Toilet Drain
 
Which of these is the best configuration for a toilet drain ?

Going to assume that C is incorrect because of no immediate vent pipe; that leaves A or B.
Which one would be the best configuration ?

Thanks,
Arky

If the "MAIN STACK" is a vent and not a waste stack to an upper floor then I'd guess B
Whats the prize?:laughing:

Thanks Eplumber,

(No prize :) ) I was going to go with B at first, but then I thought that A would be more
of a straight shot, however, I still wasn't sure.

What makes B a better choice than A ?

This image shows water flow in a sinks trap arm, same applies for toilets. A wye's configuration at it's crotch restricts air movement to the trap.

Makes sense, thanks.

In the following picture, assuming that the 'other drainage' pipe cannot be moved, which would be the better arrangement, A or B ?

Thanks,

A is the best. this is assuming that the has nothing connected to it other than a lav or nothing at all.

Are you taking a test or something? I'd hate to give you quiz answers :jester:

No test :) ; I'm just an old (67) geezer, hoping to get my plumbing right on my retirement house
so when I get to old to move around :wheelchair:, hopefully I won't have any plumbing problems to deal with.

One last time on the toilet drain.
Because of obstructions and space limitations, I need to have the toilet drain into the
stack lower than the tub and sink.
Would there be any potential problems with this arrangement, that is having the sink and tub drain into the stack about a foot above the toilet inlet ?
