    After many hours of reading code and reading old posts on this forum I've managed to design this small DWV system for a new cabin.

    Please review the following 5 images and let me know if anything appears to NOT be legal for Florida's IPC.

    The PN# referenced in the jpgs come from Charlotte Pipe's PVC DWV Dimensional Catalog
    Thanks in advance,
    Steph

    No, no and NO. And Florida is an IPC state. Most of your vents are flat.

    And good eye Tom Sawyer, you are correct I failed to slope the horizontal runs of the vent. I can fix that. Thank you.

    Anything else here that does not met IPC florida?

    It's not just a matter of pitch. The vents must be vertical until they are at least 42" above the floor. Your drain routing will need to be changed to accommodate the vents.

    You also will need to lose the vent tee on the utility sink. You cannot use vent components for drainage. Is also appears that the sink is on the floor, with the trap below the floor, so I am guessing that the drawing is wrong.

    I'm sure others will pipe in, as I am on my way out the door.

    The wye you have taking off for the stanpipe vent should be turned the other way..allows for "smoother" air flow drawn it from vents and also allows for proper draining if/when water gets into vents. But as others have said you have some flat vents also.

    Oooh is THAT what Tom Sawyer meant by "Most of your vents are flat." Not the he had eagle eyes and could tell that the horizontal vent pipes forming branch vents were not sloped but that leaving the Ptrap many of my vents do not go vertical nearly enough before going horizontal.

    Thank you SO much for clarifying what he meant by that.. NOW i understand is not just and slight issue of pitch but of the entire layout.

    A "flat vent' is a vent that does not meet the following-

    Thanks cacher_chick, now i understand. :eek:

    Ok, good eye that makes sense. I'll figure out the right series of fittings to use under a double sink. I used the same (wrong) configuration on both the kitchen and utility sink. - thanks again.


    Here is better perspective of the same layout. I hope it makes more sense.

    Thanks Hammerlane regarding the position of the wye on the vent of the lav sink. That is a great drawing you used to show turned the other way.. I get it! :)

    However, in that instance i am trying to get to the other side of the wall in that direction.. in the direction it is currently orientated. And am going up at a 45deg to avoid creating a flat vent there.. soooo even though it might not provide the smoothest airflow at this point I am merely trying to determine what is LEGAL.

    I think you are saying that although it might be legal under IPC to use wye in the manner i have it- better airflow is achieved turning the wye in the other direction.

    The flat vents I am showing on the shower and water closet are my only real concern at this point. But they are big ones.

    It is NOT legal because it goes against the flow of the drain line, and has nothing to do with "smooth air flow".

    oh really?
    I had no idea. I clearly did not understand his comment the first time then. Thanks for clarifying that for me - I thought he was saying it was legal but not ideal.
    You guys are awesome!

    Just so i understand what you are saying.

    " SECTION P2607 WORKMANSHIP

    P2607.1 General.
    Valves, pipes and fittings shall be installed in correct relationship to the direction of the flow..."

    And the CORRECT direction of flow for a wye fitting is ALWAYS in the direction shown here.

    It does not matter if the wye is used for a drain or a vent, if it is horizontal, vertical or sideways. When i see a wye i should think strictly in terms of

    EXIT ONLY.jpg

    Is that correct?

    I know I don't have any helpful information, but I'm wondering what program you used to get the layout of the pipes. I'm also curious about where and how the stand pipe hooks in. I'm trying to plan out a bathroom/laundry room as well and am trying to figure out the correct order in which to connect things. So far the info in this thread has been enlightening.
