    Water Softener Backwash connect to sink drain

    Please see the photos. So my basement does not have any access to drain pipe. I had to bring the discharge to 1st floor bathroom as you see on the photo. I know the current connection is very wrong. So I was doing more research and tried to figure out what would be the right solution. I came...

    Which drain pipe to use?

    Hi all, I am adding a bathroom to my basement (it is already stubbed out for a shower, toilet, and vanity). However, where the vanity will go there are 2 DWV pipes next to each other, and I'm not sure which one I would need to drain the new sink to. Can I use either one? I'm sure there's a...

    Basement shower drain questions

    Hello all, I am putting a bathroom in my basement. Everything was plumbed in when I bought my house except for the shower drain. So it has been "my pleasure" to tear up the concrete to put in the drain. The main 3" drain wasn't exactly where I thought it was going to be, so it is going to...

    Hello, I am finally diving into utilizing the pex tubing in the slab for our basement versus the duct work from the forced air gas furnace. After finishing the basement last winter and spending more time down there this winter we would like to improve the comfort level during the heating...

    Basement washing machine vent question

    Hello, I am finishing my basement and have a question about how to vent a washer. I have a washer going in about 12 feet from the main soil stack (cast iron, goes into floor, not “hung”), which I had a plumber put in a place that I can connect to with 2” PVC a while ago. The stack has various...

    Can I re-route drain line outside through the yard then back inside?

    I'd like to remodel our basement, but the drain line is in a very inconvenient location. It runs from an addition (on the left side of the picture) through the original foundation along a very long wall that would require some creative framing or loss of space. Can the drain line be re-routed...

    Water softener and Neutralizer Drain Problem

    I have water softener and neutralizer on basement but I do not have any floor drain or access to main drain. (I mean I am sure it is in somewhere under slab but that would cost me too much to dig out the floor, etc.) Sump pit and pump is not an option for me. For now, previous owner, connected...

    Venting basement fixtures with limited options

    I am re-doing my basement plumbing. Currently, all these fixtures have their own AAV because there was no wall to run a vent. However, I was able to make one recently so I thought I would go ahead and try to vent these correctly. The only issue is that I will have to go horizontal to get there...

    When I turn on my Air Conditioner my laundry room drain smells.

    Hi everyone! First post here looking for some help! A couple years ago we had a sewer backup that left us with 3 feet of water in our basement. After that we had to replace our air conditioner and we started to smell sewer (the same smell from the flood) around our house. We thought it was the...

There is a toilet rough-in (3 inch PVC) which looks good, with 12.5 inch from back wall, 15.5 inches from side...

    Adding Washing Machine Standpipe in Basement

    Right now, my washing machine in the basement drains into one of those very old, super-heavy concrete utility sinks. The sink is starting to crack and leaking more often, it often clogs with the lint from the washer, and we're tired of switching out the mesh sock covers. I want to put in a...
