I’ve got the same exact problem in the basement I’m finishing.
I want to cut the slab and run a sink/dishwasher drain into a floor drain like his (because it’s far closer than the stubbed out ones).
My question is do I need to vent that drain connection to an existing vent stack or can I vent the the drain under the counter to a closer exterior wall and make a new vent just for this new drain line?

On the vent issue, there is a device, a one way vent that screws onto the top of a 1-1/2" pipe. I don't know the name of it but it's a simple plastic gizmo that lets air into the pipe but doesn't let the gasses out. Building codes vary so you may or may not be allowed to use one. But go to your local plumbing store amd ask for a "cheaters vent". They know what it is.
Does any one know what it's called?

I'm building a bar for a customer which will be placed in the basement. He wants to have a bar sink installed. The sink will be located along a partition wall which contains the house's furnace and hot water tank. There is a floor drain in the utility room. Is it acceptable to drain the sink directly into the floor drain? What about venting the drain? I'm not a plumber, so I haven't dismissed the idea of sub-ing the work out. Thanks for the advice.

*Hi Dave,No it wouldn't be my choice to go directly into a floor drain.There must be several lines in the basement that you can tap into instead. The idea about bringing in a plumber would be your best bet so that he can locate a better pipe for you to connect to. Just make sure that he checks his sawzall at the door, though.Gabe
*If there's a floor drain, there's a stack nearby.Tieing into a vented stack is the best option. If by draining into the floor drain, you mean busting out the floor and tieing into it, the only thing to worry about is venting the sink. I'm kinda assuming you didn't mean running some garden hose to it. Try to guess what direction the line from the floor drain runs. Pick what's closest. Jeff
*Dave,If you have an air gap between the outlet from the sink and the inlet to the floor drain you won't need a vent. This is generally accepable, but you must check local code to be sure.I mention the above as an alternative; I don't thinks it's the best way to do it. (See other posts.)Jerry
*or possibly loop vent. same diff. Jeff

*Doing it in the basement is no different than doing it anywhere else. The sink drains thru the trap and horizontally ties into the stack with a vent pipe tying into the stack 6 inches above the sink drain.
*When I lived in CT. we added a bath in a basement, to avoid messing up the concrete floor we raised the bathroom floor 12" to allow for plumbing. Would this help in your case

In our neck of the woods the brand name is Studor Vent. Must be accessible for inspection and/or replacement in case of failure.
