New guy here...lookign for some advice:
I know it shouldn't be like this but it is and now I have to deal with it. The guy who's been working with me during the kitchen renovations (skilled but not a licensed plumber) wasn't paying attention and positioned the hot supply rough-in directly above the drain stack in the floor. I was traveling at the time and didn't notice this until after we installed the sink base. The 3" PVC drain protruding through the bottom of the sink base is in the slab is original to the house. The home was originally plumbed with copper in the slab but was replumbed with CPVC through the attic prior to my ownership due to a slab leak. We removed a wall during the renovation so the CPVC stub-out is new. The sink base is against a knee wall that is open to the living room.
I am going to be installing a Franke ORX-110 single bowl sink which positions the drain toward the rear and left side of the sink. I will be installing a disposal too.
I'm very concerned that the disposal is going to interfere with the drain which is going to interfere with the hot supply. The counter top has not yet been installed. It would very difficult to remove the sink base at this point without hacking it up because the coupling on the 3" drain stack was installed after the sink base was set into position.
My plan, as of now is to install a 3" to 2" bushing into the coupling and then use two 2" street 45's to offset the drain stack to the left of the hot supply. This would probably offset the drain about 2" to 2 1/2". Any reason why this wouldn't work?
As far as I know, there was never a provision for a vent at this location. There are at least two vents I've seen in the attic exiting through the roof but I have no idea where they tie into the system. My plan is to go vertical from the two street 45's into a sanitary tee for the P trap connection and then extended vertically above the tee with a Studor (AAV) vent. I'm also considering installing a cleanout tee (or wye) above the street 45's but below the sanitary tee. I just don't know if I'll have enough space beneath the sink for both tee's and the AAV.
The 3" stack with the tee that's pictured is what was removed from the previous installation. I've only included it for illustrative purposes.
Thanks.
