Sink to cleanout.

(question deleted)
Nevermind then.
I’ll try a plumbing DIY board.

Frankly if plumbers weren’t so overpriced in my location I’d gladly use one. But I have a budget I need to stick to and I can’t afford to drop a grand on something simple as this.

I would recommend hiring a qualified plumber that knows the local codes so it is done properly.

Ditto.

Was there a question?
