The left most is a 2 inch wet vent, the middle will be a sink pump in the basement and the last is a shower. this is the 3 inch toilet drain.
I am prepared to switch them to wye fittings because i have read on their backs is no good. I copied from the original copper plumbing.
Also I will have 2 vents i will merge in to the 2 inch vent that exits the roof. the 1.5 shower and 1.5 sink pump, all exiting the same nail plate. should i use a double wye or is a double sani acceplable
thank you

I'm not sure about UPC but in Mass code it would have many code violations. San tees on their backs should be wye and 1/8s. 1 1/2" should be 2" for the shower. Vent for sewage ejector should exit the roof independly.
Not to be rude but I think you time and money would be better spent if you hired a plumber for this job.

The shower it 2 inch drain with 1.5 vent.
I will swap them all to wye since there is no room to fix the 2 inch wet vent
I found the section of the code that explains direction changes. im going to raise the 3 inch run and use the wye and 1/8 bend to join the shower and 2" vertical vent.
with that pipe raised i can use a vertical wye to drain the sink pump where this pipe meets the sewer pipe
The sink pump in the basement is for the auto flush on the steam unit. I cant tie it into the toilet and shower vent in the attic?

here the shower can tie into the 2" wet vent. it will not need to be individually vented if the trap is within 6 ft.

A double tee or cross will be fine for the vents in the attic, just be sure to invert the tee.

Thanks,
This branch is in the basement starts at the toilet then runs horizontal and makes a 90 into the iron sewer pipe.
I think i need a clean out in front of the toilet because it is a horizontal branch of the building drain and below the first floor correct? I would use a wye w/ 1/8 bend to hook up the toilet flange and a cleanout plug in the end
Here is what the code says
07.4 location. Each horizontal drainage pipe shall be
provided with a cleanout at its upper terminal, and each run
of piping, that is more than 100 feet (30 480 mm) in total
developed length, shall be provided with a cleanout for
each 100 feet (30 480 mm), or fraction thereof, in length of
such piping. An additional cleanout shall be provided in a
drainage line for each aggregate horizontal change of direc-
tion exceeding 135 degrees (2.36 rad).
Exceptions:
(1) Cleanouts shall be permitted to be omitted on a hori-
zontal drain line less than 5 feet (1524 mm) in length
unless such line is serving sinks or urinals.
(2) Cleanouts shall be permitted to be omitted on a hori-
zontal drainage pipe installed on a slope of 72 degrees
(1.26 rad) or less from the vertical angle (one-fifth
bend).
(3) Excepting the building drain and its horizontal
branches, a cleanout shall not be required on a pipe or
piping that is above the floor level of the lowest floor
of the building.
(4) An approved type of two-way cleanout fitting, installed
inside the building wall near the connection between
the building drain and the building sewer or installed
outside of a building at the lower end of a building
drain and extended to grade, shall be permitted to be
substituted for an upper terminal cleanout.
Thanks
