How to diagnose a problem with a garbage disposal-This article deals with leaking around the top of the disposal. This information is specifically for newly installed disposals, not exisitng units.
Leaking around the top of a garbage disposal is usually caused by one of the following.
Not enough sealant used-If there is too little or no sealant used under the sink flange than it can result in leaking around the sink flange.
Black rubber or fiber gasket-The gasket needs to be seated flat against the underside of the sink.
Loose screws-If the mounting hardware screws are loose this will allow for movement which can result in leaking.
Damaged cushion mount- Replace part (Moen Part # 1824).
