I am installing a new toilet in my basement and am doing the rough in. I have some problems with space, can I use a 3x3x3 tee y on its back rather than a y?

My gut tells me no but I am hoping that I can.

More info is needed, and no if you are asking to tie the toilet riser and flange off of the tee with tee on it's back, then no you can't do that, pictures would be of great help.

The only place I know of where you can lay a tee on its back is in Kentucky. That may have even changed. If theres a KY plumber out there, I'd be curious to know if this is still the case.

What is your definition of a T/Y? If you mean a combination Y-1/8 bend then it is a proper fitting in a horizontal line in any orientation, but if you are that tight, then you may not have room to install a proper vent for it.

Thanks for the input guys.........I managed to rework the lay out and got it done with a Y. It was one of those deals where it was infinitely harder but..... easy is not always the best way.

Plumber 2000, the other end of the y is going to another to new toilet. I put a y into the main drain then y'ed it again with each going to a toilet which are back to back. (bedroom bath and a 1/2 bath).

You are getting vents in there somewhere aren't you, and in the correct places, not just the easiest places to put them.

King,

Can you post a diagram showing the pipe layout, want to see if you have the vents for the toilets done correctly.

Last thing you want under the slab is it done wrong, and you start having problem when your ready to use them.

Hey guys, I have no way of posting diagrams but I have each line vented seperately between the toilet flange and the respective Y. They are 1 1/2 inch vents that are then joined together at a Y and then the vent goes vertically up into where my wall is going to be. From there I am going to circuit vent to my existing vent which of course exits the roof.
The vents come off the drain line with a 3x3x1 1/2 tee. I tried my best to use a 2 inch vent underground but did not have the room.
I have a buddy who used to be a plumber and he said it should be fine.
Comments?

Back again. I was just looking at your diagram Plumber 2000 and it is set up like your right hand diagram and then the two are joined together to exit the underground.

Here code says min 2" vent for toilets, if you had that inspected good chance inspector would have turned it down.
