Hi all,
I've just bought a house that has been gutted and needs new everything. I'm trying to do as much of the work myself as I can, and right now I'm making my plans for the building permit. I'm sure I'll have many questions, but right now I'm trying to figure out where my main DWV stack will go. The house has no DWV plumbing except some iron pipe where it exits the house to the septic tank, which includes an old standpipe style vent (see photo). My question is, do I need to continue my main vent stack straight up from this point, or can I run it horizontally (with proper slope, of course) to the middle of the house (about 12 feet) and run it straight up from there? I know I can run a drain pipe from the middle of the house, but my question is does there need to be a vent straight up from where the soil pipe exits to the septic? Thanks in advance for your help!
