Current bathroom has a low ceiling height due to ducts and plumbing. I removed all the ducts but left with the toilet drain from above bathroom. Can this be moved closer to above subfloor? There’s a joist right in the way so not sure how to move this without impacting structural integrity.
1) The cast iron sanitary tee would need to be cut out and moved up (replaced with PVC). It looks like that galvanized steel pipe would need to be relocated too. Though if I was redoing the bath, I'd probably replace that galvanized pipe too as most galvanized is nearing the end of its useful life.
2) The joist needs to be cut out and re-structured. Usually adding another perpendicular joist 'header' will handle the load. Others will help with the details.
I am adding a water line for my new humidifier, and my plan is to tap the 3/4" hot from the water heater. I've been practicing my joints, and I feel comfortable enough to do it. I'm having a bit of trouble in that I expected more flex with the 3/4" line. I cut out a section about 3/4" to accommodate the tee. I'm able to move the pipe about an additional 1/4" comfortably. I'm not quite sure how much space I would need to insert the tee but I know I don't have enough space at the moment. I checked in the ceiling and this pipe goes to a 90 elbow. I'm not sure what is considered too much pressure, and if I can safely force it a bit more. My last resort plan is to use a Sharkbite slip joint fitting and get a plumber in to make a permanent connection. I'd like to avoid that if possible, but it's an option. Also, I am about 8" from the drywall. Is this a safe distance or should I get one of the fireproof mats to put back there? I've enclosed a picture so you can see.
By the way, I haven't cleaned or deburred anything yet. I will definitely do that before soldering.[img]https://cimg3.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/img_2525_04e0e6446e5deac518f5f4855dd9e94bf428ed16.jpg[/img]

I am considering putting a bathroom in the basement. When we built the house we payed to have the rough in done for a half bath. One thing I realized later on is they put this in the worst possible location as there is duct work right above where the toilet is. Anyhow I am just trying to understand which pipe is for what. I know the toilet flange is the 4 inch. I believe the one next to that is for venting, and the other is for the lavatory. My trouble is trying to understand how to do the venting. I have attached a picture of where I believe the vent from the master bathroom vents. The other picture is from the waste of the kitchen sink, I don’t see anywhere that vents. Do I run a horizontal pipe from the lavatory pipe to the vent and then the vent straight up and tie into the same vent as the master bathroom? Any advise is appreciated.
