Hi everyone,
Let me start by saying again that this forum is awesome – we all sure do appreciate professional plumbers taking the time to help us out. Thank you Terry and everyone else here!
I am now remodeling my mechanical/laundry room and I am trying to accomplish several things with the plumbing. I attached a photo of the room.
Currently in my new home, there is a 2” drain in the basement going under grade to an unknown sized pipe (3” or 4” I hope) with a 1.5” vent to the roof with nothing draining or venting above it. There is a laundry sink with a laundry washer dumping into it along with 2 water softener drain lines (looks like an illegal air gap to me?). Also does the sanitary T look like it’s upside down? I want to tear all this out anyway.
So my goals are to do the following with the 2” drain if it possible with very limited space to work with
Install a separate laundry standpipe behind the washer – I cannot dump into the sink because I want to install front loader machines with a counter on top and a drop in laundry sink
Install a new standpipe behind the softener with appropriate air gap, trap, etc.
I found an image from Terry Love of splitting a drain and I modified it with what I want to do, are my modifications/plan legitimate or code violations? And thank you Terry, I modified your image only to get my plan across. Note the image is for mock up and it should be flipped like a mirror image to fit my photos
I have studied the plumbing code for MN, but it is really complex to me – much harder than the NEC, which was my trade for awhile, so I appreciate the help. I have read that wet venting is not code in some states, it appears to be in MN, and I attached the code reference if anyone can verify that I am reading it correctly because I am not skilled enough to comprehend if what they are saying is acceptable to what I want to do here.
Also do I need to incorporate a clean out somewhere? My issue is that I have no room to place the Wye above the current clean out and still drain the sink, or at least I don’t think I do, so I was going to cut 2” pipe just below the cleanout. I was thinking if it’s ok, to place a cleanout on one of the vertical drains with an access panel above the sink when I finish the wall.
Oh ya, one last minute thing, I just noticed that MN code says that indirect waste piping (803.1) between 5-15' need trapped but not vented - does this mean I do not need to vent my softener standpipe?
Thanks everyone!
