I have this existing cast iron drain pipe.
I'm replacing it with PVC. I don't like that it's a tee fitting because that makes it difficult to snake as it can go from one side to the other.
If I put a double wye here, then I might have a siphoning problem because the trap weir will likely be higher than the vent.
Can I put one sanitary tee right above another? My thought was to put a sanitary tee in (3x3x1.5) for the washing machine. Then right below that, I would put another sanitary tee in for the bathroom sink. I have the ability to raise the drain pipe for the washing machine, so that shouldn't be a problem. Seems like it would be a good middle ground. I wouldn't have to worry about the issue with snaking like I do now and no siphoning issue with a double wye.
Thanks in advance.
