    Default Laundry waste line trap size

    This laundry drain trap is "slightly" over sized.
    I was curious what may happen as a result of this, does anyone have any info on drain traps?

    That's just a big mess, and the size is the least of the issues.

    Dis regarding all the other issues, an oversized drain trap will not scour, so it can plug up easier.

    Looks like 2" to me, if 2" not a problem.
    But the trap depth.... well.

    I think the photographed "squeegie" leaning against the wall and the soil stains on the waste stack and the floor say more than 1,000 words.

    One word: EwwwwwwYUCKiePooey! (okay not really a word).

    Dangerous: Heath Hazard, Public; Contamination. Licensed Plumber, Master Level, Unpermitted, illegal modifications, Unsafe. Back flow, unvented, cross contamination to water supply.

    Need some understanding of waste plumbing? New York State Plumbing Code, its a read.

    Looks like a standpipe which someone decided to extend, possibly because they were getting odors and sewage out of it ...

    ... which would make sense because the fitting which was used to connect into the main stack instead acted to connect the main stack into the stand pipe (it looks like a wye installed upside down, meaning some of the crap from above is going to exit into that standpipe.

    You know the old saying, right "**** flows downhill"? Well, that photo is a good depiction of just that, and "downhill" is into that standpipe, and liquid seeks its own level, so the standpipe would be full of it too - to the level of that fitting opening into the main stack.

    If you have ever worked on a clothes washer and seen it shoot a one inch column of water across the garage, you wouldn't worry about sediment buildup in the trap. Actually I'm not sure that a standard height trap would leave water in the trap due to the inertia of the water.

    The beatings will continue until morale has improved. mgt.

    Impossible to tell from that pic if it's an upside down tee-wye or not. Could even be a straight tee. But regardless there is no good reason for the trap to be that long.

    It looks like to me it is that long so it can sit on the floor.
