Thanks to all those who've helped me over the last while with my questions. I went with ABS pipe for my basement bath rough in and now need some help as regards venting same. I've taken a photo of the drain layout to let you guys see whats what.
I'm glad to announce that I now have no leaks where I joined the ABS to the CI My Questions
1) There was an old 2" drain from the old sink into the 4" CI (where the ?#1 is),can I just plug this or does this new 4" section need to be vented, and if so is this 2" sufficient?
2) I can vent the bath/tub pretty easily into the main vent but the sink is on the opposite side of the room. I'm assuming I need to vent the sink also, but other than running a vent across the ceiling to the main vent stack do I have any other options? Read about AAV?
3) I've used a 2" wye to join the sink and tub lines but should i be using use a san t ?
Thanks for taking the time to look
