Tee height for kitchen sink

[magicalpig]

I have an drain stack that I want to tee into for my kitchen sink drain. It's about 18" horizontally away from where the sink will be.

My first issue is how to run the drain 18" horizontally. If I rotate the Tee such that it is in plane with the wall, the pipe will need to bore through loadbearing studs. If the Tee points into the room a little bit, the drain will need to cut diagonally through one of the cabinets before finding its way into the sink base cabinet.

Second problem is height for this Tee. How can I find its proper vertical position it if I don't yet have the sink? if I don't yet have any specs about the food disposal I may or may not include? if I havent even determined countertop height? Am I wrong in assuming there is one and only one correct placement for the tee so that the drain from the sink connects with it, or will there be some adjustable factor such as a telescoping trap or something involved?

Any help would be greatly appreciated!
Thanks

This website illustrates a similar problem. They create a drain stub-out for the sink at a height determined by running 1/4" per foot from the waste stack. But they don't talk about how to make the sink connect at that height.. do you just add pipe after the trap to keep climbing as high as necessary before meeting with this stub out?


isn't 1 3/8" max diameter for a hole in a load bearing stud? here they're running 1 1/2" pipe through it? Is some kind of reinforcement used?

The only "wrong" height for the tee is when it is too high to make the connection. There is no height that is "too low" unless it is down at the bottom of the cabinet.

Anywhere from 15" to 19" is a safe bet, unless you plan on 10" deep sinks or more.

Any comments about running through the studs?

IT is done all the time. Either you have to drill the studs for the waste arm, orif the drain is at the sink location, you have to drill to run the vent around the window.

simpson makes an item called a stud shoe for 2 x 4 or 2 x 6. it wraps around the side of a stud over a cutout.

The next "stud shoe" I buy to wrap around a drain or vent pipe in a stud will be my first one. I have never used any, and no inspector has ever asked for one.

i've seen large holes driiled in lumber that passed plumbing inspections but failed framing inspections. i would not bother a plumber to install a teco.

I'm not in any position to know, but I'm really surprised to learn how common & accepted it is to bore such large holes in exterior wall studs. Pipe for a kitchen sink drain should be 1 1/2" which equates to a 2" outer diameter? is that right?

if you make the hole have diameter 2 1/8" that's just about 60% of the 2x4's depth. I've read that 60% is acceptable if you double-up the stud; only 40% if you don't.

Is all this discussion about holes in studs useless? Do people even do holes or is it more often notches?
