I am renovating the basement bathroom. Started as replace the shower, but some water damage made it a complete tearout. I am at the point to cover the shower and toilet plumbing, but am a bit concerned. 1. The shower drains into the toilet line, right below the toilet. 2. The shower drain has...

I am having to re-plumb my bathroom, and am trying to follow IPC 2018 as best I can (I live in Vermont). The current Stack Vent, which exits the roof, is 3" copper and currently only vents the toilet. As I am now replacing the toilet, and remodeling the bathroom, I figured it was a good time to...

I'm adding a DWV system to a basement and need to tap into a 3 in dry vent stack that currently serves a 1st floor bathroom with toilet, tub and lav. As you can see, there's not much room here. The 1st solution that comes to mind is to add a 3x3x1.5 santee above the existing. This involves...

Can anyone provide an example (or multiple) of how IPC Section 917 can be used in a residential setting for a two-story home with stacked bathrooms (shower, WC, lav)? I'm particularly interested in how that section allows toilets to use the same stack (if at all). I'm having trouble...

Hello plumber folk. I am finally getting fixtures in (started a remodel which became a teardown. My buddy, a retired plumbing inspector gave me the plumbing design and you fine people helped me make it a reality (I passed the rough on the first go). Due to lots of things I have a stack for the...

I found this done. I thought sinks could not enter below the laundry in the stack? Also, couldnt you use a double sanitee and eliminate the sink revent altogether? I’m sure this is an easy question for the plumbers. But I can’t seem to find these answers anywhere. I’m getting ready to put in a...

Hi all! I am planning on installing a bathroom in my basement, I live in Maine (IPC code, I think). I have easy access to the main stack to the septic system but venting the drains (and up flush toilet) is going to be difficult. After hours of research I am totally lost on when wet venting is...

Hello everyone, I am doing a remodel and have tied my new bath drain into a conveniently placed existing vent. Based on my research I thought it would be okay in this circumstance but am now questioning the setup and looking for a second or third opinion. The new bath drain ties into the...

Hello, I'm putting in a bathroom sink drain in Canada, Ontario. We had a plumber come in who told us there was no vent for this drain and it would cost a lot to install. We contacted another plumber, who said all we needed to do was install an AAV. I'm a little confused because it looks like...

Hi, I have a restricted trap below my laundry standpipe that can no longer handle the spin cycle output of my washing machine. It is the original installation from 1962; a 2" cast iron pipe goes below the concrete floor to a buried trap. Several times over the last 15 years I was able to...

I'm venting a bathroom group (sink, toilet, bath/shower) and the rough in location ended up placed directly below a truss, which means I can't take the 2" vent directly up and out. I'm working with a 2x4 stud wall and need to bore through several and make a turn to avoid the truss. Is it...

I am hoping that I can get some advice... New addition to the first floor; relocating the bathroom and adding a shower. In the end, a bathroom group (5 DFU) and a utility sink (2 DFU) will be vented. I want to route the vent to the attic and tie in up there, but I am not sure that I can. The...

Greetings, I’m pretty sure this vent system is to code but, I’m a rookie and still learning ALOT so I figured I’d throw it out there and see if anyone sees something wrong? - It’s for 2 bathroom sinks, 2 toilets, 1 shower, 1 washing machine and a 1 kitchen sink. - All the branches are sloped...
