Need some help fixing my kitchen sink drain...
So apparently a previous plumber really screwed up.
In my diagram, they made the blue circled part too long, which put pressure on the red circled elbow and that broke. Plumber was there years ago and don't go into the crawl space often.
Apparently the plastic nut that is supposed to sit above the floor got shoved through so nothing is supporting the drain above the floor. The drain separated below the sink now but that should be an easy fix once the rest is secured.
Since the blue circled part was too long, it caused a negative flow and clogged up the horizontal lower part.
How would I best proceed to secure the drain above the floor?
I'm thinking about cutting off the lower horizontal part to make it a bit shorter to allow a positive flow out and eliminate the clogged part.
I'm a noob as far as plumbing goes.
