Garbage Disposal Repair & Installation

A jammed or leaking disposal usually drags the whole kitchen drain down with it. We repair, unjam, and replace disposals, and we fix the under-sink drain and trap troubles that tend to ride along with it. We'll find the real problem and tell you what it'll take to set it right.

Same-day on most calls. Upfront pricing before any work.

What it costs: Flat-rate for a straight swap. Price moves with the horsepower of the unit and whether the existing drain work needs redoing, which we tell you before we start rather than after.

Signs you need garbage disposal repair

  • Disposal hums but won't turn (jam)
  • Leaking from the bottom or the drain connection
  • Won't power on at all

How we handle it

  1. Unjam or diagnose

    Many ‘dead’ disposals just need the reset and a manual free-up.

  2. Repair or replace

    Leaks from the housing mean replacement; drain leaks we re-seal.

  3. Check the drain

    We make sure the trap and branch drain are clear while we're under there.

What to know about garbage disposal repair in Arizona

Most disposal failures aren't the motor. They're a jam or a reset, and you can often fix them yourself before you call. If the disposal hums but won't turn, something's wedged in the grind chamber. Kill the power, free it with the hex wrench in the bottom socket, then hit the red reset button underneath. If it's totally dead, the reset button or the breaker tripped. We'd rather tell you that over the phone than charge you for a button push. When it's truly the motor, leaking from the bottom shell, or the chamber's rusted through, that's a replacement.

What you feed it decides how long it lasts, and Valley homes have a specific hazard: stringy, starchy waste plus hard water. Fibrous stuff (celery, artichoke, corn husks), grease, coffee grounds, eggshells, and especially starchy peels (potato) are the classic killers. They either wrap the impellers or congeal into a paste that, combined with our hard-water scale, builds up and clogs the trap and line downstream. Always run cold water during and after grinding so grease stays solid enough to flush. A disposal is for incidental scraps, not a stand-in for the trash.

Horsepower and build quality are a real choice, not marketing. A 1/3 HP builder-grade unit is underpowered and jams constantly. For most households a 3/4 HP or 1 HP unit with stainless components grinds harder waste without stalling and lasts a good deal longer. If noise bothers you, better units have sound insulation. We also pay attention to the discharge plumbing. A disposal married to an old, scaled, or poorly sloped drain arm will keep backing up no matter how good the unit is, so sometimes the honest fix includes the drain, not just the appliance.

One detail people miss: if you have a dishwasher, its drain hose ties into the disposal, and a new disposal ships with that inlet plugged. That plug has to be knocked out, or the dishwasher won't drain and you'll think the new disposal is defective. We also make sure there's a proper high loop or air gap so dirty disposal water can't back-siphon into the dishwasher. That's both a code and a sanitation issue. These are the small things that separate a clean install from a callback.

Garbage Disposal Repair, frequently asked

My disposal just hums, is it dead?
Usually a jam. We free it and hit the reset. We only replace it if the motor's gone.
Best disposal for hard water?
Stainless grind components hold up better here. We'll point you to a model that lasts.
My disposal just hums and won't spin. Did the motor die?
Usually not. Something's jammed in the grind chamber. Cut the power, use the hex wrench in the socket on the bottom to free the impellers by hand, then press the red reset button underneath. If it spins free after that, you're fine.
What should I never put down my disposal?
Grease, coffee grounds, eggshells, and fibrous or starchy waste like celery, corn husks, and potato peels. In our hard water especially, that stuff congeals and builds up in the trap and line. Always run cold water during and after grinding, and treat the disposal as a scrap-catcher, not a trash can.
Is a more powerful disposal worth it?
Generally yes. The 1/3 HP builder-grade units jam constantly and wear out fast. A 3/4 HP or 1 HP unit with stainless components handles tougher waste without stalling and lasts a lot longer, and the better models are insulated so they run quieter.
I installed a new disposal and now my dishwasher won't drain. Why?
New disposals ship with the dishwasher inlet knockout plug still in place, and it has to come out during install or the dishwasher can't drain through it. It's a common DIY miss. We also make sure there's a proper high loop so dirty water can't back-siphon into the dishwasher.
There's water leaking under the disposal. Can it be fixed?
Depends where it's leaking. Leaks at the sink flange or the discharge connections are repairable, and we'll reseal or replace the fitting. But if it's leaking from the bottom shell of the unit itself, the internal seal has failed and the disposal needs replacing. That housing isn't serviceable.
