DYI Pluming rough in sanity check

[ahbradford]

Hi all, I'm building a small cabin and I'm to the point where I'm putting in plumbing drains. This is in Mariposa, CA.

I've been researching plumbing codes, and I did my best here and I'm curious if anybody in the know could sanity check what I've came up with up here for the drainage and vents.

All the pipe is 2" ABS, and the double fixture is 2" all around (is this OK?) The trap adapter facing the camera is for the kitchen sink, and the other is has a 1.5" reducer then trap adapter for the bathroom lavatory

Nothing has been glued yet, and even though it doesn't really look like it on the pic, all the slopes are correct.

I really appreciate anybody's help and any feedback is greatly welcome

Not sure on the plumbing part, I'm not a plumber.

Are you studs 2x4 or 2x6? They look wide, so you might be OK with the 60% rule for non load bearing walls.

What size pipe can I put through a 2x4

I am finishing my basement. I put in an inside wall for a bar with a sink. I need to run my drain pipe through the wall. Can I run a 2" drain pipe through a two by four? Thanks for any help, Pat McCurdy :)

Not sure how far your pipes are from the stud edge, but see if you need any nail plates, as well.

The vent 90 is just unnecessary, as regular (cheaper) 90 is fine. Technically, the elbows on the sink arms should be long sweep as per the rule that all horizontal piping must use drainage fittings.
The Clean-out 90 should be long sweep to aid in snaking, but, it will work with difficulty.
The fig 5 should have been a 2 x 1-1/2x1-1/2x1-1/2 but no harm in up-sizing
