Hi I'm remodeling a bathroom. (Doing the construction myself, but my plumber pulled his own permit and did that part of the work.) Pulled the tub and converted to shower, moved the drain to center. The drain stack is cast iron. Here is the pic of how the drains went into the stack before inspection. The plumber connected to the pvc arm that was already there, he did not build the two 45's where it enters the stack.
On the rough inspection, the inspector did not approve and noted that we have to "properly vent shower drain". I was there when the inspector came, the plumber was not. The inspector did say I could continue the work upstairs in the bathroom and gave me the ok to cover the walls and start my tile, and that the correction could be done in the basement and he would look for the correction on the final so that there wouldn't be a re-inspection fee. When the plumber came back he assumed the inspector's problem was with the cast iron stack head fitting and rebuilt it like this:
I like that the toilet enters the stack below the shower, but I'm not sure that fixed everything. The drain arm is 1-1/2" pvc and is about 5.5 feet long. Is there still an issue with venting due to the height of the trap weir and where the line enters the vent? I called the plumber and asked him this but he said he didn't understand how it could be a problem. I may have said it wrong to him, but I said I thought that the drain arm had to enter the vent at a correct height relative to the weir but he said he didn't get it. I then said I thought maybe another way of saying it is that the drain arm can't drop more than the pipe diameter and he said as long as it's a 1/4" per foot it wouldn't be a problem. I haven't called for final inspection yet. Help!
