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...

I discovered a leak in my laundry closet, and on tearing the drywall discovered a crack in the tee in the vertical drain vent stack. The origin of the crack seems to not one but two drywall screws which the folks remodeling the bathroom (on the other side of the wall) for the previous owner...

Hi: I am changing my 2nd story tub from a LH to RH drain, so you don't have climb in between the toilet and the tub to turn on the shower. Originally all the plumbing was along one wall with lav, toilet and tub in a row. When I opened the walls, I was expecting to see vent stacks for all 3...

Any suggestions or comments are greatly appreciated! I attached images of the original configuration in case it was useful and a potential new plan. While renovating a second floor bathroom I am going to be swapping the location of the sink and stand up shower (and replacing the stand up...

Hello, I have made use of the professional advice goldmine on this forum many times in the past, but always by reading existing threads. With my latest plumbing project I figured it's time to post a thread of my own! I am firmly in the DIY class, and I would love advice from others out there...

I am adding a new master bathroom to my house and wanted some feedback on my diagram before I start gluing the drain and vent pipes together. I ran a new 3" drain to my basement and I am going to tie that into the main sewer drain. Then upstairs it goes to a 3" San tee directly to a 3" 90 to...

Sorry but I'm not familiar with "forum educate" never done this online stuff before. But anyways I'm looking for help on how to lay out the DWV and venting for a basement bath. My home came with a toilet (all by itself) in the basement. Cast hub 4" plus it was 2" vented as you can see in the...

Hi Folks, I'm a first time poster here, but I have been coming to the site for a couple of years now. My house (in Nebraska) came with a basin for the washing machine drain. See picture #1: That isn't terribly problematic, except that the basin empties into what seems to be a faulty floor...

I'm not a pro plumber, but I've come to respect your trade immensely as I've remodeled my 100 yr old home over the years. My current project involves turning a room that is not a bathroom into a bathroom. I've got ample attic space above the proposed bathroom, but finding a clear route up to...

Hi All, I have reviewed post already covering this issue but didn't get a solid answer from them so any further advice will be greatly appreciated. My problem is that I have a couple of 3" ABS combo's that have a very slow leak at one of the hubs. My project is a whole house under...

The house we are building will have a polished concrete slab on grade as the finished floor. The concrete guy asked if the underground drain and vent lines can be cut level at the top of the finished concrete floor before he places the concrete. He said he used to do this in another state and it...

I've often got questions or just curiosity on the means, methods, and materials used for every day, taken for granted, inner workings of buildings like the DWV systems used to evacuate our waste. I might even sketch out an idea once in a while just to see if it's at all plausible. My recent idea...

I'm about to install all of the rough-in plumbing for the above-slab drain and vent system for the first time and would like a "pre-inspection" by knowledgable pros. Don't assume I know something that's not shown or said, since I'm strictly DIY. Absolutely tell me about any code violations...

Hi, I'm a plumbing newbie/DIYer and I could use some help. I'm designing a small house for my Dad in Idaho and I'm trying to sort of the plumbing details. The house will be placed on a gradual hillside, has a full (walk-out) basement, a main floor and an liveable attic. From a plumbing...

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!

I have a utility sink in my basement that sits along a concrete wall with a footer. Since I can't run the vent stack within or directly against the wall, I ran the P-trap sideways with the vent stack running a few inches (about a hand's width) off the wall along the side of the sink. My...

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...

Hi all, I'm installing a new utility sink and relocating the washer. Working off of Terry's infamous Laundry Tray and Washer Rough-In diagram, I placed the washer and sink on separate walls. So my question: 1. Is it okay to turn the 2x2x2 long sani-T 90 degrees so it's horizontal rather than...

Hello. I am needing to tie in a new drain line coming from a new 2nd story bath as part of 2nd story addition project. The drain line from the 2nd story ends up in the crawl space and will meet the condition as shown in the photo. I have also drawn a simplified sketch showing what each line...
