Ill keep this as short as possible. First, its a DIY project. I have a permit. I am installing a new bathroom in an upstairs of a 75 year old house that previously had no plumbing upstairs. The floor joists are only 2x6 so there is very limited space for the 3" drain and no space to vent out of the pipe inside the joist area. I have installed a LVL beam that I will run the plumbing along for a horizontal run before it drops vertical to the crawlspace (right side of the photo). The problem is that I cannot get a vent on the main run from the closet flange as there is just no room without dropping the ceiling which is already only 7'2". I intend to box the LVL beam and create a bulkhead for the plumbing.
I have attached 2 photos. Please note this is just a quick mock up to show my question. In the photo that shows the drain, there will be a sink and a shower to the left upstream. Both of those will have additional vents in the proper locations, the vent I am showing in the photo is just the dry vent for the toilet. Is this acceptable to vent the toilet? The run from the closet flange to the wye is only 3 feet (yes it will slope properly).
Will this vent design work and pass the 2015 IRC code (what is used in my area of Michigan)
Also, I have included a photo of the 45 degree closet flange with an additional 45 on it to get from the flange to the pipe in the space I need. Is there any code reason that I cannot do this?
Thank you for your assistance.
