Basement Bathroom HELP

[pipehandyman]

Hi everyone, Im very handy but not so knowledgable with plumbing as an expert might be. im trying to add a bathroom to my basement and I am not sure if there is any particular order for sewage (toilet before or after sink and tub) within the line and also am not sure if I can tap into an existing possible air vent in the ground and existing connection

ALSO there seems to be a "Wye" adaptor which Im curious to know if I can tap into or if that would be a "no, no"

If anyone could help my figure out a correct schematic for running the Toilet, Sink & Tub I would greatly appreciate it as Im scared to start this job until I have a set game plan.

I attached some images showing whats going on in the space.
and two possible Layouts Im hoping to accomplish


thanks for any help

Thanks Frodo, I converted the files so they should just appear. didn't think about that before.
so I have two options Attached im considering. the empty space at the bottom across from the washer may be intended for a closet but can be utilized as part of the bathroom if thats the only way to get the pipes to work out...

I appreciate any help I can get, this is my first home with my wife and although we have been trying to do most of the work ourselves Id just like to make sure everything runs right and is to code so I don't get in too much trouble down the line.

thanks again in advance

I've read Vent pipe for sinks must be above the level of the sink trap.. I was curious to know, If I place a sink across from the existing Laundry Sink, if I am able to use the same vent pipe (laundry sink) running the (new)sink sewage line underground if that makes any sense?
I want to avoid, if possible, the addition of a new vent pipe that might have to run round the ceiling of the room in order to connect to the existing vent pipe above floor level

I attached sketches earlier of my proposed layout, waiting on moderators to approve

 

[pipehandyman]

nvm there they are.

 

[pipehandyman]

the empty space at the bottom across for the washer is intended to be a closet

and the BLACK CIRCLE in the sketch is the cast iron stack leading up to my first and second floor bathrooms (half and full)

 

[frodo]

my thoughts

 

[pipehandyman]

to the right of the sink in the new bathroom. the circle is that a vent?

 

[pipehandyman]

hmm well you labeled everything correctly, but (unless you feel I should reroute the laundry sink.) the laundry sink is already in place and the washer waste just dumps into the sink. my biggest concern is the addition of the toilet sink and shower and being able to vent properly and now the clean out which I did not know about.

im guessing from your sketch I am! allowed/able to tap into that "Wye" looking joint?

I tried copying your drawing will it work? and will the toilet sink and shower be vented through the main stack then?

thanks

 

[pipehandyman]

woops. here is is

 

[pipehandyman]

and if you have a better configuration (in the above the toilet is last on the line that gets washed out by the sink and shower, can it be the first thing since it might make it closer to the sewage stack and ran differently?

I hope with your help I can get the easiest best solution I attached a blank page if you wanted to run me a better option.
I really appreciate your expertise.

I know photos help a lot, so I didnt have it before but this is the designated area for the bathroom.
I dug out alot of the soil and dirt which enabled me to find the "wye" looking joint.

I see, I was hoping I could avoid that orange vent pip you added underground but I guess that I cant do without it.

could you help me to understand the washer section you added? im only familiar with washer where they dump into a sink and then go into pipes/sewage. if the tube used to exhaust the water waste from the washer into the sink is not dumping into the sink. how would I go about attaching the washer to a pipe sticking out of the wall or floor. would it just be direct connection does that just mean I have "two sinks" essentially as far as the connections go (one as an actual sink thats present, and the second where a washer is attached instead)?

Hi Frodo

with your help I have been understanding a lot more, I made a new drawing and wanted to see if you think the layout is good or needs to be modified. I just switched location of sink...

one last question I had is if I would need to add the trap similar to the one at the cast iron stack or does the clean out served the same purpose that the trap does for the iron stack?
