Do I need to change this santee to a wye?

[chimmer]

Further to my other threads I was wondering if it will be okay to use this 4x4x3 santee to tie in the main floor plumbing. I think it is technically supposed to be a wye based on what I have read since the vertical section above is draining a 4 piece bathroom before it vents to the roof. I used a santee because it allowed for the slope I would need to redirect the main floor plumbing with a 3" line (about 8 feet, so down 2 inches).

If this fitting will cause a problem, then I guess I can change it to a 4" wye and use 4" pipe so that the slope only needs to be 1/8" per foot but of course I would prefer not to change it if not necessary.

(The silver bubble wrap insulation is there in an attempt to deaden the sound of water rushing through the pipe and the cleanout fitting is there temporarily)

Whether you use a tee or a "Y" is a personal decision, because there is no requirement, in this case, for either one.

If you ever have to snake it, buy a cheap male by hub adapter and screw it in, this will save your threads. most plumbers wont give a shit about saving the threads
