Read on to keep the cash you’d otherwise hand over to a pro.

Prepare to find the leak

Prior to testing the garbage disposal for leaks, unplug it at the wall outlet and turn off the power from the breaker box to prevent electrical shock. Then insert a watertight sink stopper into your sink drain and wipe the unit dry with a clean cloth. In any handy container, mix a few drops of food coloring into a few cups of water, and pour the dyed water onto the sink stopper to help you locate the leak.

Investigate the source

  • the top, where the disposal meets the sink drain

  • the side, where the dishwasher hose or main drain pipe connects to the disposal

  • or the bottom of the unit

  • Inspect each of these locations while gliding a light-colored rag over the unit; the dyed water will readily show on the rag and reveal the location of the leak. If a leak isn’t immediately apparent, remove the sink stopper and pour a few more cups of dyed water down the sink drain, then check for leaks again. Leaks near the top of the unit are more likely to show themselves while the sink is plugged, while side and bottom leaks are more noticeable while the sink is unplugged.

    The metal sink flange that sits directly inside the sink drain is typically sealed around the top with plumber’s putty (a clay-like sealant) and then secured from under the sink with bolts. If the plumber’s putty deteriorates, or the bolts loosen, the flange can no longer form a watertight seal between the sink drain and the disposal—which could cause a leak at the top of the unit.

    To reseal the leaky flange, you must first detach the garbage disposal. Start by loosening the screws securing the main drain pipe to the disposal, then loosen the screws in the metal clamp securing the dishwasher hose to the disposal and detach the drain pipe and dishwasher hose from the disposal. Loosen the screws in the mounting ring that connects the disposal to the metal mounting assembly beneath the sink, then pull down the disposal and carefully set it on a clean, dry surface. Loosen the bolts in the mounting assembly with a wrench, then pull down the mounting assembly and set it near the disposal.
