City sewer/bathroom

Advice on doing it right! Could use a little guidence here. While googling I found another very helpful post on here so I thought I would lay out my project for expert guidence.

​​​​​​The washing machine dumps into the kitchen sink drain (with dishwasher) and runs under the house. I discovered this pipe is broken about a foot underground. I sent a cemta down but it got to foggy for me to make sense of anything. I strongly suspect it still goes to the old septic system which was switched to city sewer 15-20 years ago. The bathroom was also redone at that time and that's tied into the city sewer.

MY thoughts are to redo the entire kitchen setup and have shoot over to the city sewer at the bathroom completely eliminating the septic system. Also redoing water ones but already have that figured out.

Also, We have had issues whenever a decent amount of toilet paper is used about 10 feet out. I now believe I see where the problem is so Im thinking this will all probably need to be redone and have the run from the kitchen tie in.

What's the best way to make this happen?

That's going to be tough. Theoretically, you can just drain the sink drain into that 3" pipe, but you're going to have to cut out and replace parts of those fittings to add a wye. You might be able to tie in after the bathtub wye, but it messes a bit with the bathroom group venting.

Also the tie-in from the washer into the kitchen drain is incorrect as you're creating a wet vent. While it could cause some draining issues - it's definitely not causing the problems you're experiencing now.
