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...

Hi all - longtime lurker but first time poster. I am redoing my bathroom and trying to set up a plan for the DWV lines for a standing shower and stackable washer-dryer, which are side by side (30" wide each, with a 5" framed wall dividing them). I am unsure how to properly lay out the vent...

In my area I can only find ASTM F-628 Foam core pipe, not ASTM D-2661 solid ABS pipe. Given that, what material can I use for roof penetrations, that will hold up in the sun? I see a lot of roofs with ASTM F-628 foam core pipe vents, where after a few years the vent look chalky and sun damaged...

I have a 1.5" galvanized plumbing vent that comes up out of a wall.... yet there's nothing obviously below it. The other vents all match up to fixtures below... this one not so much. This is a 1926 home, two story, stucco, lathe and plaster. How can I determine where it goes, and if it's...

we decided to DIY our plumbing in our new addition. We had a little experience but nothing prepared us for this big a task. We are getting ready for the rough-in inspection and capping all the drains and flanges. We put this sanitary tee with cleanout at the bottom of the waste stack where it...

I recently bought a house built with all of the plumbing in the slab and did a whole remodel. It was a bank owned property built in the 50s, and needless to say I ran into quite a few head scratchers. As far as plumbing, I replaced all fixtures and traps. In doing so, I noticed that the only...

*Storytime* :D For my family; I manage a 38-acre, private, saltwater lake property on the Intercoast of Texas with fishing & camping for a membership fee. Except, people don't want to come camping because we don't have a proper 'Bath House' just an accessible 1/2-bath restroom. I looked into...

Hello! So I moved into a house with a closet that used to be a laundry room. Back wall of the closet has a hole in the sheetrock where the washing machine outlet box used to be. In that hole: a capped DWV (and I assume supply lines, but I haven't opened the wall). I'm doing work in this wall...
