I am finishing my basement. I thought all my rough was done including plumbing and was about ready for sheetrock. My boss (my wife) was looking at the bar layout with her friends last night and wasn't happy with the layout. Would have been nice to have had that feedback before we spray foamed everything in. So I know have a "change order" to rearrange things including the plumbing.
The bar sink is the only drain on this 2" drain line other than the dishwasher which will be next to the sink. The drain line runs horizontally though the wall before tying into the main drain stack. The drain is vented up through the wall with a 2" vent. I have to move the sink and dishwasher either 4-5 feet to the left or to the right depending on how we do the cabinet layout.
Moving the sink to the left would simply mean extending the drain line another 4 feet. Not bad other than the spray foam. With slope this would place the rough drain center at about 18" off the concrete but since there won't be a disposal I think this should be OK with a small undermount bar sink
However, if I move the sink to the right it would place the sink drain and attached dishwasher downstream from the dry vent forming a wet vent). Is this OK since there is no fixture other than the vent upstream of the drain? All I have read around wet vents focuses on multiple drains using the wet vent, not a single.
Thanks for any advice.
Kind regards,
Dennis
