I’ve seen P traps and S traps, but this W trap is a new one. The corrugated plastic pipe is a nice touch too. 
I see they have first-aid supplies handy in case a vein bursts!!! :mrgreen:
Double trapping is not allowed.
I know Bob - I posted the picture for amusement.
Bill, you forget Bob has no sense of humor (which means he won’t see the humor of my post) :mrgreen::mrgreen:
Commonly known as an “N” trap. Not allowed at all, not in the American Legal System, Ask Joe Ferry: N Trapment is not allowed.
:roll::roll::roll:
But funny!
Looks like triple trapping to me.
Sorry but I do not know you well enough to know if you are goofy.
What? Did you say something?
Don’t say I didn’t warn you Bill. 
Nope! :twisted:
If you purchase enough of the wrong parts, you don’t need any of the right parts…
foshizzle…
That’s my motto… 
Check this trap(s) out. This was a fun find.
How in hell did that thing even function is my question. ;)
It always amazes me when I see this kind of crap work, and realize that someone actually put some thought in on how to do it. :shock:
