Arrows are cleanouts. I have clear access to the top of the vent (flat roof)
would it be possible to put a cleanout near the question mark? I have about 18" clearance above that area.

Maybe rain water will clean it a little bit?
Interesting thought. But if everything is done right, what am I cleaning out of that vent? There will be a screen at the top so hopefully no smutz will get in there. Do vents need to be cleaned out?

I don’t think vents should be covered, especially in Minnesota.
Snow, rain, water vapor, all of these can freeze up and block the vent.

This is a capped screen. Like the kind used on chimneys.

Nah. Mushroom cap is one solution.

Sorry, I was picturing a crude mesh type screen like hardware cloth, which I have encountered a few times.
They freeze over very easily.

If the drain backs up into it. I’ve seen sewers back up into the sink drain under the floor and clog it with toilet paper.

Chances are that vents not going to do Jack. When you get done cap it off and see if any thing changes. I like running little tests like that, free education.

I would’ve ran it through those studs from the original stack. That would’ve been no problem. All that work was unnecessary.

I would’ve came out of the wall at the end of the red line with a 45. If that didnt clear the dishwasher I’d just drill the stud.

Then I’d add some studs and use plywood on the wall behind the cabinets instead of drywall to add support. I’m sorry ......

You said the dishwasher is going to sit to the left of the sink. Why do you have that electrical outlet there ? If it’s for the dishwasher it’s too high. I’d rather see it located under the sink if that’s what that outlet is for.

This house is balloon framed. Would rather not cut 2 1/4" out of a 2x4 stud on an exterior wall. The vent actually goes up into the ceiling and jogs left to go out to the roof.

Good tip on the outlet. I had it in my head that it needed to be directly behind the appliance.

As for your test, it probably won't make a difference. It's a fairly large column of air and would take a significant amount of force to create a vacuum. Like you'd have to run a firehose down the drain.

That said, our previous setup was a pain in the ass. Didn't drain for **** unless we ran the garbage disposal. So I have PTSD about poor drainage. I'm ok with overkill. PVC is cheap.

That’s why I would’ve beefed up the wall with more 2x4’s then used plywood behind the cabinets instead of drywall.

This would make it stronger than what you have now.

It’s done know, no problem.

See? Overthinking is a real problem. 😁

soon it will all be covered up and I’ll forget all about it.
Thanks for all the input
