I am adding a bathroom in my basement. I have searched and read quite a bit of postings in the plumbing section of this website and came up with a plan on how to proceed. I have a few questions and also would like to present my ideas I came up with after reading old postings and have someone tell me if my ideas are going to work and/or if I should do something different. I have attached an AutoCAD drawing to help illustrate my ideas. The numbers in the drawing ‘Proposed Layout’, 1-6, represent the various visible parts of the sewer system in my basement. 1. Clean Out 2. Main Stack, everything upstairs drains into this stack except the kitchen sink. 3. Stack in which the upstairs kitchen sink drains. 4. Stack which utility sink in the basement drains, then goes by #2 (not connected) and goes up into a wet wall for the upstairs bathroom and makes a vent loop for the bathroom fixtures. 5. Cast iron floor drain. 6. Cast iron floor drain.
SIDE NOTE: The drawing is to scale, however the location of the shower drain is not exact, but is close enough for what I am trying to figure out.
Questions
1. By looking at the file ‘Proposed Layout’, is it safe to assume the sewer line runs in the side of my house by the cleanout (#1) then goes directly over to #2, then to #3 and #4?
2. I examined #5 (floor drain) and it seems to angle back to main stack, #2. Does this seem to make sense? At first I thought it would go back directly to #4, but after feeling around the bottom of the drain with a coat hanger, it seemed the trap angled back to #2. The green line connecting #5 to #2 is the path I believe the drain takes.
3. The floor drain is a 3” drain, can I tie into this drain for my bathroom fixtures?
4. If I can tie into the 3” floor drain branch, does the layout seen in the file ‘Proposed Layout’ seem to be a good layout? Is everything vented properly? If this isn’t a good layout, could you please sketch me one that make more sense?
5. If I can tie into the 3” floor drain, would the proper way be to use a hubbed 3” wye and add short pieces of 3” pvc and then connect to the cast iron floor drain with hubless band clamps?
6. Currently there is a utility sink which drains into #4. #4 Then travels up to the ceiling and over goes over by (not connected) #2 and then up into the upstairs bathroom wet wall and makes a vent loop, connecting up with other vents and ties into the main vent stack. In other words, above the utility sink drain, #4 is a complete dry vent which eventually gets to the main vent stack. Now the question. Can I move the utility sink from #4 over to #2, tying the drain into #2, and venting the utility sink and new bathroom through the vent the utility sink used to use (#4)?
7. Should I use a 3” or 4” flange and closet bend for the toilet?
