Then open the lowest tap in the house, which drains the standing water out of the pipes instead of out of the leak.
  3. Water and electricity: stay out of the roomIf water has reached an outlet, a panel or an appliance, switch that circuit off at the breaker before going near it. If you cannot do that safely, do not go in, and say so when you call.
  4. Photograph it before anything is movedInsurers ask for it, and a contractor can tell more from a photograph of the leak than from a description of it.

And one case where the answer is not to call us. If the water is surfacing on the street side of your meter, that is the utility's line and not yours. Report it to your water utility — they do not charge a homeowner to repair their own main.

Pushed the reset button already?Then it is worth a contractor rather than another ten minutes with a hex key. Tell us what it is doing — silent, humming, leaking or smelling — and we will route you. Free to you, always. Every kind of plumbing call is welcome here.
