Help With 3 Basin Kitchen Sink Plumb


I am a General Contractor starting a full renovation of a kitchen. The home owner has chosen a 3 basin kitchen sink. The disposal will be placed in the center basin.
I am very familiar with the 2 basin plumb in, however I am unable to find legitimate info elsewhere about how to properly tie all the lines together. I also could not find any good schematics or pictures either.
Any detailed information will greatly be appreciated!

But true. Why not just ask your plumber? It's what I do and he asks me about framing or siding, or the things I do. It's how it works.

3 p-traps--and a 3 outlet Y--

Best would be to redo the piping inside the wall to give you 3 trap openings.

All normal double sinks I have seen only have one P-trap, why would this one need 3? I could see 2 for ease of install.

Not a plumber so just asking.

Fwiw...

I just replaced a double bowl sink where separate traps were needed so I wye'd it in the cabinet. Otherwise, the combo drain would have required a lower P-trap (and arm) to make it work.

Re: Help With 3 Basin Kitchen Sink Plumb


Doesnt sound right, but I wonder if this triggers the need for a 2" trap.

In our area every sink needs its own P-trap---
