Wow, I would have thought that a p-trap filled with water would have blocked gases from the drain waste vent system. What's going on here, do the vents not vent all the way to the top of the building but come out the sides of the buildings? Guess they'd have to at some point as the number of stories goes on and on.
- downerending 6y agoLived briefly in a NYC flat. One of the p-traps did not in fact function as intended. The details are unpleasant, so I'll leave them out.
- ToFundorNot 6y agoMost likely an S trap then. They are no allowed due to the probability of self siphoning. Not to say an S wouldn't, but it's improbable.
- downerending 6y agoIt was a p-trap with a non-obvious hole the size of a nickel. Became obvious the first time I used a plunger. :-P
