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

You will need to vent the line from toilet to stack regardless of which one you use.

Sorry, I wasn't clear on the main stack; it is the main vent.

That being, which would provide the optimum water flow, A or B ?

Thanks,

What else ties into that main stack, and where?

Both will perform the same.

Well, this is assuming that nothing else ties into the main stack, and the main stack
is also the main vent.

I've posted this on several other forums and so far, the B's have outnumbered the A's.

The A proponents mostly say that it's a straighter shot, thus less chance of clogs.

The B proponents say that the A allows too much rush of water, thus restricting the vent.

I'm still 'up in the air' about which one to go with, but, not being a plumber,
if left to my own impression, I would probably have chosen A.

Anyone have a strong argument for either ?

Thanks,
Arky

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

Thanks,

A. Otherwise you would need to vent the toilet in B. Also other drainage will most likely have a vent I assume.

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 ?



Thanks,
Arky

You will need to vent the toilet then...

Not sure what you are trying to do here but its getting silly IMO. Why not just buy a code book?


You have given 10 or so different senerios. ( This and your other post) I think you know what you need to do and if your not sure I suggest hiring a licenced plumber.
