Overview

Disposal problems are 80% the same five issues — most fix in one visit

When a disposal stops working, it's almost always one of five things — jammed flywheel, tripped overload, blown motor, leaking drain or housing, or worn impellers. The first three are usually a 30-minute fix. The last two mean it's time to replace. Our techs carry common Insinkerator, Moen, and Waste King units on the truck so we can do a same-visit swap if yours has reached the end.

A leaking disposal is the bigger problem most people don't catch in time. The seal between the body and the sink flange wears out, water seeps under the sink for weeks, and the cabinet floor warps and grows mold before anyone notices. If you see standing water under the sink — even a little — that's a same-week call, not a "next month" call.

What we repair

  1. Jams — bone, fruit pit, silverware. Free the flywheel with the hex wrench, reset, test.
  2. Tripped overload — small red button under the unit. Most "dead" disposals are just this.
  3. Leaks at the sink flange — top seal worn, replace plumber's putty or silicone, retighten.
  4. Leaks at the drain elbow — discharge tube gasket failed, $35 part.
  5. Leaks from the body — internal seal failed, time to replace the unit.
  6. Humming but not spinning — motor seized, almost always a replace.
  7. Slow drain — usually a clog downstream, not the disposal itself.
  8. Loud grinding or vibration — worn impellers or shifted housing — replace.

What we install

Standard 3/4 HP disposal install is flat-rate labor — we install Insinkerator (Badger, Evolution Compact, Evolution Pro), Waste King L-2600/L-3300, Moen GX/GXP, KitchenAid. You can supply your own from Home Depot, Lowe's, Costco, or Amazon, or we can spec and supply. Septic-safe units (Evolution Septic Assist) for homes on septic systems. Stainless steel and sound-insulated models for quieter kitchens. We always replace the mounting flange, drain putty, and discharge gasket as part of every install — that's the difference between a leak-free 10 years and a leak in 18 months.

North Louisiana disposal issues

Hard water is a factor here. Water averaging 15-25 grains per gallon of hardness builds calcium scale on the impellers and inside the grind chamber, which dulls the cutters and makes the motor work harder. Disposals in soft-water markets last 12-15 years; with hard water and no softener, plan on 7-10. We'll mention the softener option if it makes financial sense for your situation.

Also: dishwasher discharge knockout plug. If you're installing a new disposal and your dishwasher backs up the first time you run it, the plug for the dishwasher inlet wasn't punched out. Common rookie mistake we fix on first-call jobs from other plumbers.

What Mark Johnson & Sons does differently

Warning signs

Signs Your Garbage Disposal Needs Repair or Replacement

Most disposal issues escalate quickly — leaks especially. Catch them early.

  • Disposal hums but doesn't spin (jammed or motor seized)

  • Disposal is completely dead — no sound, no light

  • Water leaking from underneath onto cabinet floor

  • Water pooling at the sink-side flange where it meets the basin

  • Slow drain or backup into the second sink basin

  • Loud metallic grinding or rattling during operation

  • Shaking or vibration severe enough to knock dishes loose

  • Persistent musty or sewer smell from the disposal

  • Disposal trips the breaker repeatedly

  • Unit is more than 10 years old and acting up

The Process

How a Garbage Disposal Service Call Works

Mark Johnson & Sons Plumbing technician diagnosing a leaking garbage disposal under a kitchen sink

On the truck

Professional tools, parts, and diagnostics — every call.

  1. Quick diagnosis

    Tech checks under the sink, listens to the unit, tests the reset button, and rotates the flywheel from underneath. Usually a 5-minute diagnosis to identify which of the common five problems you have.

  2. Flat-rate quote

    You see the repair price OR the replacement price before any work begins. If the unit is 10+ years old or the body is leaking, we'll show you the replacement option side-by-side so you can choose.

  3. Repair or replace

    Jams, overload trips, and discharge gasket leaks fix in 20-45 minutes. Full disposal replacement runs 45-90 minutes including new mounting hardware, putty/silicone seal, and dishwasher knockout if needed.

  4. Test under load

    Run cold water, run the disposal with food scraps, check for leaks at every joint — sink flange, body, discharge tube, P-trap. Verify dishwasher discharge if connected.

  5. Warranty

    1-year warranty on labor and any Mark Johnson & Sons-supplied parts. New disposal installs include the manufacturer warranty (Insinkerator Evolution = 7-12 years; Waste King = 8 years; Moen = 7 years on premium models).

FAQ

Garbage Disposal FAQs

A standard 3/4 HP disposal install is flat-rate labor — you supply the unit (Home Depot, Lowe's, Costco) and we install. Premium 1 HP sound-insulated units take a bit more to fit. We always include new mounting flange, fresh putty seal, and discharge gasket as part of the install — those are the parts that fail at 18 months on cheap installs.
