My contractor just installed 2 disposals for me, two different brands, and both are doing the same thing. I'm thinking the install was done incorrectly.

Having installed a few of these, I can't imagine what an installer could do that
would make the unit put out a loud click when starting. The blades on some
do make that noise. They are loose and made to move. With the power off
you can put your hand down in there and carefully feel them and see what I mean.
Also you can call the manufacturer's support line, see what they say.

First off, the InSinkErator Evolution is my go-to disposal. I've had one for years with
not a single issue and I've bought and installed a few as housewarming gifts. Never
heard one complaint - and it's mostly family, so I would know.

Second, on rare occasions, mine - when fairly empty - will throw the blades and make a click.
Well, more of a clack. Never bothered me, probably because I know what is making the noise.
