Hi guys, thanks for taking the time to look at this, I've been lurking this forum forever and have learned a lot but I have some very elementary plumbing questions to clarify before knocking this next project out.
I'm looking at adding a laundry room upstairs and a kitchen sink in the basement below. I have a couple questions as its been a decade or so since I've done much plumbing. Luckily I have an existing 2" vent pipe which should support roughly a 20 or 24 fixture load IIRC. My concerns, however, are with my layout. Am I overlooking something dumb?
1. I'm pretty sure I need to add a vent to the laundry room sink...right? If so, I'll just tie in above with the other new vent.
2. Is the basement kitchen sink (below the washing machine) at risk for having the p-trap siphoned or will it be ok as a "wet vent", sharing the laundry room drains as a vent?
3. If I need to make a horizontal run of about 6 feet with the 2" washing machine drain line, do I need to fir the wall out to 2x6's? It seems like cutting a hole for 2" piping through 4 studs will be too much structural compromise...... Am I overthinking this?
Orange is proposed new install, green is existing 2" vent pipe
