Toilet Waste Line Running Sideways ...


my wife has convinced me to convert the 4th bedroom in our house into an ensuite ... only problem is that now places a bathroom in the back corner of the second story of our house - where the sewage lines are in the middle of the front and back of the house.

so my question is, how far can / should I run a toilet waste line sideways - to get the sewage line from the corner of our house to the middle of the house?

can / should this even be done? - I assume I should have a 'slope' to the line - but what's an effective rise/run for a toilet waste line?

hopefully this makes sense ... otherwise, here's an attempt at a picture...

where X is the toilet location on the second floor
and O is the sewage drain location in the basement
(nevermind the "-" needed to have something there for the spaces).

any info would be greatly appreciated!

For a toilet you can run a 3" line the fall the the line is 1/4" per ft also you need to install a vant for this drain

Not necessarily. The applicable code where I live is IRC 2003, which does not require toilets to be vented. I just had my plumbing put in by a licensed plumber, and he did not vent the toilets.

All fixtures require venting.

And how far away from the stack is your toilet?

I would also bet that your toilet is vented and if is not then even under IPC 2003 it is not meeting code. The IRC (International Residental Code 2003) and the IPC (International Plumbing Code 2003) states it must be vented by either distance from rhe stack or if over legal distance then by an individual vent.

By the sound of this mans install it is going to be far away from the stack and will need vented

YES YOU ARE SO CORRECT WHERE YOU LIVE THEY DON'T NEED VENTS BUT
THAT IS BECAUSE OF 30 PLUS YEARS IN PLUMBING
I HAVE NEVER EVER SEEN A "OUTHOUSE" THAT NEEDED VENTING !

Section P3105.1 of the International Residential Code 2003 states:

"The developed length of the fixture drain from the trap weir to the vent fitting for self-siphoning fixtures, such as water closets, shall not be limited..."

I guess my statement was technially incorrect. What I meant to say is toilets do not require a separate vent. The stack itself is the vent.

While you are trying to justify your answer you are still wrong.

What that is refering to is the developed length of the drain from the trap weir. Because a drain line from a trap weir depending on what size pipe is used is limited to a specific length.

So if a toilet drain is connected to a stack at any lenght will require a vent, wether a common, individual vent or wet vent by a bath group

We won't talk about when six toilets are on the same drain and require a relief vent.

What you posted just stated that the developed drain has no limit to length because it's a toilet
