need some advice on plumbing drain / vent

[jakester]

Is there a limit or a rule to how many turns a vent pipe can have? I am going to try connect this vent to the main vent stack but that might require a decent amount of 90 degrees angles / turns.

no, air dont care. LOL..i would advise a clean out at the base of the stack.

rule with a vent, it can only rise, you can not offset down

i installed a vent one time that followed the stairs up.

do you mean clean out at the base of clean out stack or vent? Also what is the purpose of the clean if it will all be covered by drywall?

 

[frodo]

jake...are you messing with me? why the hell would you cover a CO with sheet rock?



because, if you ever want to rod the sewer out..you will never get a snake around a bunch of offsets

I am sorry! I am not messing with you and I didn't mean to come across that way.. This was and will be a finished laundry room and will get drywalled and I wasn't sure where I would put the clean out and why i needed it there.

to make it a little clearer - when I said this is in the basement i should have been more clear, this is a bi-level house and the laundry room is on the lower level which is about 3 - 4 feet in the ground, not an actually basement.

shouldn't I only need one clean out drain in whole plumbing system? I know that there should be a clean out at the main drain.

Thank you everyone for the great advise / info!!! I really do appreciate it!

yes you need to get that trap out of there and just trap the stand pipe for the laundry by itself and add air admittance vale

Are you saying i should separate the sink drain and the washer drain? I think the diagram that frodo posted will work just fine.
