So wife and I tore down some non-load-bearing walls to create a mudroom and we're moving our washing machine about 8feet away. I can't use the current drain because of all the joists and vents in the way. I will be adding a 3x3x2 wye into the current 3in line. Issue is....the washer will initially drain the opposite direction of water flow before it gets to the 3in line.

Am I allowed to run my drain such that it follows parallel to the 3in line and makes a 180degree turn with a street 45 to a long sweep street 90 into the wye to finally go the right direction? It is a 2in drain for washing machine and these are all DWV fittings. Also, I was going to toy with rolling the wye so it's not completely on its side. It seems since it's a washer drain there won't be much in the way of solids going thru it and can't be too much of a clog concern?...but maybe I'm wrong. Tis why I'm here. Thanks in advance.

Code says every change in direction in excess of 135 degrees requires a cleanout on main floor or below.
The normal way we see what you are trying to do is: Street 45 into the wye, then the long sweep 90, but your layout looks ok if that will work in your circumstances.

Thanks breplum.

Regarding the cleanout...if I add a 2" cleanout in that line do I have to orient the opening so the cap/access is pointed straight out or upward? My issue with a cleanout there is I won't be able to access it from above once the floor is reinstalled, only from the basement can I see those pipes once the flooring is back in place. Refer to my most recent photo for actual run of 2" pipe and a location of the potential cleanout colored w/red, it will all be visible from my basement which is down in that opening under the 3in pipe. I'm basically on top of the basement cinder block wall where I'm standing.

Also, from what I understand, there must be a minimum of 12" clearance to access the cleanout on a 2" pipe and since it's between joists and next to a 3in line that may be near impossible. I'm assuming your recommendation will be find another way to run the line, LOL....ugh....

Some codes will let you omit a clean out if you use a long sweep. You still need clean outs every X number of feet but can use a long sweep at change of direction

Functionally, it looks too cramped to use the cleanout in that joist area, as your good illustrations show.
I would definitely use a cleanout on your laundry drain at the wall (behind the washing machine). Or if you dare, you could put the cleanout higher than the machine, so you don't have to remove equipment to snake it out in the future.
That is a great place for a cleanout but we rarely do it that way (aesthetics).
BTW, what app did you use to draw the colored lines?
