Reqd distance of sink to riser
Hi I am in the market looking at Co-ops and am always wondering what latitude one has in reconfiguring a kitchen.
If the waste, water, and gas risers are going to remain in place where they are, how much does NYC code allow/limit you to horizontally pipe away from these risers to a new fixture location?
Thanks to anyone who knows!

I believe, but can stand corrected, that it's the distance from the sink to the trap that's important, so you can place the trap near the sink and continue to the original pipe. But there may be an issue with vent piping as well.
Water and Gas piping should not be an issue if protected.

It depends what size pipe tou are running. Here's the critical distances for the national code. And, its not the distance to the waste stack that's critical its the disatnce to the vent. They should be one in the same.
Pipe diameter Distance to vent/waste
1 1/4" 2 1/2'
1 1/2" 3 1/2'
2" 5'
3" 6'
4" 10'
and it needs to slope 1/4" per foot.
Could someone else confirm these for NYC.

Yeah, but should it not be possible to extend the vent pipe as well?

Dave,
Thats interesting. So if I want to extend up to 10' off of the vent I could upsize my pipe to a 4" dia. even if code otherwise doesnt require a pipe that wide....
Good point by CMU about just extending the vent as well....

Yes, sloper. 4" will get you 10'
What do you mean by "extend the vent pipe?"
The setup you are referring to is called a "wet vent" I don't know if the code changes if you install a separate "dry vent" which would be a pipe off of your drain that rises UP and connects into the vent at a point higher than the drain.

Thanks Dave,
What I and CMU meant is that if you ran a horizontal vent pipe from the vent riser to the sink then the sink-to-vent distance would be minimal. is this not possible?
Also another seperate question, if you know?
I keep reading that kitchen's dont necessarily need a exhaust vent if the back of the kitchen is within 30 feet of an operable window. I cant seem to find this in NYC code though...
are you able to confirm?
Thanks again!!!

hire a plumber or tell me how i can have such a vast amount of time to even consider this issue

hire a plumber or talk to a plumber or tell me how i can have such a vast amount of time to even consider this issue. I think there are probably structural and monetary constraints that will actually be more significant than the mechanics of the plumbing code, but then again what do i know i only do this shit for a living.

Guess plumbers don't have to have tact. Oh, but you're not even one, so what's with this snarky response?
Posted by: cmu at January 24, 2009 12:30 PM
wow.
sorry jp2. didnt know a post on brownstoner would ruin your day so.
or even cause tourettes syndrome.
In any case, your post makes no sense. The difference between moving a sink 2' or 6' is probably going to be driven 1st by my desire to layout a kitchen better, and 2nd by whether code allows this length of piping, but less likely by monetary issues or structural (WTF?) issues. Perhaps you think four linear feet of pipe costs a fortune and is such incredible load on the structure that I should consider underpinning the foundations, but I can assure it is neither. If you were a plumber you would know this, so as CMU guessed, Im thinking you're not. Now put down the beer and go try to find a job young man...
