Laundry drain, vent, and floor drain

[PrecisionPlum]

Does this layout work?
I'm still having trouble understanding venting.

The floor drain has no trap, but I designed it
using a Sure Seal because:

1) Requires no trap, thus no trap primer to worry about
2) Easy to remove so the drain can act as a clean out

Your thoughts?

what are the drains for?

Frodo, thank you for your response.

Can't this be treated as a Waste Stack Vent system (Section 910)
if the vent is changed to be the same size as the wet vent, ie. 2 1/2"

Frodo,

Learning by discussion is very helpful. What is it that you
don't like about treating it as a Wast Stack Vent system?

I am a plumber that has installed plumbing using the uniform plumbing code [UPC}
in that code it is not allowed
the new international code [IPC} allows all kinds of things that are illegal in the upc
quite frankly in my opinion the IPC was influenced by building contractors who simply want to build a cheaper house
and are willing to cut corners to do it

But hey man, I am also against the use of Auto vents, And believe that a house with more than 2 bathrooms has to have a 4''
trunk

The possibility of the lower drains vent being cut off by the upper waste is what chaps my rear end.
