There is always a way to do it right.
Sometimes you just look at it until you figure out the way.
I installed a sanitary tee on its back.... why? because the pieces i was cutting out and replacing (had to move the drain) were installed the same way..
it is a shower drain., 2"., you see a 3" drain further back for the toilet.
water drains from right to left., the vertical part of the san tee is for venting...
someone suggested that using the san tee on its back is illegal... but there is no way i can fit a wye in there... thoughts?
If that is a vent it is flat vented and that is a no no...
If it is not a vent then the T should not be there...
the top is for vent., so yes it is flat vented for about 2' and then goes into a vertical vent...
any suggestions as to what can be done?
the main vent that goes up into the attic is on the right side of the shower drain... the drains exit downwards on the left side of the room...
prior to the bathremodel... which included breaking the wall between the closet and bath... the shower(tub) and toilet drain were to the right side of the vertical vents... there isnt enough room to move things around and i cant cut the floor joists
Rework the shower drain line so that it connects at the point where your vent transitions from horizontal to vertical. In other words, move the connection point the 2 ft. to the right that you mention. There, you'll be able to use a Tee, and be rid of the flat vent. I had to do basically the same thing cleaning up the inspected work of a plumber used by the previous owner of my house.
Maybe more pics are needed....
Can't move it to right
I'll post later today
will have to take better pics tomorrow., ill be back
it looks like it is a lttle late to change anything...
without cutting out the whole thing and starting over.
Technically it is not right but will probably work like
its predecessor did.....
It would have been easy before you put everything together so tightly. The Y on its back with a street 1/8 bend turned horizontal would have been easier to use. But there may be a more pressing problem if that fitting just visible to the right of the tee is also rising before it gets to the trap. IF so then it is creating a 3/4 "S" trap and that is more illegal, and a bigger problem, than the san tee on its back.
HJ is right. I didn't even notice that. Move your wye and 1/8 bend on the 3" down closer to the shower drain and rotate it up. Put your vent tee in and run your P trap directly to it. Then you just have to figure out the vent connection to the old vent line.
does a vent have to be after the p-trap?
can i have (from right to left)., vent., 90 deg elbow., tee or wye., conncted to p-trap., then continues ....
here is a sketch of whats been done., there are approx 5"-9" between the borrom of the floor joist and the ceiling (below)

in mine., the P trap is connected to a 1/8 bend down., then a straight., then a 1/8 to correct the prior down and tilt it towards the waste... which then connects to the tee....
do i need to post better pics?
That is why I called it a 3/4 "S" trap because it goes at a 45 instead of down, but it is still an "S" trap, and it is still illegal and a bad idea even if it were not. Your top drawing is the correct and best way, BUT the trap has to go directly to the vent without turning down. Once it passes the vent you can turn it anyway you want to.
