    Default Definition of "Trap Height"

    P2706.2 Standpipes for automatic clothes washers shall extend a minimum of 30 inches (762 mm) and a maximum of 48 inches (1219 mm) above the finished floor. The trap for a clothes washer shall be installed at a maximum of 12 inches (305 mm) above the finished floor. Access shall be provided to all standpipe traps and drains for rodding.

    Trap height is measured at the trap weir, correct?

    JP: Please note that, in my first post, I directed Michael to the proper citation - to wit, the one you now quote.

    Also note that, in my second post, I acted entirely out of memesis after experiencing your sapient illustrations over thousands of posts by artfully stating that "it appears to be", and not "it is so". My intent was to inveigle you into your current response. Or, I was just wrong. You decide . . .

    Yes.

    The rest of the trap would be the 'trap depth', which is not the same as the 'trap seal' depth. The 'trap seal' is the critical depth and is required to be 2" minimum and 4" maximum.

    Jerry,

    I've gone back into my notes, and truth is, I don't know where that cite is form, it pre-dates the time when I started to note the source on each entry and the only place I can find something similar via GOGGLE is www.kcmo.org/codes/CH18/2003/CH18ART3.pdf - my guess is that it's from my early days, and I assumed that the requirement of some local municipality I encoutered was unadulterated IRC.

    Michael, Kentucky requires washer p-trap to be 12" from trap weir to floor. So it may be in the local plumbing code???

    Aaron,

    That's not, that's being truthful.

    You use big words like that and I have to look them up.

    Which means you got to keep them simple ...

    Well, okay, not simple like in 'See Dick. See Jane. See Spot. See Spot run. See Dick and Jane run after Spot.' ...

    ... But like "Also note that, in my second post, I acted entirely out of memesis after experiencing your sapient illustrations over thousands of posts by artfully stating that "it appears to be", and not "it is so". My intent was to inveigle you into your current response."

    Huh??

    JP: I'm always (almost) being truthful.

    JP: Turn about for my having to research your often obscure code references, or having to follow your over-the-top and unabashededly intricate lines of "reasoning".


    Which means you got to keep them simple ...
    JP: You too. But then, if simple means inaccurate, maybe not.

    I was not referring to you as not being truthful, I was referring to me, that I was not whatever-you-said, I was being truthful.

    After reading your reply I went back and re-read what I posted, I can see where my meaning was not clear.

    Sorry about that.

    Why, did you have to look up what "Whoooosh!" meant?

    Hi Mr. Thomas,
    Illinois plumbing code (Title 77: Public Health, 890 Illinois Plumbing Code), page A22, does not show a term "trap height" but it does refer to the trap seal, as shown in your diagram.
    The dfinition refers to an illustration in Section 890.Appendix B, Illustration W.
