vent stack

I have an improperly drained kitchen sink and utility sink situation that I am cleaning up (including permits and inspections). I think that my question is specific to Wisconsin plumbing code. To the best of my knowledge, section 905.5 of the UPC explicitly allows a design like shown below...

My old standard toilet was plumbed directly into my 4" cast iron soil stack, and I want to replace it with a hall hanging toilet. I've picked up a sigma duofix carrier for 2x4 walls from Geberit. The old toilet was wet vented. This is the only toilet in the house. It's is on the second floor...

My bathroom (house built in 2002) is on the top floor of the home (3 floors) and I was able to remove the existing bathtub and now I'm preparing to put in the Kohler Underscore 60x30 bathtub Of course with my luck there seems to be a problem. There is a black pipe (vent stack?) that is going...

Hello, if someone could answer a question for me I would really appreciate it. We are building an a-frame house that has a dormer off to one side with a shower and sauna in it. It would simplify things greatly if I could run the vent stack for all the 1st floor plumbing through this dormer roof...

I apologize in advance for my: babbling, crappy pix, complete lack of correct terminology and inability to comprehend basic plumbing principles!!! I will NEVER apologize for my independence, refusal to be ripped off ever again, or for the fact that I TRIED and sometimes I even sorta succeeded! I...

We currently have five plumbing vents through our roof. There are two 2" vents (toilets) and three 1.5" vents (sinks/tubs, washing machine). Before putting on a new roof I want to consolidate them all into one new 4" vent. The two existing 2" vents are furthest away from the new 4" vent, and...

After scouring the forum pages and reading all the great advice, I had my water softening company set up a stand pipe that drains into the clean out. The clean out is for a bathroom on the other side of the wall. It was the only option we had. Now I’m wondering if they were also supposed to put...

Greetings, Firstly I appreciate any and all professional advice that anyone here can provide. I read another thread on a similar topic a few weeks ago, and the original poster seemed to sustain an adversarial posture despite (and in spite of) the sound recommendations of the professionals on...

Hi Everyone. First time caller, long time listener! I've searched and haven't found a thread that answered this question: Bldg dept. is prohibiting us from connecting the lowest bathroom's local vent to the vent stack on that level, instead they need us to connect to the local vent or vent stack...

House ~1945, full basement and 2 stories. I am replacing a section of cast iron pipe (long story). The waste pipe descends from the 2nd floor to 1st floor (no connections) to the basement in the far left corner in the photo, which is no the corner of the house. In the photo, there is a wye...

First time posting here, so please bare with me. I am looking for advice on how to vent my upstairs bathroom that we're in the process of remodeling. The original venting design utilized a 1.5" drain from the lav as a wet vent. (pic. original plumbing 1) In this remodel we will be adding...

Hey guys, I’m building an extension at the back of my house, where I want to add a toilet. There is no sewage pipe there, however there’s a 4 inch PVC vent stack, going from the building drain directly to the roof, with nothing else connected to it. Is it possible to plug into the vent and use...

Hi all, I've learned so much by reading all the comments on this forum, but this is the first time posting a problem of my own! Looking forward to hearing some feedback, if you all have time during these crazy weeks! I'm remodeling my second floor bathroom (under NYC Plumbing Code, 2014 - ie...

Hi, this is what I just found behind a wall in my master bath. I am totally gutting this room, and am wondering if I can bump my main vent stack back about a foot to take advantage of all this wasted space in the wall behind it; I will be removing the small wall on the right of this picture for...

I'm doing a renovation and I'm installing a new sink. For some reason I can't wrap my head around how to properly vent the drain. I ripped open the wall behind the toilet and found two pipes, one I'm assuming is the toilet drain and the other, the vent. Which pipe do I drain the sink into? A...

We have replaced our main sewer line out to the street and are in the process of installing new plumbing to the 1st and 2nd floor bathrooms. The 1st and 2nd floor toilets are directly above one another and previously they both drain into the main vent stack which is directly behind them. The...

Hi Guys, I am planning on adding an addition bath/bedroom. The concrete guys need to know where I want the trench for the plumbing do be dug. Attached is a picture of existing house and proposed addition. the proposed plumbing waste lines are in orange. Could someone with experience please...

I own a 2 story townhome on a slab with no basement. Our downstairs bathroom has had a sewer smell develop in it and I also noticed the toilet was rocking side to side. I pulled it off to find a broken pvc closet flange. Replaced the flange and set it back on with a new thick wax ring with no...

Hello, me again....so I have replaced my old cast iron soil stack w/ PVC. The cast iron OD was 4 - 1/8" so I took Terry's advice and bought a Copper to Cast Mission Band. The problem that I am having is in order to get the PVC pipe that is inserted in the San-Tee below to fit under the 4" cast...

I recently discovered that the vent pipe from my kitchen sink and dishwasher is undersized. The contractor routed what looks like 1" pipe through the wall (presumably because there wasn't enough room to route 2" pipe), which then feeds into a 2" pipe that leaves the house. There is no...
