What is your read on the UPC rules for emergency floor drains. (not IPC)
They have a 0 fixture count so I guess need no vent.
Do they even need a trap? What is min size?
They are not listed under residential so I assume commercial or assembly
This is my thought:
If you intend to hose the walls down sometimes then you need a regular floor
If you put a normal floor drain you need to have a vent and possibly a trap
If the floor drain is just incase water or other harmless liquids are
spilled or there is a leak and you don't want to flood out downstairs then
you need only put an emergency floor drain.
I run my drain down to basement where I have a standpipe to receive indirect
waste with an easily accessible trap primer.
Like the washing machine pan under the washer and its drain. Is that an
emergency floor drain?
