I may have mentioned in another thread that I discovered the previous owners screwed up when renovating my bathroom by cutting through a joist for the tub's drain. I thought it was just notched, but last time I crawled under there (sans camera) I discovered it is cut all the way through. I can only see the P-trap coming down from the overflow so it must be an above-the-floor drain & the tub shoe is not visible.
I want to correct the issue by removing the existing P-trap and modifying the setup to have a direct drain. So, instead of having the P-trap below the overflow, it will be below the tub's drain & the overflow will go to the tub drain. I'll have to cut a hole in the floor to access the tub's drain (it's 1st floor on house on blocks-- below is just dirt). I want to put a block inside the cutout in the joist to fill the void & sister it up with another joist.
I want to make sure I get all of the right parts and configure it correctly.
So, instead of a tub shoe I'm thinking of getting a Westbrass 1-1/2" straight adapter (https://www.amazon.com/Westbrass-442P-ABS-Adapter-White/dp/B01MU7ECKA/)
Getting some sort of tub to drain gasket/washer to go under the tub but above the adapter, I'll need an appropriate drain to thread in from the top (thinking of using pipe dope on the female end and teflon tape on the male end). For the overflow I need to find just the piece that connects to the back of the tub's overflow, a gasket for it, the overflow cover (thinking a Watco innovator type that has no visible screws), and I'm debating whether I need a long sweep or a shorter elbow (I'm leaning toward long sweep). I'll bring them together with a sanitary tee (sweep going down). Underneath that I will have a 2"x1-1/2"x1-1/2" sanitary tee hub to make my P-trap 2" for better drainage. It will only have to run a few feet before I can run a vent up inside the adjacent wall and merge it with an existing vent by branching over.
Any recommendations on tub drain gaskets? Or overflow gaskets? I'm having a hard time just finding the overflow part without the rest of the assembly.
I saw a kit somewhere that could be put together in different ways so it could have the regular overflow setup or direct drain but I didn't like that it wasn't a sanitary tee for one of the pieces. I'll have to find it again, but it's 2am & I just got nagged to go make dinner.
I'll try to add sketches/pictures later.
