Hey, I just stumbled across this forum and I think I have reached nirvana!
I am finishing my basement and have reached the point of finishing my bathroom. It was "stubbed" by the builder, but I just don't know what each pipe is for. I have posted a pic here: http://i6.photobucket.com/albums/y20...a/bathroom.jpg
There is a 4" pipe in the floor, a 2" pipe in the middle in front of window, and a 2" pipe located close to the 3" pipe, but very near wall.
I obviously know what the 4" pipe is for, but am confussed on the 2" pipes. Could the one by\in the wall be a vent, or perhaps one is for a shower\tub and the other by\in the wall is for a sink?
My boyfriend has been a plumber for 20 yrs and he believes that the 3'' in the pic must be for the toilet with the 2'' behind it being the toilet's vent. The 2'' under the window would be for a vanity. As far as he can tell from your description, there is only plumbing for a half bathroom. But he needs to see more pics to be sure.

Any guesses or help would greatly be appreciated!
The 4" is a toilet stubup. The 2" upright pipe behind it is the pipe you will come off of 18" from the floor to the center of a 2" DWV drainage tee turned to the right with a laterial, (horizontal) 2" pipe extending up to 5' inside the wall to elbo out and pick up a lavatory or vanity. The top of the drainage tee continues on out through roof, or revents into another vent in the attic, as the vent for the entire bathroom group.
The stubup out of the floor is a rough for one of two things. If it's about 15 1/2" off the nearest wall and 60" from the far wall then its a bathtub rough in.
This rough could also be framed out for a walk in tile shower.
What you have here, my friend, is a basement rough in for a full bath.
Good luck, Tom
My next question would be concerning the vent pipe in the wall you mentioned.
I asked a plumber about ways to not have to run the vent all the way up through the roof. He said I had two options. First, he said I could put some kind of mechanical vent under the sink like I have in my kitchen, or second, I could vent it out through the exterior wall.
Venting through the exterior wall would require brick work as it's the front of the house , so I would REALLY like to know if option one is A) feesable and B) what kind of vent I should be looking for at HD.

Thanks again for any help!
No problem,
Your plumber was bang on. The spring loaded mechanical vent that you refer to is a Studor Mechanical Vent that's manufactured a little north of where I live. This vent will be placed on top of the drainage tee and will be all you need to vent your bathroom group.. Check them out at, http://www.studor.com/homeowners.htm
Glad I could help. Tom
Thanks again for the reply. Can I just leave the vent on the top of the T in the wall (behind dry wall), or does it need to be somewhere else?
thx,
Dan
On top of the tee is fine, or if you wish you may elbo off the vertical pipe and install the Studor on the lavatory stubout under the cabinet. That way if you ever had to replace it will be handy to do so. Regards. Tom
We want to install a clawfoot tub centered infront of the window. However, the floor stub for the tub isn't located in any place that would allow this placement.
My idea was to make a raised floor section to place the tub upon to allow pipes to run under the tub unobstructed. (6" raised)
Do you see any problem placing a 90 on the top of the tub stub and a horizontal section to "move" the tub stub? (Would use a second 90 at the end of the vertical to connect to the tub drain(s) pipe.) Of course, the horizontal section would need to have a slight downhill angle.
Again, thanks for you input...it really is helping a ton, and will save me quite a bit of money.

Hi Dan, Glad we could help.
You're proposing a "dog-leg" and that's the kiss of death to drainage. Especially lavatorys and tubs that send a lot of hair down the drain. If I had my druyhers I'd bust the concrete, ( Your builder should have left a tub dap out if he knew you planned on using the rough) and move the trap. How ever you asked for a reply. Since it's a clawfoot you can get under it. In place of the top sweep (You are using long radius elbos, aren't you?) I would install a drainage tee and put a 2" clean out in the end . You'll thank me for it later. Cheers, Tom

So, while "dog-legs" aren't illegal, they are frowned upon...correct? Therefore, if I use a clean out and large radius bends things will be legal....however, I should be ready to use the clean-out due to the increase in the chances of clogging.
Just curious how a dog-leg here is bad, but is "ok" up to 5' for the sink? I would have thought that to be a bad idea as well given the hair clog issues. Should I use large radius bends for the sink as well just to be safe?
