Location: Windsor, WI (Dane county)
I am working on finishing our basement off. I had a bathroom roughed in when the house was built so I have a shower drain, toilet drain and a DWV stack that is 2" coming out of the floor and after about 24" it reduces to 1.5" and then goes up and out of the house.
My question is regarding adding a bar sink and how to drain and vent it properly and to code. The bar sink would be at the standard height of base cabinets (36"). The bar sink is located about 7 feet away from the DWV stack (6 feet to a corner and then about 1 foot around the corner)
The bathroom sink would be at the standard 33.5" approx for a vanity.
My original plan was to run the bathroom sink directly to the DWV stack from the P trap under the vanity sink. The bar sink would have a P trap, enter the wall where I would have a vertical pipe go up about 4' then go horizontal around the corner and connect to the 1.5" vent pipe from the DWV stack. The drain line from the bar sink would then go around the corner and with the appropriate drop would connect to the 2" drain section of the DWV stack under the drain connection from the bathroom sink.
I don't think I have a drain flow issue as neither of these are going to be a constant use item. I believe the issue I have is that the bar sink is higher than the bathroom sink and therefore if it floods, it would back up into the bathroom sink.
I have uploaded a couple of pictures showing how I planned. The components are just pressed together right now.
Any suggestions on how to complete the project?
