Problem with test plug location

[akadmyster]

I am an owner builder starting the installation of the DWV lines on a two story attached add-on that I am building.

I know it is recommended (not sure about code) to have a text plug at the base of the stack to isolate the new dwv lines for testing.

If I do that .... my 2" lav drain line is too high (about 29"). See picture.

I think I have to have a cleanout here also which the text plug would be used.
In order to move the 2" drain line lower .... I need to delete the text plug or relocate above the connection (see pic).

I can isolate the whole system via the exterior clean out.

Question .... would this application meet code in California?

You can also put a test fitting on the lav line.

Is the underground piping already tested?

For a cleanout postion

For a test tee.

Yes ... the underground lines have already been tested and inspected.

I'm not worried to much about isolating the system for testing .... its whether I am required to have a test plug at the stack base or is that just for ease of testing.

If I can put an actual cleanout (not text plug as shown) above the lav connection and do away with the text plug ... I'll be good.

The test fitting doubles as a cleanout. test tee

And yes, the work above slab will need testing.

I think I hit the wrong reply button......so if this posts twice ... my apologies.
I will go ahead and install it as per the "my preferred picture" with the wye below and the test tee on top which will give me proper lav drain installation.

I appreciate your help and will most likely have a few more questions in the coming week.

Wouldn't the lavatory drain line connection be a sanitary tee rather than a wye?

Yes .... wrong terminology.
You are correct.
