#1 2" out the roof is not code here, I think it will have to be changed to 3" and a cap installed over it that will be cut off later OR a test ball inflated inside of each.
#2 Remove toilet and plug with test ball.
#3 3 san Ts will have to be pluged with test ball or capped.
#4 kitchen sink needs to be disconnected and capped or ball inflated.
#5 utility sink dito.
#6 shower drain dito.
#7 Tub drain dito.
#8 all plumbing has to be exposed for inspection.
I know 5 # doesn't sound like much but If you don't close the openings right you could have a pressure release explosion and someone could get hurt.
You will also need a pump and test gauge hooked to the system.
I recomend you get a plumber to do this ( rough inspection)for you.
