Hey folks, I have a couple of questions on how to rough-in a kitchen island. As you can see in the photo above, I have already roughed in a wall sink. We want to now relocate this sink to the island (thus the trench).
I would like to leave the stack and cleanout at the present location (just get rid of the drain stub out). I will also add an AAV at the sink location, if I have to. The distance between vent and proposed sink is about 8'. Since the top of existing drain is about 9-1/2" from the top of the concrete slab, don't think I have the depth for a loop vent setup.
The 2" drain line angle looks as if it will need 135 ? degrees of turns. So is it best to install a combo tee, or a wye tee, plus (what degree) other els to get to the direction of the island, code wise.
As far the water supply, if using type L soft copper, what is the industry standard as far as sleeving? Or should I go with something other than copper? The lines on the wall side will be brought up in front of the finish wall, hidden inside a pantry cabinet, with cut-off valves.
Thanks for any help
