Move Sink Drain

The wonderful designer at Home Depot thought it would be a great idea to move my clients kitchen sink down 3 feet. Here's my question:
Take a look at the photo attached- can I extend out the drain to the left three feet or do I need to move the vent as well?

Re: Move Sink Drain

You're fine, but loop it up and over if you want.

Re: Move Sink Drain

Check with your states code, odds are you'll have to increase the drain arm size to 2" due to increased run length. You'll also need stud shoes instead of nail protection plates.

Two other options, AAV (again if allowed by code) or 1-1/4" revent 6" above the spill lip.
