Owner builder in Sequim WA looking for feedback DWV

[Chuck_SequimWA]

My wife and I are building our own house in Sequim WA and are hoping to get some feedback on our DWV layout.


Where should the clean outs be? Currently we’ve only planned for:
-One in back to back bathrooms under sink

-Just outside house on 3” pipe on way to septic

-Under floor near crawl space access


The foundation is a stem wall.

Can I drill a 2” hole in a 2x6 king stud under a window?


I’ve broken the layout into several pictures in hopes that it will be easier to review. I’ve also attached EntireLayout.pdf which is the entire layout, but is very busy looking.


We’d appreciate any comments on our plan. We hope to live in this house a long time, so I want it to meet code and function properly.

Thank you all

It would be a LOT more legible if you removed the annotations, many of them are incorrect anyway.

I have always seen 4" stubbed to the home from the septic.

The double wye is good for the back to back toilets.
The washer needs a vent and the laundry sink needs a vent.
It's a double fixture fitting for the showers and the lavs.

Thank you for taking the time to look at our layout. I’ve uploaded a new file EntireLayout_NoAnotations.pdf without annotations in hopes it will be more legible.

Thank you for taking the time to look at our layout. I meant for the washer and laundry sink to share the 1-1/2” vent. I’m wondering if all the annotations hid it from view. I’ve uploaded another file EntireLayout_NoAnotations.pdf that hopefully makes it more legible.
