Garbage disposal plumbing under two sinks

[yafengc]

It seems that the plumber did the wrong installation my new garbage disposal. So when I turned on garbage disposal, the water overflow to anther sink.

Should I follow the right installation from the link below:https://terrylove.com/forums/index.php?threads/garbage-disposal-plumbing-done-wrong.59911/

The links you posted have a good methods. There is more than one right way.

This is an alternative, The tee is a Center Outlet Waste Slip Joint Tee. You can't interchange that kind of tee with the other type. I am not a plumber.
