I ave a Sinkmaster 850 garbage disposal that leaks when the water faucet is turned on and draining into the disposal portion of the sink. The disposal does not have to be turned on to leak. The leak is at the bottom of the unit. How can I fix this leak? I guess I need a schematic of the unit to know what is causing the leak. I assume it may be an O ring seal part, not sure.
I do not see disposals on your list. I am choosing a category to allow this to submit.
I have had these apart. The leak is from a seal around the motor shaft. By the time it is leaking the shaft has pitted to the point a new seal will not repair it. Getting it apart can result in damaged parts as it is sealed together with very tight tolerances and a glue like sealer.

The problem is that the plumber's putty seal has a void in it. Disassemble the drain and replace the plumbers putty and you will no longer leak.
