    Michigan is an IPC state.

    Just as important is exactly how each of the drain and vent connections are made. We would need to see your plan to verify if it were correct or not.

    I tried to figure out your plan there, but I'm not seeing it. We have to submit an isometric plumbing drawing as a precursor to obtaining a plumbing permit. It's easy to look at an isometric and see what the plan is.

    One fixture's drainage cannot flow past another fixture's drain connection unless it they are vented first.

    I see drains flowing downward, but no vent going up.

    From the point where a fixture's trap arm starts, there can be no more than 1/4" per foot of grade between the trap and it's vent.

    the vent going up and out is pic 2, it runs under floor area about a foot than straight up and out roof, its 3 inch pipe,
    so the 2 inch drains can not run into 3inch drain with out a vent first is what im doing wrong correct ?
    also the 3inch has just a little more than 1/4 inch drop ? will i have to fix that to a perfect 1/4inch drop as well? ( in the pic i have not connected the pipe yet)
    and as well my tub has a pee trap running under the floor truss ,is the ok?

    i will work on a drawing as i fig all this out for you .

    I am not trying to be crude, but you have a lot of studying to do.

    Before any drain can go down, it must have a vent going up. The distance allowed between drain and vent means that the pipe cannot drop more than 1/4" per foot between the trap and its vent. Vents must go up, they can never go down to make a connection.

    Your sink vent must go up vertically at least 42" above the floor before it can be turned horizontally to make a connection with a stack vent.

    The tub will not drain properly if you deepen the trap to go under the joist.




    Here is a good link with information to heed from Bert Polk, plumbing inspector.

    also the drawing is difficult to show how exactly a drain runs ,the tub drain runs 1/4 inch down all way to 3inch connection with p trap just so happens to have joist runnung though the center of it.(the trap has not been deepened)
    the toilet drain runs 1/4 inch drop all the way tell it hit's the vertical drop of one foot and than turns in with 1/4inch drop one foot over to vent stack wich runs up though roof.(that is how things were set up before i took it all out,and it worked ?

    Sorry, I know sometimes I wish it were easier, but it is all for good reason.
    What you have would be wrong regardless of who did it or when. The "vertical drop of one foot" breaks the vent, and will not pass.

    What you have assembled for the tub drain is not clear. The tub's waste and overflow assy must drain vertically into the trap; the trap cannot be further downstream.
