Hi All -
With a growing family, I'm looking to replace my existing single sink and vanity (which is conveniently 60 inches wide) with a double vanity and sink. Unfortunately there is only a single existing drain, but thankfully it lines up perfectly with the right side of a double sink. I'd like to add another drain line for the left sink - ideally without having to remove too much wall above where the vanity and sink will be. My current sink drain Tees off of the main stack and then Tees back in above for the vent (I've seen it and taken notes when I had to open up the other side of the wall a year or two ago). I have attached an image of my current layout - labeled existing. I am interesting in knowing if its acceptable to Tee a new drain into the existing waste line as shown in my image Proposal #1. If not, I'm assuming Proposal #2 is acceptable? I'd prefer #1, just because it requires less work in the visible damage range, but if #2 is the only acceptable solution, I'm willing to do it right. Thank you in advance for any guidance -
