Hello all, I have been lurking here a while and have gathered lots of info. I have also managed to get the pluming in my 80 year old house draining better! I am finally starting work on a new laundry room and what is to be the first stage of a full replumb of the house. When I do the kitchen and bath remodel I will replace all drain lines and revent the entire system with PVC. For now I just want to tie into the existing iron stack.
What I have is 4 or 5†cast entering the front of the house 8†above the basement floor. There is a large clean out there. At 24†there is a 1.5†threaded hole in the side (I added a 2†trap and washer pipe directly to this with a reducing ring.) The cast then continues vertically to 5.5 ft and turns to the back of the house where the kitchen and bath are. The kitchen is yet to have a vent added but the main stack has 4†vent next to the toilet. The tub and bathroom sink share an AAV.
I am adding a new laundry room upstairs in an area of the house with a crawl space. There will be a sink on one side of the room and a washer on the other. I will run the 1.5â€vents for both up to the celling and join them to the new main stack vent (16 ft away) when it is installed, for now I may use an AAV on them. The 2â€pipe in the floor will drain from the sink to the washer area and turn towards the basement 13 ft away. At the basement I will drop at a 45 towards the 1.5†hole in the main stack 5 ft away and 5 ft down or so. Into this same hole I want to plum a utility sink and a small stand pipe for AC condensate pump and water softener discharge tube, no washer down there!
My thought for the basement part was 1.5†threaded to male 2†PVC adapter assembly. To this I put a vertical Y to the upstairs laundry, then a horizontal Y to the utility sink, then another horizontal Y to the trap and stand pipe for the pump discharge. This gives me a clean out for the short run to the stack. Do I need an AAV/vent some where in there too? This is rural WI so I can wet vent (like the stand pipe is now). When I redo the stack I will replace the 1.5†fitting with a 4â€T with a 2†fitting on the side and run a vent line to the main vent if needed.
I don't like the 1.5†at the end but I am not ready to do the main stack yet. (can't afford that good toilet Terry likes yet and its too cold on the roof for working on the new vent exit.) It is the part in the basement I am most concerned with.
Thank you for your input!
