I need some advice on hooking into my drain line for a second sink. I can send a pic to see what I am dealing with. I am fine with the water lines, My email is mlojacono@bellsouth.net
Thanks.

upload a photo to a hosting service like Photobucket?

Then post a link here using the img brackets in the how to show images guidance on this page

it might be as simple as keeping the trap close to the center and piping it like a double bowl kitchen sink.

Finally able to link pictures:

Please see my link below. I look forward to any help.

if there are no drawers in the middle, just pipe it like a double bowl kitchen sink. BTW, your trap is installed backwards.

There is drawers in the middle of cabinate, but there is some space at back of drawers.

then stack 2 sanitary tees inside the wall. the top one faces out and the one below faces to the left with a short piece of pipe and a 90..

Can I use 1 1/4 off the 2 inch line, or is 1 1/2 recommended?

Code does allow 1 1/4" pipe to be used in that situation, but you must also use drainage fittings, not short sweep pressure fittings.

Is an alternate to use a 4-way be instead of 2 tees? Also, should the line going to the new drain be exactly level or can it slope down a tiny bit?

It might be best to use a back to back fixture fitting, or a double sanitary tee rather than stack 2 tee's. The piping needs to be sloped up as it leaves the tee.
