After connected kitchen sink in first floor (Texas home no basement) to the soil stack which comes from second floor, I need to test. When I put drain plug on main stack outside, first level bathroom flooded, apperantly all connect together since inspector suggested me to that. Is there a way to test only using soil stack there is a clog adapter on soil stack which is almost 5 feet above the flooor? I am thinking using long hose to inflate the plug, is it possible, any suggestions really appreciated.

I doubt you can thread a hose down that test tee above.
We normally install a test tee under the new line to test, then use a Cherne inflatable test ball in the tee. 1703015619550.png
 
I see that make sense. There is no place to install the tee since I install the wye just above the slab. Thanks for the response.
