I am installing a new disposal under my double kitchen sink. I have a dishwasher but no disposal previously therefore there is no existing infrastructure for the new disposal. For what it's worth the disposal is an Insinkerator Evolution Septic Assist.
Below are a couple of pictures of my existing plumbing under the sink. You can see the dishwasher outlet coming from the right in to a P-trap, the drain sticking up from the near center of the bottom of the cabinet with a vent cap on the top, and another P-trap below the left sink drain pipe.
I have seen Terry's drawing showing a good disposal plumbing install but I have a couple of questions:
1. How should I modify things with the drain being in the center (or will I need to modify them at all?)? Can I just install the disposal on the left side? I will probably have to lower the horizontal pipe between the two sinks a little in order for it to fit in to the disposer (not sure though).
2. Can I purchase a longer dishwasher discharge hose and plug it in to the disposal? Do I need to use an airgap as well (apparently one was not installed originally). Once I hook up the dishwasher to the disposal can I just cut off the other P-trap for the dishwasher and cap it off?
Thanks for any advice / suggestions you can offer!
