Hi guys!
This is my first post, I've been lurking around the forum for some time as I've been planning my bathroom remodel. Some background info on the project: I'm turning a closet that was adjacent to my 1/2 bath into a shower. Built in the late 60's, the house is a 1 story ranch on a slab. There are two toilets, two sinks, and an existing shower all upstream of where I tapped into the main drain for the shower. I'm going to need to install a vent between the shower P-trap and the main drain connection so the shower P-trap does not get sucked dry whenever I flush the toilet. My questions are:
1) Will a 1.5" vent pipe for the shower be sufficient, or should I match the 2" drain that I have for the shower drain?
2) When I run the vent pipe up through the wet wall, what is the best way to support the cast iron vent stack I want to tie into?
3) I'm going to have to angle the shower vent underground so I can get it to come up through the wet wall, are there any limits on how tight the angles for the vent pipes can be? I've seen diagrams for loop vent on kitchen islands that are pretty convoluted, so I assume a couple 45 degree turns should be fine.
Attached are pictures of the shower drain with covered stub outs for the the vent and the shower drain, as well as the wall in which I'm going to need to run the vent.
