Hello all,
I've recently moved my mother into a studio space above our garage, but it's in a mostly unfinished state. Our biggest priority is getting drainage setup since her septic tank is finally going in the ground, so she can actually have a toilet. I'm doing the work myself to save money, but my plumbing experience is pretty limited. At this point, I've read through some of the IPC code, and watched a ton of youtube videos. I found this tool online to illustrate what I'm going for and laid out the critical components, minus the venting.
In the attached image, and the link you can follow to view in 3D HERE, I've laid out the main fixtures from left to right, a 30x60 tub (I was unsure how to model this in CraftyAmigo, so it's just a P trap), a toilet, single sink lav, washing machine, then kitchen sink and dishwasher, that then runs downstairs to a 4" pipe that will be connected to the septic. The exterior walls are represented in solid panels, and the interior walls are represented by the blue colored framing. The actual framing looks much better in reality than my hacked together 3D plan. All the dimensions are inaccurate but the total run of the back wall is around 28 ft.
I guess the venting is my biggest question. Previously I had laid out the venting to be a 2" wet vent that came up from the tub drain, with the addition of a 3" vent through the roof per code for our cold climate. Initially I had planned to run the vent from the corner to the left of the toilet where I currently have a cleanout, but I figured it'd be easier to go through the roof closer to the interior wall at the tub P trap since I'll have more clearance in the attic to work, as opposed to near the eave. I wanted to wet vent based on a video I watched by Rising Tide Plumbing on youtube, and to save money on the extra materials, but after sending it to a plumber through the website JustAnswer, I got a pretty rude shutdown and little actual information.
Anyway the long and short of it is, I want to run as little venting as needed through the interior wall if possible. Would my wet vent from the tub area be enough to cover the rest of the drainage? Or should I just run a 3" vent from the corner by the toilet? Hopefully this makes sense. Thanks for your time!
