Plumbing Double Vanity sinks 36" apart on center


Hello Folks,

I live in Winnipeg Manitoba Canada and I want to know if this plumbing idea I have for my double vanity is legit or not

The sinks in the attached picture are connected to traps that connect to the cross pipe using a 45 Street elbow for the left/end trap and a WYE 45 for the right trap

Any help on this would be much appreciated, thanks!

anybody have any comments on this?

is it legit anywhere? will the right hand sink pull water out of the left hand sink's trap when it drains?

Per UPC each trap needs a vent. I don't know your code.
You can use a common vent by moving your stack between the 2 lavs and using a fixture cross. Or 1 trap to your existing stack by means of a continuous waste between the 2 lavs.

I don't think I can use "continuous waste" because the drains of the sinks are more than 30 inches away from one another....

how about if I extend the vent to go over one more stud and then down to be between the two traps?

That works. Now both traps share a common vent

another question I have about this is, what angle should the clean out be? 45 degree angle cleanout or a 90 degree angle cleanout?
