Disposal Humming, Silent or Leaking? Garbage Disposal Repair and Installation in Oviedo, FL, Explained

A disposal usually tells you what is wrong before anyone opens the cabinet. A hum, a silence and a puddle each point somewhere different. Call Oviedo FL Expert Plumbers and describe which one you have, and use this page to decide whether it is a quick reset, a repair or a replacement.

The same machine can have two problems at once, such as a jam that overheated the motor. Describe everything you noticed, in the order it happened, when you call.

Freeing a jammed disposal safely: power off first, hands never inside

  1. Turn the disposal off at the wall switch, and then switch off its breaker if you can find it.
  2. Never put a hand into the disposal, even with the power off. Use tongs or pliers to lift out anything visible.
  3. Look underneath for a hex socket at the center of the base. Many models take a hex key that turns the plate back and forth.
  4. Press the red reset button on the base once the plate turns freely.
  5. Restore power, run cold water and test with the water running.

If it jams again right away, something is lodged or the motor is failing. Repeated resets of a unit that keeps tripping hide the cause and wear out the motor. At that point a service visit costs less than a burned-out replacement.

Bones, fruit pits, fibrous scraps, grease and anything that is not food are the usual jam makers. Cold water running during use and for a few seconds afterward helps carry waste out of the unit and into the line.

A leaking garbage disposal: finding the source under the sink

Dry every part with a towel, put a sheet of paper towel under the unit, run water and check where the paper gets wet first. A disposal has several joints, and the leak's location decides the repair.

Where a disposal leaks and what usually fixes it
Where the water showsWhat it usually meansTypical repair
At the top, where the unit meets the sinkThe sink flange seal has failedRemove the unit and reset the flange seal
At the dishwasher inlet on the sideA loose clamp or a worn hoseTighten or replace the hose and clamp
At the discharge pipe leading to the wallA loose or worn gasketReseat the pipe with a new gasket
From the body or the bottom of the housingA cracked or rusted housingReplace the disposal

A leak from the housing cannot be patched. A drip that returns after a tightened joint usually means a worn part, not a joint that needs another turn. If the leak has soaked the cabinet floor, say so when you call, because the wood may need attention too.

Repair the disposal or put in a new one? Questions to settle it

A jam, a seal and a clamp are small repairs. A burned-out motor, a cracked housing or a unit that has leaked from several places is usually the end of that disposal. The answer should come from what the plumber finds, not from a blanket rule.

  • Is the failure a part that can be replaced, or the housing or motor?
  • Will the same unit still be sold, or does a replacement have a different mounting?
  • How does a new unit compare in size, power and sound?
  • Is the old mounting reused, and is it in good shape?
  • What are the costs of repair and replacement, written side by side?

Callers often want a price by phone before committing to a visit, and that is fair. Be ready to say the make if you know it, what it does, how old it is, and whether it is wired in or plugged into an outlet. A phone figure is an estimate. It can change when the plumber sees the mounting and the electrical setup.

Installing a new disposal: electrical, mounting and the dishwasher plug

A disposal install looks simple, and a few details trip people up. The unit needs power, either a cord to an outlet under the sink or a hardwired feed to a switch. It needs a sink flange that fits the drain opening, and the mounting must hold a heavy, vibrating unit.

  • A switched outlet or a hardwired circuit under the sink, and a wall switch
  • A sink with a standard drain opening and enough cabinet depth for the new unit
  • The knockout plug in the dishwasher inlet removed if a dishwasher drains into the unit
  • A discharge pipe and trap that line up with the wall drain
  • Safe disposal of the old unit

The dishwasher plug is the detail most often missed. Many new disposals have a plug inside the dishwasher inlet, and if it is not knocked out, the dishwasher cannot drain. Ask the installer to confirm the dishwasher drained during the test.

The size of the motor should fit the household. A heavy motor is not always better, because it takes more room and may cost more. Ask what the plumber would choose for your cooking habits and why.

When the sink will not drain, the disposal is not always to blame

A sink that drains slowly with the disposal running often has a clog in the pipe after the unit. A disposal grinds food and sends it down the line. If the line is partly blocked with grease, the scraps settle and a clog forms again, no matter how many times the disposal is reset.

Two basins with a disposal on one side and water rising in the other point toward the shared line. If you suspect that, read clearing a kitchen drain that keeps returning and, for heavy grease buildup in the pipe, how high-pressure water cleaning differs from a cable.

A disposal does not stop a pipe from clogging. The most reliable fix is to keep grease and fibrous scraps out of the sink to begin with. Wipe pans into the trash, and run cold water while the unit works.
