Trap Arm Restrictions
Trap Arm Restrictions
(OP)
I'm looking for any code reference to limitations on change in direction of trap arm before connection to vent, as well as whether or not two or more traps may be joined to the same trap arm (separate, parallel connections, not in series). Thank you.





RE: Trap Arm Restrictions
IPC and UPC have chapters dedicated to vents and what is required and prohibited when it comes to venting fixture traps. I suggest careful reading through the code you use most. To better answer your question we will need more information about the setup you are looking at, there are too many variables/options to provide meaningful advise with the information given.
RE: Trap Arm Restrictions
Although a different approach, you could argue connecting the trapped fixtures as you describe would comply with some of the wet vent sections, like combination drain and vent. Refer to some of those requirements to see if your situation can fit into one of them.
