New code 910.4 2024 can anyone explain this one to me ??so u can add 45 on horizontal trap arms now ????
There's nothing in the specified section about offsets or angles. As tuttles said it's referring to combination waste and vent system.I think he's talking about offsetting the drain/vent itself. It's always been legal to offset it. It is specifying (and always has to my knowledge) that any vertical offsets need to be done with 45's so that the upper part of the piping maintains air space. The trap arm's need to stay horizontal with the main trucks, but the main trunck can be offset using 45's only. No 90's as they can cut off the airspace inside of the top of the piping.
I didn't read the code section he referred to.
Yes combination waste and vent systems are what I'm talking about.There's nothing in the specified section about offsets or angles. As tuttles said it's referring to combination waste and vent system.
yes they do allow offsettin trap arms upc 910.5 but no one is asking about that code?Yes combination waste and vent systems are what I'm talking about.
The ipc does allow trap arm's to offset vertically with no vent on the upper portion. Basically ipc allows S-Traps for combination waste and vent systems and upc doesn't allow that. Upc just specifies that the trunk can offset up with 45's only.
They no not allow trap arm's to offset up. Branches may offset, but branches with traps can only slope at 2%.yes they do allow offsettin trap arms upc 910.5 but no one is asking about that code?
