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.
