That might be the case here, as there was this rusty crack
in the side of the old Emerson garbage disposal unit:

Who knows how or why this crack is there?

However, the fact the washing machine was backing up into the
kitchen sink, tells me that the sink was filling with water
because the drain pipes were clogged solid somewhere deep
under the house.

I suspect the kitchen sink backing up filled the disposal unit
with standing water - which - leaked profusely out this crack?

But I have no proof.
