Friends, I have a dual kitchen sink. The left sink has a garbage disposal. If I fill up the left sink several inches high with water, and let the water out with the disposal on, water will start filling up on the right no-disposal side. I have a picture that shows the current setup, where the pipe is straight out horizontally from the disposal to a Tee. I don't know what is normal, that is, did the previous owner do this incorrectly, is this actually normal, or do I need to re-plumb with a different setup. I saw a lot of setup pictures on youtube and on the internet, and they would have me believe that this is correct. But I am also am including one picture that shows a p trap from both the disposal and the other sink, that eventually connect to a wye. What's right, as the current setup that makes a mess in the non-disposal side just can't be right.
