First time posting here at this forum, but have been lurking for awhile. I'm in the middle of a bathroom remodel, and have come to the point for rough in of DWV. My question is in regards to moving a toilet and whether it will need venting, and venting/connecting the shower drain to the stack. The bathroom is on the main floor of a ranch, which has a basement. So I have full access to the stack both above and below the bathroom.
The toilet will be moved 42" to the right from its previous location, which is 30" to the right of the stack/vent. Due to this increased distance from the toilet flange to the stack, I'm wondering if the horizontal run needs to be vented? I've never seen a toilet drain vented, but was wondering if this was needed... I know that I need to keep the pitch in mind from the drain elbow to the stack. I plan on rebuilding the stack from where it come out of the basement floor to the vent in the attic, so I could put in a couple 45s to move the stack closer to the toilet. There happens to be a supporting beam between the stack and the toilet new location. So I have a few obstacles to avoid.
My other question is about the shower drain/venting. I think I'm pretty sure how to handle this, but am looking for confirmation. The shower drain is approx 4 ft. from the stack/vent. I'm planning on wying into the 2" drain right after the p trap, (does it matter how far downstream from the p trap) and route that to the stack upstairs for venting at a level above the sinks on the main floor. But I'm not sure if it matters which drain connects to the stack first, meaning top to bottom. Does the toilet wye into the stack and then the drains from the shower and sinks? Or the other way around?
Any comments/suggestions would be great. If photo are needed to understand my questions, let me know..
