basement

Hello, I an a DIY'er who is embarking on a plumbing journey. Basement is stubbed in for a full bath and that is what I'm attempting to install. I have skills & tools but lack the years of experience this forum can provide. This will be my first attempt to attach to roughed in plumbing. Some...

Hello and good day to all of you. First of all thanks for taking the time to read this post! I am a DYI enthusiast and currently working on a kitchen sink + laundry plumbing and I have the sink drain connected to the laundry drain, is this allowed? I planned to connect the laundry drain to...

Hey All, New to this, and I was hoping for some help. I am new to wet venting and I am looking to rearrange some things in the basement washroom, but due to its location, venting is going to be tough, so I was hoping I could wet vent this. The picture is birds-eye view, I am looking into...

Dear all, I'm looking for advice on order of operations for a basement remodel. The picture below is what the current setup looks like for plumbing. On the left-hand side is the main sewer stack. Next to it is a washer drain. I can see rough-in's for a toilet, shower, and vent but they're all...

Hello, I've read through many similar threads of people trying to connect to existing soil/vent stacks in their basement, and as plumbing seems to go... everything is a one off. Our house is in Seattle and built in 1926, floor plan is a four square. The basement is unfinished, just has rough...

Hi all, I am designing my DWV for basement bathroom and bar sink/powder room. I'm hoping to apply for permits within the next 2 weeks. We are under 2021 UPC and 2021 IBC. In the bar sink and powder room area, I am trying to figure out how to place my upper terminal cleanout to keep a clean...

Hello! I'm a DIYer planning out our basement remodel. I'm trying to get everything all laid out before filing for permits. Location is Spokane County, WA. Code is UPC. I'm currently working on the DWV layout. I am trying to figure out the best layout for the drain system. It will all be...

I’m adding a shower drain to the basement, tying into the 4 inch main. Which layout is better (if any)? I’m running out of room below the slab for the vent line—stack up is too much. Option 2 gives more room to re-pour the concrete, but is the P-trap below the 4 inch main OK? Option 1 is...

Thank you everyone in advance. I’ve been researching this topic for awhile and have been going in circles. Here is the background: 1. Climate Zone 5A 2. Basement is all concrete block with about 18-24” above grade. 3. 1997 construction, not sure if the block is treated with any repellent, almost...

Hi all, trying to finish my basement and have the following question (forgive the crappy drawing). I have existing plumbing rough-ins for a shower, toilet, and a sink. I would like to add a sink and/or washer marked in maroon (bottom right). The the green upward arrows are vents for the existing...

I have broken up the concrete in my basement for a new bathroom. There are drains that have been roughed in by the builder, but the layout won't work for us so I'm going to rearrange. Hopefully the picture can give an idea of which way the drains are going. I've attached a picture showing the...

I believe they go to the second floor kitchen and bathroom. I am looking to buy this home. I usually fix things myself. Is there any tests to perform?

My home is from the early 1900's and I have a large main drain that is cast iron. The drains that run to that main one are the kitchen sink, the basement shower, upstairs shower, laundry and upstairs bathroom. The picture is of the grease trap drain that the kitchen sink runs to. Now I moved...

Hi all! I am not a professional. I work in an office building that has had mold problems in the past which resulted in coworkers becoming ill. There was testing done that confirmed mold present and recommended installing sump pumps and a dehumidifier in the basement. This is what it looks like...

Hello All, Looking for comments on my strategy to insulate the basement in my split foyer home built in the 1960s. Walk out on the back side with partially buried walls on the front and sides (graded up the side walls to about 3 foot buried walls in the front) living in zone 4A (we get all four...

Hi all, I've read the numerous discussions about installing basement subfloors, and have especially appreciated the advice in the other threads provided by Dana. I have extremely limited headroom in my basement so I have decided on the following for the subfloor: a) 6 mil poly on slab, seams...

I'm adding a basement bathroom, and wondering what's the best practice - to put new pipe runs in concrete under partition walls or next to them. It seems like for stubbing up, it would be better to have the run under the wall so that you don't need to have a 45 or other bend to get the pipe over...
