Vanity - single sink -> double sink

[cinderbike]

Hey everyone,

Redoing my bathroom and wondering how I would go about doing this. I have the vanity out and the wall opened up, like so:



Can someone point me to a diagram or whatever I need to do to follow IRC (which is what I've been told is what I should be doing here).

Thanks!

With the 2" coming up, I use a 2.0" x 1.5" x 1.5" x 1.5" double fixture cross and some medium 90 to pick up the lavs.

Thanks. Any code procedures on the copper or just split as I normally would? I was going to sweat in some tees and run it where it needs to go.

Also, how do I check for leaks in these drain pipes? Funnels and lots of water? Want to make sure its water-tight before sealing the wall.

They make temporary fittings that fit on the end of the trap arm that allow a hose to run water through.
Two lavs on 1/2" is not a problem. Go ahead and tee in the wall and stub out for future stops.

What would those fittings be called? My googling attempts came up empty.

Okay, does this look alright?

Ignore the burn marks.
