DWV layout review


Hi, I'm looking for a little feedback on updating my dwv. I've attached 2 images, one is the floor plan, basically two stacked bathrooms and kitchen right next to the first floor bath room. Currently there are no vents for the shower, tub and laundry, there is no laundry sink, and the vent for the kitchen sink is about 6" below the the flood line instead of above. Also, there is a mix of cast iron, pvc and copper. I'm hoping to fix all of that. I'd like to start with just the layout out so assuming the correct pipe size, slope and connections how does this look?

On the iso.. eliminate the dotted line layer. It's just confusing.

I'd be real surprised if that's all true.

If the iso drawing is showing your *proposed* work...
then please do another for the existing layout.
And a 3rd drawing for the proposed changes (using a different color).

Aside from the kitchen vent question... what's "broken" about it?

Here's the drawing without the dotted lines:

I've have to work on the drawings to get the old and the proposed done.

The drain for the first floor shower attaches to the horizontal run to the lav and the kitchen sink so maybe it's wet venting from that. The tub/shower ties into the toilet run and there is no vent unless it's vent from the main stack. The laundry arm is just a wye into the base of the stack. As for the kitchen vent, I can see the vent for it running through the corner base cabinet.

As for what's broken, besides the lack of venting, the is a slope issue with the kitchen drain, I already had to get a section of the cast iron replaced between the first and second floor because it was cracked. The piece of cast iron going through the roof is currently crack.

I'm planning on doing a kitchen and first floor bath remodel and I figure it the perfect time to fix everything.

I'll get that old/new drawing up soon.

Thanks,
Tee

Do you have a window, directly above the kitchen sink?

There is. I was planning on going around it to get to the proper height.

Thanks for the first one... the second will help a lot.
Of note: Where I'm from those other two stacks would need to have vents extended to the attic level at least (to join with main vent) or be vented on their own.

Not saying your wrong (I'm not there)... just that it's unusual. Real unusual

I'm the same way... (if/when I have a wall open etc).
Your scope seemed rather ambitious absent other reasons to be opening a lot of walls.

DWV layout review


Here's what I have for the existing.

DWV layout review-untitled3.jpg

The floor plan is slightly different from the one I upload. The bathroom sink in the first floor bath is actually on the outside wall, same a the kitchen sink and there is another chase in the corner between the bathroom sink and the wall to the kitchen. That is where kitchen vent is going up. The dotted line is a possible vent for the first floor bath. I haven't opened that chase yet so I'm not sure if it's there or not. Wouldn't surprise me if it wasn't.

Those vents in my proposed drawing are attaching to the main stack int he attic.

DWV layout review


So I've added the fittings. I assume everything needs the 1/4" per 4' slope, down for drains and up for vents?

Should I use wyes and 45s for the combo y 1/8?
The elbow at the bottom of the two sinks stack, what should I use there?
thanks,
