When rubber gaskets age, they can develop leaks. The gasket can dry up, crack, and leak when it is repeatedly exposed to long periods of disuse where no water is present in the drain pipe. Should an older garbage disposal be removed and then placed back, it will require a new rubber gasket to again achieve a watertight seal. Moreover, if a gasket is not evenly locked on all three sides, then it will develop a leak.
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 company Waited hired has an “A plus” rating with the Better Business Bureau and has been in business for 14 years. They didn’t do anything wrong, so CBS4 is not naming them. They didn’t want to discuss the charges. They stand behind their billing, but they didn’t like having a customer who was unsatisfied. The company agreed to refund $400 to Waite.
IMPORTANT: Whenever you are working on your garbage disposal, inserting items, and/or inserting body parts into your garbage disposal unit, it should be UNPLUGGED and the POWER TO THE GARBAGE DISPOSAL UNIT SHOULD BE OFF! Failing to do so will put you at risk of SERIOUS INJURY. Also, if possible avoid placing your hands directly near the blades at the disposal. If you can, instead use a tool to wedge out items or check the blades for blockage.
Another common cause for a leaking garbage disposal is the disposal flange. A leak at the very most upper area of the garbage disposal could be the garbage disposal flange which goes through the sink. A garbage disposal flange should be sealed with Plumber’s putty and then tightened from underneath the sink. If this is not tight enough or if it has managed to come loose (which can happen) then the garbage disposal will have to be taken down so the flange can be resealed and then the garbage disposal can be rehung.
