wet vent

Hi. Noobie here and thanks for the add! I'm a DIYer and want to add a shower to the half bath in basement. Not sure how to add drain line and vent. Please see pic attached. Red arrows show toilet and sink drain direction under slab. The blue circle shows where the copper vent meets slab...

Hello all, In the process of a remodel and I'm trying to wrap my head around how to vent the shower. The way I see it, I have two options based on where everything needs to be. Option A (red lines are my proposed runs): Option B: The shower trap will be too close to the wall to fork off of...

Hello, I am renovating my home by adding back-to-back bathrooms on the second floor. I have asked a plumber to do the plumbing. He came one afternoon and then he disappeared (after the first payment), and now I cannot find him :( . I am thinking to finish the job myself but I am worrying that he...

I am in the process of adding a washer and dryer on the second floor of my two story home. They will be located on the other side of the wall from a bathroom group (tub/shower, toilet, and lavatory) so I have relatively good access for routing the drains and supply lines. My question is what is...

We are currently undergoing a master bath remodel, and want to confirm my plan for venting the new freestanding tub. The previous bathroom configuration had a corner whirlpool tub framed to abut a single vanity along each side, and the tub drain was wet vented to the lav in the vanity along the...

Hello All, I am designing and will soon be working on a home Re-Drain Project. - Located in Tampa FL. - Code is 2020 Florida Building Code, so IBC / IPC 2020. - Re Drain project is adding a new main sanitary line outside of house to minimize trenching inside. - All PVC for new work. Looking...

Just had this amazing stack: Replaced with this somewhat less amazing version: I guess I have 3 questions: The new setup now has the lav (kitchen) wet(?) venting into the drain line for lavs 1 & 2 on level 2. From reading it seems like that's not per code, is it? (I think Indiana is...

Hi Everyone, I'm remodeling my old house and am not a plumber. I've read on the forums and tried to make sense of the code check book. Of all the trades I've had to do during this remodel - plumbing is the hardest and I have lots of respect for the problems that plumbing professionals solve...

Suppose a shower and a sink are the only two fixtures connected to a vertical 2" pipe that serves as both drain and vent. The sink trap arm attaches to the 2" pipe above the shower trap arm, so the section between the two inflows is technically a wet vent section. According to 908.1.1 (size)...

Hi I'm in California, and Sec. 905.2 says that a vent pipe connecting to a horizontal waste pipe must have its entry point above the centerline of the waste pipe. However.. there's no such requirement for a connecting waste pipe. So, what if the connecting pipe is a wet vent? If it's...

Hello, This is an update/new question from my last post. My home has old all copper DWV from 1960 and earlier, with even older cast iron at basement level-down, that I'm replacing with PVC. Plumbing noise isn't an issue; I really don't want to do expensive cast. The current copper has pinholing...

Hi, I am relatively new to plumbing, and I am simply wondering it the design in the picture below is acceptable in terms of venting and wet venting? I am renovating an old basement half bathroom. The drain for the sink is already taken care of, but I am just not sure about the drainage and...

Hi all, hope everything is going well. This is in WA state. I am adding a 9' x 3' full bathroom and stacked washer/dryer to a finished space above the garage. I have attached the layout of the space and my proposed plan for waste lines and vents. Is the venting I have adequate (or...

Two questions. If I’m using 3” for toilet run and 3” vent run, what is the longest run trap to vent for that toilet? 2nd question. Can a lavatory 2.5” run into the 3” toilet run before it connects to wet vent? I have tried to outline this in the diagram. Appreciate all the help, this has me...

Hey everyone, thanks for taking a look at my remodel and specifically toilet plumbing/ wet vent questions. The main questions are: 1. Can I: A. use a 3x3x3x3 wye with a toilet/WC on one side and a tub/shower combo on the other. I understand that the toilet should be the furthest from the vent...

Hey everyone, I'm at the plumbing stage of my DIY master bathroom remodel. I have some questions/concerns with how I've organized the layout for the fixtures. The information is in the pictures below. For reference, I live in North Carolina which I believe follows the IPC. I'd prefer to...

I'm planning on tacking a bathroom remodel and would like some pro advice as to whether this is up to snuff or not. I've never done wet venting before, but apparently that is what used to be in the bathroom and I'm planning on slightly modifying. Originally there was a double vanity (on the...

Long time reader, first time poster. I'm converting a small upstairs bedroom to a small bathroom. The layout is pretty standard as seen in my hand draw masterpiece below. The toilet and sink are to the right of the entry, there will be a clawfoot tub to the left. What makes this build unique is...

I am grateful for your consideration. Is configuration A or B compliant with the UPC? I'm pretty sure A is but have doubts on B. If both are compliant, which would you prefer? Thanks!

Hello, I have a 1952 cast iron drain setup for a hall bath that uses a wet vent from the lavatory for the tub. In the picture below, you can see that the lav drain runs about 3ft back towards the tub then turns back into the 2" drain that is running from the tub. The cast iron is failing and...
